No link between blood types and risk of serious illness or death from Covid-19


Blood type is a trait determined by a person’s DNA and linked to genes inherited from their parents. These genes determine the presence of antigens on the surface of red blood cells. Antigens are available in two versions, A and B, also known as erythrocytes, which are found on the surface of red blood cells.

People’s blood type is determined according to the presence of these antigens, AB who has both groups, and those who do not have any of them have O blood groups. Another antigen in cells called Rhesus is stated that the blood type is positive or negative.

Dr Jeffrey Anderson and his team of the Intermountain Medical Center Heart Institute in Salt Lake City have refuted studies done in China, Europe, Boston, New York and elsewhere.

Within the scope of the research published in the JAMA Network Open, the health records of more than 100 thousand people who had Covid-19 tests in Utah, Idaho and Nevada between March and November 2020 were analyzed and no relationship was found between blood type and disease.

NO BLOOD GROUP AMONG PROVEN FACTORS INCREASING THE RISK

The authors of the study used the expressions, “Given the large and forward-looking nature of our study, it is unlikely that Covid-19 is associated with blood groups.”

Scientists, on the other hand, cannot explain why previous studies yielded different conclusions, but cited various factors that may have led to previous results. They said that unclassified statistical data and genetic differences may have led to skewed results indicating that certain blood groups are at greater risk.

However, the study found that while not blood type, other factors actually increase the risk of Covid-19. These included being men, older as well as people of non-white ethnicity.

“We found that among individuals with Covid-19, the rate of hospitalization was related to their gender, ethnicity, and age,” the researchers said.
