Coronavirus: People with this blood group least vulnerable to COVID-19

There again, it was observed that of all blood group types, blood type O (positive or negative) was the most "protected" ones of all.

While a pair of new studies, published Wednesday in health journal Blood Advances, suggests blood type can be tied to COVID-19, experts said the way patients are being treated will not yet change. "We have the advantage of a strong control group - Denmark is a small, ethnically homogenous country with a public health system and a central registry for lab data - so our control is population-based, giving our findings a strong foundation".

People with blood type O may have a lower risk of infection from the SARS-CoV-2 virus, that causes COVID-19, and reduced likelihood of severe outcomes, including organ complications, if they develop the disease, two new studies suggest, the studies suggested.

A retrospective study of individuals tested for coronavirus showed that blood type O "may offer some protection against COVID-19 infection".

Previous studies have indicated similar results in patients with blood type O.

In the first study, scientists in Denmark analyzed data from 473,654 people tested for the virus between February and July, CNN reported.

The study suggests that people with blood types A, B, or AB may be more likely to be infected with COVID-19 than people with type O.

A total of 38 patients had blood types A or AB, and 57 had blood types O or B.

The second study examined data from 95 critically ill people who were hospitalized with Covid-19 in Vancouver, Canada. After controlling for certain factors, they found fewer patients with blood type O, compared with patients with blood types A, B, and AB. For example, people with type A blood produce different antibodies to people with blood type O. It's still not known, however, whether this has any significant effect on a person's ability to battle Covid-19. They found the portion of patients who needed mechanical ventilation was higher in those with blood type A or AB when compared with a group of patients with blood type O or B.

More than this, the research team also found that more of these patients required dialysis for kidney failure.

The second research is based on almost 95 people from Vancouver, Canada who had tested positive for the virus.

Also this summer, the genealogy website 23andMe.com released data they collected from 750,000 participants who identified they have tested positive for COVID-19.
