Introduction Prior research has found coronavirus disease 2019 (COVID-19) cases to be disproportionately prevalent among U.S. prisoners. Like prisoners, prison staff experience ventilation and social distancing hazards and may have limited access to testing, paid sick leave, personal protective equipment, and other workplace protections. Yet, systematic case surveillance among prison staff remains unexplored. The objective of this study is to document trends in COVID-19 cases among U.S. correctional staff relative to prisoners and the U.S. population. Methods Reports of COVID-19 cases among prisoners and staff were collected from state Departments of Corrections and the federal Bureau of Prisons from March 31, 2020 to November 4, 2020. In November 2020, this series of aggregated case records was linked to population estimates to calculate COVID-19 period prevalence among prison staff and residents with comparison to U.S. population trends. Results Within the prison environment, COVID-19 case burden was initially higher among staff than prisoners in 89% of jurisdictions. Case prevalence escalated more quickly among prisoners but has remained persistently high among staff. By November 4, 2020, COVID-19 was 3.2 times more prevalent among prison staff than the U.S. population. Conclusions Prison staff experienced substantially higher COVID-19 case prevalence than the U.S. population overall. Across prison staff and resident populations, cases were rapidly rising in November 2020, indicating poor outbreak containment within the prison environment. An Emergency Temporary Standard, issued by federal and state Occupational Safety and Health Administrations, and priority vaccination are urgently needed to reduce COVID-19 occupational risk. Reduced occupational transmission of COVID-19 will benefit workers, incarcerated people, and community members alike.
