Özet

Aim: Since blood types first appeared, their association with diseases caused by microorganisms has\rbeen further investigated with several studies for many years. The bond of blood groups described as A,\rB, AB, and O with coronavirus has been the research subject in many countries.We aimed to elucidate\rwhether there was a relationship between blood types and Rh factor and contracting COVID-19 disease\rand disease severity.\rMethods: The study was designed as a retrospective case-control study. Between March 2020 - February\r2021, 1110 patients were included (538 cases, 572 controls). Disease severity was classified according\rto where patients were treated: those who were outpatients considered as “mild disease´, hospitalized in\ra hospital ward considered as “moderate disease´, and treated in the intensive care unit were considered\ras “severe disease´.\rResults: The number of people with blood type A was 447 (40.3%), blood type B was 197 (17.7%),\rblood type AB was 90 (%8), and blood type O was 376 (33.9%). There was no significant difference\rbetween the case and control groups according to the blood types. A 3.93 times increase of developing\rmild illness was detected compared to the control group in Rh-positive individuals. The rate of\rdeveloping a severe disease was higher in females with blood type A than a mild disease, and A blood\rtype caused the disease to be severe compared to other blood groups in females.\rConclusion: We concluded that blood type A caused more severe disease than other blood types in\rfemales, and females with B blood type survived the disease as outpatients. Our study can shed light on\rpathophysiological investigation of the relationship between COVID-19 disease causing a pandemic\rwith high mortality and virulence and blood types
