What is special about those who have not contracted covid

The scientists explained that a person’s blood type also plays a role in who was destined to contract covid and who was not.

Since the early days of the Covid-19 pandemic, results published in the scientific journal Blood Advances have shown that people with blood type A were more vulnerable to contracting the new coronavirus. However, from the very first moment, scientists have been trying to find a logical explanation for what makes some people immune to covid.

At the first level, experts emphasize the possibility that many of our fellow citizens simply have not been diagnosed with coronavirus, but this does not mean that they have not been infected with it (have not been ill). In other words, they believe that there are many people who could have had the disease completely asymptomatic. In addition, the frequency of the covid test should be taken into account. To put it simply, “If you don’t take a test, you’ll never know, and it’s possible it was positive.” Added one more to the study. important element.

A person’s blood type also plays an important role in who gets infected and who doesn’t. In particular, people with blood type O are much less likely to get infected.

According to a new study published in the scientific journal Blood, people with blood type A are likely more vulnerable to COVID-19 infections. “The blood of people with different groups is not exactly the same molecular composition. In the first group, there are no antibodies to the A antigen, which bears little resemblance to the coronavirus antigen,” the experts explain.

A team of researchers led by Sean Stowell of Harvard University Medical School (USA) has proven that the SARS-CoV-2 virus that causes Covid-19 predominantly infects blood type A cells. Some studies show that among a group of several thousand people, the likelihood of infection after exposure to SARS-CoV-2, people with blood type A can be up to 20% higher than people with blood type O.
