Blood group O is associated with a decreased risk for contracting SARS-CoV-2 infection, research published in Blood Advances showed. Identification of risk factors for contracting and developing serious illness following infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is of paramount interest. The study performed a retrospective cohort analysis of all Danish individuals tested for SARS-CoV-2 between 27 February 2020 and 30 July 2020, with a known ABO and RhD blood group, to determine the influence of common blood groups on virus susceptibility. Distribution of blood groups was compared with data from non-tested individuals. Participants (29% of whom were male) included 473654 individuals tested for SARS-CoV-2 using real-time polymerase chain reaction (7422 positive and 466232 negative) and 2204742 nontested individuals, accounting for 38% of the total Danish population.
