Research Indicates Blood Type Could Influence COVID-19 Severity
A new research study published in The New England Journal of Medicine has found an intriguing pattern among those with severe cases of COVID-19.
The relatively limited study, in which approximately 2,000 European patients with severe cases of the disease were compared to people infected with the SARS-CoV-2 coronavirus who presented mild or no symptoms, appears to demonstrate that one's blood type can impact the way one experiences the disease.
Patients with type A blood were more prone to having severe COVID-19; those with type O were less so. Blood types are grouped according to the antigens on the surface of red blood cells; one hypothesis among researchers is that the proteins on type O blood are relatively more effective at "identifying" protein patterns on certain viruses.
