Stress is the No. 1 reason U.S. teachers left the profession before and during the COVID-19 pandemic, a new poll reveals.

Nearly 1,000 former public school teachers were polled in December. Three-quarters said their job was often or always stressful during their final year in the classroom.

Stress was nearly twice as common as poor pay as a reason for quitting, according to the resu...

Hungry for good news on the pandemic? One epidemiologist believes Americans might reach herd immunity to the new coronavirus as soon as late spring.

That's the view held by Suzanne Judd, a professor with the school of public health at the University of Alabama (UA) at Birmingham. To come to that conclusion, she reviewed recent research and data from her home state.

"I really am star...

Protective immune system antibodies that develop after being infected with COVID-19 last for at least a few months, a new study suggests. And reinfection does seem to be relatively rare.

That could have big implications for public health and societies, including allowing people to return to physical workplaces and go to school, the researchers said.

"The data from this study suggest...

During the pandemic, people with asthma have worried that their respiratory condition might raise their risk of severe illness or death from COVID-19, but new research findings should calm their fears.

After analyzing data from 57 studies that included a total of over 587,000 people, scientists discovered that rates of asthma among people with COVID-19 were similar to rates in the general...

It's been nearly a year since David Speal, 38, first fell ill with COVID-19, but a racing heartbeat remains a regular reminder of his brush with the new coronavirus.

Even the littlest thing -- not eating at the right time, not drinking enough water, too much exercise, a stressful encounter -- can send Speal's heartbeat soaring as high as 150 beats per minute.

"My autonomic nervous s...

Many older Americans lack knowledge about antibiotics, with some admitting to using leftover medication, a new survey reveals.

More than 2,200 adults, aged 50 to 80, were questioned. Nine out of 10 said they're cautious about using antibiotics, and nearly that number knew that overuse of the drugs can lead to them becoming ineffective, according to the University of Michigan National Poll...

Researchers have identified more than 140,000 viruses that live in the human gut, including half that were previously unknown.

The number and variety of viruses found in more than 28,000 gut microbiome samples gathered from different parts of the world are surprisingly high, according to the study authors.

The researchers added that their findings will lead to new research to learn ...

The emergence of new SARS-CoV-2 variants could require a quick pivot on the part of pharmaceutical and medical device companies, to help stay one step ahead of COVID-19.

The U.S. Food and Drug Administration issued guidelines Monday encouraging drug and test developers to pay attention to new coronavirus variants and be prepared to make that pivot if necessary.

The guidance provides...

Worried or wondering about COVID-19 vaccines?

Many Americans are, so experts at Penn State Health are offering some reassuring insight.

Many patients with mild to moderate COVID-19 could become "long haulers," suffering symptoms months after they clear their non-life-threatening infection, new research shows.

About 33% of COVID-19 patients who were never sick enough to require hospitalization continue to complain months later of symptoms like fatigue, loss of smell or taste and "brain fog," University of Washington (UW) r...

The greatest threat from COVID-19 has been for Black and Hispanic Americans, who are three times more likely to be hospitalized and about twice as likely to die from an infection with the novel coronavirus, compared with white people.

Now, street-level community groups are stepping in with innovative ways to overcome longstanding racial disparities in health care and help step up vaccinat...

Children have largely been spared severe COVID-19 infection, and new research hints at why.

In the study, children's immune systems attacked the new coronavirus faster and more aggressively than adults' immune systems did, the findings showed.

The researchers analyzed blood samples from 48 children and 70 adults who lived in 28 households in Melbourne, Australia, and who were infect...


Scientists may have discovered why cold sores caused by herpes simplex virus (HSV) are triggered by stress, illness and sunburn.

The finding could lead to new ways to prevent recurring cold sores and herpes-related eye disease, U.S. and British researchers say.

More than half of Americans are infected with herpes simplex virus. It is spread throu...

When New York City was the epicenter of the coronavirus pandemic last spring in the United States, nearby Mount Sinai South Nassau hospital was treating more than 400 COVID-19 patients at one time, remembers Dr. Aaron Glatt.

Infectious disease experts had warned for years about the potential for another pandemic, yet the scale of this pandemic was unprecedented according to Glatt, wh...

For parents with questions about COVID-19 vaccines and children, Johns Hopkins Medicine experts offer answers.

While vaccinations for adults are underway in the United States, clinical trials for the first U.S. Food and Drug Administration-authorized COVID-19 vaccines haven't yet been completed for children and teens younger than 16.

Before that age group can receive a vaccine, the ...

When choosing a face mask to help prevent the spread of COVID-19, it seems like the choices are endless.

To make the decision a little easier, researchers at the University of British Columbia in Vancouver, Canada, tested several styles in 41 types of fabric.

The upshot: A mask made of two layers of low-thread-count quilting cotton paired with a three-ply dried baby wipe as a filter...

Here's some good news for people who've had solid organ transplants and have weakened immune systems: mRNA coronavirus vaccines are safe for these vulnerable folks, new research shows.

The participants, median age 48, were r...

It would be nice if it were true, but a bout of the common cold won't protect you against the new coronavirus infection, researchers report.

Colds are caused by seasonal coronaviruses (CoVs) and previous studies have suggested that exposure to cold coronaviruses may safeguard against the SARS-CoV-2 coronavirus that causes COVID-19.

To find out if that was true, researchers analyzed...

Certain genetic factors in people with Down syndrome may increase their COVID-19 risks.

Previous studies have found that people with Down syndrome are 10 times more likely to die from COVID-19, and experts have said they should be among those given priority for vaccination.

In this new study, Spanish researchers examined genetic differences in people with Down syndrome that might af...

Could it be that a strange-looking creature known as a pangolin was the conduit by which the new coronavirus jumped to humans and prompted an international pandemic?

New research suggests the theory is a plausible one.

Pangolins are sold for food in live-animal "wet markets" in China -- facilities that have long been suspected of being ground zero for the spread of viruses originat...

An experimental antiviral drug known as peginterferon lambda can speed up COVID-19 patients' ability to shed the virus and recover, scientists report.

"One of the important things about this treatment that's different from the other things that have been studied for COVID-19 is that this is working on the person, not on the virus. So it doesn't depend at all on the strain or the sequence ...

His second COVID-19 vaccine shot wiped Dr. Greg Poland out.

Poland, 65, said he suffered five hours of shaking chills, fever up to 101 degrees, severe headache, nausea, ringing in his ears and a sore arm after getting his booster dose of the Moderna vaccine.

"I've never had a reaction to a vaccine like that," said Poland, director of the Mayo Clinic's Vaccine Research Group. "Ironic...

Children in day care centers had low coronavirus infection rates early in the pandemic, and are unlikely sources of COVID-19 transmission, a new study from France finds.

COVID-19 can infect people of all ages, but children tend to develop mild, if any, symptoms, and very rarely need to be hospitalized. Very young children's role as asymptomatic coronavirus spreaders remains unknown and th...

Keep flossing: A new study finds that gum disease may raise the chances of hospitalization or death if COVID-19 strikes.

The reason? Gum disease can be a sign of inflammation throughout the body.

"It is well-established that systemic inflammation is not only linked with periodontal disease, but to several other respiratory diseases as well," explained Dr. James Wilson, president of...

Here's a new reason to make sure your kids get their seasonal flu shot.

A new study showed that it reduces kids' risk for symptoms and severe illness if they get COVID-19.

That conclusion is drawn from medical records of more than 900 children diagnosed with COVID-19 between February and August of last year.

Those who had their current flu shot were less likely to have COVID-1...

COVID-19 vaccine shortages are leading some to question whether the United States would be better off simply trying to give a single dose to as many people as possible.

This view has been bolstered by early data from Israel indicating that a single dose of vaccine is extremely effective and can drive down infection rates.

But public health experts remain adamant that the approved tw...

It's a link few might have considered, but a new study indicates that climate change may have prompted the COVID-19 pandemic.

Rising temperatures caused by greenhouse emissions have boosted the growth of bat-friendly forest habitat in China's southern province of Yunnan and neighboring areas, making the region a hotspot for bat-borne coronaviruses, the researchers explained. Genetic data ...

THURSDAY, Feb. 4, 2020 (HealthDay) -- Being infected with the virus that causes COVID-19 is not a foolproof shield against reinfection, a small preliminary study warns.

The finding stems from tracking nearly 3,250 young U.S. Marine recruits between May and October. Of those, 189 had previously tested positive for the SAR-CoV-2 virus. During the six-week study itself, 10% of those who had ...

Just one dose of Pfizer's coronavirus vaccine might be enough to largely protect people from being infected with COVID-19, preliminary research shows.

The vaccine became 90% effective 21 days after the first shot in a two-dose regimen, said British researchers who looked at data from Israel, where the vaccine has been rolled out to a large portion of the population.

"A second d...

Like influenza, could COVID-19 evolve to wax and wane with the seasons? New research suggests it might.

Early in the pandemic, some experts suggested that SARS-CoV-2 -- the virus that causes COVID-19 -- may behave like many other coronaviruses that circulate more widely in fall and winter.

To find out if that could be true, researchers analyzed COVID-19 data -- including cases, deat...

Previous exposure to other coronaviruses may enhance a person's immune response to COVID-19 infection, but new research suggests that antibodies triggered by the SARS outbreak of 2003 provide only limited protection against the new coronavirus.

Antibodies are blood proteins made by the immune system to protect against infection, the Oregon Health & Science University (OHSU) researchers ex...

A seriously ill, immunocompromised patient with COVID-19 was cured with an infusion of convalescent plasma from her son-in-law, according to a new study that details the case.

The turnaround in the 72-year-old's condition was profound. Her 104-degree fever rapidly dropped. In three days, the virus was no longer detectable in her respiratory swabs, and in four days she was discharged fr...

All Alzheimer's disease patients and their family caregivers should be vaccinated against COVID-19, the Alzheimer's Foundation of America says.

Irene Greenhalgh, 83, considers herself a pretty computer-savvy senior, but even she got lost in a maze of websites and e-mails trying to get an appointment for her COVID-19 vaccine.

One health provider's e-mail provided links to sites that were giving vaccinations, but the dates listed were a week old. A board of health's website proved glitchy and unusable.

After weeks of searchin...

The first monthly shots to treat adults with HIV were approved by the U.S. Food and Drug Administration on Thursday.

"Currently, the standard of care for patients with HIV includes patients taking daily pills to adequately manage their condition. This approval will allow some patients the option of receiving once-monthly injections in lieu of a daily oral treatment regimen," said Dr. John...

Previous coronavirus infections might prime the immune system to fight the new coronavirus that causes COVID-19, a new study suggests.

There are numerous types of coronaviruses, including many harmless ones that cause mild upper respiratory infections similar to the common cold.

Besides SARS-CoV-2 -- the virus that causes COVID-19 -- other deadly coronaviruses include MERS-CoV, whic...

When intensive care units are swamped with COVID-19 patients, death rates may climb, a new study finds.

Looking at data from 88 U.S. Department of Veterans Affairs (VA) hospitals, researchers found a pattern: COVID-19 patients were nearly twice as likely to die during periods when ICUs were dealing with a surge of patients with the illness.

The results, experts said, do not necessar...

Women who have COVID-19 during childbirth are more likely to face complications than moms-to-be without the coronavirus, researchers say.

Fortunately, the absolute risk for complications for any one woman is very low (less than 1%). But the relative risks for problems -- such as clotting and early labor -- are significant, the new study found.

Still, "the findings here, truly, are t...

Want to get the most out of your COVID-19 vaccine? Make sure you get some good rest before you get your shot, sleep experts say.

That's because adequate sleep is an important factor in a strong immune system.

"As COVID-19 vaccines are being distributed, it is of utmost importance that patients continue to prioritize their sleep to maintain optimal health," American Academy of Sleep ...

If you're trying to decide whether to have your child tested for COVID-19, talk with your pediatrician, the American Academy of Pediatrics (AAP) suggests.

Children and teens with COVID-19 symptoms should be tested immediately. This is especially important if they're going to school, playing sports or have in-person jobs, according to the academy.

Testing is also recommended before m...

A combination of mask use, social distancing and routine testing would eliminate nearly all COVID-19 infections on U.S. college campuses, a new study claims.

Using a computer model that simulated a semester of a mid-sized college (5,000 students and 1,000 faculty), researchers assessed the effectiveness and cost of 24 combinations of four common preventive strategies: social distancing; m...

The bad news? COVID-19 may be around for a long, long time. The good news? Even if it does, new research suggests it could very well end up being just another mild illness, bringing with it inconvenience and discomfort, but rarely hospitalization or death.

Why? The theory is rooted in the epidemiology patterns previously followed by four other coronaviruses. All have been in circulation f...

Folks who've gotten through a COVID-19 infection might naturally question whether they need to get a coronavirus vaccination when their turn comes.

Experts say they really need the shot anyway, because even after having COVID they might be vulnerable to reinfection.

"We're encouraging people if they meet the other criteria to get immunized because we don't know how long either natur...

Unlike regular pneumonia, COVID-19 pneumonia spreads like many "wildfires" throughout the lungs, researchers say.

This may explain why COVID-19 pneumonia lasts longer and causes more harm than typical pneumonia, according to the researchers at Northwestern Medicine in Chicago.

The research team said that their aim is to make COVID-19 more like a bad cold.

For the study, the t...

Even people with mild cases of COVID-19 may commonly feel run down and unwell months later, a new study suggests.

The study, of patients at one Irish medical center, found that 62% said they had not returned to "full health" when they had a follow-up appointment a few months after their COVID-19 diagnosis. Nearly half complained of ongoing fatigue.

Surprisingly, the severity of pati...

The COVID-19 pandemic may feel like it's been going on forever, but it's important to keep up safety measures, a mental health expert says.

Dr. Olusinmi Bamgbose, a psychiatrist at Cedars-Sinai in Southern California -- an area that's facing an unprecedented surge in coronavirus cases -- offered some tips for keeping up with pandemic safeguards and some theories about why people may be ba...

Blood plasma from people recovering from COVID-19 could help prevent severe illness in older patients newly infected with the virus, a small new Argentinian study finds.

The findings give new hope to the notion that so-called "convalescent plasma" might have a role to play in treating COVID-19. Earlier studies had been disappointing, showing the treatment had little effect on people with...

The American Red Cross is urging COVID-19 survivors to donate blood plasma for hospital patients who need it to recover.

As an incentive to help boost the national convalescent plasma shortage, the Red Cross has teamed up with the National Football League and is offering donors a chance to win two tickets to next year's Super Bowl LVI in Los Angeles.

The Red Cross is especially aski...

A return to normal life in America might happen sooner than many expect, one of the nation's leading vaccine experts told HD Live! this week.
