More than 98% of US residents now live in an area where there is a "high" or "substantial" risk of Covid-19 community transmission, up from 19% of residents only a month ago. This sharp turn has been driven in large part by the highly infectious Delta variant and low vaccination rates in many regions.
The latest figures from the Centers for Disease Control and Prevention show an alarming rise in the number of counties that are considered at high risk of community transmission. On Monday, 2,361 counties in the United States were listed in the "high" tier, a stark increase from 457 counties in the same tier at the beginning of July.
A look at the past five weeks shows just how rapidly community transmission has increased across the country.
