"New studies show that masking in public schools does help to slow the spread Covid.

Now a research paper details a so-called natural experiment that occurred when all but two school districts in the greater Boston area lifted mask requirements in the spring. Researchers took that opportunity to make a direct comparison of the spread of COVID in masking and nonmasking schools.

The bottom line: Masking mandates were linked with significantly reduced numbers of COVID-19 cases in schools.

Infection rates were lower among masked students — even in Boston’s public schools, where many buildings are old and lack good ventilation systems, classrooms are crowded and students are more often from at-risk communities — than among unmasked students attending newer schools in communities like Cambridge and Newton."
