New Delhi, December 01, 2021 :
The research , conducted by Department of Research and Department of Blood Transfusion Medicine at Sir Ganga Ram Hospital has found that blood groups A, B and Rh+ are more susceptible to COVID-19 infection whereas O, AB and Rh- are at lower risk of Covid-19 infection. It also found that there is no association between blood groups and susceptibility to severity of disease as well as mortality.
This research has been published in November 21 edition of *“Frontiers in Cellular and Infection Microbiology”*.
According to Dr. Rashmi Rana, Consultant, Department of Research, Sir Ganga Ram Hospital, New Delhi, “Severe acute respiratory syndrome coronavirus 2 is a new virus, and it is unclear whether blood groups have any impact on Covid-19 risk or progression. Therefore, we investigated the association of ABO and Rh blood group with Covid-19 susceptibility, prognosis, recovery time, and mortality in this study.”
The study was conducted on total of 2,586 Covid-19 positive patients tested through real-time PCR who were admitted at SGRH from April 8, 2020 to October 4, 2020.
According to Dr. Vivek Ranjan, Co-author and Chairperson, Department of Blood Transfusion , 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 ≤ 60 years.”
Our study also found that Blood Group A and Rh + types are associated with a decrease in recovery period, whereas Blood Group O & Rh- are associated with increase in recovery period. However, the ABO and/or Rh blood groups may not be responsible for this association, as these may indicate an unexplored underlying factor like co-morbidity. Therefore, larger, multicenter, and prospective studies are needed to ascertain the relationship of between blood groups and SARS-CoV-2.
