The Relationship Between ABO and Rh Blood Groups and COVID19 Confirmed Patients, an Observational Study

Abstract

This is an observational study conducted on the patients admitted to Expo Field hospital Sharjah, United Arab Emirates (UAE) with the novel coronavirus disease-2019 (COVID-19) confirmed infection between March and May 2020. This disease caused by SRAS-CoV-2 virus discovered for the first time in Wuhan, China, in December 2019 and declared as a pandemic by World Health Organization (WHO) in 2020. We looked to the ABO and Rh blood groups distribution in 1014 COVID-19 confirmed patients. Our results showed that blood group O was the most common in these patients compared to the least common which is the ABO blood group. This is result goes with the findings of a few other studies that observed the association between the ABO blood type and COVID-19. However, this study has many limitations such as the non-availability of blood grouping in a considerable number of patients. In addition, there is no comparison with the data of normal blood group distribution of non-COVID-19 patients.
