According to a Ganga Ram Hospital study, blood classes A, B, and Rh+ are more susceptible to Covid-19

Meanwhile, the study claims that blood groups O, AB, and Rh- have a much decreased risk of infection.
According to a study conducted at Delhi’s Sir Ganga Ram Hospital, blood groups A, B, and Rh+ are more susceptible to Covid-19 infection, but blood groups O, AB, and Rh- are at a considerably reduced risk.

Between April 8 and October 4 2020, 2,586 Covid-19 positive participants were admitted to the hospital for the study. The findings were reported in Frontiers in Cellular and Infection Microbiology on November 21.

“Because the severe acute respiratory syndrome coronavirus 2 is a novel virus, it’s uncertain whether blood types influence Covid-19 risk or progression.”

As a result, in this study, we looked into the relationship between ABO and Rh blood groups and Covid-19 susceptibility, prognosis, recovery time, and mortality,” said Dr. Rashmi Rana, Consultant, Department of Research.

According to the study, the frequencies of the A, B, O, and AB blood types were 29.93 percent, 41.8 percent, 21.19 percent, and 7.89 percent, respectively, compared to 21.86 percent, 38.49 percent, 29.37 percent, and 10.28 percent in a control group of 79,325. 98.07 percent of the patients were Rh positive.

“We also discovered that male patients with blood group B are more susceptible to Covid-19 infection than female patients with the same blood group, and blood group AB was found to be more susceptible to infection in patients under the age of 60,” said Dr. Vivek Ranjan, co-author and chairperson of the Department of Blood Transfusion.

However, the researchers discovered no link between blood types and illness severity or mortality, according to the report. It was discovered that blood groups A and Rh+ are linked to a shorter recovery time, while blood groups O and Rh- are linked to a longer recovery time.

“…the ABO and/or Rh blood groups may not be responsible for this connection, as these may signal an undiscovered underlying component like comorbidity,” the study concluded. To determine the link between blood types and SARS-CoV-2, bigger, multicenter, and prospective studies are required.”
