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.
God knows why, but the serology cult went off into left field very early in this process. No one rational has any idea why Case Fatality Rate got renamed Infection Fatality Rate, but that’s the direction the serology cult went.
Patients who test positive are a case. The test is the PCR. There is no guessing and extrapolating. It’s not rocket science.
CDC originally said two consecutive negative tests were required to declare the patient “RECOVERED”. That loosened recently. Now it is 2-3 weeks after a positive test is RECOVERED, provided there is no additional data. It could be sooner with additional data. But in general, cases that don’t die and aren’t in the hospital are RECOVERED based only on calendar now. It’s probably a legit change.
Since testing stabilized in numbers/availability, the case numbers mean more now than they did. The US is upticking cases, and death count per day is somewhat flat over the past week or so. Europe has had a far more severe case surge, including Sweden. Their case count looks about 1/2 of the max number of June and rising.
It’s about 6 months since the arrival in Europe. Immunity is fading.
