Correlation Between ABO Blood Group System And COVID-19 Severity In Erbil

Abstract

The incidence of SARS-CoV-2, or severe acute respiratory syndrome, can differ considerably, implying that personal characteristics affect how a disease grows. The aims to demonstrate a relationship between Kurdish patients' ABO blood groups and the severity of COVID-19. The study evaluated 300 COVID-19 patients who visited Rzgary Hospital and Zheen International Hospital in Erbil between April 2020 and December 2020, and collected data on age, gender, disease severity, and ABO blood groups. The chi-square statistic applied to examine the frequency and correlation of blood groups, and It was determined the odds ratios (ORs) and 95% confidence intervals (CIs). for severe and non-severe cases. The study included 186 males and 114 females aged 10 to 87 years old, and the blood groups frequencies A, O, B, and AB were 33.7%, 32.3%, 21.7%, and 12.3%, respectively. The study found no significant difference in COVID-19 severity for ABO blood groups A, O, B, and AB. Although there was a minor to moderate correlation between ABO blood group and COVID-19 severity, the chi-square analysis found that it was not statistically significant (p-value = 0.304). The odds ratios and 95% CIs for A, O, B, and AB blood types were 0.560 (0.256-1.224), 0.520 (0.236-1.114), 0.934 (0.436-2.00), and 0.768 (0.337-1.749), respectively.
