New omicron subvariant is taking hold in the United States, health officials say, though it does not look more severe than its predecessors.
MONDAY, Nov. 28, 2022 (HealthDay News) – U.S. health officials are tracking a new COVID variant that's a combination of two earlier Omicron subvariants.
A new coronavirus variant called XBB is marching up the CDC's watchlist and has become a variant of concern.
XBB has been on the CDC’s radar since earlier this month, when it first began doubling its case counts every 12 days. It is a combination of two Omicron subvariants (BA.2.10.1 and BA.2.75) first seen in September and is among a growing group that could render some antibody treatments ineffective.
The Centers for Disease Control and Prevention revealed Friday it is now tracking a new COVID-19 variant of concern around the U.S. known as XBB, which has grown to make up an estimated 3.1% of new infections nationwide.
