LOS ANGELES — After dramatic declines in coronavirus cases, Los Angeles County has hit another plateau this week that comes amid the spread of the highly infectious BA.2 omicron subvariant.
BA.2 has led to new increases in cases in other areas, from a significant surge in Britain that has resulted in an increase in hospitalizations and deaths, and the apparent beginning of a wave in New York and Massachusetts.
Similar trends have not yet been seen in Los Angeles County or in California overall, and officials can’t say with certainty what will come next.
