Officials say it appears L.A. County has passed the peak of the omicron variant surge, but cases of a new subvariant have been detected.
LOS ANGELES -- While the winter surge of COVID-19 infections fueled by the Omicron variant appears to be easing, authorities are watching the emergence of an omicron"sub-lineage" that has spread rapidly in some countries, with Los Angeles County's health director saying four cases have been recently found locally.
"We don't yet know how BA.2 might be different than other omicron lineages, and scientists will be working rapidly in the coming weeks to learn more about immune evasion, severity and transmissibility," Ferrer said."In places that have already passed their peak of omicron cases, it does appear that BA.2 is causing a new surge. In places at their peak of the omicron surge that have significant BA.2 prevalence, it doesn't appear that BA.
"It's very possible there could be another variant of concern in the future that can spread easily and contribute to another surge," Ferrer said."Given the effectiveness of the FDA-authorized vaccines against at least four different known strains of the virus -- we've had alpha, epsilon, delta and omicron -- vaccines do remain our best tool for preventing COVID-19.
