All infections were confirmed by reverse transcriptase-polymerase chain reaction (RT-PCR) for SARS-CoV-2. After Institutional Review Board approval, we followed 201 patients requiring hospitalization due to COVID-19 infection during 7 consecutive months (March to October 2020) through a retrospective chart review. In the Washington, DC Veterans Affairs Medical Center, we are strategically situated to further investigate the outcomes of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in blacks since they represent approximately 60% of our patients. Of interest, Apea et al recently demonstrated higher mortality in patients from Asian and black backgrounds during COVID-19 infection after controlling for obvious confounders and frailty. Furthermore, a large study with more than 11,000 predominantly white race (83%) individuals concluded that ABO groups were not associated with disease susceptibility or severity and were unlikely to be useful predictors of COVID-19 severity in similar ancestries, raising the importance of extending these observations to more diverse populations. However, subsequent multivariate analysis found no association between blood type and risk of intubation or death after COVID-19 infection. ![]() Initial studies suggested that the lethality risk was increased or decreased with blood type A and O, respectively. During this global pandemic controversial data have been published on this topic. We were intrigued by the conclusion of Kumar et al that once patients are hospitalized with coronavirus disease 2019 (COVID-19) infection, blood type is not associated with severe disease or in-hospital mortality.
