Los Angeles Public Well being stated there’s no indication that more moderen variants are susceptible to spreading sufficient to transform dominant variants, however the county remains to be carefully tracking a brand new BA.4.6 subvariant which has accounted for fewer than 10% of COVID-19 instances. The classification for the variant remains to be regarded as to be of low fear.
