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.
