What is it about?
SARS-CoV attaches to human angiotensin-converting enzyme 2 receptor with the spike protein and infects cells. It can play a direct role in infection by acting as a receptor and/or co-receptor for blood group antigens, microorganisms, parasites, and viruses. We aimed to compare the blood group distribution of patients with SARS-CoV-2 infection admitted to hospital and that of healthy donors. Our results are in agreement with other studies suggesting that blood group O individuals are somewhat more resistant to clinically overt infection with SARS-CoV-2 than other blood groups. However, this tendency is not sufficiently established to allow special prophylaxis recommendations for non-O individuals.

Why is it important?
The blood group distribution in our region has been determined by endemic malaria infection throughout history.Therefore, SARS-CoV-2 infection is of particular importance for this region.
Perspectives
This post was exciting for me. We were wondering whether SARS-CoV2 infection has an affinity according to blood groups in the blood groups and/or hemoglobin structure determined by the endemic malaria infection throughout history in our region. We found that the results were similar to the literature.
