Officials emphasized that Biden's symptoms are mild because he received four vaccine doses and started taking the antiviral drug Paxlovid after becoming infected.
The BA.5 COVID-19 strain is an offshoot of the omicron strain and is spreading rapidly right now through the United States.
Subvariants BA.4 and BA.5 are more transmissible, and early evidence shows both are capable of evading immune responses from previous infection as well as current COVID-19 vaccines.
Moderna’s study results revealed people given the combination vaccine shot had higher antibody levels to fight omicron and other variants.
While COVID-19 infections are declining, Austin-Travis County officials are still encouraging mask-wearing, social distancing, and getting vaccinated.
Experts say it's not likely that the highly transmissible omicron variant — or any other variant — will lead us closer to herd immunity against COVID-19.
This winter's omicron wave in the U.S. also bolstered our defenses, leaving enough protection against the coronavirus that future spikes will likely require much less disruption to society.
U.S. health regulators on Friday authorized bebtelovimab, a new antibody drug that targets the omicron variant, a key step in restocking the nation's arsenal against the latest version of COVID-19.
Experts say it's too early to know whether people infected with the omicron variant will develop long COVID. Doctors believe it's possible to have long-term effects from omicron.
Propelled in part by the wildly contagious omicron variant, the U.S. death toll from COVID-19 hit 900,000 on Friday, less than two months after eclipsing 800,000.
With the brutal omicron wave rapidly loosening its grip, new cases of COVID-19 in the U.S. are falling in 49 of 50 states, even as the nation's death toll closes in on another bleak round number: 900,000.
Spain will end a mandate to wear masks outdoors next week, reversing a late December order against an unprecedented surge of coronavirus infections fueled by a highly contagious mutation, Health Minister Carolina Darias said.
Omicron's race across the globe has amped up concerns about long COVID, which some estimates suggest affects a third of COVID-19 survivors.
The new omicron variant BA.2 has been detected in Wisconsin, according to a tweet from Dr. Ben Weston, Chief Health Policy Advisor for Milwaukee County.
The daily count of new coronavirus infections in Russia spiked above 110,000 as the highly contagious omicron variant races impacts the country.
The new coronavirus variant, which scientists call BA.2, is widely considered stealthier than the original version of omicron because particular genetic traits make it somewhat harder to detect.
The California Department of Public Health confirmed that there are 11 cases of the new omicron subvariant in the state.
It may be hard to believe, but there is such a thing as too much meat.
U.S. health officials say COVID-19 antibody drugs from Regeneron and Eli Lilly should no longer be used because they don't work against the omicron variant.
Pfizer has begun a study comparing its original COVID-19 vaccine with doses specially tweaked to match the omicron variant.
