Is the blood type linked to the risk of coronavirus infection?

A new preliminary study found correlations between the blood type and the likelihood of being hospitalized with COVID-19. According to the authors, people with type A blood may be more at risk than those with other blood groups.

A new preliminary study asks if the blood group could help predict the risk of COVID-19.

Researchers from the Southern University of Science and Technology in Shenzhen, China – in collaboration with colleagues from other Chinese institutions – recently conducted a study to evaluate the potential relationship between blood group and hospitalization due to SARS-CoV-2 infection. .

Their study is preliminary and has yet to be published in a peer-reviewed journal, which means that other experts have not yet had the opportunity to evaluate the methodology and results of the researchers.

However, they made their study document available online in pre-printed form.

The researchers looked at the distribution of blood groups among 2,173 people hospitalized with COVID-19, the disease caused by the new coronavirus. Each of them received assistance in one of the three hospitals in Wuhan, China or Shenzhen.

The team then compared the distribution of the patient’s blood groups with that of a representative group of the general population – a total of 3,694 people – in Wuhan.

The researchers found that the percentage of people with blood group A was significantly higher in the hospitalized group with COVID-19 than in the general population.

They also found that the percentage of people with blood type O was significantly lower in the COVID-19 group than in the general population.

Based on these findings, study co-author Jiao Zhao and colleagues report that “People with blood group A have a significantly higher risk for acquiring COVID-19 than non-A blood types, while the O blood group has a significantly lower risk for infection than non-O blood groups. “

Importantly, however, that researchers refer to the risk of hospitalization due to COVID-19, rather than the risk of contracting the virus that can lead to the disease.

This is because the team only looked at data from individuals whose symptoms were severe enough to require hospitalization, not those with mild symptoms that responded to home care.

But does this really mean that people with type A blood have added cause for concern, while those with type O can breathe out relieved?

Experts not involved in the research commented on the results, explaining that the study does not demonstrate a causal relationship between blood group and susceptibility to hospitalization with COVID-19.

Sakthi Vaiyapuri, Ph.D., associate professor of cardiovascular and poisonous pharmacology at the University of Reading in the United Kingdom, points out that people with type A blood shouldn’t worry about the results of this preliminary study.

“There is little evidence to support any claim [is] no more than a random correlation between the ABO blood group and COVID-19 susceptibility to contraction, “he says.

“There are too many parameters that question the credibility of [the researchers’] claims, which – even worse – are not mentioned in a pre-printed study with peer review, “warns Vaiyapuri.

“Without establishing causal links between [the coronavirus] and the antigens of the ABO blood group, it is difficult to understand this conclusion, which could be purely random. It is important to emphasize that people should not panic about these results, since, clearly, further scientific research is needed to substantiate these claims. “

Furthermore, the current study, which included data only from very specific populations in China, did not take into account some confusing factors, such as the distribution of blood groups varies from country to country.

However, if further research confirms the results of the study, they could help medical professionals identify those most at risk of applying for hospitalization due to infection with the new virus.
