On Friday, all but three counties in the state had high community transmission. In mid-August, eight of 14 counties were at high risk.

The CDC wants anyone in counties with high or substantial risk to wear masks indoors, regardless of their vaccination status. That means the CDC currently recommends everyone in Massachusetts wear a mask indoors.

The CDC’s transmission data is a combination of new cases by population and positivity rate.
