Seroprevalence of SARS-CoV-2 antibodies in healthcare workers at a London NHS Trust.

Healthcare workers (HCWs) have a theoretically increased risk of contracting SARS-CoV-2 given their occupational exposure. We tested 2167 HCWs in a London Acute Integrated Care Organisation for antibodies to SARS-CoV-2 in May and June 2020 to evaluate seroprevalence. We found a seropositivity rate of 31.6% among HCWs.
