That's interesting. I'm in California, and I know a lot of kids that have caught it, but only 2 that can trace it back to the classroom.

We have caught about 3 things over the past ~year, but none of it covid (as far as tests showed) and all of them had obvious non-classroom links.

Two of them were sick friends. And the third was probably when our 3 year old licked a trashcan at the zoo.
