If you go to the BNO.com tracking map they break out China by provinces. Hubei which includes Wuhan is at the top of the list. Not sure if you will be able to calculate anything but a deaths/cases ratio.
Surprisingly, the US mortality rate is 863.8 per 100k per year.
I think the numbers, especially from Hubei, are meaningless, except I suppose as a floor.
If we were dealing with what they are over here, we wouldn’t have meaningful numbers, either.
