The extensive spread of novel coronavirus19 (COVID19) had put a tremendous burden on health care facilities in investigation and prioritizing the treatment of COVID19 patients. Globally, as of 21 October 2020, there have been 40,455,651 confirmed cases of COVID-19, including 1,119,431 deaths, reported to WHO.Due to rapid increase in its alarmist state it is of prime importance to assess the factors influencing the COVID19 susceptibility. In our study we assessed one of the independent factors like blood group in COVID19 patients. We conducted a retrospective analysis to assess the prevalence and distribution of blood group among COVID19 patients in order to determine its susceptibility. In our study we assessed1000 COVID19 patients and their blood group was traced in order to find their distribution. In our study majority of COVID19 patients belong to A group and the least belongs to O and AB group. Although a detailed analysis is required for determining the association between blood group and COVID19 susceptibility, these data can throw light and form the basement for a future extensive study.
