Right from the beginning, COVID-19 struck unevenly across population, and scientists have been trying to understand the reasons. Why are some individuals more vulnerable than others and why are some relatively protected?
New research suggests that blood types could play a rather significant role in the spread and progression of COVID-19.
A recent study published in the New England Journal of Medicine focused on the relevance of blood types in terms of susceptibility to infection. Researchers analyzed the different blood types with regards to COVID-19 and discovered that people with blood type O are less likely to become infected with the Coronavirus. However, they are not completely resistant against an infection with the virus but the study shows they have the lowest risk of having a severe case of the disease.
According to the same study, people with blood type A seem to be rather more vulnerable to the infection and at a particularly high risk of a severe course of COVID-19 after having contracted the disease.
“When [people with blood type A] were infected, it appeared they had a slightly elevated risk of requiring oxygen administration or going to the intensive care unit,” said Dr. Dean Winslow, an infectious disease specialist at Stanford Health Care.
After a rigorous analysis of the study, Dr. Winslow agrees that there seems to be a correlation between blood type and infection. Still, statistics show that people with type O were only 35 percent less likely to become infected with COVID-19 so they definitely can’t rest assured. Therefore, as the risk is still significant, he advises people to continue to practice social distancing and other protective measures.
“You just have to look at that as potentially one of the factors,” he said. “Certainly I would recommend that people of any blood type practice social distancing and wear a face covering.”
Respecting the protective measures and keeping the immune system strong by exercising both the body and the mind should be enough to keep us healthy.
“I certainly encourage people to stay active and really take care of themselves physically,” Winslow said. ” Eat a good diet and exercise, and remember that human beings, we’re physical beings and we have emotional needs. So I encourage people to try as best as they can to try to maintain that balance in their lives.”
