Are people with certain blood groups more susceptible to COVID-19 infection?

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.

Hence the study result showed that people with blood group A have a significantly higher risk for acquiring COVID-19 compared with non-A blood groups, whereas blood group O has a significantly lower risk for the infection compared with non-O blood groups but it doesn't mean that people with type O blood type are immune, and not everyone who gets the virus is going to be type A.

There are relatively small differences that stay as a major limitation of the study." If replicated in studies with larger data pools, it could lead to slight changes in the way we manage the spread of the disease; but even so, it probably won't change anything about the way we individually should be trying to limit the spread of the virus" concluded the authors.
