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.
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.
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...
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.
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.
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.
As the new coronavirus rages across the country, President-elect Joe Biden has set a goal of one million doses of vaccine delivered every day once he takes office. If that ambitious target is realized, everyday conditions in the United States might ...
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 knownU.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...
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.
In very rare cases, some people have had severe allergic reactions after receiving the new COVID-19 vaccines, leading the American College of Allergy, Asthma, and Immunology (ACAAI) to issue updated guidance for Americans with allergies.
The U.S. Food and Drug Administration has given emergency use authorization to COVID-19 vaccines from Pfizer-BioNTech and Moderna.
There's a lot of misinformation about vaccines as the United States begins its massive COVID-19 vaccination program, so an expert wants to dispel the many myths about vaccines in general.
Vaccines are among the most heavily studied of all drugs, and the evidence shows they are safe and extremely effective, according to Dr. Patrick Gavigan, a pediatric infectious disease physician at Penn ...
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.
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.
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.
Both the Pfizer vaccine (already approved by the U.S. Food and Drug Administration) and the Moderna vaccine (up for approval) were developed using a technology called messenger RNA, or mRNA, explained Dr. Thomas Ma. He's chair of the department ...
The first non-prescription COVID-19 test that enables people to collect samples and get results at home has received emergency use authorization from the U.S. Food and Drug Administration.
"This is a great step forward," said Dr. Amesh Adalja, senior scholar at the Johns Hopkins Center for Health Security, in Baltimore. "If people could know their status on any given day, they could chang...
Two new COVID-19 vaccines, developed at record-setting speed, are soon to be assessed by U.S. agencies for emergency use in combating the ongoing pandemic.
Advisory panels of infectious disease experts this week will assess a vaccine developed by pharmaceutical company Pfizer and German biotech firm BioNTech -- a vaccine that Britain began administering to its most vulnerable citizens on ...
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.
Scientists say they may be getting closer to creating a universal flu vaccine.
In an early-stage clinical trial with 65 volunteers in the United States, an experimental vaccine triggered strong immune responses to a wide range of flu virus strains and subtypes. The immune responses lasted at least 18 months, according to the researchers at Mount Sinai Health System, in New York City.
Approved vaccines against the new coronavirus could begin to be distributed to the most at-risk Americans as early as mid-December, Dr. Anthony Fauci, the nation's top infectious disease expert, said Thursday.
"And as we get into the first quarter of 2021 — January, February, March — more and more people will get vaccinated," he added in an
The antiviral drug remdesivir is not recommended for hospitalized COVID-19 patients because there's no evidence that it reduces their need for ventilation or improves their chances of survival, a World Health Organization panel said Thursday.
Remdesivir is regarded as a potential treatment for severe COVID-19 and is used to treat hospitalized patients, but there is uncertainty about its e...
A deadly South American virus that causes Ebola-like bleeding can spread human-to-human, public health officials have learned from its second-ever outbreak.
Public health investigators have reconstructed the path by which the Chapare virus spread from person to person during a 2019 outbreak in Bolivia, leaping from the initial patient to several health care workers.
When Ebola virus outbreaks occur, people's exposure may be more widespread than realized, according to new research. It found antibodies for the virus in people up to a year before the 2018 outbreak in the Eastern Democratic Republic of Congo.
That suggests either that early cases were missed or that exposure was more common than previously known, according to researchers at the Universit...
Most kids infected with COVID-19 who don't have symptoms have low levels of the virus, compared with symptomatic children, a new study finds.
Researchers said it's not clear why.
"While these findings provide some reassurance about the safety of asymptomatically infected children attending school, these unanswered questions suggest that risk mitigation measures in day cares, schools...
The COVID-19 pandemic is taking a significant toll on New York City transit workers, who are grappling with illness, anxiety and the loss of colleagues.
About 24% of transit workers who participated in a pilot study led by New York University researchers reported having had COVID-19. About 76% said they knew a colleague who had died of the disease and 90% feared they also would get sick.<...
When adults with Down syndrome contract COVID-19, their risk of dying is much higher than the norm, a large, new study finds.
The researchers found that of over 8 million British adults, those with Down syndrome were four times more likely to be hospitalized with COVID-19, and 10 times more likely to die due to the infection.
Right now, people with Down syndrome are not incl...
Factors such as sex, age and severity of the disease may help identify COVID-19 survivors who have high levels of antibodies that can protect against the disease, a new study suggests.
"These were significant patient characteristics that not only predicted the amount of antibody but the quality of that antibody," said lead author Sabra Klein, a professor in the Department of Molecula...
