“…At the onset of the COVID-19 pandemic, researchers and health professionals expressed concern about how the virus would affect people living in congregate settings, such as long-term care facilities ( Lai et al, 2020 ) and shelters ( Tsai and Wilson, 2020 ). Like these spaces, prisons were identified as high-risk sites for rapid contagion due to intersecting factors that included the health and social vulnerability of their residents, (over)crowded living arrangements that made physical distancing difficult or impossible, shared dining and sanitation spaces (e.g., bathrooms and showers), and the daily movement of large numbers of people (i.e., staff and visitors) into and out of prisons ( Barnert et al, 2020 ; Kinner et al, 2020 ; Ricciardelli et al, 2021 ; Yang and Thompson, 2020 ). In response to the challenges posed by COVID-19, prison systems internationally adopted various risk mitigation strategies, including mandating masks or personal protective equipment (PPE) for staff, regularly testing staff and prisoners, limiting prisoners’ time outside their cells, eliminating visits and programming, reducing staffing levels, and reducing the prisoner population ( Brennan, 2020 ; Lindström et al, 2020 ; Marcum, 2020 ; Ricciardelli et al, 2021 ).…”
