Hmm, the flu is “back”.
I find it particularly interesting that cases of flu dropped something like 97% in 2020. (Sorry for Yahoo link.) Gee, where did all those flu cases go, one wonders?

Even **I** can see that something is very wonky there. It just doesn't GO from millions to a tiny number in one year.
