Is THIS Why Most Coronavirus Deaths Have Been In Chinese Men?  

Good article, but the title is misleading because it’s not really about the Chinese or men, it’s more about ACE2 (aka Angiotensin-converting enzyme 2). It happens though that ACE2 levels are higher in people who smoke and in general, Chinese men are heavy smokers, it’s a social thing. (a few years back a Chinese neighbor’s father was visiting from China and he offered me a cigarette every time we met. He just didn’t seem to understand that none of his daughters neighbors smoked.)

Not saying it’s definite, but it’s possible that high ACE2 levels form a pathway (vector?) for the virus. Don’t know, I’m not a doctor nor a microbiologist.
