A study at Delhi’s Sir Ganga Ram Hospital has found that blood groups A, B and Rh+ are at a higher risk of contracting Covid-19 infection, The Indian Express has reported. The same study has shown that blood groups O, AB and and Rh- are at a significantly lower risk of the infection.
The study was conducted in 2,586 Covid-19 positive patients who were admitted to the hospital from April 8 2020 to October 4 2020.
The researchers have also found that male patients with blood group B are more prone to Covid-19 than female patients with the same blood group, the report said.
However, the study says that they found no association between blood groups and susceptibility to severity of disease and mortality. It did find that blood groups A and Rh+ types are associated with a decrease in recovery period while blood groups O and Rh- are associated with increase in recovery.
