ABSTRACT Introduction: The associations between ABO system of blood and COVID-19 infection in various studies provide reason to think true associations may be in reality between blood type and incidence of COVID-19 and death due to COVID-19. Objectives: To estimate frequency of COVID-19 illness in different ABO blood systems and also to find linkage between the ABO system of blood and degree of COVID-19 illness. Methods: A prospective cohort study was conducted on all COVID-19 patients (Patients were grouped A positive and A negative blood groups into 1 st group) admitted at Tertiary Care Hospital of Ahmedabad City, Gujarat, India during the four months of study duration. Results: COVID-19 infection was found in 380 (63.3%) male. Mean age was 56.46 ±15.35 years in which 26.8% patients were in age group of 60 to 70 years. Among total 600 patients, 35% of patients were having B positive type of blood followed by O positive type of blood (25%). There were 25% of patients having overall co-morbidity like diabetes. And 8% of B positive patient having co-morbidity and amongst the, 1.2% patients were admitted to Intensive Care Unit. Case fatality rate was 7.5%. Among B positive blood group patients, 37.8% deaths occurred. Conclusion: Patients having blood group O may have lower chances of ICU admission as compared to other blood groups.
