In the second study, scientists examined 95 critically ill coronavirus patients in a hospital in Vancouver.

Between the blood types A, B and AB, no significant difference in rates of infection was found. The findings indicate why the coronavirus is lethal for some and not so for the others.

The research papers added evidence that there may be a connection between blood type and susceptibility to COVID-19 but the researchers stated that more studies need to be done to better understand why and what it means for patients. However, they remained in the intensive care unit (ICU) for longer on average.

Interestingly, blood groups, A and AB were also associated with complications post-hospitalization, such as myocarditis, lung injury and renal damage. Of the roughly 4,600 people who tested positive and reported their blood type, 38.4 percent had Type O blood.

That's lower than the prevalence of Type O in a population of 2.2 million Danish people, 41.7 percent, so the researchers determined that people with Type O blood had disproportionately avoided infection.

In general, your blood type depends on the presence or absence of proteins called A and B antigens on the surface of red blood cells - a genetic trait inherited from your parents.

The new studies about blood type and coronavirus risk align with prior research on the topic.

The data suggested that fewer people with blood type O were COVID-19 positive when compared with "A", "AB", and "B", suggesting that the latter groups are more vulnerable to be infected with the virus.

Types A and AB also needed a sort of dialysis that helps the kidneys filter blood without putting too much pressure on the heart more often than their counterparts. After controlling for certain factors, they found fewer patients with blood type O, compared with patients with blood types A, B, and AB.

Lead author of the study, Dr Mypinder Sekhon, of the University of British Columbia, said: "The unique part of our study is our focus on the severity effect of blood type on COVID-19".

Your blood type may predict how severely you'd be affected by Covid-19, should you catch infection.
