blood group

The scientists are working around the clock to identify the Covid-19 risk factors. Over the course of the past ten months, scientists and the public realised that covid caused by the infectious SARS-COV-2 virus show different symptoms for everyone, ranging from mild, atypical, moderate and more terrible ones. The severity can also differ based on parameters like age, gender and co-morbidities.

Now two new studies that investigated the potential role of blood type in predicting the risk, revealed that people with blood group O are less vulnerable to the novel coronavirus infection than any other blood type.

The two studies published in Blood Advances show that people with blood group O are at lower risk of contracting the Covid-19 or SARS-CoV-2 infection.

The study also identifies ABO blood group as a risk factor for SARS CoV-2 infection but not hospitalisation or death from COVID-19.

This means that that person with blood types A, B, or AB may be at a higher risk of getting infected with Covid-19 than people with type O.

However, the researchers didn’t find any significant difference in the rate of infection between A, B, and AB types.
