https://www.sciencealert.com/paper-suggests-certain-blood-types-might-be-slightly-more-susceptible-to-covid-19

From article:

The study was undertaken by Chinese researchers and focused on 2,173 patients with COVID-19 from three hospitals in Wuhan and Shenzhen.

The team looked at the distribution of blood types in the normal population in each area, and then compared it to their sample of patients with the virus, again in each area.

"Meta-analyses on the pooled data showed that blood group A had a significantly higher risk for COVID-19 compared with non-A blood groups," the researchers write in their paper.

"Whereas blood group O had a significantly lower risk for the infectious disease compared with non-O blood groups."

But the paper also clearly states that although the results were significant, it's not an all-or-nothing result.

As per the study, the normal population in Wuhan has a blood type distribution of 31 percent type A, 24 percent type B, 9 percent type AB, and 34 percent type O.

Those with the virus, by comparison, were distributed as follows: 38 percent type A, 26 percent type B, 10 percent type AB, and 25 percent type O. Similar differences were observed in Shenzhen.
