Early Research from 23andMe Strengthens Link Between Blood Types and Covid-19

September 14, 2020

(STAT News) – A forthcoming study from genetic testing giant 23andMe shows that a person’s genetic code could be connected to how likely they are to catch Covid-19 — and how severely they could experience the disease if they catch it. It’s an important confirmation of earlier work on the subject. People whose blood group is O seemed to test positive for Covid-19 less often than expected when compared to people with any other blood group, according to 23andMe’s data; people who tested positive and had a specific variant of another gene also seemed to be more likely to have serious respiratory symptoms.
