A significant number of U.S. counties are now considered as areas of 'high' or 'substantial' transmission.
Previously, the health agency had said fully vaccinated people"can resume activities that you did before the pandemic without wearing a mask or physically distancing, except where required by laws, rules, regulations, or local guidance.", and allows people to view which counties in which state are at a certain level of transmission.Others, such as North and South Dakota and Montana, are a mixture of"low" to"high" transmission counties.
Walensky said:"Information on the Delta variant from several states and other countries indicates that in rare occasions some vaccinated people infected with the Delta variant after vaccination may be contagious and spread the virus to others. "Vaccinated individuals continue to represent a very small amount of transmission occurring around the country."
CDC data also shows there were 53,772 new cases across the country on Monday, down from this month's peak of 67,023 on July 23. However, the seven-day moving average has continued to increase.
