Coronavirus disease 2019 (COVID-19)

COVID-19, also called coronavirus disease 2019, is an illness caused by a virus. The virus is called severe acute respiratory syndrome coronavirus 2, or more commonly, SARS-CoV-2. It started spreading at the end of 2019 and became a pandemic disease in 2020.

Coronavirus

Coronaviruses are a family of viruses. These viruses cause illnesses such as the common cold, severe acute respiratory syndrome (SARS), Middle East respiratory syndrome (MERS) and coronavirus disease 2019 (COVID-19).

The virus that causes COVID-19 spreads most commonly through the air in tiny droplets of fluid between people in close contact. Many people with COVID-19 have no symptoms or mild illness. But for older adults and people with certain medical conditions, COVID-19 can lead to the need for care in the hospital or death.

Staying up to date on your COVID-19 vaccine helps prevent serious illness, the need for hospital care due to COVID-19 and death from COVID-19 . Other ways that may help prevent the spread of this coronavirus includes good indoor air flow, physical distancing, wearing a mask in the right setting and good hygiene.

Medicine can limit the seriousness of the viral infection. Most people recover without long-term effects, but some people have symptoms that continue for months.

Typical COVID-19 symptoms often show up 2 to 14 days after contact with the virus.

Symptoms can include:

Shortness of breath.
Loss of taste or smell.
Extreme tiredness, called fatigue.
Digestive symptoms such as upset stomach, vomiting or loose stools, called diarrhea.
Pain, such as headaches and body or muscle aches.
Fever or chills.
Cold-like symptoms such as congestion, runny nose or sore throat.

People may only have a few symptoms or none. People who have no symptoms but test positive for COVID-19 are called asymptomatic. For example, many children who test positive don't have symptoms of COVID-19 illness. People who go on to have symptoms are considered presymptomatic. Both groups can still spread COVID-19 to others.

Some people may have symptoms that get worse about 7 to 14 days after symptoms start.

Most people with COVID-19 have mild to moderate symptoms. But COVID-19 can cause serious medical complications and lead to death. Older adults or people who already have medical conditions are at greater risk of serious illness.

COVID-19 may be a mild, moderate, severe or critical illness.

In broad terms, mild COVID-19 doesn't affect the ability of the lungs to get oxygen to the body.
In moderate COVID-19 illness, the lungs also work properly but there are signs that the infection is deep in the lungs.
Severe COVID-19 means that the lungs don't work correctly, and the person needs oxygen and other medical help in the hospital.
Critical COVID-19 illness means the lung and breathing system, called the respiratory system, has failed and there is damage throughout the body.

Rarely, people who catch the coronavirus can develop a group of symptoms linked to inflamed organs or tissues. The illness is called multisystem inflammatory syndrome. When children have this illness, it is called multisystem inflammatory syndrome in children, shortened to MIS -C. In adults, the name is MIS -A.

When to see a doctor

Contact a healthcare professional if you test positive for COVID-19 . If you have symptoms and need to test for COVID-19 , or you've been exposed to someone with COVID-19 , a healthcare professional can help.

People who are at high risk of serious illness may get medicine to block the spread of the COVID-19 virus in the body. Or your healthcare team may plan regular checks to monitor your health.

Get emergency help right away for any of these symptoms:

Can't catch your breath or have problems breathing.
Skin, lips or nail beds that are pale, gray or blue.
New confusion.
Trouble staying awake or waking up.
Chest pain or pressure that is constant.

This list doesn't include every emergency symptom. If you or a person you're taking care of has symptoms that worry you, get help. Let the healthcare team know about a positive test for COVID-19 or symptoms of the illness.

COVID-19 is caused by infection with the severe acute respiratory syndrome coronavirus 2, also called SARS-CoV-2.

The coronavirus spreads mainly from person to person, even from someone who is infected but has no symptoms. When people with COVID-19 cough, sneeze, breathe, sing or talk, their breath may be infected with the COVID-19 virus.

The coronavirus carried by a person's breath can land directly on the face of a nearby person, after a sneeze or cough, for example. The droplets or particles the infected person breathes out could possibly be breathed in by other people if they are close together or in areas with low air flow. And a person may touch a surface that has respiratory droplets and then touch their face with hands that have the coronavirus on them.

It's possible to get COVID-19 more than once.

Over time, the body's defense against the COVID-19 virus can fade.
A person may be exposed to so much of the virus that it breaks through their immune defense.
As a virus infects a group of people, the virus copies itself. During this process, the genetic code can randomly change in each copy. The changes are called mutations. If the coronavirus that causes COVID-19 changes in ways that make previous infections or vaccination less effective at preventing infection, people can get sick again.

The virus that causes COVID-19 can infect some pets. Cats, dogs, hamsters and ferrets have caught this coronavirus and had symptoms. It's rare for a person to get COVID-19 from a pet.

Risk factors

The main risk factors for COVID-19 are:

If someone you live with has COVID-19 .
If you spend time in places with poor air flow and a higher number of people when the virus is spreading.
If you spend more than 30 minutes in close contact with someone who has COVID-19 .

Many factors affect your risk of catching the virus that causes COVID-19 . How long you are in contact, if the space has good air flow and your activities all affect the risk. Also, if you or others wear masks, if someone has COVID-19 symptoms and how close you are affects your risk. Close contact includes sitting and talking next to one another, for example, or sharing a car or bedroom.

It seems to be rare for people to catch the virus that causes COVID-19 from an infected surface. While the virus is shed in waste, called stool, COVID-19 infection from places such as a public bathroom is not common.

Serious COVID-19 illness risk factors

Some people are at a higher risk of serious COVID-19 illness than others. This includes people age 65 and older as well as babies younger than 6 months. Those age groups have the highest risk of needing hospital care for COVID-19 .

Not every risk factor for serious COVID-19 illness is known. People of all ages who have no other medical issues have needed hospital care for COVID-19 .

Known risk factors for serious illness include people who have not gotten a COVID-19 vaccine. Serious illness also is a higher risk for people who have:

Sickle cell disease or thalassemia.
Serious heart diseases and possibly high blood pressure.
Chronic kidney, liver or lung diseases.

People with dementia or Alzheimer's also are at higher risk, as are people with brain and nervous system conditions such as stroke. Smoking increases the risk of serious COVID-19 illness. And people with a body mass index in the overweight category or obese category may have a higher risk as well.

Other medical conditions that may raise the risk of serious illness from COVID-19 include:

Cancer or a history of cancer.
Type 1 or type 2 diabetes.
Weakened immune system from solid organ transplants or bone marrow transplants, some medicines, or HIV .

This list is not complete. Factors linked to a health issue may raise the risk of serious COVID-19 illness too. Examples are a medical condition where people live in a group home, or lack of access to medical care. Also, people with more than one health issue, or people of older age who also have health issues have a higher chance of severe illness.

Complications

Complications of COVID-19 include long-term loss of taste and smell, skin rashes, and sores. The illness can cause trouble breathing or pneumonia. Medical issues a person already manages may get worse.

Complications of severe COVID-19 illness can include:

Acute respiratory distress syndrome, when the body's organs do not get enough oxygen.
Shock caused by the infection or heart problems.
Overreaction of the immune system, called the inflammatory response.
Blood clots.
Kidney injury.

Post-COVID-19 syndrome

After a COVID-19 infection, some people report that symptoms continue for months, or they develop new symptoms. This syndrome has often been called long COVID, or post- COVID-19 . You might hear it called long haul COVID-19 , post-COVID conditions or PASC. That's short for post-acute sequelae of SARS -CoV-2.

Other infections, such as the flu and polio, can lead to long-term illness. But the virus that causes COVID-19 has only been studied since it began to spread in 2019. So, research into the specific effects of long-term COVID-19 symptoms continues.

Researchers do think that post- COVID-19 syndrome can happen after an illness of any severity.

Getting a COVID-19 vaccine may help prevent post- COVID-19 syndrome.

Long-term effects of COVID-19

The Centers for Disease Control and Prevention (CDC) recommends a COVID-19 vaccine for everyone age 6 months and older. The COVID-19 vaccine can lower the risk of death or serious illness caused by COVID-19. It lowers your risk and lowers the risk that you may spread it to people around you.

The COVID-19 vaccines available in the United States are:

2023-2024 Pfizer-BioNTech COVID-19 vaccine. This vaccine is available for people age 6 months and older.

Among people with a typical immune system:

Children age 6 months up to age 4 years are up to date after three doses of a Pfizer-BioNTech COVID-19 vaccine.
People age 5 and older are up to date after one Pfizer-BioNTech COVID-19 vaccine.
For people who have not had a 2023-2024 COVID-19 vaccination, the CDC recommends getting an additional shot of that updated vaccine.

2023-2024 Moderna COVID-19 vaccine. This vaccine is available for people age 6 months and older.

Children ages 6 months up to age 4 are up to date if they've had two doses of a Moderna COVID-19 vaccine.
People age 5 and older are up to date with one Moderna COVID-19 vaccine.

2023-2024 Novavax COVID-19 vaccine. This vaccine is available for people age 12 years and older.

People age 12 years and older are up to date if they've had two doses of a Novavax COVID-19 vaccine.

In general, people age 5 and older with typical immune systems can get any vaccine approved or authorized for their age. They usually don't need to get the same vaccine each time.

Some people should get all their vaccine doses from the same vaccine maker, including:

Children ages 6 months to 4 years.
People age 5 years and older with weakened immune systems.
People age 12 and older who have had one shot of the Novavax vaccine should get the second Novavax shot in the two-dose series.

Talk to your healthcare professional if you have any questions about the vaccines for you or your child. Your healthcare team can help you if:

The vaccine you or your child got earlier isn't available.
You don't know which vaccine you or your child received.
You or your child started a vaccine series but couldn't finish it due to side effects.

People with weakened immune systems

Your healthcare team may suggest added doses of COVID-19 vaccine if you have a moderately or seriously weakened immune system. The FDA has also authorized the monoclonal antibody pemivibart (Pemgarda) to prevent COVID-19 in some people with weakened immune systems.

Control the spread of infection

In addition to vaccination, there are other ways to stop the spread of the virus that causes COVID-19 .

If you are at a higher risk of serious illness, talk to your healthcare professional about how best to protect yourself. Know what to do if you get sick so you can quickly start treatment.

If you feel ill or have COVID-19 , stay home and away from others, including pets, if possible. Avoid sharing household items such as dishes or towels if you're sick.

In general, make it a habit to:

Test for COVID-19 . If you have symptoms of COVID-19 test for the infection. Or test five days after you came in contact with the virus.
Help from afar. Avoid close contact with anyone who is sick or has symptoms, if possible.
Wash your hands. Wash your hands well and often with soap and water for at least 20 seconds. Or use an alcohol-based hand sanitizer with at least 60% alcohol.
Cover your coughs and sneezes. Cough or sneeze into a tissue or your elbow. Then wash your hands.
Clean and disinfect high-touch surfaces. For example, clean doorknobs, light switches, electronics and counters regularly.

Try to spread out in crowded public areas, especially in places with poor airflow. This is important if you have a higher risk of serious illness.

The CDC recommends that people wear a mask in indoor public spaces if you're in an area with a high number of people with COVID-19 in the hospital. They suggest wearing the most protective mask possible that you'll wear regularly, that fits well and is comfortable.

Travel and COVID-19

Travel brings people together from areas where illnesses may be at higher levels. Masks can help slow the spread of respiratory diseases in general, including COVID-19 . Masks help the most in places with low air flow and where you are in close contact with other people. Also, masks can help if the places you travel to or through have a high level of illness.

Masking is especially important if you or a companion have a high risk of serious illness from COVID-19 .

Experts say students should be honest and not limit themselves to merely their experiences with the pandemic.

The global impact of COVID-19, the disease caused by the novel coronavirus, means colleges and prospective students alike are in for an admissions cycle like no other. Both face unprecedented challenges and questions as they grapple with their respective futures amid the ongoing fallout of the pandemic.

Colleges must examine applicants without the aid of standardized test scores for many – a factor that prompted many schools to go test-optional for now . Even grades, a significant component of a college application, may be hard to interpret with some high schools adopting pass-fail classes last spring due to the pandemic. Major college admissions factors are suddenly skewed.

"I can't help but think other (admissions) factors are going to matter more," says Ethan Sawyer, founder of the College Essay Guy, a website that offers free and paid essay-writing resources.

College essays and letters of recommendation , Sawyer says, are likely to carry more weight than ever in this admissions cycle. And many essays will likely focus on how the pandemic shaped students' lives throughout an often tumultuous 2020.

But before writing a college essay focused on the coronavirus, students should explore whether it's the best topic for them.

Writing About COVID-19 for a College Application

Much of daily life has been colored by the coronavirus. Virtual learning is the norm at many colleges and high schools, many extracurriculars have vanished and social lives have stalled for students complying with measures to stop the spread of COVID-19.

"For some young people, the pandemic took away what they envisioned as their senior year," says Robert Alexander, dean of admissions, financial aid and enrollment management at the University of Rochester in New York. "Maybe that's a spot on a varsity athletic team or the lead role in the fall play. And it's OK for them to mourn what should have been and what they feel like they lost, but more important is how are they making the most of the opportunities they do have?"

That question, Alexander says, is what colleges want answered if students choose to address COVID-19 in their college essay.

But the question of whether a student should write about the coronavirus is tricky. The answer depends largely on the student.

"In general, I don't think students should write about COVID-19 in their main personal statement for their application," Robin Miller, master college admissions counselor at IvyWise, a college counseling company, wrote in an email.

"Certainly, there may be exceptions to this based on a student's individual experience, but since the personal essay is the main place in the application where the student can really allow their voice to be heard and share insight into who they are as an individual, there are likely many other topics they can choose to write about that are more distinctive and unique than COVID-19," Miller says.

Opinions among admissions experts vary on whether to write about the likely popular topic of the pandemic.

"If your essay communicates something positive, unique, and compelling about you in an interesting and eloquent way, go for it," Carolyn Pippen, principal college admissions counselor at IvyWise, wrote in an email. She adds that students shouldn't be dissuaded from writing about a topic merely because it's common, noting that "topics are bound to repeat, no matter how hard we try to avoid it."

Above all, she urges honesty.

"If your experience within the context of the pandemic has been truly unique, then write about that experience, and the standing out will take care of itself," Pippen says. "If your experience has been generally the same as most other students in your context, then trying to find a unique angle can easily cross the line into exploiting a tragedy, or at least appearing as though you have."

But focusing entirely on the pandemic can limit a student to a single story and narrow who they are in an application, Sawyer says. "There are so many wonderful possibilities for what you can say about yourself outside of your experience within the pandemic."

He notes that passions, strengths, career interests and personal identity are among the multitude of essay topic options available to applicants and encourages them to probe their values to help determine the topic that matters most to them – and write about it.

That doesn't mean the pandemic experience has to be ignored if applicants feel the need to write about it.

Writing About Coronavirus in Main and Supplemental Essays

Students can choose to write a full-length college essay on the coronavirus or summarize their experience in a shorter form.

To help students explain how the pandemic affected them, The Common App has added an optional section to address this topic. Applicants have 250 words to describe their pandemic experience and the personal and academic impact of COVID-19.

"That's not a trick question, and there's no right or wrong answer," Alexander says. Colleges want to know, he adds, how students navigated the pandemic, how they prioritized their time, what responsibilities they took on and what they learned along the way.

If students can distill all of the above information into 250 words, there's likely no need to write about it in a full-length college essay, experts say. And applicants whose lives were not heavily altered by the pandemic may even choose to skip the optional COVID-19 question.

"This space is best used to discuss hardship and/or significant challenges that the student and/or the student's family experienced as a result of COVID-19 and how they have responded to those difficulties," Miller notes. Using the section to acknowledge a lack of impact, she adds, "could be perceived as trite and lacking insight, despite the good intentions of the applicant."

To guard against this lack of awareness, Sawyer encourages students to tap someone they trust to review their writing , whether it's the 250-word Common App response or the full-length essay.

Experts tend to agree that the short-form approach to this as an essay topic works better, but there are exceptions. And if a student does have a coronavirus story that he or she feels must be told, Alexander encourages the writer to be authentic in the essay.

"My advice for an essay about COVID-19 is the same as my advice about an essay for any topic – and that is, don't write what you think we want to read or hear," Alexander says. "Write what really changed you and that story that now is yours and yours alone to tell."

Sawyer urges students to ask themselves, "What's the sentence that only I can write?" He also encourages students to remember that the pandemic is only a chapter of their lives and not the whole book.

Miller, who cautions against writing a full-length essay on the coronavirus, says that if students choose to do so they should have a conversation with their high school counselor about whether that's the right move. And if students choose to proceed with COVID-19 as a topic, she says they need to be clear, detailed and insightful about what they learned and how they adapted along the way.

"Approaching the essay in this manner will provide important balance while demonstrating personal growth and vulnerability," Miller says.

Pippen encourages students to remember that they are in an unprecedented time for college admissions.

"It is important to keep in mind with all of these (admission) factors that no colleges have ever had to consider them this way in the selection process, if at all," Pippen says. "They have had very little time to calibrate their evaluations of different application components within their offices, let alone across institutions. This means that colleges will all be handling the admissions process a little bit differently, and their approaches may even evolve over the course of the admissions cycle."

COVID-19 Pandemic

By: History.com Editors

Updated: March 11, 2024 | Original: April 25, 2023

The outbreak of the infectious respiratory disease known as COVID-19 triggered one of the deadliest pandemics in modern history. COVID-19 claimed nearly 7 million lives worldwide. In the United States, deaths from COVID-19 exceeded 1.1 million, nearly twice the American death toll from the 1918 flu pandemic . The COVID-19 pandemic also took a heavy toll economically, politically and psychologically, revealing deep divisions in the way that Americans viewed the role of government in a public health crisis, particularly vaccine mandates. While the United States downgraded its “national emergency” status over the pandemic on May 11, 2023, the full effects of the COVID-19 pandemic will reverberate for decades.

A New Virus Breaks Out in Wuhan, China

In December 2019, the China office of the World Health Organization (WHO) received news of an isolated outbreak of a pneumonia-like virus in the city of Wuhan. The virus caused high fevers and shortness of breath, and the cases seemed connected to the Huanan Seafood Wholesale Market in Wuhan, which was closed by an emergency order on January 1, 2020.

After testing samples of the unknown virus, the WHO identified it as a novel type of coronavirus similar to the deadly SARS virus that swept through Asia from 2002-2004. The WHO named this new strain SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2). The first Chinese victim of SARS-CoV-2 died on January 11, 2020.

Where, exactly, the novel virus originated has been hotly debated. There are two leading theories. One is that the virus jumped from animals to humans, possibly carried by infected animals sold at the Wuhan market in late 2019. A second theory claims the virus escaped from the Wuhan Institute of Virology, a research lab that was studying coronaviruses. U.S. intelligence agencies maintain that both origin stories are “plausible.”

The First COVID-19 Cases in America

The WHO hoped that the virus outbreak would be contained to Wuhan, but by mid-January 2020, infections were reported in Thailand, Japan and Korea, all from people who had traveled to China.

On January 18, 2020, a 35-year-old man checked into an urgent care center near Seattle, Washington. He had just returned from Wuhan and was experiencing a fever, nausea and vomiting. On January 21, he was identified as the first American infected with SARS-CoV-2.

In reality, dozens of Americans had contracted SARS-CoV-2 weeks earlier, but doctors didn’t think to test for a new type of virus. One of those unknowingly infected patients died on February 6, 2020, but her death wasn’t confirmed as the first American casualty until April 21.

On February 11, 2020, the WHO released a new name for the disease causing the deadly outbreak: Coronavirus Disease 2019 or COVID-19. By mid-March 2020, all 50 U.S. states had reported at least one positive case of COVID-19, and nearly all of the new infections were caused by “community spread,” not by people who contracted the disease while traveling abroad.

At the same time, COVID-19 had spread to 114 countries worldwide, killing more than 4,000 people and infecting hundreds of thousands more. On March 11, the WHO made it official and declared COVID-19 a pandemic.

The World Shuts Down

New York City's famous Times Square is seen nearly empty due to the COVID-19 pandemic on March 16, 2020.

Pandemics are expected in a globally interconnected world, so emergency plans were in place. In the United States, health officials at the Centers for Disease Control and Prevention (CDC) and the National Institutes of Health (NIH) set in motion a national response plan developed for flu pandemics.

State by state and city by city, government officials took emergency measures to encourage “ social distancing ,” one of the many new terms that became part of the COVID-19 vocabulary. Travel was restricted. Schools and churches were closed. With the exception of “essential workers,” all offices and businesses were shuttered. By early April 2020, more than 316 million Americans were under a shelter-in-place or stay-at-home order.

With more than 1,000 deaths and nearly 100,000 cases, it was clear by April 2020 that COVID-19 was highly contagious and virulent. What wasn’t clear, even to public health officials, was how individuals could best protect themselves from COVID-19. In the early weeks of the outbreak, the CDC discouraged people from buying face masks, because officials feared a shortage of masks for doctors and hospital workers.

By April 2020, the CDC revised its recommendations, encouraging people to wear masks in public, to socially distance and to wash hands frequently. President Donald Trump undercut the CDC recommendations by emphasizing that masking was voluntary and vowing not to wear a mask himself. This was just the beginning of the political divisions that hobbled the COVID-19 response in America.

Global Financial Markets Collapse

In the early months of the COVID-19 pandemic, with billions of people worldwide out of work, stuck at home, and fretting over shortages of essential items like toilet paper , global financial markets went into a tailspin.

In the United States, share prices on the New York Stock Exchange plummeted so quickly that the exchange had to shut down trading three separate times. The Dow Jones Industrial Average eventually lost 37 percent of its value, and the S&P 500 was down 34 percent.

Business closures and stay-at-home orders gutted the U.S. economy. The unemployment rate skyrocketed, particularly in the service sector (restaurant and other retail workers). By May 2020, the U.S. unemployment rate reached 14.7 percent, the highest jobless rate since the Great Depression .

All across America, households felt the pinch of lost jobs and lower wages. Food insecurity reached a peak by December 2020 with 30 million American adults—a full 14 percent—reporting that their families didn’t get enough to eat in the past week.

The economic effects of the COVID-19 pandemic, like its health effects, weren’t experienced equally. Black, Hispanic and Native Americans suffered from unemployment and food insecurity at significantly higher rates than white Americans.

Congress tried to avoid a complete economic collapse by authorizing a series of COVID-19 relief packages in 2020 and 2021, which included direct stimulus checks for all American families.

The Race for a Vaccine

A new vaccine typically takes 10 to 15 years to develop and test, but the world couldn’t wait that long for a COVID-19 vaccine. The U.S. Department of Health and Human Services (HHS) under the Trump administration launched “ Operation Warp Speed ,” a public-private partnership which provided billions of dollars in upfront funding to pharmaceutical companies to rapidly develop vaccines and conduct clinical trials.

The first clinical trial for a COVID-19 vaccine was announced on March 16, 2020, only days after the WHO officially classified COVID-19 as a pandemic. The vaccines developed by Moderna and Pfizer were the first ever to employ messenger RNA, a breakthrough technology. After large-scale clinical trials, both vaccines were found to be greater than 95 percent effective against infection with COVID-19.

A nurse from New York officially became the first American to receive a COVID-19 vaccine on December 14, 2020. Ten days later, more than 1 million vaccines had been administered, starting with healthcare workers and elderly residents of nursing homes. As the months rolled on, vaccine availability was expanded to all American adults, and then to teenagers and all school-age children.

By the end of the pandemic in early 2023, more than 670 million doses of COVID-19 vaccines had been administered in the United States at a rate of 203 doses per 100 people. Approximately 80 percent of the U.S. population received at least one COVID-19 shot, but vaccination rates were markedly lower among Black, Hispanic and Native Americans.

COVID-19 Deaths Heaviest Among Elderly and People of Color

In America, the COVID-19 pandemic impacted everyone’s lives, but those who died from the disease were far more likely to be older and people of color.

Of the more than 1.1 million COVID deaths in the United States, 75 percent were individuals who were 65 or older. A full 93 percent of American COVID-19 victims were 50 or older. Throughout the emergence of COVID-19 variants and the vaccine rollouts, older Americans remained the most at-risk for being hospitalized and ultimately dying from the disease.

Black, Hispanic and Native Americans were also at a statistically higher risk of developing life-threatening COVID-19 systems and succumbing to the disease. For example, Black and Hispanic Americans were twice as likely to be hospitalized from COVID-19 than white Americans. The COVID-19 pandemic shined light on the health disparities between racial and ethnic groups driven by systemic racism and lower access to healthcare.

Mental health also worsened during the COVID-19 pandemic. The anxiety of contracting the disease, and the stresses of being unemployed or confined at home, led to unprecedented numbers of Americans reporting feelings of depression and suicidal ideation.

A Time of Social & Political Upheaval

Thousands gather for the ''Get Your Knee Off Our Necks'' march in Washington DC USA, on August 28, 2020.

In the United States, the three long years of the COVID-19 pandemic paralleled a time of heightened political contention and social upheaval.

When George Floyd was killed by Minneapolis police on May 25, 2020, it sparked nationwide protests against police brutality and energized the Black Lives Matter movement. Because so many Americans were out of work or home from school due to COVID-19 shutdowns, unprecedented numbers of people from all walks of life took to the streets to demand reforms.

Instead of banding together to slow the spread of the disease, Americans became sharply divided along political lines in their opinions of masking requirements, vaccines and social distancing.

By March 2024, in signs that the pandemic was waning, the CDC issued new guidelines for people who were recovering from COVID-19. The agency said those infected with the virus no longer needed to remain isolated for five days after symptoms. And on March 10, 2024, the Johns Hopkins Coronavirus Resource Center stopped collecting data for its highly referenced COVID-19 dashboard.

Still, an estimated 17 percent of U.S. adults reported having experienced symptoms of long COVID, according to the Household Pulse Survey. The medical community is still working to understand the causes behind long COVID, which can afflict a patient for weeks, months or even years.

A Deep Look into the Biology and Evolution of COVID-19

Uctv roundtable explores the biological roots and spread of the global sars-cov-2 virus.

Of the hundreds of coronaviruses known to exist, many are relatively harmless. Coronaviruses infect your nose, sinuses and upper throat but often result in nothing more than a common cold (see Know Your Coronaviruses ).

So what makes the new SARS-CoV-2, the virus that has caused a global pandemic, such a society-altering threat?

Probing the biological basis of the novel virus and evolutionary spread of the COVID-19 disease it causes, a panel of UC San Diego biologists gathered for a special roundtable analysis hosted by UCTV. The program is available here: A Deep Look into the Biology and Evolution of COVID-19.

Roundtable moderator Suresh Subramani, distinguished professor emeritus in the Division of Biological Sciences and director of the Tata Institute for Genetics and Society, framed the program by highlighting three major areas of concern surrounding the pandemic and how it impacts our daily lives: the rapid spread of the virus over the past three months; the ominous morbidity and mortality rates of the disease, which threaten to overwhelm global health care systems; and the immense reservoir of carriers of the disease.

“It is estimated that there may be tenfold more asymptomatic carriers of the disease, which means that there could be over seven-and-a-half million carriers worldwide,” said Subramani. “This is a disease that is spreading very rapidly across the globe, so these faculty are here to share their knowledge regarding the biology of the virus and why this pandemic has brought the world to its knees.”

Emily Troemel, a professor who studies host-pathogen interactions in the Section of Cell and Developmental Biology, kicked off the discussion by describing basic biological aspects of coronaviruses, including how health workers test for the presence of SARS-CoV-2 infection and facets scientists have learned about the virus’ genome.

Coronaviruses, as Troemel noted, feature RNA-based genomes, unlike most of life on the planet, which feature DNA genomes. RNA genomes in coronaviruses are positive-sense, which are similar to the cell’s own messenger RNA and allows these viruses to immediately hijack the protein synthesis machinery of host cells. This feature enables these viruses to quickly and effectively take over host cells and rapidly expand.

“Knowing that it has RNA in its genome helps us understand how we test for the presence of coronavirus,” said Troemel. “In addition, we are able to look at changes in the sequence in the viral genome and that’s enabling us to track the spread of this virus around the globe…. We can learn about how the biology of the virus is changing and how it may be altering the way it interacts with host cells, and also potentially different ways that we could treat it. It’s part of an amazing open science effort with an unprecedented level of information acquisition and information sharing among researchers.”

Matt Daugherty, an assistant professor in the Section of Molecular Biology, studies the evolutionary arms race that pits the immune systems of hosts on one hand and pathogens on the other. He covered aspects such as how SARS-CoV-2 and other viruses enter the human population and become pandemics; how SARS-CoV-2 relates to past and present epidemic viruses in the human population; and, based on what scientists have learned from other viruses, what we can expect in terms of long-term immunity and co-existence with SARS-CoV-2.

“We as a species are always being exposed to viruses,” Daugherty noted.

Since SARS-CoV-2 is so new, there are many key unknowns related to human immune defenses against it, Daugherty said. Even with coronaviruses that cause common colds, it’s unclear whether humans develop long-term immunity to these viruses or need to continually develop new immunities.

“One thing I take comfort in with all of these other viruses is knowing that we aren’t constantly dealing with influenza pandemics and other pandemic viruses, and that’s because of the largely effective role of our immune system in dealing with these viruses once the immune system has been prepared,” said Daugherty.

For a virus that originated in an animal species to successfully infect humans, it needs to adapt to a range of genetic differences between the original host species and humans. But effective vaccines can ultimately thwart such pathogens.

“We have really good ways of making effective vaccines, and the hope is that this will hold for SARS-CoV-2 as well,” said Daugherty. “I take some comfort in knowing that these types of pandemics do pass and we will get through this.”

Justin Meyer, an assistant professor in the Section of Ecology, Behavior and Evolution, discussed concepts related to science and society’s ability to predict future pandemics. These include variables that contribute to the spread of pathogens; the increased likelihood of future pandemics; and predictions for where the next pandemic is likely to occur.

Factors that boost the risk of pandemics include human exposure to pathogens through meat consumption and contact with wild animals, increased human encroachment in wild areas and the exotic animal trade. Increased urbanization—more people living in close proximity means more opportunities for viruses to spread—and the rising consequences of climate change, also increase pandemic risks.

“We’re augmenting the temperature of the earth and environments in a way that we’re making ourselves more susceptible to diseases,” said Meyer. “When we warm the earth, we create more habitats for mosquitoes that carry vectors like malaria by increasing their range. They can spread to new human populations..... By increasing temperatures, we’re increasing flooding and there are many pathogens that are waterborne, such as cholera, which we will be exposing more and more people to.”

During the roundtable discussion, Subramani prompted the scientists with a handful of questions, including: Since many coronaviruses are relatively harmless, what makes SARS-CoV-2 so damaging to the lungs? What is the appropriate vaccine target for SARS-CoV-2 and in what time frame—from validation to FDA approval—is a vaccine likely? Can we look to drug targets where vaccines have been developed for related viruses and would that timeline be the same? Is there any evidence that SARS-CoV-2 has a mutation rate that is extraordinarily high?

Covid 19 Essay in English

Essay on Covid -19: In a very short amount of time, coronavirus has spread globally. It has had an enormous impact on people's lives, economy, and societies all around the world, affecting every country. Governments have had to take severe measures to try and contain the pandemic. The virus has altered our way of life in many ways, including its effects on our health and our economy. Here are a few sample essays on ‘CoronaVirus’.

100 Words Essay on Covid 19

200 words essay on covid 19, 500 words essay on covid 19.

COVID-19 or Corona Virus is a novel coronavirus that was first identified in 2019. It is similar to other coronaviruses, such as SARS-CoV and MERS-CoV, but it is more contagious and has caused more severe respiratory illness in people who have been infected. The novel coronavirus became a global pandemic in a very short period of time. It has affected lives, economies and societies across the world, leaving no country untouched. The virus has caused governments to take drastic measures to try and contain it. From health implications to economic and social ramifications, COVID-19 impacted every part of our lives. It has been more than 2 years since the pandemic hit and the world is still recovering from its effects.

Since the outbreak of COVID-19, the world has been impacted in a number of ways. For one, the global economy has taken a hit as businesses have been forced to close their doors. This has led to widespread job losses and an increase in poverty levels around the world. Additionally, countries have had to impose strict travel restrictions in an attempt to contain the virus, which has resulted in a decrease in tourism and international trade. Furthermore, the pandemic has put immense pressure on healthcare systems globally, as hospitals have been overwhelmed with patients suffering from the virus. Lastly, the outbreak has led to a general feeling of anxiety and uncertainty, as people are fearful of contracting the disease.

My Experience of COVID-19

I still remember how abruptly colleges and schools shut down in March 2020. I was a college student at that time and I was under the impression that everything would go back to normal in a few weeks. I could not have been more wrong. The situation only got worse every week and the government had to impose a lockdown. There were so many restrictions in place. For example, we had to wear face masks whenever we left the house, and we could only go out for essential errands. Restaurants and shops were only allowed to operate at take-out capacity, and many businesses were shut down.

In the current scenario, coronavirus is dominating all aspects of our lives. The coronavirus pandemic has wreaked havoc upon people’s lives, altering the way we live and work in a very short amount of time. It has revolutionised how we think about health care, education, and even social interaction. This virus has had long-term implications on our society, including its impact on mental health, economic stability, and global politics. But we as individuals can help to mitigate these effects by taking personal responsibility to protect themselves and those around them from infection.

Effects of CoronaVirus on Education

The outbreak of coronavirus has had a significant impact on education systems around the world. In China, where the virus originated, all schools and universities were closed for several weeks in an effort to contain the spread of the disease. Many other countries have followed suit, either closing schools altogether or suspending classes for a period of time.

This has resulted in a major disruption to the education of millions of students. Some have been able to continue their studies online, but many have not had access to the internet or have not been able to afford the costs associated with it. This has led to a widening of the digital divide between those who can afford to continue their education online and those who cannot.

The closure of schools has also had a negative impact on the mental health of many students. With no face-to-face contact with friends and teachers, some students have felt isolated and anxious. This has been compounded by the worry and uncertainty surrounding the virus itself.

The situation with coronavirus has improved and schools have been reopened but students are still catching up with the gap of 2 years that the pandemic created. In the meantime, governments and educational institutions are working together to find ways to support students and ensure that they are able to continue their education despite these difficult circumstances.

Effects of CoronaVirus on Economy

The outbreak of the coronavirus has had a significant impact on the global economy. The virus, which originated in China, has spread to over two hundred countries, resulting in widespread panic and a decrease in global trade. As a result of the outbreak, many businesses have been forced to close their doors, leading to a rise in unemployment. In addition, the stock market has taken a severe hit.

Effects of CoronaVirus on Health

The effects that coronavirus has on one's health are still being studied and researched as the virus continues to spread throughout the world. However, some of the potential effects on health that have been observed thus far include respiratory problems, fever, and coughing. In severe cases, pneumonia, kidney failure, and death can occur. It is important for people who think they may have been exposed to the virus to seek medical attention immediately so that they can be treated properly and avoid any serious complications. There is no specific cure or treatment for coronavirus at this time, but there are ways to help ease symptoms and prevent the virus from spreading.

We investigate the relationship between media consumption, misinformation, and important attitudes and behaviours during the coronavirus disease 2019 (COVID-19) pandemic. We find that comparatively more misinformation circulates on Twitter, while news media tends to reinforce public health recommendations like social distancing. We find that exposure to social media is associated with misperceptions regarding basic facts about COVID-19 while the inverse is true for news media. These misperceptions are in turn associated with lower compliance with social distancing measures. We thus draw a clear link from misinformation circulating on social media, notably Twitter, to behaviours and attitudes that potentially magnify the scale and lethality of COVID-19.

Research Questions

How prevalent is misinformation surrounding COVID-19 on Twitter, and how does this compare to Canadian news media?
Does the type of media one is exposed to influence social distancing behaviours and beliefs about COVID-19?
Is there a link between COVID-19 misinformation and perceptions of the pandemic’s severity and compliance with social distancing recommendations?

Essay Summary

We evaluate the presence of misinformation and public health recommendations regarding COVID-19 in a massive corpus of tweets as well as all articles published on nineteen Canadian news sites. Using these data, we show that preventative measures are more encouraged and covered on traditional news media, while misinformation appears more frequently on Twitter.
To evaluate the impact of this greater level of misinformation, we conducted a nationally representative survey that included questions about common misperceptions regarding COVID-19, risk perceptions, social distancing compliance, and exposure to traditional news and social media. We find that being exposed to news media is associated with fewer misperceptions and more social distancing compliance while conversely, social media exposure is associated with more misperceptions and less social distancing compliance.
Misperceptions regarding the virus are in turn associated with less compliance with social distancing measures, even when controlling for a broad range of other attitudes and characteristics.
Association between social media exposure and social distancing non-compliance is eliminated when accounting for effect of misperceptions, providing evidence that social media is associated with non-compliance through increasing misperceptions about the virus.

Implications

The COVID-19 pandemic has been accompanied by a so-called “infodemic”—a global spread of misinformation that poses a serious problem for public health. Infodemics are concerning because the spread of false or misleading information has the capacity to change transmission patterns (Kim et al., 2019) and consequently the scale and lethality of a pandemic. This information can be shared by any media, but there is reason to be particularly concerned about the role that social media, such as Facebook and Twitter, play in incidentally boosting misperceptions. These platforms are increasingly relied upon as primary sources of news (Mitchell et al., 2016) and misinformation has been heavily documented on them (Garrett, 2019; Vicario et al., 2016). Scholars have found medical and health misinformation on the platforms, including that related to vaccines (Radzikowski et al., 2016) and other virus epidemics such as Ebola (Fung et al., 2016) and Zika (Sharma et al., 2017).

However, misinformation content typically makes up a low percentage of overall discussion of a topic (e.g. Fung et al., 2016) and mere exposure to misinformation does not guarantee belief in that misinformation. More research is thus needed to understand the extent and consequences of misinformation surrounding COVID-19 on social media. During the COVID-19 pandemic, Twitter, Facebook and other platforms have engaged in efforts to combat misinformation but they have continued to receive widespread criticism that misinformation is still appearing on prominent pages and groups (Kouzy et al., 2020; NewsGuard, 2020). The extent to which misinformation continues to circulate on these platforms and influence people’s attitudes and behaviours is still very much an open question.

Here, we draw on three data sets and a sequential mixed method approach to better understand the consequences of online misinformation for important behaviours and attitudes. First, we collected nearly 2.5 million tweets explicitly referring to COVID-19 in the Canadian context. Second, we collected just over 9 thousand articles from nineteen Canadian English-language news sites from the same time period. We coded both of these media sets for misinformation and public health recommendations. Third, we conducted a nationally representative survey that included questions related to media consumption habits, COVID-19 perceptions and misperceptions, and social distancing compliance. As our outcome variables are continuous, we use Ordinary Least Squares (OLS) regression to identify relationships between news and social media exposure, misperceptions, compliance with social distancing measures, and risk perceptions. We use these data to illustrate: 1) the relative prevalence of misinformation on Twitter; and 2) a powerful association between social media usage and misperceptions, on the one hand, and social distancing non-compliance on the other.

Misinformation and compliance with social distancing

We first compare the presence of misinformation on Twitter with that on news media and find, consistent with the other country cases (Chadwick & Vaccari, 2019; Vicario et al., 2016), comparatively higher levels of misinformation circulating on the social media platform. We also found that recommendations for safe practices during the pandemic (e.g. washing hands, social distancing) appeared much more frequently in the Canadian news media. These findings are in line with literature examining fake news which finds a large difference in information quality across media (Al-Rawi, 2019; Guess & Nyhan, 2018).

Spending time in a media environment that contains misinformation is likely to change attitudes and behaviours. Even if users are not nested in networks that propagate misinformation, they are likely to be incidentally exposed to information from a variety of perspectives (Feezell, 2018; Fletcher & Nielsen, 2018; Weeks et al., 2017). Even a highly curated social media feed is thus still likely to contain misinformation. As cumulative exposure to misinformation increases, users are likely to experience a reinforcement effect whereby familiarity leads to stronger belief (Dechêne et al., 2010).

To evaluate this empirically, we conducted a national survey that included questions on information consumption habits and a battery of COVID-19 misperceptions that could be the result of exposure to misinformation. We find that those who self-report exposure to the misinformation-rich social media environment do tend to have more misperceptions regarding COVID-19. These findings are consistent with others that link exposure to misinformation and misperceptions (Garrett et al., 2016; Jamieson & Albarracín, 2020). Social media users also self-report less compliance with social distancing.

Misperceptions are most meaningful when they impact behaviors in dangerous ways. During a pandemic, misperceptions can be fatal. In this case, we find that misperceptions are associated with reduced COVID-19 risk perceptions and with lower compliance with social distancing measures. We continue to find strong effects after controlling for socio-economic characteristics as well as scientific literacy. After accounting for the effect of misperceptions on social distancing non-compliance, social media usage no longer has a significant association with non-compliance, providing evidence that social media may lead to less social distancing compliance through its effect on COVID-19 misperceptions.

While some social media companies have made efforts to suppress misinformation on their platforms, there continues to be a high level of misinformation relative to news media. Highly polarized political environments and media ecosystems can lead to the spread of misinformation, such as in the United States during the COVID-19 pandemic (Allcott et al., 2020; Motta et al., 2020). But even in healthy media ecosystems with less partisan news (Owen et al., 2020), social media can continue to facilitate the spread of misinformation. There is a real danger that without concerted efforts to reduce the amount of misinformation shared on social media, the large-scale social efforts required to combat COVID-19 will be undermined.

We contribute to a growing base of evidence that misinformation circulating on social media poses public health risks and join others in calling for social media companies to put greater focus on flattening the curve of misinformation (Donovan, 2020). These findings also provide governments with stronger evidence that the misinformation circulating on social media can be directly linked to misperceptions and public health risks. Such evidence is essential for them to chart an effective policy course. Finally, the methods and approach developed in this paper can be fruitfully applied to study other waves of misinformation and the research community can build upon the link clearly drawn between misinformation exposure, misperceptions, and downstream attitudes and behaviours.

We found use of social media platforms broadly contributes to misperceptions but were unable to precise the overall level of misinformation circulating on non-Twitter social media. Data access for researchers to platforms such as Facebook, YouTube, and Instagram is limited and virtually non-existent for SnapChat, WhatsApp, and WeChat. Cross-platform content comparisons are an important ingredient for a rich understand of the social media environment and these social media companies must better open their platforms to research in the public interest.

Finding 1: Misinformation about COVID-19 is circulated more on Twitter as compared to traditional media.

We find large differences between the quality of information shared about COVID-19 on traditional news and Twitter. Figure 1 shows the percentage of COVID-19 related content that contains information linked to a particular theme. The plot reports the prevalence of information on both social and news media for: 1) three specific pieces of misinformation; 2) a general set of content that describes the pandemic itself as a conspiracy or a hoax; and 3) advice about hygiene and social distancing during the pandemic. We differentiate content that shared misinformation (red in the plot) from content that debunked misinformation (green in the plot).

There are large differences between the levels of misinformation on Twitter and news media. Misinformation was comparatively more common on Twitter across all four categories, while debunking was relatively more common in traditional news. Meanwhile, advice on hygiene and social distancing appeared much more frequently in news media. Note that higher percentages are to be expected for longer format news articles since we rely on keyword searches for identification. This makes the misinformation findings even starker – despite much higher average word counts, far fewer news articles propagate misinformation.

Finding 2: There is a strong association between social media exposure and misperceptions about COVID-19. The inverse is true for exposure to traditional news.

Among our survey respondents we find a corresponding strong association between social media exposure and misperceptions about COVID-19. These results are plotted in Figure 2, with controls included for both socioeconomic characteristics and demographics. Moving from no social media exposure to its maximum is expected to increase one’s misperceptions of COVID-19 by 0.22 on the 0-1 scale and decreased self-reported social distancing compliance by 0.12 on that same scale.

This result stands in stark contrast with the observed relationship between traditional news exposure and our outcome measures. Traditional news exposure is positively associated with correct perceptions regarding COVID-19. Moving from no news exposure to its highest level is expected to reduce misperceptions by 0.12 on the 0-1 scale and to increase social distancing compliance by 0.28 on that same scale. The effects are plotted in Figure 2. Social media usage appears to be correlated with COVID-19 misperceptions, suggesting these misperceptions are partially a result of misinformation on social media. The same cannot be said of traditional news exposure.

Finding 3: Misperceptions about the pandemic are associated with lower levels of risk perceptions and social distancing compliance.

COVID-19 misperceptions are also powerfully associated with lower levels of social distancing compliance. Moving from the lowest level of COVID-19 misperceptions to its maximum is associated with a reduction of one’s social distancing by 0.39 on the 0-1 scale. The previously observed relationship between social media exposure and misperceptions disappears, suggestive of a mediated relationship. That is, social media exposure increases misperceptions, which in turn reduces social distancing compliance. Misperceptions is also weakly associated with lower COVID-19 risk perceptions. Estimates from our models using COVID-19 concern as the outcome can be found in the left panel of Figure 3, while social distancing can be found in the right panel.

Finally, we also see that the relationship between misinformation and both social distancing compliance and COVID-19 concern hold when including controls for science literacy and a number of fundamental predispositions that are likely associated with both misperceptions and following the advice of scientific experts, such as anti-intellectualism, pseudoscientific beliefs, and left-right ideology. These estimates can similarly be found in Figure 3.

Canadian Twitter and news data were collected from March 26 th to April 6 th , 2020. We collected all English-language tweets from a set of 620,000 users that have been determined to be likely Canadians. For inclusion, a given user must self-identify as Canadian-based, follow a large number of Canadian political elite accounts, or frequently use Canadian-specific hashtags. News media was collected from nineteen prominent Canadian news sites with active RSS feeds. These tweets and news articles were searched for “covid” or “coronavirus”, leaving a sample of 2.25 million tweets and 8,857 news articles.

Of the COVID-19 related content, we searched for terms associated with four instances of misinformation that circulated during the COVID-19 pandemic: that COVID-19 was no more serious than the flu, that vitamin C or other supplements will prevent contraction of the virus, that the initial animal-to-human transfer of the virus was the direct result of eating bats, or that COVID-19 was a hoax or conspiracy. Given that we used keyword searches to identify content, we manually reviewed a random sample of 500 tweets from each instance of misinformation. Each tweet was coded as one of four categories: propagating misinformation, combatting misinformation, content with the relevant keywords but unrelated to misinformation, or content that refers to the misinformation but does not offer comment.

We then calculated the overall level of misinformation for that instance on Twitter by multiplying the overall volume of tweets by the proportion of hand-coded content where misinformation was identified. Each news article that included relevant keywords was similarly coded. The volume of the news mentioning these terms was sufficiently low that all news articles were hand coded. To identify health recommendations, we used a similar keyword search for terms associated with particular recommendations: 1) social distancing including staying at home, staying at least 6 feet or 2 meters away and avoiding gatherings; and 2) washing hands and not touching any part of your face. 1 Further details on the media collection strategy and hand-coding schema are available in the supporting materials.

For survey data, we used a sample of nearly 2,500 Canadian citizens 18 years or older drawn from a probability-based online national panel fielded from April 2-6, 2020. Quotas we set on age, gender, region, and language to ensure sample representativeness, and data was further weighted within region by gender and age based on the 2016 Canadian census.

We measure levels of COVID-19 misperceptions by asking respondents to rate the truthfulness of a series of nine false claims, such as the coronavirus being no worse than the seasonal flu or that it can be warded off with Vitamin C. Each was asked on a scale from definitely false (0) to definitely true (5). We use Cronbach’s Alpha as an indicator of scale reliability. Cronbach’s Alpha ranges from 0-1, with scores above 0.8 indicating the reliability is “good.” These items score 0.88, so we can safely construct a 0-1 scale of misperceptions from them.

We evaluate COVID-19 risk perceptions with a pair of questions asking respondents how serious of a threat they believe the pandemic to be for themselves and for Canadians, respectively. Each question was asked on a scale from not at all (0) to very (4). We construct a continuous index with these items.

We quantify social distancing by asking respondents to indicate which of a series of behaviours they had undertaken in response to the pandemic, such as working from home or avoiding in-person contact with friends, family, and acquaintances. We use principal component analysis (PCA) to reduce the number of dimensions in these data while minimizing information loss. The analysis revealed 2 distinct dimensions in our questions. One dimension includes factors strongly determined by occupation, such as working from home and switching to online meetings. The other dimension contains more inclusive behaviours such as avoiding contact, travel, and crowded places. We generate predictions from the PCA for this latter dimension to use in our analyses. The factor loadings can be found in Table A1 of the supporting materials.

We gauge news and social media consumption by asking respondents to identify news outlets and social media platforms they have used over the past week for political news. The list of news outlets included 17 organizations such as mainstream sources like CBC and Global, and partisan outlets like Rebel Media and National Observer. The list of social media platforms included 10 options such as Facebook, Twitter, YouTube, and Instagram. We sum the total number of outlets/platforms respondents report using and take the log to adjust for extreme values. We measure offline political discussion with an index based on questions asking how often respondents have discussed politics with family, friends, and acquaintances over the past week. Descriptions of our primary variables can be found in Table A2 of the supporting materials.

We evaluate our hypotheses using a standard design that evaluates the association between our explanatory and outcome variables controlling for other observable factors we measured. In practice, randomly assigning social media exposure is impractical, while randomly assigning misinformation is unethical. This approach allows us to describe these relationships, though we cannot make definite claims to causality.

We hypothesize that social media exposure is associated with misinformation on COVID-19. Figure 2 presents the coefficients of models predicting the effects of news exposure, social media exposure, and political discussion on COVID-19 misinformation, risk perceptions, and social distancing. Socio-economic and demographic control estimates are not displayed. Full estimation results can be found in the Table A3 of the supporting materials.

We further hypothesize that COVID-19 misinformation is associated with lower COVID-19 risk perceptions and less social distancing compliance. Figure 3 presents the coefficients for models predicting the effects of misinformation, news exposure, and social media exposure on severity perceptions and social distancing. We show models with and without controls for science literacy and other predispositions. Full estimation results can be found in the Table A4 of the supporting materials.

Limitations and robustness

A study such as this comes with clear limitations. First, we have evaluated information coming from only a section of the overall media ecosystem and during a specific time-period. The level of misinformation differs across platforms and online news sites and a more granular investigation into these dynamics would be valuable. Our analysis suggests that similar dynamics exist across social media platforms, however. In the supplementary materials we show that associations between misperceptions and social media usage are even higher for other social media platforms, suggesting that our analysis of Twitter content may underrepresent the prevalence of misinformation on social media writ large. As noted above, existing limitations on data access make such cross-platform research difficult.

Second, our data is drawn from a single country and language case study and other countries may have different media environments and levels of misinformation circulating on social media. We anticipate the underlying dynamics found in this paper to hold across these contexts, however. Those who consume information from platforms where misinformation is more prevalent will have greater misperceptions and that these misperceptions will be linked to lower compliance with social distancing and lower risk perceptions. Third, an ecological problem is present wherein we do not link survey respondents directly to their social media consumption (and evaluation of the misinformation they are exposed to) and lack the ability to randomly assign social media exposure to make a strong causal argument. We cannot and do not make a causal argument here but argue instead that there is strong evidence for a misinformation to misperceptions to lower social distancing compliance link.

Students’ Essays on Infectious Disease Prevention, COVID-19 Published Nationwide

As part of the BIO 173: Global Change and Infectious Disease course, Professor Fred Cohan assigns students to write an essay persuading others to prevent future and mitigate present infectious diseases. If students submit their essay to a news outlet—and it’s published—Cohan awards them with extra credit.

As a result of this assignment, more than 25 students have had their work published in newspapers across the United States. Many of these essays cite and applaud the University’s Keep Wes Safe campaign and its COVID-19 testing protocols.

Cohan, professor of biology and Huffington Foundation Professor in the College of the Environment (COE), began teaching the Global Change and Infectious Disease course in 2009, when the COE was established. “I wanted very much to contribute a course to what I saw as a real game-changer in Wesleyan’s interest in the environment. The course is about all the ways that human demands on the environment have brought us infectious diseases, over past millennia and in the present, and why our environmental disturbances will continue to bring us infections into the future.”

Over the years, Cohan learned that he can sustainably teach about 170 students every year without running out of interested students. This fall, he had 207. Although he didn’t change the overall structure of his course to accommodate COVID-19 topics, he did add material on the current pandemic to various sections of the course.

“I wouldn’t say that the population of the class increased tremendously as a result of COVID-19, but I think the enthusiasm of the students for the material has increased substantially,” he said.

To accommodate online learning, Cohan shaved off 15 minutes from his normal 80-minute lectures to allow for discussion sections, led by Cohan and teaching assistants. “While the lectures mostly dealt with biology, the discussions focused on how changes in behavior and policy can solve the infectious disease problems brought by human disturbance of the environment,” he said.

Based on student responses to an introspective exam question, Cohan learned that many students enjoyed a new hope that we could each contribute to fighting infectious disease. “They discovered that the solution to infectious disease is not entirely a waiting game for the right technologies to come along,” he said. “Many enjoyed learning about fighting infectious disease from a moral and social perspective. And especially, the students enjoyed learning about the ‘socialism of the microbe,’ how preventing and curing others’ infections will prevent others’ infections from becoming our own. The students enjoyed seeing how this idea can drive both domestic and international health policies.”

A sampling of the published student essays are below:

Alexander Giummo ’22 and Mike Dunderdale’s ’23 op-ed titled “ A National Testing Proposal: Let’s Fight Back Against COVID-19 ” was published in the Journal Inquirer in Manchester, Conn.

They wrote: “With an expansive and increased testing plan for U.S. citizens, those who are COVID-positive could limit the number of contacts they have, and this would also help to enable more effective contact tracing. Testing could also allow for the return of some ‘normal’ events, such as small social gatherings, sports, and in-person class and work schedules.

“We propose a national testing strategy in line with the one that has kept Wesleyan students safe this year. The plan would require a strong push by the federal government to fund the initiative, but it is vital to successful containment of the virus.

“Twice a week, all people living in the U.S. should report to a local testing site staffed with professionals where the anterior nasal swab Polymerase Chain Reaction (PCR) test, used by Wesleyan and supported by the Broad Institute, would be implemented.”

Kalyani Mohan ’22 and Kalli Jackson ’22 penned an essay titled “ Where Public Health Meets Politics: COVID-19 in the United States ,” which was published in Wesleyan’s Arcadia Political Review .

They wrote: “While the U.S. would certainly benefit from a strengthened pandemic response team and structural changes to public health systems, that alone isn’t enough, as American society is immensely stratified, socially and culturally. The politicization of the COVID-19 pandemic shows that individualism, libertarianism and capitalism are deeply ingrained in American culture, to the extent that Americans often blind to the fact community welfare can be equivalent to personal welfare. Pandemics are multifaceted, and preventing them requires not just a cultural shift but an emotional one amongst the American people, one guided by empathy—towards other people, different communities and the planet. Politics should be a tool, not a weapon against its people.”

Sydnee Goyer ’21 and Marcel Thompson’s ’22 essay “ This Flu Season Will Be Decisive in the Fight Against COVID-19 ” also was published in Arcadia Political Review .

“With winter approaching all around the Northern Hemisphere, people are preparing for what has already been named a “twindemic,” meaning the joint threat of the coronavirus and the seasonal flu,” they wrote. “While it is known that seasonal vaccinations reduce the risk of getting the flu by up to 60% and also reduce the severity of the illness after the contamination, additional research has been conducted in order to know whether or not flu shots could reduce the risk of people getting COVID-19. In addition to the flu shot, it is essential that people remain vigilant in maintaining proper social distancing, washing your hands thoroughly, and continuing to wear masks in public spaces.”

An op-ed titled “ The Pandemic Has Shown Us How Workplace Culture Needs to Change ,” written by Adam Hickey ’22 and George Fuss ’21, was published in Park City, Utah’s The Park Record .

They wrote: “One review of academic surveys (most of which were conducted in the United States) conducted in 2019 found that between 35% and 97% of respondents in those surveys reported having attended work while they were ill, often because of workplace culture or policy which generated pressure to do so. Choosing to ignore sickness and return to the workplace while one is ill puts colleagues at risk, regardless of the perceived severity of your own illness; COVID-19 is an overbearing reminder that a disease that may cause mild, even cold-like symptoms for some can still carry fatal consequences for others.

“A mandatory paid sick leave policy for every worker, ideally across the globe, would allow essential workers to return to work when necessary while still providing enough wiggle room for economically impoverished employees to take time off without going broke if they believe they’ve contracted an illness so as not to infect the rest of their workplace and the public at large.”

Women’s cross country team members and classmates Jane Hollander ’23 and Sara Greene ’23 wrote a sports-themed essay titled “ This Season, High School Winter Sports Aren’t Worth the Risk ,” which was published in Tap into Scotch Plains/Fanwood , based in Scotch Plains, N.J. Their essay focused on the risks high school sports pose on student-athletes, their families, and the greater community.

“We don’t propose cutting off sports entirely— rather, we need to be realistic about the levels at which athletes should be participating. There are ways to make practices safer,” they wrote. “At [Wesleyan], we began the season in ‘cohorts,’ so the amount of people exposed to one another would be smaller. For non-contact sports, social distancing can be easily implemented, and for others, teams can focus on drills, strength and conditioning workouts, and skill-building exercises. Racing sports such as swim and track can compete virtually, comparing times with other schools, and team sports can focus their competition on intra-team scrimmages. These changes can allow for the continuation of a sense of normalcy and team camaraderie without the exposure to students from different geographic areas in confined, indoor spaces.”

Brook Guiffre ’23 and Maddie Clarke’s ’22 op-ed titled “ On the Pandemic ” was published in Hometown Weekly, based in Medfield, Mass.

“The first case of COVID-19 in the United States was recorded on January 20th, 2020. For the next month and a half, the U.S. continued operating normally, while many other countries began their lockdown,” they wrote. “One month later, on February 29th, 2020, the federal government approved a national testing program, but it was too little too late. The U.S. was already in pandemic mode, and completely unprepared. Frontline workers lacked access to N-95 masks, infected patients struggled to get tested, and national leaders informed the public that COVID-19 was nothing more than the common flu. Ultimately, this unpreparedness led to thousands of avoidable deaths and long-term changes to daily life. With the risk of novel infectious diseases emerging in the future being high, it is imperative that the U.S. learn from its failure and better prepare for future pandemics now. By strengthening our public health response and re-establishing government organizations specialized in disease control, we have the ability to prevent more years spent masked and six feet apart.”

In addition, their other essay, “ On Mass Extinction ,” was also published by Hometown Weekly .

“The sixth mass extinction—which scientists have coined as the Holocene Extinction—is upon us. According to the United Nations, around one million plant and animal species are currently in danger of extinction, and many more within the next decade. While other extinctions have occurred in Earth’s history, none have occurred at such a rapid rate,” they wrote. “For the sake of both biodiversity and infectious diseases, it is in our best interest to stop pushing this Holocene Extinction further.”

An essay titled “ Learning from Our Mistakes: How to Protect Ourselves and Our Communities from Diseases ,” written by Nicole Veru ’21 and Zoe Darmon ’21, was published in My Hometown Bronxville, based in Bronxville, N.Y.

“We can protect ourselves and others from future infectious diseases by ensuring that we are vaccinated,” they wrote. “Vaccines have high levels of success if enough people get them. Due to vaccines, society is no longer ravaged by childhood diseases such as mumps, rubella, measles, and smallpox. We have been able to eradicate diseases through vaccines; smallpox, one of the world’s most consequential diseases, was eradicated from the world in the 1970s.

“In 2000, the U.S. was nearly free of measles, yet, due to hesitations by anti-vaxxers, there continues to be cases. From 2000–2015 there were over 18 measles outbreaks in the U.S. This is because unless a disease is completely eradicated, there will be a new generation susceptible.

“Although vaccines are not 100% effective at preventing infection, if we continue to get vaccinated, we protect ourselves and those around us. If enough people are vaccinated, societies can develop herd immunity. The amount of people vaccinated to obtain herd immunity depends on the disease, but if this fraction is obtained, the spread of disease is contained. Through herd immunity, we protect those who may not be able to get vaccinated, such as people who are immunocompromised and the tiny portion of people for whom the vaccine is not effective.”

Dhruvi Rana ’22 and Bryce Gillis ’22 co-authored an op-ed titled “ We Must Educate Those Who Remain Skeptical of the Dangers of COVID-19 ,” which was published in Rhode Island Central .

“As Rhode Island enters the winter season, temperatures are beginning to drop and many studies have demonstrated that colder weather and lower humidity are correlated with higher transmissibility of SARS-CoV-2, the virus that causes COVID-19,” they wrote. “By simply talking or breathing, we release respiratory droplets and aerosols (tiny fluid particles which could carry the coronavirus pathogen), which can remain in the air for minutes to hours.

“In order to establish herd immunity in the US, we must educate those who remain skeptical of the dangers of COVID-19. Whether community-driven or state-funded, educational campaigns are needed to ensure that everyone fully comprehends how severe COVID-19 is and the significance of airborne transmission. While we await a vaccine, it is necessary now more than ever that we social distance, avoid crowds, and wear masks, given that colder temperatures will likely yield increased transmission of the virus.”

Danielle Rinaldi ’21 and Verónica Matos Socorro ’21 published their op-ed titled “ Community Forum: How Mask-Wearing Demands a Cultural Reset ” in the Ewing Observer , based in Lawrence, N.J.

“In their own attempt to change personal behavior during the pandemic, Wesleyan University has mandated mask-wearing in almost every facet of campus life,” they wrote. “As members of our community, we must recognize that mask-wearing is something we are all responsible and accountable for, not only because it is a form of protection for us, but just as important for others as well. However, it seems as though both Covid fatigue and complacency are dominating the mindsets of Americans, leading to even more unwillingness to mask up. Ultimately, it is inevitable that this pandemic will not be the last in our lifespan due to global warming creating irreversible losses in biodiversity. As a result, it is imperative that we adopt the norm of mask-wearing now and undergo a culture shift of the abandonment of an individualistic mindset, and instead, create a society that prioritizes taking care of others for the benefit of all.”

Shayna Dollinger ’22 and Hayley Lipson ’21 wrote an essay titled “ My Pandemic Year in College Has Brought Pride and Purpose. ” Dollinger submitted the piece, rewritten in first person, to Jewish News of Northern California . Read more about Dollinger’s publication in this News @ Wesleyan article .

“I lay in the dead grass, a 6-by-6-foot square all to myself. I cheer for my best friend, who is on the stage constructed at the bottom of Foss hill, dancing with her Bollywood dance group. Masks cover their ordinarily smiling faces as their bodies move in sync. Looking around at friends and classmates, each in their own 6-by-6 world, I feel an overwhelming sense of normalcy.

“One of the ways in which Wesleyan has prevented outbreaks on campus is by holding safe, socially distanced events that students want to attend. By giving us places to be and things to do on the weekends, we are discouraged from breaking rules and causing outbreaks at ‘super-spreader’ events.”

An op-ed written by Luna Mac-Williams ’22 and Daëlle Coriolan ’24 titled “ Collectivist Practices to Combat COVID-19 ” was published in the Wesleyan Argus .

“We are embroiled in a global pandemic that disproportionately affects poor communities of color, and in the midst of a higher cultural consciousness of systemic inequities,” they wrote. “A cultural shift to center collectivist thought and action not only would prove helpful in disease prevention, but also belongs in conversation with the Black Lives Matter movement. Collectivist models of thinking effectively target the needs of vulnerable populations including the sick, the disenfranchised, the systematically marginalized. Collectivist systems provide care, decentering the capitalist, individualist system, and focusing on how communities can work to be self-sufficient and uplift our own neighbors.”

An essay written by Maria Noto ’21 , titled “ U.S. Individualism Has Deadly Consequences ,” is published in the Oneonta Daily Star , based in Oneonta, N.Y.

She wrote, “When analyzing the cultures of certain East Asian countries, several differences stand out. For instance, when people are sick and during the cold and flu season, many East Asian cultures, including South Korea, use mask-wearing. What is considered a threat to freedom by some Americans is a preventive action and community obligation in this example. This, along with many other cultural differences, is insightful in understanding their ability to contain the virus.

“These differences are deeply seeded in the values of a culture. However, there is hope for the U.S. and other individualistic cultures in recognizing and adopting these community-centered approaches. Our mindset needs to be revolutionized with the help of federal and local assistance: mandating masks, passing another stimulus package, contact tracing, etc… However, these measures will be unsuccessful unless everyone participates for the good of a community.”

March 3, 2022

As we reach the two-year mark of the initial wave of pandemic-induced school shutdowns, academic normalcy remains out of reach for many students, educators, and parents. In addition to surging COVID-19 cases at the end of 2021, schools have faced severe staff shortages , high rates of absenteeism and quarantines , and rolling school closures . Furthermore, students and educators continue to struggle with mental health challenges , higher rates of violence and misbehavior , and concerns about lost instructional time .

As we outline in our new research study released in January, the cumulative impact of the COVID-19 pandemic on students’ academic achievement has been large. We tracked changes in math and reading test scores across the first two years of the pandemic using data from 5.4 million U.S. students in grades 3-8. We focused on test scores from immediately before the pandemic (fall 2019), following the initial onset (fall 2020), and more than one year into pandemic disruptions (fall 2021).

Average fall 2021 math test scores in grades 3-8 were 0.20-0.27 standard deviations (SDs) lower relative to same-grade peers in fall 2019, while reading test scores were 0.09-0.18 SDs lower. This is a sizable drop. For context, the math drops are significantly larger than estimated impacts from other large-scale school disruptions, such as after Hurricane Katrina—math scores dropped 0.17 SDs in one year for New Orleans evacuees .

Even more concerning, test-score gaps between students in low-poverty and high-poverty elementary schools grew by approximately 20% in math (corresponding to 0.20 SDs) and 15% in reading (0.13 SDs), primarily during the 2020-21 school year. Further, achievement tended to drop more between fall 2020 and 2021 than between fall 2019 and 2020 (both overall and differentially by school poverty), indicating that disruptions to learning have continued to negatively impact students well past the initial hits following the spring 2020 school closures.

These numbers are alarming and potentially demoralizing, especially given the heroic efforts of students to learn and educators to teach in incredibly trying times. From our perspective, these test-score drops in no way indicate that these students represent a “ lost generation ” or that we should give up hope. Most of us have never lived through a pandemic, and there is so much we don’t know about students’ capacity for resiliency in these circumstances and what a timeline for recovery will look like. Nor are we suggesting that teachers are somehow at fault given the achievement drops that occurred between 2020 and 2021; rather, educators had difficult jobs before the pandemic, and now are contending with huge new challenges, many outside their control.

Clearly, however, there’s work to do. School districts and states are currently making important decisions about which interventions and strategies to implement to mitigate the learning declines during the last two years. Elementary and Secondary School Emergency Relief (ESSER) investments from the American Rescue Plan provided nearly $200 billion to public schools to spend on COVID-19-related needs. Of that sum, $22 billion is dedicated specifically to addressing learning loss using “evidence-based interventions” focused on the “ disproportionate impact of COVID-19 on underrepresented student subgroups. ” Reviews of district and state spending plans (see Future Ed , EduRecoveryHub , and RAND’s American School District Panel for more details) indicate that districts are spending their ESSER dollars designated for academic recovery on a wide variety of strategies, with summer learning, tutoring, after-school programs, and extended school-day and school-year initiatives rising to the top.

Comparing the negative impacts from learning disruptions to the positive impacts from interventions

To help contextualize the magnitude of the impacts of COVID-19, we situate test-score drops during the pandemic relative to the test-score gains associated with common interventions being employed by districts as part of pandemic recovery efforts. If we assume that such interventions will continue to be as successful in a COVID-19 school environment, can we expect that these strategies will be effective enough to help students catch up? To answer this question, we draw from recent reviews of research on high-dosage tutoring , summer learning programs , reductions in class size , and extending the school day (specifically for literacy instruction) . We report effect sizes for each intervention specific to a grade span and subject wherever possible (e.g., tutoring has been found to have larger effects in elementary math than in reading).

Figure 1 shows the standardized drops in math test scores between students testing in fall 2019 and fall 2021 (separately by elementary and middle school grades) relative to the average effect size of various educational interventions. The average effect size for math tutoring matches or exceeds the average COVID-19 score drop in math. Research on tutoring indicates that it often works best in younger grades, and when provided by a teacher rather than, say, a parent. Further, some of the tutoring programs that produce the biggest effects can be quite intensive (and likely expensive), including having full-time tutors supporting all students (not just those needing remediation) in one-on-one settings during the school day. Meanwhile, the average effect of reducing class size is negative but not significant, with high variability in the impact across different studies. Summer programs in math have been found to be effective (average effect size of .10 SDs), though these programs in isolation likely would not eliminate the COVID-19 test-score drops.

Figure 1: Math COVID-19 test-score drops compared to the effect sizes of various educational interventions

$Figure 1 – Math COVID-19 test-score drops compared to the effect sizes of various educational interventions$

Source: COVID-19 score drops are pulled from Kuhfeld et al. (2022) Table 5; reduction-in-class-size results are from pg. 10 of Figles et al. (2018) Table 2; summer program results are pulled from Lynch et al (2021) Table 2; and tutoring estimates are pulled from Nictow et al (2020) Table 3B. Ninety-five percent confidence intervals are shown with vertical lines on each bar.

Notes: Kuhfeld et al. and Nictow et al. reported effect sizes separately by grade span; Figles et al. and Lynch et al. report an overall effect size across elementary and middle grades. We were unable to find a rigorous study that reported effect sizes for extending the school day/year on math performance. Nictow et al. and Kraft & Falken (2021) also note large variations in tutoring effects depending on the type of tutor, with larger effects for teacher and paraprofessional tutoring programs than for nonprofessional and parent tutoring. Class-size reductions included in the Figles meta-analysis ranged from a minimum of one to minimum of eight students per class.

Figure 2 displays a similar comparison using effect sizes from reading interventions. The average effect of tutoring programs on reading achievement is larger than the effects found for the other interventions, though summer reading programs and class size reduction both produced average effect sizes in the ballpark of the COVID-19 reading score drops.

Figure 2: Reading COVID-19 test-score drops compared to the effect sizes of various educational interventions

Source: COVID-19 score drops are pulled from Kuhfeld et al. (2022) Table 5; extended-school-day results are from Figlio et al. (2018) Table 2; reduction-in-class-size results are from pg. 10 of Figles et al. (2018) ; summer program results are pulled from Kim & Quinn (2013) Table 3; and tutoring estimates are pulled from Nictow et al (2020) Table 3B. Ninety-five percent confidence intervals are shown with vertical lines on each bar.

Notes: While Kuhfeld et al. and Nictow et al. reported effect sizes separately by grade span, Figlio et al. and Kim & Quinn report an overall effect size across elementary and middle grades. Class-size reductions included in the Figles meta-analysis ranged from a minimum of one to minimum of eight students per class.

There are some limitations of drawing on research conducted prior to the pandemic to understand our ability to address the COVID-19 test-score drops. First, these studies were conducted under conditions that are very different from what schools currently face, and it is an open question whether the effectiveness of these interventions during the pandemic will be as consistent as they were before the pandemic. Second, we have little evidence and guidance about the efficacy of these interventions at the unprecedented scale that they are now being considered. For example, many school districts are expanding summer learning programs, but school districts have struggled to find staff interested in teaching summer school to meet the increased demand. Finally, given the widening test-score gaps between low- and high-poverty schools, it’s uncertain whether these interventions can actually combat the range of new challenges educators are facing in order to narrow these gaps. That is, students could catch up overall, yet the pandemic might still have lasting, negative effects on educational equality in this country.

Given that the current initiatives are unlikely to be implemented consistently across (and sometimes within) districts, timely feedback on the effects of initiatives and any needed adjustments will be crucial to districts’ success. The Road to COVID Recovery project and the National Student Support Accelerator are two such large-scale evaluation studies that aim to produce this type of evidence while providing resources for districts to track and evaluate their own programming. Additionally, a growing number of resources have been produced with recommendations on how to best implement recovery programs, including scaling up tutoring , summer learning programs , and expanded learning time .

Ultimately, there is much work to be done, and the challenges for students, educators, and parents are considerable. But this may be a moment when decades of educational reform, intervention, and research pay off. Relying on what we have learned could show the way forward.

An unprecedented infodemic has been witnessed to create massive damage to human society. However, it was not thoroughly investigated. This systematic review aims to (1) synthesize the existing literature on the causes and impacts of COVID-19 infodemic; (2) summarize the proposed strategies to fight with COVID-19 infodemic; and (3) identify the directions for future research. A systematic literature search following the PRISMA guideline covering 12 scholarly databases was conducted to retrieve various types of peer-reviewed articles that reported causes, impacts, or countermeasures of the infodemic. Empirical studies were assessed for risk of bias using the Mixed-Methods Appraisal Tool. A coding theme was iteratively developed to categorize the causes, impacts, and countermeasures found from the included studies. Social media usage, low level of health/eHealth literacy, and fast publication process and preprint service are identified as the major causes of the infodemic. Besides, the vicious circle of human rumor-spreading behavior and the psychological issues from the public (e.g., anxiety, distress, fear) emerges as the characteristic of the infodemic. Comprehensive lists of countermeasures are summarized from different perspectives, among which risk communication and consumer health information need/seeking are of particular importance. Theoretical and practical implications are discussed and future research directions are suggested.

COVID-19 has heightened human suffering, undermined the economy, turned the lives of billions of people around the globe upside down, and significantly affected the health, economic, environmental and social domains. This study aims to provide a comprehensive analysis of the impact of the COVID-19 outbreak on the ecological domain, the energy sector, society and the economy and investigate the global preventive measures taken to reduce the transmission of COVID-19. This analysis unpacks the key responses to COVID-19, the efficacy of current initiatives, and summarises the lessons learnt as an update on the information available to authorities, business and industry. This review found that a 72-hour delay in the collection and disposal of waste from infected households and quarantine facilities is crucial to controlling the spread of the virus. Broad sector by sector plans for socio-economic growth as well as a robust entrepreneurship-friendly economy is needed for the business to be sustainable at the peak of the pandemic. The socio-economic crisis has reshaped investment in energy and affected the energy sector significantly with most investment activity facing disruption due to mobility restrictions. Delays in energy projects are expected to create uncertainty in the years ahead. This report will benefit governments, leaders, energy firms and customers in addressing a pandemic-like situation in the future.

1. Introduction

The newly identified infectious coronavirus (SARS-CoV-2) was discovered in Wuhan and has spread rapidly since December 2019 within China and to other countries around the globe ( Zhou et al., 2020 ; Kabir et al., 2020 ). The source of SARS-CoV-2 is still unclear ( Gorbalenya et al., 2020 ). Fig. 1 demonstrates the initial timeline of the development of SARS-CoV-2 ( Yan et al., 2020 ). The COVID-19 pandemic has posed significant challenges to global safety in public health ( Wang et al., 2020 ). On 31 st January 2020, the World Health Organization (WHO), due to growing fears about the rapid spread of coronavirus, announced a global epidemic and on 11 th March, the disease was recognised as a pandemic ( Chowdhury et al., 2021 ). COVID-19 clinical trials indicate that almost all patients admitted to hospital have trouble breathing and pneumonia-like symptoms ( Holshue et al., 2020 ). Clinical diagnosis has identified that COVID-19 (disease caused by SARS-CoV-2) patients have similar indications to other coronavirus affected patients, e.g. Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS) ( Wang and Su, 2020 ). The initial indication of a COVID-19 infection is coughing, fever, and short breath, and in the later stages, it can damage the kidney, cause pneumonia, and unexpected death ( Mofijur et al., 2020 ). The vulnerability of the elderly (>80 years of age) is high, with a fatality rate of ~22% of cases infected by COVID-19 ( Abdullah et al., 2020 ). The total number of confirmed COVID-19 cases has reached over 33 million as of 29 th September 2020, with more than 213 countries and regions affected by the pandemic ( Worldometer, 2020 ). Over 1,003,569 people have already passed away ( Worldometer, 2020 ) due to COVID-19. Most countries are currently trying to combat the virus spread by screening for COVID-19 in large numbers and maintaining social distancing policies with an emphasis on the health of human beings.

The initial stage development timeline for COVID-19 ( Yan et al., 2020 ).

Fig. 2 shows infections and replication cycle of the coronavirus. In extreme cases, the lungs are the most severely damaged organ of a SARS-CoV-2 infected person (host). The alveoli are porous cup-formed small cavities located in the structure of the lungs where the gas exchange of the breathing process take place. The most common cells on the alveoli are the type II cells.

It has been reported that travel restrictions play a significant role in controlling the initial spread of COVID-19 ( Chinazzi et al., 2020 ; Aldila et al., 2020 ; Beck and Hensher, 2020 ; Bruinen de Bruin et al., 2020 ; de Haas et al., 2020 ). It has been reported that staying at home is most useful in controlling both the initial and last phase of infectious diseases ( de Haas et al., 2020 ; Cohen, 2020 , Pirouz et al., 2020 ). However, since the start of the COVID-19 pandemic, quarantines, entry bans, as well as other limitations have been implemented for citizens in or recent travellers to several countries in the most affected areas ( Sohrabi et al., 2020 ). Also, most of the industries were shutdown to lower mobility. A potential benefit of these measures is the reduction of pollution by the industrial and transportation sector, improving urban sustainability ( Jiang et al., 2021 ). Fig. 3 shows the global responses to lower the impact of the COVID-19 outbreak. There have been negative economic and social implications due to restrictions and decreased travel readiness worldwide ( Leal Filho et al., 2020 ). A fall in the volume of business activity and international events and an increase in online measures could have a long-term impact. The status of global transport and air activity as a result of the COVID-19 pandemic is shown in Fig. 4 ( International Energy Agency (IEA), 2020 ). By March 2020, the average global road haulage activity in regions with lockdowns had declined to almost 50% of the 2019 standard. Air travel has almost completely stopped in certain regions with aviation activity decreasing by over 90% in some European countries. Air activity in China recovered slightly from a low in late February, with lockdown measures somewhat eased. Nevertheless, as lockdowns spread, by the end of Q1 2020, global aviation activity decreased by a staggering 60%.

Initial preventive measures to lower the COVID-19 outbreak ( Bruinen de Bruin et al., 2020 ).

Global transport and aviation activity in the first quarter of the year 2020 ( International Energy Agency (IEA), 2020 ).

The spread of COVID-19 continues to threaten the public health situation severely ( Chinazzi et al., 2020 ) and greatly affect the global economy. Labour displacement, business closures and stock crashes are just some of the impacts of this global lockdown during the pandemic. According to the International Monetary Fund (IMF), the effect of COVID-19 will result in a worldwide economic decline in 2020 and a decline in the economic growth to 3% ( International Monetary Fund (IMF) ). COVID-19 has a detrimental impact on economic growth due to two primary factors. In the beginning, the exponential growth of the global epidemic directly contributed to considerable confusion about instability in the financial and capital markets. Secondly, countries have strictly regulated human movement and transport to monitor the growth of the epidemic and significantly reduced economic activity, putting pressure on both consumer and productive economic activity.

Since the 1970s, the link between economic growth and pollution has been an important global concern. The assessment of energy and financial efficiency is usually connected to environmental pollution research. Green practices at a national level, the inclusion of renewable energy, regulatory pressure and the sustainable use of natural resources are associated with environmental sustainability ( Khan et al., 2020 ). One study has shown that environmental pollution increases with economic growth and vice versa ( Cai et al., 2020 ). The strict control over movement and business activity due to COVID-19 has led to an economic downturn, which is in turn, expected to reduce environmental pollution. This paper systematically assesses how the novel coronavirus has had a global effect on society, the energy sector and the environment. This study presents data compiled from the literature, news sources and reports (from February 2020 to July 2020) on the management steps implemented across the globe to control and reduce the impact of COVID-19. The study will offer guidelines for nations to assess the overall impact of COVID-19 in their countries.

2. Impact of COVID-19 on the environmental domain

2.1. waste generation.

The generation of different types of waste indirectly creates a number of environmental concerns ( Schanes et al., 2018 ). The home isolation and pop-up confinement services in countries that have experienced major impacts of COVID-19 are standard practise, as hospitals are given priority to the most serious cases. In some countries, hotels are being used to isolate travellers for at least two weeks on entry. In several countries, such quarantine measures have resulted in consumers increasing their domestic online shopping activity that has increased domestic waste. In addition, food bought online is packaged, so inorganic waste has also increased. Medical waste has also increased. For instance, Wuhan hospitals produced an average of 240 metric tonnes of medical waste during the outbreak compared to their previous average of fewer than 50 tonnes ( Zambrano-Monserrate et al., 2020 ). This unusual situation poses new and major obstacles in the implementation of waste collection services, thus creating a new challenge for waste collection and recycling groups. With the global adaptation to exponential behavioural and social shifts in the face of COVID-19 challenges, municipal services such as waste collection and management need to alter their operations to play an important role in reducing the spread of infectious diseases.

2.1.1. Lifespan of COVID-19 on different waste media

SARS-CoV-2′s transmission activity has major repercussions for waste services. SARS-CoV-2 attacks host cells with ACE2 proteins directly. ACE2 is a cell membrane-associated enzyme in the lungs, heart and kidneys. When all the resources in the host cell are infected and depleted, the viruses leave the cell in the so-called shedding cycle ( Nghiem et al., 2020 ). Clinical and virological evidence suggests that the elimination of the SARS-CoV-2 virus is most relevant early on, right before and within a couple of days of the onset of the illness ( AEMO, 2020 ). Fomites are known as major vectors for the replication of other infectious viruses during the outbreak ( Park et al., 2015 ). Evidence from SARS-CoV-2 and other coronaviruses show that they remain effective for up to a few days in the atmosphere and on a variety of surfaces ( Fig. 5 ). The survival time of SARS-CoV-2 on hard and plastic surfaces is up to three days indicating that waste materials from COVID-19 patients may contain coronavirus and be a source of infection spread ( Chin et al., 2020 ). During the early stages of this epidemic, updated waste disposal methods to tackle COVID-19 were not implemented on the broader community. The concept of clinical waste essentially also applies to waste from contaminated homes and quarantine facilities. Throughout this pandemic, huge volumes of domestic and hospital waste, particularly plastic waste, has been generated. This has already impeded current efforts to reduce plastic waste and decrease its disposal in the environment. More effort should be made to find alternatives to heavily used plastics.

2.1.2. Waste recycling service

COVID-19 has already had significant effects on waste recycling. Initially, as the outbreak spread and lockdowns were implemented in several countries, both public authorities and municipal waste management officials had to adjust to the situation quickly. Waste disposal has also been a major environmental problem for all technologically advanced nations, as no clear information was available about the retention time of SARS-CoV-2 ( Liu et al., 2020 ). Recycling is a growing and efficient means of pollution control, saving energy and conserving natural resources ( Ma et al., 2019 ). Recycling projects in various cities have been put on hold due to the pandemic, with officials worried about the possibility of COVID-19 spreading to recycling centres. Waste management has been limited in affected European countries. For example, Italy prohibited the sorting of waste by infected citizens. Extensive waste management during the pandemic is incredibly difficult because of the scattered nature of the cases and the individuals affected. The value of implementing best management practises for waste handling and hygiene to minimise employee exposure to potentially hazardous waste, should be highlighted at this time. Considering the possible role of the environment in the spread of SARS-CoV-2 ( Qu et al., 2020 ), the processing of both household and quarantine facility waste is a crucial point of control. Association of Cities and Regions for sustainable Resource management (ACR+) has reported on the provision of separate collection services to COVID-19 contaminated households and quarantine facilities to protect frontline waste workers in Europe, as shown in Fig. 6 . ACR+ also suggests a 72-hour delay in waste disposal (the possible lifespan of COVID-19 in the environment) ( Nghiem et al., 2020 ). Moreover, the collected waste should be immediately transported to waste incinerators or sites without segregation.

Recommended waste management during COVID-19 ( ACR+ 2020 ).

2.2. NO 2 emissions

Without the global pandemic, we had naively anticipated that in 2020 global emissions would rise by around 1% on a five-year basis. Instead, the sharp decline in economic activity in response to the current crisis will most probably lead to a modest drop in global greenhouse emissions. The European Space Agency (ESA), with its head office in Paris, France, is an intergovernmental body made up of 22 European countries committed to exploring the international space. To monitor air pollution in the atmosphere, the ESA uses the Copernicus Sentinel-5P Satellite. In addition to the compound contents measurement, the Copernicus Sentinel-5P troposphere monitor (TROPOMI) and other specified precision equipment measure ozone content, sulphur dioxide, carbon monoxide, and methane. Table 1 shows NO 2 emissions data acquisition by ESA using Sentinel-5P across different regions of Europe ( Financial Times, 2020 ).

NO 2 emissions data acquisition by ESA using Sentinel-5P across different regions of Europe ( Financial Times, 2020 ).

Burning fossil fuels, such as coal, oil, gas and other fuels, is the source of atmospheric nitrogen dioxide ( Munawer, 2018 ). The bulk of the NO 2 in cities, however, comes from emissions from motor vehicles (approximately 80%). Other NO 2 sources include petroleum and metal refining, coal-fired electricity, other manufacturing and food processing industries. Some NO 2 is naturally produced by lightning in the atmosphere and from the soil, water, and plants, which, taken together, constitutes not even 1% of the total NO 2 found in the air of our localities. Due to pollution variations as well as changes in weather conditions, the levels of the NO 2 in our atmosphere differ widely every day. Anthropogenic pollution is estimated to contain around 53 million tonnes of NO 2 annually. Nitrogen dioxide, together with nitrogen oxide (NO), are considered the major components of oxides of nitrogen (NOx) ( M Palash et al., 2013 ; Fattah et al., 2013 ). NO, and NO 2 are susceptible to other chemicals and form acid rain that is toxic to the environment ( Mofijur et al., 2013 ; Ashraful et al., 2014 ), WHO lists NO 2 as one of the six typical air contaminants in the atmosphere. For this reason, the amount of NO 2 in the atmosphere is used as a precise measure for determining whether the COVID-19 outbreak affects environmental pollution.

NO 2 is an irritating reddish-brown gas with an unpleasant smell, and when cooled or compressed, it becomes a yellowish-brown liquid ( Wang and Su, 2020 ). NO 2 inflames the lung linings and can decrease lung infection immunity. High levels of NO 2 in the air we breathe can corrode our body's lung tissues . Nitrogen dioxide is a problematic air pollutant because it leads to brown photochemical smog formation, which can have significant impacts on human health ( Huang et al., 2020 ). Brief exposure to high concentrations of NO 2 can lead to respiratory symptoms such as coughing, wheezing, bronchitis, flu, etc., and aggravate respiratory illnesses such as asthma. Increased NO 2 levels can have major effects on individuals with asthma, sometimes leading to frequent and intense attacks ( Munawer, 2018 ). Asthmatic children and older individuals with cardiac illness are most vulnerable in this regard. However, its main drawback is that it produces two of the most harmful air pollutants, ozone and airborne particles. Ozone gas affects our lungs and the crops we eat.

2.2.1. NO₂ emissions across different countries

According to the ESA ( European Space Agency (ESA), 2020 ), average levels of NO 2 declined by 40% between 13 th March 2020 to 13 th April 2020. The reduction was 55% compared to the same period in 2019. Fig. 7 compares the 2019-2020 NO 2 concentration ( European Space Agency (ESA), 2020 ). The displayed satellite image was captured with the TROPOMI by ESA satellite Sentinel-5P. The percentage reductions in average NO 2 emissions in European countries during the COVID-19 outbreak from 1 st April to 30 th April 2020 can be seen in Fig. 8 ( Myllyvirta, 2020 ). Portugal, Spain, Norway, Croatia, France, Italy, and Finland are the countries that experienced the largest decrease in NO 2 levels, with 58%, 48%, 47%, 43% and 41%, respectively.

Comparison of the NO 2 concentration between 2019 and 2020 in Europe ( European Space Agency (ESA), 2020 ).

Changes in average NO 2 emission in different countries ( Myllyvirta, 2020 ).

The average 10-day animation of NO 2 emissions throughout Europe (from 1 st January to 11 th March 2020), demonstrated the environmental impact of Italy's economic downturn, see Fig. 9 ( European Space Agency (ESA), 2020 ). In the recent four weeks (Last week of February 2020 to the third week of March 2020) the average concentration of NO 2 in Milan, Italy, has been at least 24% less than the previous four weeks. In the week of 16 – 22 March, the average concentration was 21% lower than in 2019 for the same week. Over the last four weeks of January 2020, NO 2 emissions in Bergamo city has been gradually declining. During the week of 16–22 March, the average concentration was 47% less than in 2019. In Rome, NO 2 rates were 26–35% lower than average in the last four weeks (third week of January 2020 to the third week of February 2020) than they were during the same week of 2019 ( Atmosphere Monitoring Service, 2020 ).

Fig. 10 shows a comparison of NO 2 volumes in Spain in March 2019 and 2020. As per ( European Space Agency (ESA), 2020 ), Spain's NO 2 pollutants decreased by up to 20–30% due to lockdown, particularly across big cities like Madrid, Barcelona, and Seville. ESA Sentinel-5P captured the satellite image using TROPOMI. Satellite images of the 10 days between 14 th and 25 th March 2020 show that NO 2 tropospheric concentration in the areas of Madrid, Barcelona, Valencia, and Murcia ranges from 0–90 mg/m 3 . The NO 2 tropospheric concentration for Seville is almost 0 mg/m 3 for the same time. For March 2019, the average NO 2 tropospheric concentration for the Madrid area was between 90 and 160 mg/m 3 . At the same time, the range of NO 2 tropospheric concentration for Barcelona, Valencia, and Seville area was between 90–140 mg/m 3 , 90-130 mg/m 3 , and 30–50 mg/m 3 , respectively.

Fig. 11 shows the reduction in the amount of NO 2 emissions in France in March 2019 and 2020 ( European Space Agency (ESA), 2020 ). In France, levels of NO 2 have been reduced by 20% to 30%. The ESA Sentinel-5P satellite image was captured with the TROPOMI. In Paris and other major cities, the emission levels of NO 2 considerably lowered due to lockdown. The three major areas of France where NO 2 tropospheric concentration was significant are Paris, Lyon, Marseille and their surroundings. Satellite images of the ten days between 14 th and 25 th March 2020 show that NO 2 tropospheric concentration of the Paris, Lyon, Marseille areas ranges 30–90 mg/m 3 , 20–40 mg/m 3 and 40–80 mg/m 3 , respectively. For March 2019, the average NO 2 tropospheric concentration for the same areas was reported as 100–160 mg/m 3 , 30–60 mg/m 3, and 90–140 mg/m 3 , respectively.

Various industries across the UK have been affected by COVID-19, which has influenced air contamination. As shown in Fig. 12 , there were notable drops in the country's NO 2 emissions on the first day of quarantine ( Khoo, 2020 ). Edinburgh showed the most significant reduction. The average NO 2 emissions on 26 th March 2020, were 28 μg/m 3 while on the same day of 2019, this was 74 μg/m 3 ( Khoo, 2020 ). The second biggest reduction was observed in London Westminster where emissions reduced from 58 µg/m 3 to 30 µg/m 3 . Not all cities have seen such a significant decrease, with daily air pollution reducing by 7 μg/m 3 compared to the previous year in Manchester Piccadilly, for example ( Statista, 2020 ).

2.3. PM emission

The term particulate matter, referred to as PM, is used to identify tiny airborne particles. PM forms in the atmosphere when pollutants chemically react with each other. Particles include pollution, dirt, soot, smoke, and droplets. Pollutants emitted from vehicles, factories, building sites, tilled areas, unpaved roads and the burning of fossil fuels also contribute to PM in the air ( Baensch-Baltruschat et al., 2020 ). Grilling food (by burning leaves or gas grills), smoking cigarettes, and burning wood on a fireplace or stove also contribute to PM. The aerodynamic diameter is considered a simple way to describe PM's particle size as these particles occur in various shapes and densities. Particulates are usually divided into two categories, namely, PM 10 that are inhalable particles with a diameter of 10 μm or less and PM 2.5 which are fine inhalable particle with a diameter of 2.5 μm or less. PM 2.5 exposure causes relatively severe health problems such as non-fatal heart attacks, heartbeat irregularity, increased asthma, reduced lung function, heightened respiratory symptoms, and premature death ( Weitekamp et al., 2020 ).

PM 2.5 also poses a threat to the environment, including lower visibility (haze) in many parts of the globe. Particulates can be transported long distances then settle on the ground or in water sources. In these contexts and as a function of the chemical composition, PM 2.5 may cause acidity in lakes and stream water, alter the nutrient balance in coastal waters and basins, deplete soil nutrients and damage crops on farms, affect the biodiversity in the ecosystem, and contribute to acid rain. This settling of PM, together with acid rain, can also stain and destroy stones and other materials such as statues and monuments, which include valuable cultural artefacts ( Awad et al., 2020 ).

2.3.1. PM emission in different countries

Due to the COVID-19 outbreak, PM emission in most countries has been reduced ( Chatterjee et al., 2020 ; Ghahremanloo et al., 2021 ; Gualtieri et al., 2020 ; Sharifi and Khavarian-Garmsir, 2020 ; Srivastava, 2020 ). Fig. 13 shows the impact of COVID19 on PM emission in a number of some countries around the world ( Myllyvirta, 2020 ). The largest reductions in PM pollution took place in Portugal, with 55%, followed by Norway, Sweden, and Poland with reductions of 32%, 30%, and 28%, respectively. Spain, Poland, and Finland recorded PM emission reductions of 19%, 17% and 16%, respectively. Both Romania and Croatia recorded no changes in PM level, with Switzerland and Hungary recording about a 3% increase in PM emission.

Reduction of PM emission in different countries ( Myllyvirta, 2020 ).

PM emissions have been significantly reduced during the epidemic in most regions of Italy. Fig. 14 illustrates the changes in COVID-19 containment emissions before and after a lockdown in major cities in Italy. According to a recent study by Sicard et al. ( Sicard et al., 2020 ), lockdown interventions have had a greater effect on PM emission. They found that confinement measures reduce PM 10 emissions in all major cities by “around 30% to 53%” and “around 35% to 56%”.

2.4. Noise emission

Noise is characterised as an undesirable sound that may be produced from different activities, e.g. transit by engine vehicles and high volume music. Noise can cause health problems and alter the natural condition of ecosystems. It is among the most significant sources of disruption in people and the environment ( Zambrano-Monserrate and Ruano, 2019 ). The European Environment Agency (EEA) states that traffic noise is a serious environmental problem that negatively affects the health and security of millions of citizens in Europe. The consequences of long-term exposure to noise include sleep disorders, adverse effects on the heart and metabolic systems, and cognitive impairment in children. The EEA estimates that noise pollution contributes to 48,000 new cases of heart disease and 12,000 early deaths per year. They also reported chronic high irritation for 22 million people and a chronic high level of sleep disorder for 6.5 million people ( Lillywhite, 2020 ).

Most governments have imposed quarantine measures that require people to spend much more time at home. This has considerably reduced the use of private and public transport. Commercial activities have almost completely stopped. In most cities in the world, these changes have caused a significant decline in noise levels. This was followed by a significant decline in pollution from contaminants and greenhouse gas emissions. Noise pollution from sources like road, rail or air transport has been linked to economic activity. Consequently, we anticipate that the levels of transport noise will decrease significantly due to the decreased demand for mobility in the short term ( Ro, 2020 ).

For example, it was obvious that environmental noise in Italy was reduced after 8 th March 2020 (the lockdown start date) due to a halt in commercial and recreational activities. A seismograph facility in Lombardy city in Italy that was severely affected by the COVID-19 pandemic indicated how the quarantine measures reduce both traffic and noise emissions. The comparison of the 24-hour seismic noise data before and after the lockdown period indicates a considerable drop in environmental noise in Italy ( Bressan, 2020 ).

3. Impact of COVID-19 on the socio-economic domain

COVID-19 has created a global health crisis where countless people are dying, human suffering is spreading, and people's lives are being upended ( Nicola et al., 2020 ). It is not only just a health crisis but also a social and economic crisis, both of which are fundamental to sustainable development ( Pirouz et al., 2020 ). On 11 th March 2020, when WHO declared a global pandemic, 118,000 reported cases spanning 114 countries with over 4,000 fatalities had been reported. It took 67 days from the first reported case to reach 100,000 cases, 11 days for the second 100,000, and just four days for the third ( United Nations Development Programme (UNDP), 2020 ). This has overwhelmed the health systems of even the richest countries with doctors being forced to make the painful decision of who lives and who dies. The COVID-19 pandemic has pushed the world into uncertainty and countries do not have a clear exit strategy in the absence of a vaccine. This pandemic has affected all segments of society. However, it is particularly damaging to vulnerable social groups, including people living in poverty, older persons, persons with disabilities, youths, indigenous people and ethnic minorities. People with no home or shelter such as refugees, migrants, or displaced persons will suffer disproportionately, both during the pandemic and in its aftermath. This might occur in multiple ways, such as experiencing limited movement, fewer employment opportunities, increased xenophobia, etc. The social crisis created by the COVID-19 pandemic may also increase inequality, discrimination and medium and long-term unemployment if not properly addressed by appropriate policies.

The protection measures taken to save lives are severely affecting economies all over the world. As discussed previously, the key protection measure adopted universally is the lockdown, which has forced people to work from home wherever possible. Workplace closures have disrupted supply chains and lowered productivity. In many instances, governments have closed borders to contain the spread. Other measures such as travel bans and the prohibition of sporting events and other mass gatherings are also in place. In addition, measures such as discouraging the use of public transport and public spaces, for example, restaurants, shopping centres and public attractions are also in place in many parts of the world. The situation is particularly dire in hospitality-related sectors and the global travel industry, including airlines, cruise companies, casinos and hotels which are facing a reduction in business activity of more than 90% ( Fernandes, 2020 ). The businesses that rely on social interactions like entertainment and tourism are suffering severely, and millions of people have lost their jobs. Layoffs, declines in personal income, and heightened uncertainty have made people spend less, triggering further business closures and job losses ( Ghosh, 2020 ).

A key performance indicator of economic health is Gross Domestic Product (GDP), typically calculated on a quarterly or annual basis. IMF provides a GDP growth estimate per quarter based on global economic developments during the near and medium-term. According to its estimate, the global economy is projected to contract sharply by 3% in 2020, which is much worse than the 2008 global financial crisis ( International Monetary Fund (IMF), 2020 ). The growth forecast was marked down by 6% in the April 2020 World Economic Outlook (WEO) compared to that of the October 2019 WEO and January 2020 WEO. Most economies in the advanced economy group are expected to contract in 2020, including the US, Japan, the UK, Germany, France, Italy and Spain by 5.9%, 5.4%, 6.5%, 7.0%, 7.2%, 9.1%, and 8.0% respectively. Fig. 15 a shows the effect of COVID-19 on the GDP of different countries around the globe. On the other hand, economies of emerging market and developing economies, excluding China, are projected to contract by only 1.0% in 2020. The economic recovery in 2021 will depend on the gradual rolling back of containment efforts in the latter part of 2020 that will restore consumer and investor confidence. According to the April 2020 WEO, the level of GDP at the end of 2021 in both advanced and emerging market and developing economies is expected to remain below the pre-virus baseline (January 2020 WEO Update), as shown in Fig. 15 b.

(a) Quarterly World GDP. 2019:Q1 =100, dashed line indicates estimates from January 2020 WEO; (b) GDP fall due to lockdown in selected countries.

A particular example of a country hardest hit by COVID-19 is Italy. During the early days of March, the Italian government imposed quarantine orders in major cities that locked down more than seventeen million people ( Andrews, 2020 ). The mobility index data by Google for Italy shows there has been a significant reduction in mobility (and therefore economic activity) across various facets of life. The reported decline of mobility in retail and recreation, grocery and pharmacy, transit stations and workplaces were 35%, 11%, 45% and 34% respectively ( Rubino, 2020 ). The Italian economy suffered great financial damage from the pandemic. The tourism, and hospitality sectors were among those most severely affected by foreign countries prohibiting travel to and from Italy, and by the government's national lockdowns in early March ( Brunton, 2020 ). A March 2020 study in Italy showed that about 99% of the companies in the housing and utility sector said the epidemic had affected their industry. In addition, transport and storage was the second most affected sector. Around 83% of companies operating in this sector said that their activities had been affected by the coronavirus ( Statista, 2020 ) pandemic. In April 2020, Italian Minister Roberto Gualtieri estimated a 6% reduction in the GDP for the year 2020 ( Bertacche et al., 2020 ). The government of Italy stopped all unnecessary companies, industries and economic activities on 21 st March 2020. Therefore The Economist estimates a 7% fall in GDP in 2020 ( Horowitz, 2020 ). The Economist predicted that the Italian debt-to-GDP ratio would grow from 130% to 180% by the end of 2020 ( Brunton, 2020 ) and it is also assumed that Italy will have difficulty repaying its debt ( Bertacche et al., 2020 ).

4. Impact of COVID-19 on the energy domain

COVID-19 has not only impacted health, society and the economy but it has also had a strong impact on the energy sector ( Chakraborty and Maity, 2020 ; Abu-Rayash and Dincer, 2020 ). World energy demand fell by 3.8% in the first quarter (Q1) of 2020 compared with Q1 2019. In Q1 of 2020, the global coal market was heavily impacted by both weather conditions and the downturn in economic activity resulting in an almost 8% fall compared to Q1 2019. The fall was primarily in the electricity sector as a result of substantial declines in demand (-2.5%) and competitive advantages from predominantly low-cost natural gas. The market for global oil has plummeted by almost 5%. Travel bans, border closures, and changes in work routines significantly decreased the demand for the use of personal vehicles and air transport. Thus rising global economic activity slowed down the use of fuel for transportation ( Madurai Elavarasan et al., 2020 ). In Q1 2020, the output from nuclear energy plants decreased worldwide, especially in Europe and the US, as they adjusted for lower levels of demand. Demand for natural gas dropped significantly, by approximately 2% in Q1 2020, with the biggest declines in China, Europe, and the United States. In the Q1 2020, the need for renewable energy grew by around 1.5%, driven in recent years by the increasing output of new wind and solar plants. Renewable energy sources substantially increased in the electricity generation mix, with record hourly renewable energy shares in Belgium, Italy, Germany, Hungary, and East America. The share of renewable energy sources in the electricity generation mix has increased. Table 2 shows the effect of COVID-19 outbreak on the energy demand around the world.

Impact of COVID-19 on global energy sector ( AEMO, 2020 ; CIS Editorial, 2020 ; Eurelectric, 2020 ; Livemint, 2020 ; Renewable Energy World, 2020 ; S&P Global, 2020 ; Madurai Elavarasan et al., 2020 ).

Different areas have implemented lockdown of various duration. Therefore, regional energy demand depends on when lockdowns were introduced and how lockdowns influence demand in each country. In Korea and Japan, the average impact on demand is reduced to less than 10%, with lower restrictions. In China, where the first COVID-19 confinement measures were introduced, not all regions faced equally stringent constraints. Nevertheless, virus control initiatives have resulted in a decline of up to 15% in weekly energy demand across China. In Europe, moderate to complete lockdowns were more radical. On average, a 17% reduction in weekly demand was experienced during temporary confinement periods. India's complete lockdown has cut energy requirements by approximately 30%, which indicates yearly energy needs are lowered by 0.6% for each incremental lockdown week ( International Energy Agency (IEA) 2020 ).

The International Energy Agency (IEA) has predicted an annual average decline in oil production of 9% in 2020, reflecting a return to 2012 levels. Broadly, as electricity demand has decreased by about 5% throughout the year, coal production may fall by 8%, and the output of coal-fired electricity generation could fall by more than 10%. During the entire year, gas demand may fall far beyond Q1 2020 due to a downward trend in power and industrial applications. Nuclear energy demand will also decrease in response to reduced electricity demand. The demand for renewable energies should grow due to low production costs and the choice of access to many power systems. Khan et al. (2020) reported that international trade is significantly and positively dependent on renewable energy. In addition, sustainable growth can be facilitated through the consumption of renewable energy which improves the environment, enhances national image globally and opens up international trade opportunities with environmentally friendly countries ( Khan et al., 2021 ). As such, policies that promote renewables can result in economic prosperity, create a better environment as well as meet critical goals for sustainable development ( Khan et al., 2020 ).

5. Preventive measures to control COVID-19 outbreak

COVID-19 is a major crisis needing an international response. Governments will ensure reliable information is provided to assist the public in combating this pandemic. Community health and infection control measures are urgently needed to reduce the damage done by COVID-19 and minimise the overall spread of the virus. Self-defence techniques include robust overall personal hygiene, face washing, refraining from touching the eyes, nose or mouth, maintaining physical distance and avoiding travel. In addition, different countries have already taken preventive measures, including the implementation of social distancing, medicine, forestation and a worldwide ban on wildlife trade. A significant aim of the community health system is to avoid SARS-CoV-2 transmission by limiting large gatherings. COVID-19 is transmitted by direct communication from individual to individual. Therefore, the key preventive technique is to limit mass gatherings. Table 3 shows the impact of lockdown measures on the recovery rate of COVID-19 infections. The baseline data for this table is the median value, for the corresponding day of the week, during the 5-week period 3 rd January to 6 th February 2020.

Mobility index report of different countries ( Ghosh, 2020 ; Johns Hopkins University (JHU), 2020 ; Worldometer, 2020 ).

As of today, no COVID-19 vaccine is available. Worldwide scientists are racing against time to develop the COVID-19 vaccine, and WHO is now monitoring more than 140 vaccine candidates. As of 29 th September 2020, about 122 candidates have been pre-clinically checked, i.e. determining whether an immune response is caused when administering the vaccine to animals ( Biorender, 2020 ). About 45 candidates are in stage I where tests on a small number of people are conducted to decide whether it is effective ( Biorender, 2020 ). About 29 candidates are in Phase II where hundreds of people are tested to assess additional health issues and doses ( Biorender, 2020 ). Only 14 candidates are currently in Phase III, where thousands of participants are taking a vaccine to assess any final safety concerns, especially with regard to side effects ( Biorender, 2020 ). 3 candidates are in Phase IV, where long-term effects of the vaccines on a larger population is observed ( Biorender, 2020 ). The first generation of COVID-19 vaccines is expected to gain approval by the end of 2020 or in early 2021 ( Peiris and Leung, 2020 ). It is anticipated that these vaccines will provide immunity to the population. These vaccines can also reduce the transmission of SARS-CoV-2 and lead to a resumption of a pre-COVID-19 normal. Table 4 shows the list of vaccines that have been passed in the pre-clinical stage. In addition, according to the COVID-19 vaccine and therapeutics tracker, there are 398 therapeutic drugs in development. Of these, 83 are in the pre-clinical phase, 100 in Phase I, 224 in Phase II, 119 in Phase III and 46 in Phase IV ( Biorender, 2020 ).

List of vaccines that have passed the pre-clinical stage ( Biorender, 2020 ).

In addition to the above, forestation and a worldwide ban on wildlife trade can also play a significant role in reducing the spread of different viruses. More than 30% of the ground area is covered with forests. The imminent increase in population contributes to deforestation in agriculture or grazing for food, industries and property. The rise in ambient temperature, sea levels and extreme weather events affects not only the land and environment but also public health ( Ruscio et al., 2015 ; Arora and Mishra, 2020 ). Huge investment has been made into treatments, rehabilitation and medications to avoid the impact of this epidemic. However, it is important to focus on basic measures, e.g. forestation and wildlife protection. The COVID-19 infection was initially spread from the Seafood Market, Wuhan, China. Therefore, China temporarily banned wildlife markets in which animals are kept alive in small cages. It has been reported that 60% of transmittable diseases are animal-borne, 70% of which are estimated to have been borne by wild animals ( Chakraborty and Maity, 2020 ). Deforestation is also related to various kinds of diseases caused by birds, bats, etc. ( Afelt et al., 2018 ). For example, COVID-19 is a bat-borne disease that is transmitted to humans. Therefore, several scientists have advised various countries to ban wildlife trade indefinitely so that humans can be protected from new viruses and global pandemics like COVID-19.

6. Conclusion

In this article, comprehensive analyses of energy, environmental pollution, and socio-economic impacts in the context of health emergency events and the global responses to mitigate the effects of these events have been provided. COVID-19 is a worldwide pandemic that puts a stop to economic activity and poses a severe risk to overall wellbeing. The global socio-economic impact of COVID-19 includes higher unemployment and poverty rates, lower oil prices, altered education sectors, changes in the nature of work, lower GDPs and heightened risks to health care workers. Thus, social preparedness, as a collaboration between leaders, health care workers and researchers to foster meaningful partnerships and devise strategies to achieve socio-economic prosperity, is required to tackle future pandemic-like situations. The impact on the energy sector includes increased residential energy demand due to a reduction in mobility and a change in the nature of work. Lockdowns across the globe have restricted movement and have placed people primarily at home, which has, in turn, decreased industrial and commercial energy demand as well as waste generation. This reduction in demand has resulted in substantial decreases in NO 2, PM, and environmental noise emissions and as a consequence, a significant reduction in environmental pollution. Sustainable urban management that takes into account the positive benefits of ecological balance is vital to the decrease of viral infections and other diseases. Policies that promote sustainable development, ensuring cities can enforce recommended measures like social distancing and self-isolation will bring an overall benefit very quickly. The first generation of COVID-19 vaccines is expected to gain approval by the end of 2020 or in early 2021, which will provide immunity to the population. It is necessary to establish preventive epidemiological models to detect the occurrence of viruses like COVID-19 in advance. In addition, governments, policymakers, and stakeholders around the world need to take necessary steps, such as ensuring healthcare services for all citizens, supporting those who are working in frontline services and suffering significant financial impacts, ensuring social distancing, and focussing on building a sustainable future. It is also recommended that more investment is required in research and development to overcome this pandemic and prevent any similar crisis in the future.

Safe outdoor activities during the COVID-19 pandemic

T he coronavirus disease 2019 (COVID-19) pandemic has affected activities for many people. With COVID-19 vaccinations, testing and treatment, events and travel are coming back in many places.

But as waves of COVID-19 cases, also called outbreaks, happen, it's important to stay flexible with your plans.

Despite the changes caused by the COVID-19 pandemic, there's still plenty of fun to be had. In fact, seeking out fun activities may be even more important now. Doing something you enjoy can distract you from problems. And it can help you cope with life's challenges.

Depending on the weather where you live, many activities may be available. Heading outdoors can be a good way to have fun safely, no matter what COVID-19 cases look like in your community.

Why choose outdoor activities?

It's much harder to catch the virus that causes COVID-19 when you are outside.

The COVID-19 virus is mainly spread from person to person among those in close contact. The virus spreads through respiratory droplets from your lungs, mouth and nose. These droplets are released into the air when you talk, cough, speak, breath or sneeze.

In small places or spaces with air flow, also called ventilation, that is poor, the COVID-19 virus can stay in the air for minutes or hours.

When you're outside, fresh air is always moving, scattering these droplets. So, you're less likely to breathe in enough of the respiratory droplets that have the virus that causes COVID-19 to get the virus.

Places at high risk of COVID-19 spread are those that have a high number of people hospitalized with COVID-19 or a high number of new COVID-19 cases, according to the Centers for Disease Control and Prevention (CDC).

In areas of medium or high risk, the CDC suggests people wear well-fitted masks indoors in public, among other tactics.

The CDC and other health agencies also suggest that outdoor group activities are less risky than indoor ones in spreading the virus that causes COVID-19.

Outdoor activities that are near where you live and allow plenty of space between you and others pose a lower risk of spread of the COVID-19 virus than indoor activities do.

Being outside offers other benefits, too. It offers an emotional boost and can help you feel less tense, stressed, angry or depressed. And sunlight can give your body vitamin D, too.

Low-risk ways to move more

Coming into close contact with people who don't live with you makes your risk of being exposed to the virus that causes COVID-19 go up. Keep in mind low-risk ways to be around people if your area is considered at medium or high risk of spreading the COVID-19 virus. In general, any activity that allows you to keep your distance from others is a lower risk activity.

You can enjoy many activities close to home, whether you're visiting your favorite public, state or national park. Or you may even be spending time in your neighborhood. Some activities may not be possible during some seasons. But there are many ways to be active outdoors throughout the year. Get moving with outdoor activities during the COVID-19 pandemic:

Walking, running and hiking.
Rollerblading and biking.
Fishing and hunting.
Rock or ice climbing.
Kayaking, canoeing, diving, boating or sailing.
Skiing, including cross-country and downhill skiing.
Ice skating.
Snowboarding.
Snowshoeing.
Fitness classes, held outside or virtually, that allow distance.

Choose routes that make it easy to keep your distance. If you live in an area with a medium or high risk of spread of the COVID-19 virus, the CDC suggests that you wear a well-fitted mask indoors in public. Don't wear a mask during activities in which it might get wet, such as swimming.

And don't let cold weather stop you from being active outdoors! Dress in layers. Protect your head, hands and feet. Then head outside for a winter hike or go cross-country skiing. And aim to keep a positive mindset about winter. This may help you to enjoy the season and winter activities more.

Low-risk social activities

Depending on your location and the weather, many other outdoor activities can be good low-risk choices:

Picnics. Pack food from home. Or pick up takeout from your favorite restaurant or food truck. In some places, you might be able to have food delivered to you. Take it to enjoy at your favorite public park. Or eat out on your patio or deck.
Outdoor farmers markets. Wear a mask when in crowded areas where it's hard to keep your distance from others.
Outdoor movies. Either at a drive-in theater or a community event, watching movies outdoors is something many people can enjoy together with plenty of physical distance.

Low- to moderate-risk outdoor activities

Some of these activities may not be available in all seasons and locations. But take advantage of them when the weather permits. Some ideas include:

Restaurant patio dining. Outdoor patio dining at uncrowded restaurants where patio tables are spaced apart is safer than indoor dining. Keep your distance from people in other areas of the restaurant. Avoid self-service food and drink options. And remember to wash your hands or use hand sanitizer when you enter and leave.

Camping. If you only have close contact only with people you live with, camping is low risk.

If you camp with people outside your household, camp in separate tents spaced away from each other. Avoid sharing camping supplies, including food and drinks. Pack hand soap, hand sanitizer, and supplies to clean and disinfect commonly touched surfaces.

Swimming pools and beaches. Close contact with others, not water itself, can make these activities risky. Water itself doesn't spread the virus that causes COVID-19 to people.

Gathering with small groups of friends. Allow for social distancing between people from different households, and meet outdoors in small groups. Skip the hugs and handshakes. Plan activities that don't need close contact, such as sidewalk chalk for kids and games such as kickball. And bring hand sanitizer.

Keep in mind that just getting together for a chat at a safe distance can offer a valuable opportunity to be with people you care about. And it can boost your mood at the same time.

Boating with friends. Canoeing, kayaking or rowing with people outside your household is riskier than doing these activities with only those from your own household.
Barbecues, campfires and outdoor potlucks. Grill out on the patio. Or if the weather is cool, bundle up in warm clothes and sit around a fire pit. In general, keep your gathering small and keep distance from others. Plan activities that don't need close contact. Wash your hands when you come and go from the gathering.
Sports and sporting events. Contact sports, such as wrestling and basketball, carry more COVID-19 risk than other options. Tennis, baseball, softball and soccer pose less risk because players can keep physical distance. It's important for spectators, players and coaches to keep their distance too. Wearing a mask that fits and is comfortable when at crowded events can prevent you from getting or spreading the virus that causes COVID-19. And use hand sanitizer. Ensure you have enough space between you and other spectators, whether you're standing, sitting in chairs or sharing bleachers.

High-risk outdoor activities

Risk increases with how long you spend with others. It also increases if someone who has COVID-19 was near you and coughing or doing an activity such as singing.

Being in large gatherings or crowds of people where it's difficult to stay a safe distance apart poses the highest risk. The larger the group and the longer people are together in these situations, the higher the risk. Weddings, festivals and parades are examples.

Think safety and enjoyment

As the COVID-19 pandemic continues, it's important to take care of yourself and those around you. Practice precautions. It's important to stay up to date with COVID-19 vaccines. Test for COVID-19 if you have symptoms. And cancel plans if someone may be sick.

When you are out, wash your hands often. Avoid touching your face. If you live in an area with a high risk of COVID-19, wear a well-fitted mask. If you are at high risk of serious illness from COVID-19, wear a mask when you are in an area that has a medium or high level of risk of COVID-19.

At the same time, well-being also includes doing things that make life worth living. With the right information, you can make thoughtful choices about ways to bring a sense of normalcy and joy to your life during the ups and downs of the COVID-19 pandemic.

How the SAT Changed My Life

An illustration of a man lying underneath a giant SAT prep book. The book makes a tent over him. He is smiling.

By Emi Nietfeld

Ms. Nietfeld is the author of the memoir “Acceptance.”

This month, the University of Texas, Austin, joined the wave of selective schools reversing Covid-era test-optional admissions policies, once again requiring applicants to submit ACT or SAT scores.

Many colleges have embraced the test-optional rule under the assumption that it bolsters equity and diversity, since higher scores are correlated with privilege. But it turns out that these policies harmed the teenagers they were supposed to help. Many low-income and minority applicants withheld scores that could have gotten them in, wrongly assuming that their scores were too low, according to an analysis by Dartmouth. More top universities are sure to join the reversal. This is a good thing.

I was one of the disadvantaged youths who are often failed by test-optional policies, striving to get into college while in foster care and homeless. We hear a lot about the efforts of these elite schools to attract diverse student bodies and about debates around the best way to assemble a class. What these conversations overlook is the hope these tests offer students who are in difficult situations.

For many of us, standardized tests provided our one shot to prove our potential, despite the obstacles in our lives or the untidy pasts we had. We found solace in the objectivity of a hard number and a process that — unlike many things in our lives — we could control. I will always feel tenderness toward the Scantron sheets that unlocked higher education and a better life.

Growing up, I fantasized about escaping the chaos of my family for the peace of a grassy quad. Both my parents had mental health issues. My adolescence was its own mess. Over two years I took a dozen psychiatric drugs while attending four different high school programs. At 14, I was sent to a locked facility where my education consisted of work sheets and reading aloud in an on-site classroom. In a life skills class, we learned how to get our G.E.D.s. My college dreams began to seem like delusions.

Then one afternoon a staff member handed me a library copy of “Barron’s Guide to the ACT .” I leafed through the onionskin pages and felt a thunderclap of possibility. I couldn’t go to the bathroom without permission, let alone take Advanced Placement Latin or play water polo or do something else that would impress elite colleges. But I could teach myself the years of math I’d missed while switching schools and improve my life in this one specific way.

After nine months in the institution, I entered foster care. I started my sophomore year at yet another high school, only to have my foster parents shuffle my course load at midyear, when they decided Advanced Placement classes were bad for me. In part because of academic instability like this, only 3 percent to 4 percent of former foster youth get a four-year college degree.

Later I bounced between friends’ sofas and the back seat of my rusty Corolla, using my new-to-me SAT prep book as a pillow. I had no idea when I’d next shower, but I could crack open practice problems and dip into a meditative trance. For those moments, everything was still, the terror of my daily life softened by the fantasy that my efforts might land me in a dorm room of my own, with endless hot water and an extra-long twin bed.

Standardized tests allowed me to look forward, even as every other part of college applications focused on the past. The song and dance of personal statements required me to demonstrate all the obstacles I’d overcome while I was still in the middle of them. When shilling my trauma left me gutted and raw, researching answer elimination strategies was a balm. I could focus on equations and readings, like the scholar I wanted to be, rather than the desperate teenager that I was.

Test-optional policies would have confounded me, but in the 2009-10 admissions cycle, I had to submit my scores; my fellow hopefuls and I were all in this together, slogging through multiple-choice questions until our backs ached and our eyes crossed.

The hope these exams instilled in me wasn’t abstract: It manifested in hundreds of glossy brochures. After I took the PSAT in my junior year, universities that had received my score flooded me with letters urging me to apply. For once, I felt wanted. These marketing materials informed me that the top universities offered generous financial aid that would allow me to attend free. I set my sights higher, despite my guidance counselor’s lack of faith.

When I took the actual SAT, I was ashamed of my score. Had submitting it been optional, I most likely wouldn’t have done it, because I suspected my score was lower than the prep-school applicants I was up against (exactly what Dartmouth found in the analysis that led it to reinstate testing requirements). When you grow up the way I did, it’s difficult to believe that you are ever good enough.

When I got into Harvard, it felt like a miracle splitting my life into a before and after. My exam preparation paid off on campus — it was the only reason I knew geometry or grammar — and it motivated me to tackle new, difficult topics. I majored in computer science, having never written a line of code. Though a career as a software engineer seemed far-fetched, I used my SAT study strategies to prepare for technical interviews (in which you’re given one or more problems to solve) that landed me the stable, lucrative Google job that catapulted me out of financial insecurity.

I’m not the only one who feels affection for these tests. At Harvard, I met other students who saw these exams as the one door they could unlock that opened into a new future. I was lucky that the tests offered me hope all along, that I could cling to the promise that one day I could bubble in a test form and find myself transported into a better life — the one I lead today.

Mystery in Japan as dangerous streptococcal infections soar to record levels

Health officials racing to identify cause of rise in streptococcal toxic shock syndrome, which has a 30% fatality rate

Experts warn that a rare but dangerous bacterial infection is spreading at a record rate in Japan , with officials struggling to identify the cause.

The number of cases in 2024 is expected to exceed last year’s record numbers, while concern is growing that the harshest and potentially deadly form of group A streptococcal disease – streptococcal toxic shock syndrome (STSS) – will continue to spread, after the presence of highly virulent and infectious strains were confirmed in Japan.

The National Institute of Infectious Diseases (NIID) said: “There are still many unknown factors regarding the mechanisms behind fulminant (severe and sudden) forms of streptococcus, and we are not at the stage where we can explain them.”

Provisional figures released by the NIID recorded 941 cases of STSS were reported last year. In the first two months of 2024, 378 cases have already been recorded, with infections identified in all but two of Japan’s 47 prefectures.

While older people are considered at greater risk, the group A strain is leading to more deaths among patients under 50, according to NIID. Of the 65 people under 50 who were diagnosed with STSS between July and December in 2023, about a third, or 21, died, the Asahi Shimbun newspaper reported.

Most cases of STSS are caused by a bacterium called streptococcus pyogenes. More commonly known as strep A – it can cause sore throats, mainly in children, and lots of people have it without knowing it and do not become ill.

But the highly contagious bacteria that cause the infection can, in some cases, cause serious illnesses, health complications and death, particularly in adults over 30. About 30% of STSS cases are fatal.

Older people can experience cold-like symptoms but in rare cases, the symptoms can worsen to include strep throat, tonsillitis, pneumonia and meningitis. In the most serious cases it can lead to organ failure and necrosis.

Some experts believe the rapid rise in cases last year were connected to the lifting of restrictions imposed during the coronavirus pandemic.

In May 2023, the government downgraded Covid-19’s status from class two – which includes tuberculosis and Sars – to class five, placing it on a legal par with seasonal flu. The change meant local authorities were no longer able to order infected people to stay away from work or to recommend hospitalisation.

The move also prompted people to lower their guard, in a country where widespread mask wearing, hand sanitising and avoiding the “three Cs” were credited with keeping Covid-19 deaths comparatively low. About 73,000 Covid-19 deaths were recorded compared with more than 220,000 in Britain, which has a population just over half that of Japan.

Ken Kikuchi, a professor of infectious diseases at Tokyo Women’s Medical University, says he is “very concerned” about the dramatic rise this year in the number of patients with severe invasive streptococcal infections.

He believes the reclassification of Covid-19 was the most important factor behind the increase in streptococcus pyogenes infections. This, he added, had led more people to abandon basic measures to prevent infections, such as regular hand disinfection.

“In my opinion, over 50% Japanese people have been infected by Sars-CoV-2 [the virus that causes Covid-19],” Kikuchi tells the Guardian. “People’s immunological status after recovering from Covid-19 might alter their susceptibility to some microorganisms. We need to clarify the infection cycle of severe invasive streptococcal pyogenes diseases and get them under control immediately.”

Streptococcal infections, like those of Covid-19, are spread through droplets and physical contact. The bacterium can also infect patients through wounds on the hands and feet.

Strep A infections are treated with antibiotics, but patients with the more severe invasive group A streptococcal disease are likely to need a combination of antibiotics and other drugs, along with intensive medical attention.

Japan’s health ministry recommends that people take the same basic hygiene precautions against strep A that became a part of everyday life during the coronavirus pandemic.

“We want people to take preventive steps such as keeping your fingers and hands clean, and exercising cough etiquette,” the health minister, Keizo Takemi, told reporters earlier this year, according to the Japan Times.
