Interesting graph from an epidemiologist.

Black bars are "influenza like illnesses" not diagnosed as the flu. In many regions, these mysterious non-flu respiratory illness ed in December/Jan at a rate about as high as past flu seasons. The encouraging thing here is that Covid has been with us since December, translating into who knows how many unconfirmed (and recovered) cases (which will significantly lower the CFR). Hopefully this could mean we're closer to herd immunity than we think (not nationwide, but regionwide) in certain regions. Obviously we'll need serological tests to confirm.
