Study: Does Blood Type Impact Risk Of COVID-19

There are many factors that may increase or decrease the risk of coronavirus like underlying health conditions, age and gender. Blood type is also a factor to increase or decrease the risk for coronavirus. Experts say that your blood type can increase or decrease the risk for novel coronavirus.


In Wuhan, to check whether blood type impacts COVID-19 contraction, scientists noted the blood types of 2,173 COVID-19 positive people. They then compared blood types of general population in that area.

They found that in general population, blood type A was 31%; type B was 24%, type AB was 9% and type O was 34%.

In the people affected by Covid-19, they found that blood type A was 38%; type B was 26%, type AB was 10% and type O was 25%.

Chinese study concluded that people with blood group O are more secure from coronavirus than people with blood group A. Experts worried that people with blood group A might panic or worry and people with blood group O might become careless about coronavirus.

The difference between the risk for coronavirus to people with different blood type is certain antibodies in the blood.

Researchers researched on just about 2,000 people. They should test it on a large number of people to check its validity.

Patricia Foster, PhD, a microbiologist and professor emerita of biology at Indiana University, told “This is an interesting study but it needs verification. If they can come up with more solid numbers and bigger studies, it’s something to look out for.”

Dr. Mary Cushman, MSc, professor at the Larner College of Medicine at the University of Vermont wondered if the type O people in families should be the ones sent out for shopping, for instance. However, she added that O blood grouped people should not neglect safety precautions.

US experts also researched on the relationship between coronavirus and blood type. They analyzed the results of 1,559 individuals who were tested for novel coronavirus and whose blood type was known. Nicholas Tantonetti, PhD, associate professor of biomedical informatics, systems biology, and medicine at Columbia University in New York City explained that because of small size of the research, not enough individuals with blood type B were there to draw any conclusions on blood type B for coronavirus risk.


Cushman said, “These results aren’t useful to lessen the serious precautions that everyone needs to take, regardless of their blood type.”

Researchers believed that one should follow the precautions for coronavirus even though the researches showed that COVID-19 may not affect people of particular blood type. It is because there is a lot about coronavirus that is unknown.

Cushman emphasized that everyone needs to continue washing their hands; keep a physical distance from others, and follow all the things public health experts are recommending.

She also said that it’s very compelling and the results are not entirely surprising since they know blood group is important in other settings and viruses.
