That’s what they’re calling for, among other measures:
Working parents without child care have a legitimate concern, and we must find ways to help one another. But school closings can be the single most effective intervention. Amid an influenza pandemic, schools would be closed to protect the students themselves. Because children are not among the groups most vulnerable to coronavirus, schools should be closed in an effort to reduce community transmission and to protect the children’s parents and grandparents. How long? Epidemiologists suggest eight weeks might be needed to arrest this outbreak. Administrators, students, teachers and parents need to get busy figuring out how to continue the education of our children while contributing to this community-wide public health effort.
Then, based on the success of the closures, leave the public schools shuttered for good.
