“You could have decreases in instances and deaths while you put on masks, and you’ve got will increase in instances and deaths when you’ve got in-person restaurant eating,” Dr. Rochelle Walensky, the director of the C.D.C., stated on Friday. “And so we’d advocate for insurance policies, actually whereas we’re at this plateau of a excessive variety of instances, that may hearken to that public well being science.”
The findings come as metropolis and state officers nationwide grapple with rising strain to reopen faculties and companies amid falling charges of latest instances and deaths.

Within the newest examine, C.D.C. researchers examined the affiliation between masks mandates and indoor or outside restaurant eating and the variety of coronavirus infections and deaths final yr between March 1 and Dec. 31.
