Cambridge issues mask advisory, as COVID cases rise

Cambridge is once again urging residents to wear masks while indoors, in response to the current high level of COVID transmission.

The city issued the mask advisory on Monday. And while it doesn't go as far as previous mandates, city officials are "strongly recommending that residents wear masks when indoors outside the home and when around others."

Cambridge also announced that it would expand its free COVID testing program with an additional walk-in site.

On the same day, Brookline reinstated a mask mandate for town-owned buildings, including public schools and libraries.

The Centers for Disease Control and Prevention have designated a number of counties in the region as high-risk areas for COVID transmission, as cases have once again been on the rise.
