Abstract
Most cases of coronavirus disease 2019 are mild or asymptomatic. Therefore, many cases remain unrecorded. We determined seroprevalence of IgG antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in 3,186 regular blood donors in three German federal states between 9 March and 3 June 2020. The IgG seroprevalence was 0.91% (95% confidence interval (CI): 0.58-1.24) overall, ranging from 0.66% (95% CI: 0.13-1.19) in Hesse to 1.22% (95% CI: 0.33-2.10) in Lower-Saxony.
