The assumption of a faster, tighter window of 'exposure to no longer contagious' may need a second look as well.
The state is not requiring masks in classrooms and very few students are wearing them. The state does not require a negative test to return after the shortened isolation (5 calendar days after positive test) or quarantine (5 days after close contact/exposure) but does require the students returning (even those who declared a positive result) to wear a mask for an additional 5 calendar days.
Declaring exposure at home or symptoms or testing results? Totally honor system. All of it. Like the virus no longer acts like a virus,
