Blood groups A, B, Rh+ more likely to catch Covid-19 infection, says study

An original research conducted by the Department of Research and Department of Blood Transfusion Medicine at a private hospital in Delhi has found that blood groups A, B, and Rh are more susceptible to Covid-19 infection.

On the other hand, O, AB, and Rh- are at lower risk of Covid-19 infection. It has also been found that there is no association between blood groups and susceptibility to the severity of disease as well as mortality. This research has been published in the November 21 edition of Frontiers in Cellular and Infection Microbiology".

"Therefore, we investigated the association of ABO and Rh blood group with Covid-19 susceptibility, prognosis, recovery time, and mortality in this study," he added. The study was conducted on a total of 2,586 Covid-19 positive patients tested through RT-PCR, who were admitted at SGRH from April 8, 2020, to October 4, 2020. According to Dr Vivek Ranjan, co-author and chairperson of the Department of Blood Transfusion at Sir Ganga Ram Hospital, New Delhi, "We also found that male patients of blood group B are more prone to Covid-19 than the female patients with blood group B and blood group AB was observed to be more susceptible to infection in patients with age group above 60 years."

Therefore, larger, multicentre, and prospective studies are needed to ascertain the relationship between blood groups and SARS-COV-2. -PTC News
