Here are 2 that I can think of:
(A) Many Chinese of older generations are notoriously stubborn, they will try to tough it out and not go to a hospital for little niggles. Going to hospital for a flu is being a chickenshit coward. Those who fell in the streets may have got hit by the flu virus rapidly ramping up, sometimes it happens in a few hours.
(B) If you followed researchers hinting about the artificial origins of the virus, usually the ACE2 receptor is discussed. East Asians have a lot more ACE2 receptors versus Caucasians I believe. There is a lot of ACE2 receptors in the lung. Also worse for smokers, and there are a heck of a lot of smokers in China. The Wuhan virus is very much more potent in binding with ACE2 versus original SARS, so it may get a better foothold among East Asians.
