Show abstract
Seroprevalence studies can contribute to better assess the actual incidence of infection. Since long-term data for Germany are lacking, we determined seroprevalence of IgG-antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in 3,759 regular blood donors in three German federal states between July 2020 and June 2021. The IgG seroprevalence was 5.48% (95% confidence interval (CI): 4.77-6.25) overall, ranging from 5.15% (95% CI: 3.73-6.89) in Lower Saxony to 5.62% (95% CI: 4.57-6.84) in North Rhine Westphalia.
