Since 11 March 2020, several papers reported the association between ABO blood groups and SARS-CoV-2/COVID-19. The authors compared ABO blood group distribution among 265 SARS-CoV-2-infected patients and 3,694 healthy controls. The SARS-CoV-2 viruses produced in individuals of groups A, B, AB and O express A, B, A and B antigens, and none, respectively. For example, SARS-CoV-2 viruses produced in group A individuals may express A antigens and infect group A or AB individuals without such antigen-antibody reactions.
