Does your blood group make you more susceptible to the emerging coronavirus?

Dubai, United Arab Emirates (CNN) – Typically, the difference in your blood type causes a very slight difference in your daily life, unless you need to have a blood transfusion, however, some studies have made people question whether the blood type affects the risk of injury One has the new Corona virus.

A study published this week addresses some of those early results.

Researchers from the Massachusetts Hospital and the Beth Israel Dikons Hospital published a study on Thursday that did not find any evidence that the blood group affected whether a person would have severe symptoms when developing Covid-19.

A puzzle in evolution

They are not the only humans to have blood types, as at least 17 different species of primates also have it, including chimpanzees and gorillas, and blood types go back 20 million years.

The fact that blood groups continue for a long time by chance is not expected, according to evolutionary and human geneticist and researcher at the National Museum of Natural History in France, Laur Sigurel, and it is likely that they give us a kind of evolutionary advantage.

“The evolutionary interest in maintaining these species may not be related to their function in the blood, but it is likely that they are the result of their function in the respiratory and digestive tissues,” which are the most places exposed to viruses and bacteria, she said.

While we do not know exactly how, Sigorel said that the variation in the blood type gene affects our susceptibility to various diseases.

We know that some blood types are more likely to develop certain diseases.

For example, the “B” blood group is associated with a lower risk of cancer, while the “O” blood group has been linked to a lower risk of death from acute malaria, however, it is more likely to have a “norovirus” that causes vomiting and diarrhea.

What about the new corona virus?

The study, published Thursday, may address some research that claims the blood group’s impact on a person’s infection with the “Covid-19” virus. A doctor from Mass General Hospital, Anahita Dua, who led the study team, said: “We showed during a multi-institutional study that no Reason to believe that being a member of a particular ABO blood group increases the severity of the disease, which we have identified requires intubation, or death. ”

There are two hypotheses about the relationship between blood groups and “Covid-19”, according to the director of research at the French Organization for Medical Research “Inserm”, Jacques-le-Pindo.

One of them states that people with the “O” family are less likely to have thrombolytic problems, which is the main driver of the severity of “Covid-19” disease.

Le Pindo said that it can also be explained by the possibility that the virus will carry the antigen of the infected blood group.

As such, the antibody produced by an individual with a blood type “O” may equal the virus when a person with a blood group “A” is exposed to it, similar to the rules for blood transfusion.

However, Lou Pindo said: “This protection mechanism will not work in all situations. A person belonging to the O blood group can infect another person who belongs to the O blood group, for example.”

Luo Pindo also explained that it was not likely to have any significant protective effect, and that the amounts of antibodies varied greatly from person to person.

People with “A” blood group should not be anxious, and people with “O” blood group should not relax, according to Assistant Professor of Cardiovascular Pathology and Toxicology at Reading University in the UK, Sakatville. Vyaburi.

Fayaburi confirmed that there are many underlying factors. He said: “We think this is a respiratory virus, but it is really a whole bunch of things that happen, which we don’t yet understand.”
