We Never Know
No Slack
Revising a decision made just two months ago, the Centers for Disease Control and Prevention said on Tuesday that people vaccinated against the coronavirus should resume wearing masks in public indoor spaces in parts of the country where the virus is surging.
C.D.C. officials also recommended universal masking for teachers, staff, students and visitors in schools, regardless of vaccination status and community transmission of the virus. With additional precautions, schools nonetheless should return to in-person learning in the fall, according to agency officials.
The recommendations are another baleful twist in the course of America’s pandemic, a war-weary concession that the virus is outstripping vaccination efforts. The agency’s move follows rising case counts in states like Florida and Missouri, as well as growing reports of breakthrough infections of the more contagious Delta variant among people who are fully immunized.
“The Delta variant is showing every day its willingness to outsmart us,” Dr. Rochelle Walensky, director of the C.D.C., said at a news briefing on Tuesday.
Data from several states and other countries show that the variant behaves differently from previous versions of the coronavirus, she added: “This new science is worrisome and unfortunately warrants an update to our recommendation.”
