Abstract
Information on the impact of ABO blood group (BG) on SARS-CoV-2 infections is conflicting (1-4). To identify risk factors for severe COVID-19 courses we performed a cross-sectional study in volunteers between 18 and 61 years of age registered with DKMS for stem cell donation approved by the Institutional Review Board of the Technische Universität Dresden. All participants provided explicit consent that COVID-19 specific data were linked to genotype data in the donor registry file.
