> how schools increase the spread of disease

I would want to think hard about the second-order effects of preventing transmission of regular school colds & flus before trying to suppress them, which would be that people would miss out on training their immune systems while they are young & resilient.

It would be nice to get sick less often and environmental suppression in schools seems like such an obvious win... but I don't have enough understanding to know if it would really be a good thing one way or the other.
