ABSTRACT
Background Implementing public health interventions can be challenging in carceral settings. Jails are institutions with the shortest lengths of stay, resulting in frequent turnover and constantly shifting populations. Jails had particularly acute challenges during the early stages of the COVID-19 pandemic, when incarcerated persons were highly susceptible to infection and severe disease. The purpose of this study was to identify barriers and facilitators to wastewater-based surveillance (WBS) and nasal self-testing (NST) as a combined strategy of COVID-19 surveillance in Fulton County Jail (FCJ), Atlanta, Georgia. Implications for efficient and effective infectious disease testing among this susceptible population are relevant for ongoing surveillance for current endemic pathogens and future epidemics.Methods We utilized a multilevel, theory-informed qualitative approach to conduct semi-structured one-on-one and small group interviews with nine distinct jail stakeholder groups: jail custody leadership, administrators, officers, maintenance workers, Georgia Department of Health’s COVID-19 testing contractor, jail health care leaders, nursing staff, laboratory leadership and staff. Interview guides and analyses were informed by the Consolidated Framework for Implementation Research (CFIR). We used directed content analysis to identify domains within CFIR reflecting barriers and facilitators to WBS combined with NST in large urban jail settings.Results Twelve interviews were conducted with administrative, healthcare, maintenance, custody, and laboratory personnel from July 2022 to November 2022. Seven CFIR constructs were identified as barriers, sixteen as facilitators, and one as a neutral factor for the implementation of WBS combined with NST. Jail stakeholders underscored the relative advantage for self-testing, highlighted limited resources, and expressed concerns for sustainability of WBS due to competing priorities. Many of the stakeholders within the jail setting that were interviewed had hierarchical organizational structures, which made decision-making processes regarding WBS and NST complex and challenging to implement.Conclusions Given the political, structural, and organizational factors in a jail setting, innovations such as NST and WBS require a rigorous implementation strategy supported by ongoing engagement and collaboration with a multitude of stakeholders.

BACKGROUND. In custodial settings such as jails and prisons, infectious disease transmission is heightened by factors such as overcrowding and limited healthcare access. Specific features of social contact networks within these settings have not been sufficiently characterized, especially in the context of a large-scale respiratory infectious disease outbreak. The study aims to quantify contact network dynamics within the Fulton County Jail in Atlanta, Georgia, to improve our understanding respiratory disease spread to informs public health interventions. METHODS. As part of the Surveillance by Wastewater and Nasal Self-collection of Specimens (SWANSS) study, jail roster data were utilized to construct social contact networks. Rosters included resident details, cell locations, and demographic information. This analysis involved 6,702 residents over 140,901 person days. Network statistics, including degree, mixing, and turnover rates, were assessed across age groups, race/ethnicities, and jail floors. We compared outcomes for two distinct periods (January 2022 and April 2022) to understand potential responses in network structures during and after the SARS-CoV-2 Omicron variant peak. RESULTS. We found high cross-sectional network degree at both cell and block levels, indicative of substantial daily contacts. While mean degree increased with age, older residents exhibited lower degree during the Omicron peak, suggesting potential quarantine measures. Block-level networks demonstrated higher mean degrees than cell-level networks. Cumulative degree distributions for both levels increased from January to April, indicating heightened contacts after the outbreak. Assortative age mixing was strong, especially for residents aged 20-29. Dynamic network statistics illustrated increased degrees over time, emphasizing the potential for disease spread, albeit with a lower growth rate during the Omicron peak. CONCLUSIONS. The contact networks within the Fulton County Jail presented ideal conditions for infectious disease transmission. Despite some reduction in network characteristics during the Omicron peak, the potential for disease spread remained high. Age-specific mixing patterns suggested unintentional age segregation, potentially limiting disease spread to older residents. The study underscores the need for ongoing monitoring of contact networks in carceral settings and provides valuable insights for epidemic modeling and intervention strategies, including quarantine, depopulation, and vaccination. This network analysis offers a foundation for understanding disease dynamics in carceral environments.

Background Wastewater-based surveillance (WBS) on an institutional level was implemented during the COVID-19 pandemic, including carceral facilities. In this study of a mega-jail, we examined the relationship between COVID-19 diagnostic test results from jail residents and the PCR signal for SARS-CoV-2 detection in weekly samples of jail wastewater over a 28-week period. Methods This study in a Georgia Jail (average population ~2,700) was conducted October 2021-May 2022. Weekly on-site wastewater samples were collected (Moore Swabs) and tested for SARS-CoV-2 RNA using RTqPCR. The source of wastewater was identified using a tracer dye. The jail offered residents rapid antigen testing at entry. We conducted periodic mass screenings via RT-PCR of nasal swabs. We aggregated individual test data, calculated the Spearman correlation coefficient, and performed logistic regression to examine the relationship between the strength of the SARS-CoV-2 PCR signal (Ct value) in wastewater and the proportion of the jail population that tested positive for COVID-19. Results Overall, 3770 individual nasal specimens were collected; 3.4% were COVID-positive. Weekly diagnostic test positivity ranged from 0%-29.5%. Dye tests demonstrated that a single wastewater collection point was sufficiently representative of the jails aggregate viral load. Twenty-five wastewater samples were collected. RT-qPCR Ct values for wastewater samples with SARS-CoV-2 RNA ranged from 28.1-39.9. A strong inverse correlation was observed between diagnostic test positivity and Ct value (r= -0.67, p < 0.01). Conclusion WBS was shown to be an effective strategy for surveilling COVID-19 in a large jail. Strong partnerships with the jail administration are essential to the success of WBS surveillance.

COVID-19ABSTRACT
In year one of the COVID-19 epidemic, the incidence of infection for US carceral populations was 5.5-fold higher than that in the community. Prior to the rapid roll out of a comprehensive jail surveillance program of Wastewater-Based Surveillance (WBS) and individual testing for SARS-CoV-2, we sought the perspectives of formerly incarcerated individuals regarding mitigation strategies against COVID-19 to inform acceptability of the new program. In focus groups, participants discussed barriers to their receiving COVID-19 testing and vaccination. We introduced WBS and individual nasal self-testing, then queried if wastewater testing to improve surveillance of emerging outbreaks before case numbers surged, and specimen self-collection, would be valued. The participants' input gives insight into ways to improve the delivery of COVID-19 interventions. Hearing the voices of those with lived experiences of incarceration is critical to understanding their views on infection control strategies and supports including justice-involved individuals in decision-making processes regarding jail-based interventions.
