Your blood type may determine whether you get COVID-19.

Recent research by a genetic testing firm in California reveals that people with Type O blood are not only 14% less likely to get COVID-19 than other blood types, they are also 19% less likely to require hospitalization. By contrast, people with blood Type AB were the most susceptible to getting the disease.

According to the International Business Times, the potentially groundbreaking study was conducted by 23andMe, a direct-to-consumer genetic testing group that worked with 750,000 volunteers to uncover the genetic traits that may influence this highly contagious disease.

The Economic Times reports that scientists who compared the genes of thousands of patients in Europe found that those who had Type A blood were more likely to have severe disease, while those with Type O were less likely. These reports confirm a previous Chinese study of such links between COVID-19 and blood type.

Dr. Eric Topol, head of the Scripps Research Translational Institute in San Diego, said that the evidence of the role blood type places in the infection rates and complications of the virus is "tentative, it isn't enough of a signal to be sure."
