Q, I believe this pneumonia graph you shared was incomplete at the time. The current data is available here:

There is no drop off

You can tell in the current data the most recent week is incomplete (drop off from 16,917 deaths to 2,214). The CDC explains this here
I am not saying the numbers are not being manipulated at all. There is a financial incentive for hospitals to do so at least in the U.S.
I am saying the pneumonia graph SPECIFICALLY, the one that Q shared, is inaccurate because the data for week 11 was incomplete at the time.
Actually this is not the latest either. This was the graph as of last week
