I will just point out that in Sweden kids has been going to school and not much social distancing has been done to the between kids interactions. We know from statistics
that teachers have been less infected then other categories so I think that closing the school is not needed. It's strange as I would expect schools all over the map to have
problem with corona, After this time we just had a handful problematic cases and there it is unknown if it was due to the kids. Kids has also interacted freely between them
after school.
