Politically incorrect but essential question that must be answered. Do Caucasians and Africans have the same rate of infection, the same degree of illness if infected and death rate as is being observed in genetic Asians? Thus far the answer appears to be no.
Pretty much.
I think it is clinically way too early to tell. Much of the issue is contagion in the area. China and cruise ships are on top of each other.
The US is not. Italy is not. People get pretty close in mosques.
Hygiene is a HUGE factor. Personal space and hand washing is a HUGE factor.
Usually these numbers are not calculated in peer reviewed situations until AFTER the epidemic has ended.
I am not suggesting any of this information is disregarded—I am suggesting it should be looked at in context to how this stuff is done in other epidemics.
