Blood group O was associated with a lower risk of COVID-19 than blood groups A, B, and AB.

Jul 18, 2021 · The authors found that individuals with type O blood were less likely to contract SARS-CoV-2 compared with non–type O blood groups (ARR = 0.88; 95% confidence interval [CI], 0.84–0.92). Rhesus (Rh)-negative individuals were also less likely to be diagnosed with SARS-CoV-2 (ARR = 0.79; 95% CI, 0.73–0.85).
