The Center for Disease Control and Prevention data from the new K-12 school year bolster the agency’s recommendation for masks in schools and in-person classes.
One study in two Arizona counties found coronavirus outbreaks were almost four times more common at public schools without mask mandates on the first day than at those that re-opened with a masking requirement.
Another study found case rates in children and teens increased more in U.S. counties where public schools had no mask mandates than in those where schools had that requirement. These studies lacked data on other measures that could have influenced the results.
A third study counted 1,801 coronavirus-related school closures through mid-September, most of them in the South, where many schools opened earlier than those in other regions.
“Universal masking is an important component in the recommended layered prevention strategy for schools, and this study continues to demonstrate that facemasks when used as part of the larger strategy can reduce spread of COVID-19 and prevent outbreaks in schools,” the CDC wrote on its website.
Still, 96% of U.S. public schools have remained open with in-person classes, the researchers say, while acknowledging that data from some districts may be missing.
