With the results of new studies, people with blood type O do indeed appear to have a lower risk of contracting the coronavirus.
The results are becoming clearer. A recent study carried out by Spanish doctors on more than 6,000 patients shows that people in the O + group seem better protected from Covid-19. At the end of January, researchers from Inserm and the University of Nantes even wrote in the journal Virus “that a general consensus has emerged, according to which the O groups have a lower risk of the disease than the others. , between 10 and 33% less risk “.
“Researchers relate the proportion of blood groups in a population to the rhythm of the epidemic. O blood groups defend themselves better than others, because they have natural antibodies A and B. While the A n ‘have only B’s and vice versa, “according to a study reported by Franceinfo.
This blood group is not, however, a guarantee against the epidemic since an “O” can be infected by a host of the same group, carrying the virus.
Researchers will now go further to find, for example, better protection against the virus.
