Thus far almost all the people who have contracted this virus and become ill are Asiatics. Population genetics is of critical importance in determining the virulence of a pathogen in a given area. There are many Westerners who live and work in Wusan. Have any of them become ill?
BTW this is a very politically incorrect question to ask or research. It could cost epidemiologists their funding and jobs.
