Since the outbreak of the novel coronavirus, many factors including pre-existing medical conditions, obesity and old age have been linked to high risks of Covid infections. But as per a recent study, blood types can also determine Covid-19 contraction risks. That said, many scientists and medical professionals continue to study the link between SARs-COV-2 and the different blood groups and are in a bid to understand the same.

Possible association between blood type and Covid-19

A November 2020 study published in the medical journal Nature claimed that blood type can influence Covid risk. The study evaluated 14,000 individuals in the New York Presbyterian hospital system and found that people other than O-positive blood type were at a higher risk of contracting the virus.

In one of the earlier studies published in the journal, Blood Advances, which was conducted among 473,000 individuals who had tested positive for Covid-19 and a group of more than 2.2 million people, it was found that blood type O had a lower Covid contraction risk and organ complication.

Type A blood may increase risk of Covid, finds study

A recent Canadian study published in Blood Advances, evaluated a data that involved 95 patients with severe Covid-19 infection. Out of the 95 individuals, 84% had blood type A and required mechanical ventilation.

Comparatively, 61% of the group with blood type O and B needed similar treatment.

Researchers came to the conclusion that type A blood type has a higher risk of Covidcontractions than other blood types.

Which blood type has the lowest risk of infection?

As per the recent study and the researches conducted earlier, blood type O are at a lower risk of Covid-19 infections and are less vulnerable to the disease.

Experts suggest that different blood group types have a different impact on our circulatory system and changes the way blood is clotted in the body.

According to the research director at Inserm, a French medical research body, Jacques Le Pendu, individuals with blood type O are less at risk to develop clots, which tends to have a serious effect on the level of Covid severity and risks.        —Times of India
