The COVID-19 pandemic significantly shortened life expectancy in the United States, especially among Black people and Hispanics, a new study says.

With more than 336,000 COVID-19 deaths nationwide last year, researchers decided to examine the pandemic's impact on life expectancy.

The projection: Due to pandemic deaths, life expectancy at birth for Americans will shrink by 1.13 years...

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...

After SARS-CoV-2 exposure, a 14-day quarantine is standard among university athletes. But shorter quarantines for these athletes, along with mid-quarantine testing, may improve their compliance without increasing the risk that they'll infect others, a new study suggests.

Researchers analyzed data from 620 U.S. college athletes who tested positive for SARS-CoV-2 while in quarantine after e...

THURSDAY, Jan. 14, 2021 (HealthDay News) -- 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 follo...

Most folks infected with COVID-19 will only have mild or moderate illness -- but that means they'll still be stuck at home and feeling really lousy.

What's the best way to cope?

In many ways, you want to behave as you would if you were suffering from a cold or the flu, said infectious disease expert Dr. Aaron Glatt.

"The general good advice we give to people is eat well, make ...

U.S. colleges could be COVID-19 superspreader sites, and the first two weeks of classes are the most dangerous, researchers warn.

They studied 30 campuses nationwide with the highest numbers of reported coronavirus cases and found that more than half had spikes that peaked well above 1,000 cases per 100,000 people per week within the first two weeks of class.

On some campuses, 1 in ...

New research offers a novel explanation for the long-term brain problems many COVID-19 patients experience.

Many coronavirus patients report headaches and "brain fog" for weeks or months after they recover from respiratory symptoms. It's been believed that these lingering neurological issues are the result of nerve cell damage, but the new study suggests that the virus may instead be str...

In a finding that highlights another health consequence of the coronavirus pandemic, researchers report that the risk of dying from heart disease increased during the coronavirus lockdowns last spring, likely because people were too scared to go to the hospital.

But the dangers of not seeking treatment for a medical emergency far outweigh that of catching COVID-19, especially now that pre...

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...

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.

By Nov. 15 of last year, roughly 47 million Americans -- about 14.5% of the U.S. population -- had already been infected with the new coronavirus, a new study finds.

That's much higher than the close to 11 million known U.S. cases of infection that were recorded by that date, the researchers said, because reported cases "do not represent the full SARS-CoV-2 disease burd...

THURSDAY, Dec. 31, 2020 -- Folks who contract COVID-19 can expect to gain some durable immunity against future infection, according to a new study of memory cells within the immune systems of coronavirus patients.

Previous studies have raised concern that COVID-19 patients might lose their immunity quickly once they recover, because the first wave of coronavirus antibodies tends to wane a...

THURSDAY, Dec. 31, 2020 -- A new and more infectious variant of the COVID-19 virus has shown up in separate cases in Colorado and California, weeks after it first emerged in the United Kingdom.

Doctors on the pandemic's front line say people shouldn't panic, but should definitely adhere even more closely to proven infection control measures, like mask wearing and social distancing.

...

Blood vessel damage and inflammation in the brains of deceased COVID-19 patients suggest the damage is not caused by the virus, but the body's immune response to it.

Researchers from the U.S. National Institutes of Health (NIH) consistently found signs of damage caused by thinning and leaky brain blood vessels in tissue samples from patients who died shortly after getting COVID-19.

...

As 2020 careens to a close, one thing is clear: With infections topping 19 million and a death toll over 333,000, the COVID-19 pandemic has upended nearly every facet of American life.

As a new year nears, two leaders in the response to the pandemic talked over mistakes made, hard lessons learned and new reasons for hope.

No one can say the United States has performed well against C...


Keep your distance. Although wearing a mask can limit transmission of droplets that spread COVID-19, it may not be enough unless people also stay at least six feet apart, new research shows.

Researchers at New Mexico State University in Las Cruces found that at distances of less than six feet, enough droplets to potentially cause illness still made it through several masks made of co...

For Americans who are worried about the new coronavirus variant that is circulating in Britain, experts in the United States urge everyone to stay calm.

Though many Americans would support a COVID-19 vaccine mandate, a Gallup survey finds there is no clear majority in favor of it.

The Gallup Panel conducted the online survey of 2,730 U.S. adults between Sept. 14 and 27.

Nearly 49% of respondents said they would "accept" a state mandate requiring children to be vaccinated in order to attend school. But support fell to 41% when respo...

There's no evidence of a link between COVID-19 and a serious neurological condition called Guillain-Barré syndrome, British researchers say.

Guillain-Barré syndrome is a rare autoimmune condition that attacks the peripheral nervous system, typically causing numbness, weakness and pain. In severe cases, it can cause paralysis and is sometimes fatal.

The exact cause isn't known, but...

As a rule, COVID-19 spreads rapidly in most groups, but new research suggests that schools and day care centers appear to be the exception.

Among those under 18, the virus is easily spread by close contact with family members who have COVID-19 and at gatherings where people don't wear masks, but going to school wasn't linked to positive COVID-19 tests, according to the researchers.

You might want to think twice before you enter a hallway with strangers during the pandemic: Researchers report that following a fast-walking person with COVID-19 down a narrow corridor could increase your risk of infection, even if you keep your distance.

That's because that person can leave long streams of virus-laden droplets behind them, according to a study published Dec. 15 in th...

While loss of smell is a symptom of COVID-19, don't panic -- there are a variety of other possible causes, one expert says.

"It can be due to nasal or sinus inflammation, or other viral infections distinct from COVID-19," explained Dr. Bobby Tajudeen, director of rhinology, sinus surgery and skull base surgery at Rush University Medical Center in Chicago.

"And it can even occur as ...

Old age and chronic health conditions aren't the only risk factors for serious COVID-19 infection. Researchers say people with high levels of the heavy metal cadmium may also have higher odds of severe disease during the pandemic.

Cadmium is found in cigarettes and in contaminated vegetables. Previous research has shown that long-term exposure to cadmium, even at low levels, may weak...

As America rolls out a nationwide coronavirus vaccination campaign this week, experts help answer your questions about the new COVID-19 vaccines.

"Sickle cell disease patients should...

Humans, ferrets, cats, civets and dogs are the animals most susceptible to infection with the new coronavirus, researchers say.

The analysis of 10 species also found that ducks, rats, mice, pigs and chickens were less or not susceptible to SARS-CoV-2 infection.

"Knowing which animals are susceptible to SARS-CoV-2 helps us prevent building up animal reservoirs from which the coronavi...

Republicans have downplayed the importance of masking and social distancing throughout the COVID-19 pandemic, and a new study shows that message has filtered down to the party's youngest voting members.

Nearly one out of every four young adults from the Los Angeles region who identify as Republicans said they do not regularly follow social distancing guidelines, according to a report publ...

Having depression during childhood or in the teen years appears to increase the odds of illness and early death later on, researchers say.

The new long-term study included nearly 1.5 million Swedes. Of those, more than 37,000 were diagnosed with depression at least once between the ages of 5 and 19 years.

The study participants were followed for 12 years. Those with an early history...

More than 15 million Americans have been infected by the COVID-19 virus, and many may be questioning whether they need to receive one of the two coronavirus vaccines now on the verge of approval from U.S. regulators.

A self-collected saliva sample is as good at detecting COVID-19 as a nasal swab administered by a health care worker -- without exposing medical staff to the virus while collecting the sample.

"The current pandemic has placed a significant strain on the supply chain, from swabs to the personal protective equipment [PPE] health care workers need to safely collect samples," explained lead i...

AstraZeneca's COVID-19 vaccine is safe and effective, new data from late-stage trials shows.

Overall, the vaccine protected against symptomatic disease in 70% of cases, according to a team led by researchers from Oxford University in England. Among study volunteers who got a half dose and then a full dose, the rate was 90%, while the rate was 62% in those given two full doses.

A stronger immune system and healthier blood vessels are among reasons kids are less likely than adults to have severe COVID-19, according to experts who reviewed research from around the world.

"Most children with COVID-19 have no or only mild symptoms, most commonly fever, cough, sore throat and changes in sense of smell or taste. Even children with the usual risk factors for severe inf...

Traveling in a car with another person during the pandemic? Certain key steps might cut the odds of coronavirus spread during the trip, researchers say.

  • The number of confirmed COVID-19 cases in the United States is likely to nearly double before President-elect Joe Biden's inauguration, researchers warn.

    Cases could rise from 11.4 million to 20 million by the end of January, according to a study published Nov. 23 in the journal Scientific Reports. Of course, counts vary day to day -- as of Tuesday, for example, there were 12.4 m...

    People infected with the new coronavirus are most contagious in the first week after they develop symptoms, which shows the importance of identifying and isolating infected people early, researchers say.

    They reviewed 79 studies and clinical trials, including 73 that included hospitalized COVID-19 patients only.

    SARS-CoV-2 viral load appears to peak in the upper respiratory tract --...

    Children should be included in COVID-19 vaccine trials at the earliest possible stage, a leading group of U.S. pediatricians says.

    If that's not done, youngsters' lives could be at risk, according to the 67,000-member American Academy of Pediatrics (AAP).

    "If we do not add children to these research trials very soon, there will be a significant delay in when children are able to ac...
