Weird Epidemiological Science

Lucianne.com links to New York Post article which reports preliminary findings from China to the effect that people with type A blood appear to be more likely to come down with Covid-19 whereas people with type O blood appear somewhat less likely. The differences are neither huge nor absolute but nevertheless real.

The study also examined 206 patients who died from the virus, finding 85 victims, or 41.26 percent, had type A blood. Just 52 of the deaths, or about a quarter, had type O.

For comparison, around 48% of the Chinese population has type O blood and 29% has type A.
