My understanding from everything I have read and heard is that infection is completely indiscriminate regarding ethnicity, gender, make of shoes, colour of clothing, etc., even age as well, all of this in equal conditions of exposure - everyone is infected to the same likelihood when exposed to the virus. It is widely believed that infection affects the young less severely and that in the general population perhaps as many as 50% of those infected (all ages perhaps) never get any symptoms. However, there is evidence, at least in the USA, that ethnicity matters when it comes to how badly the illness affects people. The statement I came across somewhere recently was that in the USA the ethnic minorities tend to be poorer, less well nourished (quality of diet), more overweight, more likely to have diabetes, etc., etc. In other words, that they are less fit to fight off the infection, that they therefore become more ill and consequently are more likely to die as a result. This may well be similar elsewhere, not so much an ethnic predisposition but one by lifestyle and in particular lower income and/or poverty.
