LANSING, Mich. (AP) — Michigan’s top doctor said Wednesday she had told Gov. Gretchen Whitmer and the state health director that reinstituting a mask requirement in K-12 schools would likely lessen the spread of COVID-19, but she added there are other factors when considering the step.

Dr. Joneigh Khaldun, the state’s chief medical executive and chief deputy health director, reiterated that she is “concerned” about the coronavirus’ potential impact on schools as the delta variant takes hold. The state Department of Health and Human Services last week strongly recommended universal masking in schools regardless of vaccination status but stopped short of requiring it.
