People with blood type O have a lower chance of becoming infected with COVID-19 or developing serious diseases, says a study. Research published in the journal Annals of Internal Medicine looked at more than 225,000 people tested for COVID-19 between January 15 and June 30, 2020. Scientists have found that people with blood group O-negative have a 2.1% chance of testing positive for coronavirus – the lowest probability among all blood groups. The highest probability was 4.2% in the blood group B-positive. Read on – and to ensure your health and the health of others, do not miss this Sure Sign you already had.
The blood type led to a slightly lower risk of infection
The researchers found that people with blood group O had a lower chance of severe COVID disease or death compared to people with other blood groups.
In addition, people with Rh-negative blood were found to have a lower probability of both infections and severe COVID-19 diseases than people with Rh-positive blood.
“The O and Rh blood groups may be associated with a slightly lower risk of SARS-CoV-2 infection and severe COVID-19 disease, ‘the researchers concluded.

What does it 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 groups appear more protective against certain diseases than others. For example, people with type O blood are more likely to get cholera than people with other blood types.
This may be due to antigens, proteins that cover the surface of red blood cells and determine your blood type. When a virus or bacterium enters the body, those antigens cause the immune system to fight the invader. Some blood types seem more effective than others.
Specifically for COVID-19, people with type O blood have a lower tendency to form blood clots. One of the most serious – and poorly understood – complications of COVID-19 is that in some people the virus causes it to clot in the body. It can cause heart attacks, strokes and pulmonary embolisms, some of which can be fatal.
For now, these are theories that are being studied further. But at the moment, a few things are clear: people with type O blood are not immune to the coronavirus. No matter what your blood type, you should follow all public health recommendations to avoid contracting or spreading COVID-19.
