I wouldn't focus much on the Wuhan story, as their numbers can't really be trusted much one way or the other. The story out of Bergamo is a lot more interesting, and the methodology - matching up normal death numbers with recorded numbers of deaths this year, and comparing that to the increase expected due to Covid-19 - seems legit. I'd like to see more examples of that e.g. from the UK though before I'd accept this translates to generally much higher death numbers though.

These are words of Bergamo's mayor (city with most infected and deaths in Italy)
