A high percentage of those fatalities are from within China. Hubei Province in particular. One reference noted a HIGH prevalence of smoking within that population. If that holds true you're looking at patients with emphysema and/or chronic bronchitis to some degree. Meaning, that group is high-risk, for respiratory complications, due to pulmonary status. In fact, one reference noted an unusually high death rate among men in the 40's which they attributed to smoking/pulmonary disease within that group. They also noted women in the same age group same population fared better, they may have better genetics, so there's a lot of speculation going around. I'm working right now. If I can track the article down I'll post it.
Point is, there is good data out there but one really has to sift through it. Reminds me of the telephone game when we were kids. He said, she said, etc. Stick to good references and the picture is much more clear (IMHO). Some examples: Lancet, New England Journal of Medicine, CDC, WHO.
Just because the Chinese population, more so their social history, puts them at high-risk, doesn't mean we can generalize that data to the masses. The bulk of the fatality sample size is from China. It's a piece of the puzzle no question. However, we can safely conclude those with pulmonary conditions are at a much higher risk than those without.
