Report Says Mask Mandates Protect Kids in School Report Says Mask Mandates Protect Kids in School

COVID-19 rates among schoolchildren rose in districts after mask mandates were lifted, compared to similar districts that kept the mandate, a new study in the New England Journal of Medicine has found.

The study’s authors looked at infection rates in Boston-area school districts after Massachusetts education officials removed statewide school masking requirements in February 2022.

“What followed was a natural experiment in the impact of mask requirements, as school districts removed the requirement at different points in time or not at all. Two school districts (Boston and nearby Chelsea) retained the requirement throughout the study period,” Time wrote.

About 30% of all cases in the study period (or 12,000 cases) were due to rescinding the mask requirement. That resulted in at least 17,500 missed school days for students and 6,500 among staff, the study found.

“School districts that maintained required masking more often had school buildings in poor condition, crowded classrooms, and a higher proportion of individuals more vulnerable to harmful health outcomes, including those with disabilities, than the more affluent districts that lifted mask requirements,” Time reported.                 

The findings challenge the assumption that richer areas can unmask more readily because of lower transmission risk and higher vaccination rates, Time said. Cases increased substantially among schools that removed the mask requirements, including some that were “structurally more prepared to avoid and mitigate disease.”
