A boardwalk pizza place with takeout only closes to clean due to

Middle Township - A boardwalk pizza place with takeout only closes to clean due to three employees testing positive. Now a local restaurant with outdoor dining closes for cleaning due to one employee testing positive. My question is what is going to happen when a student or teacher test positive when schools reopen. Will schools be required to close for cleaning? My guess is yes ,so us parents all need to have back up plans for when this happens.
