2019-nCoV targets ACE2 receptor cells in the lung. Current estimated death rate is 15% (based on now slightly out-of-date Lancet articles). Asian men are the most susceptible group. Male / female infection rate currently about 3:1 (but based on low statistics). Ratio of ACE2 cells in Asian men to Asian women is about 4:1. Ratio of ACE2 cells in Asian men compared to whites or African-Americans is 5:1. https://www.biorxiv.org/content/10.1101/2020.01.26.919985v1.full https://www.biorxiv.org/content/10.1101/2020.01.26.919985v1.... See some criticisms of the methods and results in the comments. Interesting correlation of ACE2 to stress and high blood-pressure, so could be strongly affected by some treatments for hypertension. It is just about possible, in some qualitative hand-waving way, that reducing susceptibility by 80% could drop R0 from 5 to 1, hence reduce the threat of an epidemic in other regions.
