There was a report Chicago schools were closed for several days at the end of August. They said a respiratory virus was going around, I think. I don't have a link for that but here is a link to a post made here about schools in Kentucky and Texas closing for a few days. https://greatawakening.win/p/16c2W7oacH/school-classes-in-canceled-kentu/c/
I haven't dug into it, but I'm not seeing schools in the U.S. being closed down.
Nor in England
