As states roll back masking requirements for students, a new study shows that masks helped cut Covid-19 infections in public K-12 schools that required them in the fall.

The study comes from a partnership between the US Centers for Disease Control and the Arkansas Department of Health. Investigators looked at Covid-19 infections in Arkansas schools over a period of about seven weeks from August to October 2021, when the Delta variant was the major cause of infections. The study was published Tuesday in the CDC's Morbidity and Mortality Weekly Report.

Overall, schools that required masks had 23% fewer Covid-19 cases on average than those that didn't.

"This is a valuable finding consistent with other past data during the Delta wave," Kristen Nordlund, a CDC spokesperson, said in an emailed statement.
