Coronavirus: O Blood is Lucky for Coronavirus?

The results of two studies conducted in Canada and Denmark, published in the peer-reviewed online publication Blood Advances, sponsored by the American Society of Hematology recently, show that people with blood type O may have a lower risk of contracting COVID-19; People with blood type O are less likely to have serious consequences (including organ complications) if they are sick.

Researchers from the University of British Columbia in Canada found that among 95 severe COVID-19 patients, 84% of patients with blood types A and AB require mechanical ventilation. For patients with O or B blood, this proportion Is 61%. The median stay of the former in the intensive care unit was 13.5 days, while the median stay of the latter was 9 days. Researchers also found that more patients with type A and AB require dialysis to treat renal failure.

Dr. Mypinder Sekhon, the corresponding author of the study and the Intensive Care Unit of Vancouver General Hospital, said that when treating patients, blood type has always been “a lingering question in his mind”, but “needs to be repeated in many areas. Research and prove the existence of the same problem” can finally determine the answer. The reason behind this difference is still unclear; one explanation may be that people with type O blood are less prone to clotting, and clotting usually leads to more serious cases. But regardless of the patient’s blood type, Dr. Sekhon does not believe that the influence of blood type will replace other “severity risk factors” such as age or comorbidities.

The potential role of blood type in predicting the risk and complications of COVID-19 infection has become an important scientific issue. The results of these two new studies add to the evidence that there may be a link between blood type and susceptibility to COVID-19 infection; however, more research is needed to better understand the impact of blood type on COVID-19 patients.

Conclusion:

In a word, O blood people is much lucky when facing the infection of Coronavirus, but not free. Please note, luck is not free for infection. Therefore, just strictly abide by the isolation policies of the state and local governments and put yourself in a safe environment.
