Risk factors of SARS-CoV-2 seroprevalence among hospital employees in Italy: a single-centre study.

Background: The SARS-CoV-2 outbreak early in 2020 overwhelmed the Italian national health system, and hospitals were considered places at high risk of spreading the infection. We explored specific antibody seroprevalence of all employees at a single hospital in the epicentre of the outbreak, to identify areas of risk in nosocomial setting and to evaluate the usefulness of antibody testing.

Aims: Aim of this study was to explore SARS-CoV-2 seroprevalence in a single hospital workers cohort.
