Blood Types and COVID Response

Studies have shown that those with type A and AB blood have been found to have an increased risk of contracting COVID compared to someone with type O or B blood. This theory has been supported based off of statistical data which describes number of positive COVID cases and severity across the various blood types. It has been found that those with type A or AB blood run a higher risk of infection than type O or B.  

This idea cannot be used to allocate how the population should consider precautions however. This theory although is interesting in tracking risk, could prove to be detrimental to ultimately gaining control of the rate of infection. If the knowledge that type O and B persons are at a lesser risk of contracting COVID, they could potentially loosen their constraints on recent social restrictions and proper masking.




  1. You learn something new everyday, I did not know if you have a certain blood type it can increases your chance of getting covid.

  2. This is very interesting. I would love to see near-future research on whether or not hemoglobin has an impact on vulnerability, as well as specific experiments using the various antigens respective to each blood type in order to isolate the mechanisms involved with increased/decreased vulnerability.

  3. I have also heard about the relationship between different blood types and COVID response. It seems so odd that something like what type of blood you have can affect the likelihood of getting a virus. I have made some connections with my own experiences with COVID that make sense with the information in this article.
