Scientists talked about another factor of the disease COVID-19

In a material posted on the MedicalXpress portal, it is argued that in one study in Denmark, experts compared data from over 473,000 people who were tested for COVID-19.

So, among the patients there were fewer patients with the first blood group (AB0) and more with the second (A), third (B) and fourth (AB) groups.

Another study in Canada showed that among 95 critically ill patients who required intensive and mechanical ventilation of the lungs, the majority had blood types A and AB.

Earlier, the scientific director of the Mechnikov Research Institute of Vaccines and Serums, immunologist Vitaly Zverev, in an interview with URA.RU, noted that people with negative Rh factor "are more likely to get sick, including respiratory infections."
