Significant regional differences in seroprevalence were not observed. All participants were PCR-negative during the study period. RESULTS: Seroprevalence (NT used as confirmation) in 2164 samples from 1184 players and staff was rather similar in May (23/1157, 1.99%) and June (21/1007, 2.09%). Participants were tested twice weekly using PCR from nasopharyngeal and/or oropharyngeal swabs. As screening assays, a commercial ELISA (Euroimmun) and a chemiluminescent immunoassay (CLIA) (Roche) were used, and an in-house neutralization assay (NT) was used as reference standard. METHODS: In this prospective cohort study seroprevalence was determined twice in May and June 2020 in players and staff from the German Bundesliga. ![]() B8.2 66123 Saarbrücken, Germany.ĪBSTRACT OBJECTIVES: Elite professional football players and staff are a unique group that might give insight into the epidemiology of severe acute respiratory syndrome coronavirus 2 ( SARS-CoV-2) infections in Germany and thus can serve as a model for geographical distribution and an estimation of undetected infections.
