When the blood groups of patients diagnosed with Covid-19 and the control group were compared, there was an increase in the number of patients with Covid-19 in blood groups A and AB, a decrease in blood group O, and it was similar in blood group B and Rh. The statistical analysis showed that there was a very significant increase in the number of individuals with blood group A in Covid-19 patients compared to healthy individuals, and almost a significant increase in the number of Covid-19 patients with blood group AB and a very significant decrease in the number of Covid-19 patients with blood group O, and no significant difference in terms of B and Rh blood group system (Table 1).
