LOS ANGELES — Health officials are warning of a possible surge of new COVID-19 cases this fall and winter as new subvariants emerge.

The Los Angeles Times reports experts are keeping their eyes on a handful of Omicron’s subvariants. They say the number of mutations has made them much different than what we’re used to.

Anti-viral treatments have also not been as effective against some. None of these variants are circulating widely in the U.S. now.

Officials recommend getting updated booster shots.
