Los Angeles County raised its Covid-19 alert level, responding to surging cases of omicron subvariants BA.4 and BA.5.

The most-populous US county on Thursday bumped up its warning level to “High” from “Medium” after flagging the surge in cases earlier this week. Hospital admissions have surpassed 10 per 100,000 residents over a seven-day period, officials said Thursday, an 88% increase from a month ago.
