Studies show Blood type may affect COVID-19 risk

Studies show Blood type may affect COVID-19 risk

New studies show people with Type A Blood have more chances of being infected by the coronavirus.

According to a study conducted on June 17 by the New England Journal of Medicine, a patient’s blood type may be linked to the risk of COVID-19 and respiratory failure. The study involved more than 2,000 patients with COVID-19 at seven different hospitals in Spain and Italy. People with blood type O are less at risk from the virus, the study shows.

“Our genetic data confirm that blood group O is associated with a risk of acquiring COVID-19 that was lower than that in non-O blood groups, whereas blood group A was associated with a higher risk than non-A blood groups.” Also Read– Hydroxychloroquine saved coronavirus patients

Blood type A not protected at all

Studies show Blood type may affect COVID-19 risk
According to a UK study, wearing a face mask in addition to lockdowns could lessen the spread of the infectious disease and in turn prevent a second wave of global pandemic.

An infectious disease physician at Stanford Health Care, Dean Winslow told reporters the study results are “very interesting” and added:  “I think the association they came up with is real. They found that patients with blood type O seem to be slightly protected from infections — period. And folks with blood type A were basically not protected from infection at all; they had a trend that was statistically significant of requiring oxygen supplementation or mechanical ventilation.” 

Another study conducted by Chinese researches earlier in March found that, “blood group A was associated with a higher risk for acquiring COVID-19 compared with non-A blood groups, whereas blood group O was associated with a lower risk for the infection compared with non-O blood groups,” according to the study’s authors.

Iahn Gonsenhauser, MD, patient safety and chief quality officer at State University Wexner Medical Center says that although study’s show these results, “it’s really important to understand that these are observational studies. They can show us a correlation, but they can’t show us a cause. They’re showing us there’s a pattern and they’ve identified a pattern and not whether they are [the cause] or are incidental.” Gonsenhauser further added that the studies are “reasonable observations.” and that “There are other related scientific findings and evidence that would suggest that this relationship may, in fact, be causal.”

Adds Gonsenhauser: “These findings should not change anybody’s behavior. We still need to be socially distancing and wearing masks. Those are our best tools.”
