Recent data suggests that people with blood type A have a significantly higher risk of acquiring COVID-19 than non-A blood types. Blood type O seems to have the lowest risk.
They pointed to the recent research that blood type plays a role in infection, noting the lower than expected prevalence of blood group O individuals among COVID-19 patients. Researchers also observed how blood groups are "increasingly recognized to influence susceptibility to certain viruses," among them SARS-CoV-1 and norovirus, adding that individuals with A, B, and AB blood types may be at "increased risk for thrombosis and cardiovascular diseases," which are important comorbidities among patients hospitalized with COVID-19.
Yes. The trouble is the AMA doing their thing and ripping out published studies.
