I saw this on The Guardian – Delta variant accounts for 83% of new cases in US, CDC director says: https://www.theguardian.com/us-news/2021/jul/20/delta-variant-us-covid-increase-cdc-director. Longer article, but here are some basics.
The highly transmissible Delta variant of the coronavirus now accounts for 83% of all sequenced cases in the US, a top federal health official said on Tuesday.
“This is a dramatic increase, up from 50% [in] the week of 4 July,” Rochelle Walensky, director of the Centers of Disease Control and Prevention (CDC), said in Senate testimony.
Walensky also said Covid fatalities had risen by nearly 48% over the past week to an average of 239 a day.
