The risks of unvaccinated unmasking
A detailed new study from the C.D.C. found that an unvaccinated elementary school teacher in Marin County, Calif., spread the coronavirus to half of her 24-student class in May and June when she lowered her mask to read aloud, in violation of the district’s rules.

Twelve of her students, who were masked but too young to be vaccinated, subsequently contracted the virus. The Delta variant outbreak subsequently spread to at least 26 people.
“I thought I respected its contagiousness,” Dr. Lisa Santora, deputy health officer the Marin Health and Human Services and an author of the report, said of the Delta variant. But its efficiency in overtaking the classroom “surprised and humbled” her.
