This is a brief COVID update. Cases have been flat in the US, California, and San Diego County, neither rising or falling. This may be partially because of the introduction of 2 new variants, BA.4 and BA.5. These new variants are both of the Omicron vintage. The good news is that deaths have not risen for many weeks even after cases rose due to the BA.2 variants.
My guess is that BA.4 and BA.5 will continue to drive new cases for a few more weeks before we start seeing cases come down. It appears that the fatality rate for these new variants is also very low when compared to other COVID variants.
The contribution BA.4 and BA.5 variants in the US is growing, as they new represent approximately 50% of the total SARS-2 viruses in the country.
