A cluster of midwestern and southern states have emerged as new hotspots for Covid

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.

“Each death is tragic and even more heartbreaking when we know that the majority of these deaths.”
