Do you have a source for your 99% stat? I have not seen any victim racial data published.
While it is certain that more Chinese have died from this than any other ethnicity, that might just be because this thing is going on in a place mostly populated by Chinese...
It seems to have a healthy appetite for Koreans, Japanese, Iranians and Italians.
Koreans are descended from Han Chinese and Japan are closely related and Iran is just close. In any sizable group, there will be people who have genetic markers that are similar to other groups.
It’s possible that the reason why it’s infecting the rest of the world at a slower rate is because the most virulent aspects of this viruses have been contained by the trading of genetic information.
I don’t see it as a problem for myself to be worried about.
