You could follow 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 due to age demographics and possibly ubiquitous hydroxychloroquine usage due to endemic malaria). The rates per million in countries follow a straight line up, east to west.
The US case RATE of 23,165 per million (population 331 million) is exceeded, in declining order, by Qatar (45,121), Bahrain, Aruba, French Guiana, Andorra, Israel, Panama, Kuwait, Peru, Chile and Brazil (23,199) with a combined population of about 283 million. The US death RATE of 649 per million is exceeded by San Marino (1237, surrounded by Italy), Peru, Belgium, Bolivia, Brazil, Spain, Andorra, Chile and Ecuador (659) with a combined population of 350 million. The first trailing country is UK (623, UK = England, Scotland, Wales and Northern Ireland). And while the highest number of daily new cases in the US was on July 24, the highest number of new cases in the UK was YESTERDAY. In France, it was last SATURDAY (Oct. 3). (Deaths trail cases, if you don’t get the point.) Use the sortable columns: https://www.worldometers.info/coronavirus/
Here are some more data. Brazil and the US have roughly the same known infection rate per capita. The US has conducted 114 million tests to come up with 7.7 million cases, many asymptomatic, an infection rate per test of 6.8%. Brazil has conducted 18 million tests to find 5 million cases, an infection rate per test of 27.8%. For its population, Brazil has conducted 1/4 as many tests per capita. Doesn’t it look like Brazil is probably missing almost all its mild and asymptomatic cases? If Brazil had done 4X the testing and found only the US rate of 6.8% in the remainder, it would have 2/3 more cases, or a total of 8.3 million, 9% more cases in a population that is 1/3 smaller. That is one way you get the US with 21% of global cases: the US can look for and find them when most of the world can’t and doesn’t. The US has conducted 16% of global tests, 114/~700 million.
We have a new global case rate record today over 1/3 million for the first time. Russia skyrocketing again, very near a new high. UK, France, Belgium, Netherlands new highs. Germany, highest since April 9. And in places like Argentina (new high) the graph implies they have been lying about deaths for months
Deaths may trail the cases but not in the same proportions. The U.S. has had slight increases in the daily cases but the daily deaths are trending downward. That is because treatment is getting much better and, as therapy gets much better, there are fewer deaths.
