While vaccination in the world against the coronavirus advances and the hospitalization of people who make up risk groups decreases, scientists continue to investigate the particularities of SARS-CoV-2, the virus that killed more than 2.8 million people and forced all the cities of the world to carry out confinements.

A recent investigation, published in the journal Blood Advances, certifies that the virus has a preference for the antigen of blood group A that is found in the respiratory cells of people, as was already assumed several months ago.

To arrive at this determination, they evaluated a protein on the surface of the SARS-CoV-2 virus called the receptor-binding domain (RBD). This particle attaches itself to host cells, making it an important research goal to understand how infection occurs and how the virus behaves in each organism.

As detailed in the article, the team of experts said that "synthetic blood group antigens on red and respiratory cells found in individuals with blood groups A, B and O, and analyzed how SARS-CoV-2 RBD interacted with each type of single blood ". After these studies, they discovered that the virus has a marked preference for red blood cells of blood group A, which are found in respiratory cells. 

After these studies, they discovered that the virus has a marked preference for red blood cells of blood group A, which are found in respiratory cells. 

"It is interesting that viral RBD only prefers the type of blood group A antigens found on respiratory cells, which is presumably the way the virus enters most patients and infects them," said the author of the study, Sean R. Stowell, Brigham and Women's Hospital, in the United States.

Finally, they assured that type A blood implies a 50% greater risk of contracting the disease and going through it seriously. While group O conferred a "protective effect" on people: less risk of contagion and possibilities - in case of infection - of developing serious problems in the organs.
