Persons with type A blood are more likely to get Covid-10--studies

You're More Likely to Have Severe Covid If You Have This Blood Type Studies suggest that certain blood types may leave you more at risk of COVID-19. See what the science says so far—and why people with Type O still need masks. Yahoo

Blood type doesn’t affect much in our daily lives. In fact, most people don’t even know whether they’re Type A, B, AB, or O. But the seemingly-banal detail might be a factor in who comes under the thumb of 2020’s world-wide tyrant—that is, coronavirus.

A new study in the journal PLOS Genetics revealed that people with Type A blood are more likely to have a severe case of Covid-19.

A previous study in the journal Blood Advances from 2020 also affirmed this research, adding that people with Type O blood seem to be more protected from Covid-19.

Researchers in China first shared this idea back in March 2020, and the findings were echoed by a paper out of Columbia University a month later. Even DNA testing company 23andMe tapped their customers and found that among 750,000 people (by far the biggest study population yet) who were diagnosed and hospitalized for COVID-19, those with type O were more protected.

Then, a study published in the New England Journal of Medicine confirmed the idea with a peer-reviewed study: Folks with Type A blood were 45 percent more likely to become infected with COVID-19 than those with other blood types, while those with Type O were 35 percent less likely. ...

So people with Type A may be more likely to catch the virus, but whether they also get it worse is still unclear: the NEJM study reports that people with Type A blood were also more likely to have respiratory failure.

However, the research out of Columbia University found there wasn’t really any difference among intubations or death and different blood types. And a 2020 study in the Annals of Hematology looked specifically at the link between blood types and the need for intubation or death in confirmed COVID-19 patients. They found no link between blood type and the severity of the illness. ...
