Coronavirus: People in this blood group have a lower risk of infection

Hamm – a lot about it Coronavirus the researchers still puzzled. The course of the disease seems unpredictable. Some people have no symptoms, others get seriously ill, and many don’t even get infected. Risk factors such as Alter is Pre-existing disease are now known. Now the search suggests that the blood group plays a not insignificant role.

Anyone who has ever been to the blood donation knows which one blood group he or she belongs. The surface structure of red Blood cells determines if the person must Group 0, A, B or AB heard. Doctors speak of the second most common in Germany Blood group 0 (41%) therefore settle for red Blood cells it does not find proteins – also called antigens.

Coronavirus: People in this blood group have a lower risk of infection

People with the extension Blood group A however, around 43% of the German population carries certain carbohydrates on the surface of the Erythrocytes. People with the extension Blood group B however, others, people with the extension Blood group AB they have both groups of carbohydrates. But what does this have to do with it Coronavirus do?

A study from Graz, Austria, has now confirmed the hypothesis made by some Chinese researchers. People with the extension Blood group 0 they are less likely to deal with Coronavirus SARS-CoV-2 infect. This was the result of a large-scale study by Eva Maria Matzhold and Thomas Wagner of the University Clinic for Serology and Blood Group Transfusion Medicine of the Medical University of Graz.

Coronavirus: People in this blood group have a lower risk of infection

For the study, the scientists obtained data from 399 Covid patients valued. All were hospitalized due to the course of the disease. “The results of our study show that people with Blood group 0 are statistically significantly less likely to be involved COVID-19 get sick like people with the Blood group A, B or AB“, Thomas Wagner is quoted in a press release.

however, the blood group does not affect the severity of the course of the disease. A Chinese study had previously found that an above-average number of patients with Coronavirus the Blood group A had. A European study estimates the probability of one infection with the Coronavirus with the Blood group A to 50 percent.

This blood group is better protected from coronary infection

People with the extension Blood group 0 they are, however, 50% better than before Coronavirus protected. Fr.de * also talks about it. However, this does not mean the whole clear, like a death in Hamm after a wedding. Will the next bloc follow in NRW and Germany? “People with Blood group zero they still have to protect themselves immediately, “says transfusion specialist Thomas Wagner orf.at quoted.

Experts from the University of California, Riverside and the University of Southern California are currently researching at the molecular level why symptoms occur COVID-19 they are so different. Six genes have been found so far with SARS-CoV-2 to interact. The new findings are intended to help develop new therapeutic approaches. *fr.de is part of the Ippen-Digital network.
