Summary statement
What is already known about this topic?
There are some studies examining the relationship between Covid-19 and blood groups in the literature. It has been found that the rate of infection with SARS coronavirus is lower in blood group O.
What this paper adds?
Our study showed that there was a very significant increase in the number of individuals with blood type A in Covid-19 patients compared to healthy individuals, almost a significant increase in the number of AB blood group Covid-19 patients with blood group AB, and a very significant decrease in the number of Covid-19 patients with blood group O
The implications of this paper:
Our study has found that having blood group O may be protective, that blood group A may have a greater susceptibility to the disease, but this does not affect the course of the disease and is not associated with mortality. We want to emphasize that the most important and easiest way to avoid Covid-19, regardless of the risk factor and the facilitating factor, is to maintain social distance, hand hygiene, and use of.
