Recent studies reveal that people with blood group O have a lower risk from the coronavirus. The study suggests these people have a reduced likelihood of severe outcomes, including organ complications if they develop the disease.

Pandemic has shaken the whole world. So the global biomedical research community is working hard to make out coronavirus risk factors and potential therapeutic targets. Now researchers suggest a link between blood type and coronavirus risk. 

One of these studies discovered that COVID-19 patients with Type O or B blood spent lesser time in ICU(Intensive care unit) in comparison with Type A or AB. They were also found to be less likely to require ventilation and experience kidney failure.

Researchers studied 95 critically ill COVID-19 patients at hospitals in Vancouver, Canada, between February and April. They discovered Type O or B blood patients spent almost 4.5 lesser days in the ICU.

Blood type O may offer some protection against COVID-19 infection 

Another study revealed that Type O blood people may be at a lower risk of getting infected by this virus. In Netherlands, the team studied almost half a million people who were tested for COVID-19. The researchers found out that people with Type O blood had strangely avoided infection. 

Mypinder Sekhon, a co-author of the study, said, “I don’t think this supersedes other risk factors of severity like age and comorbidities and so forth,” 

“if one is blood group A, you don’t need to start panicking. And if you’re blood group O, you’re not free to go to the pubs and bars.”
