The impact of <scp>ABO</scp> blood groups on clinical outcomes and susceptibility to <scp>COVID</scp>‐19: A retrospective study in an unselected population

Abstract

This study supports potential involvement of the ABO blood group system in predisposing to infection with SARS-CoV-2 in an unselected population. Examination of the mechanistic link between blood group and COVID-19 and its implications on controlling the current pandemic is warranted.
