People with O blood group are less likely to be infected by covid19
People with O blood groups are much less likely to get an infection of covid19. Australian researchers claim this is based on a database of DNA of over a million people. The research has been published in the New England Journal of Medicine.
Researchers also say that even if a person with O blood group gets infected with coronavirus, his or her condition is unlikely to be serious. James McFadden, the senior research fellow at the Baker Heart and Diabetes Institute of Australia, said that it is a very interesting revelation that the blood group has also been seen to have an impact on the likelihood of infection or reaching a serious level. A large-scale study of these preliminary findings can also help in finding a cure for corona.McFadden states that the coronavirus contains a spike protein, which grows rapidly with a cell that binds and infects it. Probably molecules from different blood groups react differently to this protein, which more or less increases the likelihood of infection. Assessment is also that the O blood group contains some natural antibodies, which reduces the risk of covid19.
O is the most common blood group. Around 48% of the population in the UK and Australia is blood group O. However, it is still unclear how these blood groups have different effects on different diseases. To hide this mystery, Australian institutions, through genetic testing company '23 And Me', prepared a DNA report by taking a sample of one million five thousand people by doing a genetic test.
Comparing these million people with their genome with information on whether or not they were infected with coronavirus, the result came out that people from the O blood group are less likely to be positive. The study was also uploaded to the research site MedRxive last week.
