"Razor blade throat" is one of the symptoms connected to a new COVID-19 subvariant called "Nimbus" that is spreading across California.
It's now causing about 20% of new COVID-19 infections in the country and is dominant in the Northeast, where it is estimated to be the cause of about a third of new cases.
While this marks an increase of 29.6%, it is lower than the 150,650 weekly hospitalizations at the peak of the omicron wave during the 2021-22 season.
As hundreds of thousands of travelers will pass through airports this week, doctors are urging passengers to wear masks as a new variant is circulating.
The best time to take an at-home COVID-19 test may be on the fourth day of having symptoms, according to a new study.
Vaccine manufacturers have said that testing shows that their vaccines are effective against EG.5, the currently dominant strain in the United States.
