This blood type is more immune to Covid-19

A number of studies have shown that blood type can play a role in influencing the level of susceptibility to Covid-19 infection. However, it must be remembered that it does not mean that people with certain blood types can be more dangerous or vice versa.NBC wrote of two studies citing Blood Advances, a publication of the American Society of Hematology. The first study carried out by researchers in Denmark reviewed data on 473,654 people who were tested for Covid-19 from February to July. Most of the results were negative, with only 7,422 tests coming back positive.The researchers in the research found that blood type was a prominent differentiating factor between the two groups.

Blood type O was significantly associated with a decreased susceptibility to SARS-CoV-2 infection, "the study was quoted as saying, Friday (16/10/2020).As many as 38.4% of the total positive patients were people with blood type O. While 44.4% of positive patients were people with blood type A.This result means that people with blood type O are less likely to be infected with the corona virus that causes Covid-19. However, these findings are limited because of those tested, the availability of blood type information was only 62%.Therefore, it is also important to note that people with blood type O may also be infected.This study suggests, if you have type O, you have a slightly lower risk. But this reduction is small," said doctor Roy Silverstein, Chair of Medicine at the Medical College of Wisconsin.

Silverstein, who is also the former President of the American Society of Hematology, added that the reduction in vulnerability factors based on blood type is not the same as 0 percent risk. In addition, the findings of this new study will not change the way doctors treat Covid-19 patients.

"They will not differentiate the treatment between someone who comes to the hospital with blood type O, and patients whose blood type is type A. This difference is not too big," he continued.

However, the second study - on a smaller scale - seems to support the findings of the first study. In this study, experts from Canada analyzed data on 95 Covid-19 patients in Vancouver, between February and April. His condition was sick enough to be treated in an intensive care unit.
