From early on, and is being studied, is genetic predisposition and when groups were last in Asia by country. East Asians coevolved with similar viruses and are least vulnerable overall because the genetically vulnerable died centuries ago. Next are central Asians. Turks and Slavs who left Asia 1000-1500 years ago are more vulnerable. Then comes Germans and Huns who left Asia 1500-2000 years ago. More vulnerable still are the Celts and Romance who left Asia 2500-5000 years ago. The most vulnerable are Amerindians who left Asia 12000 years ago, and the African diaspora that was never there (excluding Africans themselves due to an extremely young demographic, slow penetration into remote areas, lack of testing and possibly ubiquitous hydroxychloroquine usage due to endemic malaria). The rates per million of cases and deaths in countries follow a straight line up, east to west, no matter what anybody did.
The media ignores this data because the data is racist.
