Kids in classrooms is probably the safest place they can be as it is a fairly controlled environment. What I was trying to say is that when the kids leave school all bets are off. Even if we assume kids won't suffer greatly when they're infected, they still are imminently capable of spreading the virus wherever they go and to whomever they come into contact.
One of my kids knows a family that has been exposed to the virus and been notified of that fact; I think they call that "close contact". That family did not get tested, and instead of quarantining as suggested, spent a weekend on the road, visiting neighboring communities and attractions. And on Monday morning they sent the kids to school.
If those kids are carrying the virus, they spread it all over southern North Dakota and northern South Dakota, at playgrounds, cafes, etc. And then went back to school and after school daycare, potentially spreading to yet another population.
Clearly this family is ignoring the risks (or just plain ignorant). They're acting selfish to say the least.
Students wearing masks in a classroom are helpful. However, many rural schools aren't requiring students to wear masks at lunch, in the hallways or at recess. Heck, one of my kids teaches in a district where the school board refused to mandate masks anywhere.
But if some families refuse to recognize the risk, or the benefit of limiting exposure after school and on weekends, the virus will continue to spread unchecked.
I don't want school kids to be infected. But I also don't want them turning into super spreaders simply because they are asymptomatic and their parents are foolish.
