The epidemic burden on prisons in Lombardy (Italy) during the first wave of the COVID-19 pandemic: the transmission and measures of prevention in detention facilities.

PURPOSE

Early on in the COVID-19 pandemic, the scientific community highlighted a potential risk of epidemics occurring inside prisons. Consequently, specific operational guidelines were promptly released, and containment measures were quickly implemented in prisons. This paper aims to describe the spread of COVID-19 in detention facilities within the Lombardy region of Italy during March to July 2020, and the impact of the prevention and control measures implemented.

DESIGN/METHODOLOGY/APPROACH: A descriptive retrospective analysis of case distribution was performed for all COVID-19 cases identified among people in detention (PiD) and prison officers (POs). A comparison of the epidemic burden affecting different populations and a correlation analysis between the number of cases that occurred and prevention measures implemented were also carried out.

FINDINGS

From this study, it emerged that POs were at a high risk of contracting COVID-19. This study observed a delay in the occurrence of cases among PiD and substantial heterogeneity in the size of outbreaks across different prisons. Correlation between reported cases among PiD and registered sick leave taken by POs suggested the latter contributed to introducing the infection into prison settings. Finally, number of cases among PiD inversely correlated with the capacity of each prison to identify and set up dedicated areas for medical isolation.

ORIGINALITY/VALUE: Prevention and control measures when adopted in a timely manner were effective in protecting PiD. According to the findings, POs are a population at high risk for acquiring and transmitting COVID-19 and should be prioritized for testing, active case finding and vaccination. This study highlights the critical importance of including prison settings within emergency preparedness plans.
