Interesting work. Scientists attempted to find a correlation between blood type and COVID fatalities. Using small samples from three hospitals, there appears to be a somewhat elevated risk for those with Type A blood, and significantly reduced for those with Type O. In my opinion, it is too soon to draw conclusions, as the sample sizes in two of the three hospitals are quite small. Only the sample from the hospital in Wuhan is worth the time spent on this post, yet without rechecking in other locations, it is still premature to make claims. They analyzed the blood groups of 3694 residents, resulting in 32.16%, 24.90%, 9.10%, and 33.84% for groups A, B, AB, and O respectively. Among the infected, the distribution was 37.75%, 26.42%, 10.03%, and 25.80% – highlighting groups A (higher risk) and O (lower risk). Furthermore, they gathered data from 206 deceased in the same hospital. The results were 41.26%, 24.27%, 9.22%, and 25.24% – meaning, among the deceased, there was a significantly higher than average number of people with Type A blood (41.25 versus 32.16) and significantly fewer with Type O (25.24 versus 33.84).
The authors acknowledge the problem with the lack of data in two hospitals and noted the absence of information on the distribution by age and gender. It is also difficult with such small samples to account for the influence of other factors, such as pre-existing illnesses. It could turn out, for example, that patients with Type A blood are more likely to suffer from something that complicates the treatment of COVID.
