With so many teens not vaccinated, why are the schools not notif

Villas - With so many teens not vaccinated, why are the schools not notifying parents about the cases in our neighborhood schools? Why is CMC so secretive about letting parents know about covid cases? We are not asking names? My kids are vaccinated except for the youngest child but we do have teens that come to our home and socialize.But you can't expect all parents to get their kids vaccinated.Why I don't understand because they can go to Walgreens and local community centers and get tested.They even sell kits too if you want to test yourself or you kids.Can you imagine refusing a polio vaccine?
