Abstract SARS-CoV-2, the coronavirus, spread across Germany within just a short period of time. Seroepidemiological studies are able to estimate proportion population with antibodies against SARS-CoV-2 infection (seroprevalence) as well level undetected infections, which not captured in official figures. In seroepidemiological study Corona Monitoring Nationwide (RKI-SOEP-2), biospecimens and in...
