People with the second blood type most often die from complications caused by a coronavirus, believe Iranian scientists. The preprint of their research was published on the MedRxiv portal. Earlier the Chinese and American specialists came to the same conclusion.
As a result, the authors of all three works noted that the worst infection is carried by people with the second blood type. Slightly less often died patients with the third and fourth groups, and the least vulnerable to COVID-19 scientists called people with the first blood type.
The publication specifies that the impact of blood group on the severity of the disease is not associated with any complications or risk factors that were infected.
Head of the Federal Medical and Biological Agency Veronika Skvortsova earlier also said that coronavirus most often infected people with the second blood type. However, she admitted that this may be due to the fact that this group is the most common.
According to the World Health Organization, more than 8.7 million people in the world were infected with Coronavirus, and more than 461 thousand died. In Russia have revealed 585 thousand cases of COVID-19, about eight thousand people have died, more than 339 thousand have recovered.
