Hospital-Wide SARS-CoV-2 Antibody Screening in 3056 Staff in a Tertiary Center in Belgium

Abstract

Belgium has a high burden of coronavirus disease 2019 (COVID-19), especially the region surrounding the Hospital East-Limburg, a tertiary care center.¹ Infection prevention measures were instituted in the hospital beginning March 4, 2020, including testing and contact tracing of all symptomatic patients and staff, changes in hospital operations, and provision of personal protective equipment (PPE). The first case was detected March 13 (Figure 1). We investigated the prevalence of antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) among hospital staff.
