While vaccination rates have plunged since the middle of April, the more contagious Delta variant has exploded.
There’s an alarming jump in cases across the U.S. New infections are up by more than 120% nationwide in the past month and the CDC director says the Delta variant accounts for 83% of infections. While nowhere near the highs of the pandemic, a fourth — and mostly preventable — wave is appearing. Across the country, vaccination rates have plunged since mid-April and the more contagious Delta variant has exploded. «CDC has released estimates of variants across the country and predicted the Delta variant now represents 83% of sequenced cases. This is a dramatic increase, up from 50% for the week of July 3. In some parts of the country, the percentage is even higher, particularly in areas of low vaccination rates,» CDC Director Rochelle Walensky said in a Senate hearing on Tuesday.
