Coronavirus disease 2019 (COVID-19) symptoms, patient contacts, polymerase chain reaction (PCR) positivity and seropositivity among healthcare personnel in a Maryland healthcare system

In a large, system-wide, healthcare personnel (HCP) testing experience using severe acute respiratory coronavirus virus 2 (SARS-CoV-2) polymerase chain reaction (PCR) and serologic testing early in the coronavirus disease 2019 (COVID-19) pandemic, we did not find increased infection risk related to COVID-19 patient contact. Our findings support workplace policies for HCP protection and underscore the role of community exposure and asymptomatic infection.
