This comes as health officials are warning of concerning weeks ahead as two new ultra-contagious Omicron subvariants — BA.4 and BA.5 — spread. Ventura County on Thursday became the first Southern California county to enter the high COVID-19 community level since the first Omicron wave faded. Two-thirds of California’s counties are in the high COVID-19 community level. Throughout late March and all of April and May, not a single California county was in the high COVID-19 community level. Los Angeles County has so far remained in the medium COVID-19 community level, where it has been since mid-May.
