This blood type protects against COVID, according to a study


People with blood group O are less likely to become infected with COVID-19 or to develop a serious illness, according to a study. Research published in the journal Annals of Internal Medicine observed more than 225,000 people who had been tested for COVID-19 between January 15 and June 30, 2020. Scientists found that people with blood type O negative had a 2.1% chance of test positive for coronavirus, the lowest probability of all blood groups. The highest probability was in blood group B positive, with 4.2%. Read on, and to ensure your health and the health of others, don’t miss out on these sure signs that you’ve already had coronavirus.

Blood type resulted in “slightly lower risk” of infection

The researchers found that people with blood type O were less likely to suffer severe COVID illness or death compared to people with other blood types.

Additionally, people with Rh negative blood were found to have a lower chance of COVID-19 infection and serious illness than people with Rh positive blood.

Blood types O and Rh− may be associated with a slightly lower risk of SARS-CoV-2 infection and severe COVID-19 disease, “the researchers concluded.

What does this mean?

The results are not entirely surprising. Other peer-reviewed studies have reached the same conclusion about COVID.

And scientists have previously found that certain blood types appear to be more protective against certain diseases than others. For example, people with type O blood tend to get more ill from cholera than people with other blood types.

It can be due to antigens, proteins that coat the surface of red blood cells and determine your blood type. When a virus or bacteria enter the body, those antigens activate the immune system to fight the invader. Some blood types appear to be more effective sentinels than others.

Specifically for COVID-19, people with type O blood are less likely to form clots overall. One of the most serious (and poorly understood) complications of COVID-19 is that in some people, the virus causes blood clots to form throughout the body, which can lead to heart attacks, strokes, and pulmonary embolisms, some of the which can be fatal.

For now, these are theories that are under study. But at this point, some things are clear: People with type O blood are not immune to the coronavirus. No matter what your blood type is, you must follow all public health recommendations to avoid contracting or spreading COVID-19.
