We are seeing +100k #COVID19 cases per day in the U.S. Last week, over 99% were #DeltaVariant. At least 19 states have confirmed cases of #OmicronVariant. We must act together to address current cases and prepare for the possibility of more Omicron https://t.co/3ln8b8QlAD. pic.twitter.com/jNBdMicv1i
