SARS-COV-2

“There’s not anything we can do to vaccinate against this.”

No one knows exactly what this will look like—only that it’s guaranteed to keep happening.

Respiratory-virus season starts basically tomorrow, and our autumn vaccine strategy is shaky at best.

The endless churn of variants may not stop anytime soon, unless we do something about it.

If Americans decide too soon that it is over, it could paradoxically drag on even longer.

Once in short supply, rapid antigen tests are now available throughout the U.S. Boy_Anupong/Moment via Getty ImagesAs of May 2022, the U.S. is experiencing another uptick in the number of COVID-19 cases. High rates of infection in Europe and Asia, along with the continued emergence of new sub-variants, such as omicron BA.4 and BA.5, raise concerns that another surge could be on the way. Even though demand for COVID-19 tests greatly overwhelmed supply earlier in the pandemic, rapid home tests are

The U.S. will have to decide soon whether to bet big on an Omicron vaccine.

The company says a low-dose version of its vaccine triggers an immune response in children ages 6 months to less than 6 years equivalent to what has protected older children and adults.

More than two years into the COVID-19 pandemic, most Americans have some immunity against the virus — either by vaccination or infection, or a combination of both. But there have been some rare cases in which certain unvaccinated people seem to have been able to dodge the virus despite being repeatedly exposed to it. This has raised the question of whether it is possible that some people are simply immune or resistant to COVID-19 without having had the virus or a vaccine.

The Centers for Disease Control and Prevention and World Health Organization are investigating unusual cases of severe hepatitis in otherwise healthy children in the U.S. and Europe. CBS News’ chief medical correspondent Dr. Jon LaPook joins “CBS Mornings” with the latest on the investigation.

My 6-year-old has been exposed to SARS-CoV-2 at least 4 times and never tested positive. Lots of people fall into that category. Researchers have theories about why they've been able to ward it off.

New virus variants evolve to evade hosts’ immune systems. But those immune systems also keep adapting.

After a stellar run in adult and teen trials, the vaccines are now trying to contend with Omicron, and the numbers show it.

That's how the so-called "deltacron" variant — a mashup of delta and omicron — came to be. This process of recombining tells us a lot about the possible past and future of SARS-CoV-2.

The successes and failures of annual flu-shot campaigns hold lessons for the future of COVID vaccines.

The mystery of how SARS-CoV-2 may cause brain fog or other neurological symptoms in some people is driving new global research.Why it matters: Roughly 79 million Americans contracted COVID-19 in the first two years of the pandemic. While most survived, many are grappling with long-term symptoms, or long COVID, that affect the brain and other body systems.Stay on top of the latest market trends and economic insights with Axios Markets.

Two studies point to a link between the animals at the seafood market and the spread of SARS-CoV-2 — foreshadowed by photos from 2014 of raccoon dogs and birds. A top virus sleuth gives the details.

Cough? Test. Stuffiness? Test. Scratchy throat? Test.

The vaccines will need an update at some point. But not every variant of concern will warrant it.

Answer a few questions and find out what kind of immune cell you'd be – and learn more about these amazing cells that fight off infection.

A new study documents that infected hamsters, imported from the Netherlands, passed the virus on to humans. Previously only minks had been identified as a source of animal-to-human transmission.

Throughout the pandemic, SARS-CoV-2 has transmitted easily from humans to other species. Some scientists now believe that animals could spread new variants back to us.

The family history of SARS-CoV-2 is not what virologists expected — and sheds light on the virus that launched a pandemic. Check out our illustration of the virus' family tree.

Researchers say their test is as accurate as PCR lab tests, which are highly accurate but usually take several hours to carry out.

Scientists are beginning to come up with answers to the question of how long antibodies from an infection can protect you — and what they'll protect you from.

A shot designed for Omicron can teach the immune system about Omicron. But it might not prepare us for whatever comes next.

The coronavirus will never run out of ways to evolve, and the variant after Omicron could look very different from any yet.

But many epidemiologists are beginning to look ahead to a post-Omicron world.The pandemic experts The Daily Beast spoke to were unan

Researchers from Boston University analyzed data from more than 2,000 couples trying to conceive.

A variant that spreads comprehensively won’t necessarily protect comprehensively.

When the coronavirus attacks the body, the immune system steps up, trying to respond quickly and powerfully enough to stop the virus from running wild.

A look at the data that omicron is less severe. What does that mean for the future of SARS-CoV-2 — and the pandemic?

A new study published by researchers at Oregon State University found that hemp compounds have the ability to prevent the virus from entering human cells.

As researchers try to determine the severity of cases caused by the omicron variant, the question of what exactly constitutes mild, moderate and severe COVID is weighing on people's minds.

Just ten states have active mask mandates, despite the fact that omicron is moving in on the U.S. fast. Despite their political unpopularity, research shows masks still work and could save lives.

Gov. Ron DeSantis made some comments during a news conference Monday related to the recent resurgence in COVID-19 cases and how it's affecting hospitalizations.

GAINESVILLE, Fla. – A new epidemiological study from the University of Florida found that while children are less susceptible to COVID-19, they can be nearly 60% more likely than adults over 60 to infect exposed family members. The overall contribution of child cases to household transmission was still limited, the study determined, as children were isolated faster than adults who were infected. Older adults were more likely to become infected than younger household members, especially those under age 20. While children were less susceptible to COVID-19 infection than adults and they generally experienced less severe symptoms, they were just as likely to develop symptoms as adults. “I recommend following CDC guidelines and taking extra caution when a household or family member is infected,” Yang said.

China has stirred controversy with claims it has detected the coronavirus on packages of imported frozen food. (AP Photo/Andy Wong)BEIJING – China says it has detected the coronavirus on packages of imported frozen food, but how valid are its claims and how serious is the threat to public health? Frozen shrimp imported from an Ecuadorian company was banned for one week on Tuesday in a continuing series of such temporary bans. Experts say they generally don’t consider the presence of the virus on packaging to be a significant health risk. “I’ve seen no convincing data that SARS-CoV-2 on food packaging poses a significant risk for infection,” he said.
