Severe Acute Respiratory Syndrome Coronavirus 2 Seropositivity among Healthcare Personnel in Hospitals and Nursing Homes, Rhode Island, USA, July–August 2020

H ealthcare personnel face higher risk of infec- tion during the coronavirus disease (COVID-19) pandemic because of their essential role in identifying and treating persons affected (1,2).Although essential workers in many occupations have higher risk of infection because of face-to-face interaction with the public, personnel in hospitals and nursing homes have more frequent and prolonged contact with persons known to be infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).Hospitals and nursing homes are potential hotspots of infection transmission.Hospital personnel conduct activities ranging from infection screening to administering advanced life support measures and may be exposed to patients with high viral loads (3).Infection risk can be exacerbated by shortages in personal protective equipment (PPE) and other resources, including staff (4,5).Nursing homes have been referred to as "ground zero" (6) of the pandemic because resident deaths have contributed disproportionately to overall COVID-19 mortality (2,7).Several factors may increase intrafacility transmission, including residents with risk factors for severe COVID-19 disease and prolonged viral shedding (e.g., advanced age, underlying conditions), a large proportion of asymptomatic infections, and new resource constraints alongside long-standing challenges (8-11).Assessing SARS-CoV-2 seropositivity among hospital and nursing home personnel may reveal risk factors that can be addressed through additional interventions.Community transmission has been identified as a primary determinant of transmission in both nursing homes and hospitals ( 12,13), Severe Acute Respiratory Syndrome Coronavirus 2 Seropositivity among Healthcare Personnel in Hospitals and Nursing Homes, Rhode Island, USA,
