Abstract
The aim of this study was to describe the rate of household, community, occupational, and travel-related COVID-19 infections among health care personnel (HCP). In a retrospective cohort study of 3694 HCP with COVID-19 infections from July 5 to December 19, 2020, we analyzed infection source data and rates, compared with local and state infection rates, and performed a correlation analysis. Household (27.1%) and community (15.6%) exposures were the most common sources of infection. Occupational exposures accounted for 3.55% of HCP infections. Unattributable infections (no known exposure source) accounted for 53.1% and correlated with community rather than occupational exposure ( R = 0.99 vs 0.78, P < 0.01). COVID-19 infections in this large HCP cohort correlated closely with infection rates in the community. The low incidence of occupational infections supports the effectiveness of institutional infection prevention and control measures.
