H7N9 snapdate: epidemic curve as Wave 2 looks to be ending...

Click on image to enlarge.
This image is another way of showing that the current wave of human cases of avian influenza A(H7N9) virus is ending and that we are solidly within a period of "tailing" (cases only ticking over at low levels in the lead-in or lead-out of the main peak).

BUT: These data are based on figures that are publicly available. As we learned overnight, those numbers can come in fits and starts, if at all. The addition of a large number of deaths without any identifying information linking to the case onset, supports what some have been suspecting for a while; we don't have a full picture of what's happening with H7N9. 

There are now up to 48 more deaths due to H7N9 infections, depending on where your base count is taken from (verified updates or or the media) than we knew about 12-hours ago.

More on that topic later today.
