Response measures to COVID-19 in prisons and other detention centers.

PURPOSE: The purpose of this paper is to summarize activities being undertaken by the World Health Organization (WHO) Regional Office for Europe to prevent and control COVID-19 in and beyond prisons, activities specifically designed to increase information sharing and to support Member States, to comment on potential impacts of these initiatives at country-level responses and to underline the need for a rights-based approach to managing the pandemic, including the right to vaccination. DESIGN/METHODOLOGY/APPROACH: The Health in Prisons Programme (HIPP) of the WHO Regional Office for Europe worked with partner organizations to review regularly the evidence on best practices in prison health and use it to inform policy recommendations at the global level. HIPP issued overarching guidance and specific tools to support implementation of measures to prevent and control the spread of COVID-19 in prisons and other custodial settings. Moreover, to monitor the emergence of outbreaks, the HIPP developed a minimum data set for countries voluntarily to report COVID-19 cases and identify situations in need of direct support. FINDINGS: Since May 2020, the WHO has periodically received data from Member States, leading to the development of country-specific bulletins to support countries and, whenever appropriate, to organize virtual missions to further support ministries and public health bodies responsible for managing COVID-19 in prisons. ORIGINALITY/VALUE: The development of a specific set of indicators for prisons enables exploring data in a disaggregated manner. Monitoring response measures developed in prison enables judging their appropriateness to minimize the spread of SARS-CoV2 in prisons and alignment with guidance issued by the WHO.

Sustained cellular immune dysregulation in individuals recovering from SARS-CoV-2 infection.

SARS-CoV-2 causes a wide spectrum of clinical manifestations and significant mortality. Studies investigating underlying immune characteristics are needed to understand disease pathogenesis and inform vaccine design. In this study, we examined immune cell subsets in hospitalized and nonhospitalized individuals. In hospitalized patients, many adaptive and innate immune cells were decreased in frequency compared with those of healthy and convalescent individuals, with the exception of an increase in B lymphocytes. Our findings show increased frequencies of T cell activation markers (CD69, OX40, HLA-DR, and CD154) in hospitalized patients, with other T cell activation/exhaustion markers (PD-L1 and TIGIT) remaining elevated in hospitalized and nonhospitalized individuals. B cells had a similar pattern of activation/exhaustion, with increased frequency of CD69 and CD95 during hospitalization followed by an increase in PD1 frequencies in nonhospitalized individuals. Interestingly, many of these changes were found to increase over time in nonhospitalized longitudinal samples, suggesting a prolonged period of immune dysregulation after SARS-CoV-2 infection. Changes in T cell activation/exhaustion in nonhospitalized patients were found to positively correlate with age. Severely infected individuals had increased expression of activation and exhaustion markers. These data suggest a prolonged period of immune dysregulation after SARS-CoV-2 infection, highlighting the need for additional studies investigating immune dysregulation in convalescent individuals.
