Seroprevalence and associated factors of HIV and Hepatitis C in Brazilian high-security prisons: A state-wide epidemiological study.

ABSTRACT: The prevalence of hepatitis C virus (HCV) and the acquired immunodeficiency virus (HIV) is much higher in prisons than in community settings. Some explanatory factors for this burden include putative aspects of the prison environment, such as unprotected sexual relations and sexual violence, use of injectable drugs and syringe sharing. Nonetheless, efforts in better understanding the dynamics of both HCV and HIV are scarce in developing countries such as Brazil, which poses a risk not only to the inmates but to the community as well. In this investigation, we sought to determine the seroprevalence and sociodemographic and behavioral risk factors associated with HIV and anti-HCV antibodies among men detained at high-security institutions. This is an epidemiological, proportionally stratified observational study including 1,132 inmates aged 18 to 79 years-old (Mage = 32.58±10.18) from eleven high-security prisons located in the State of Paraná, Brazil. We found that HIV and anti-HCV prevalence were 1.6% (95% CI: 1.0-2.5) and 2.7% (95% CI: 1.0-2.5), respectively. Risk factors associated with HIV included not receiving intimate visits (OR = 8.80, 95% CI: 1.15-66.88), already having another sexually transmitted infection (OR = 3.89, 95% CI: 1.47-10.29), and reporting attendance in HIV preventive campaigns (OR = 4.24, 95% CI: 1.58-11.36). Moreover, anti-HCV seroprevalence was associated with higher age (OR = 4.03, 95% CI: 1.61-10.07), criminal recidivism (OR = 2.58, 95% CI 1.02-6.52), and the use of injectable drugs (OR = 7.32, 95% CI 3.36-15.92). Although prisons might increase the risk for acquiring and transmitting HIV and HCV, the adoption of permanent epidemiological surveillance programs could help reducing the circulation of viruses, involving strategies focusing on screening, treating, and preventing infections to assure proper prisoner health. Moreover, these policies need to take place inside and outside the prison environment to offer continued assistance to former prisoners once they leave the institution.

Project description:BackgroundToxocariasis is a worldwide helminthic zoonosis caused by infection with the larvae of the ascarid worms that comprise the Toxocara spp. Children are particularly prone to infection because they are exposed to the eggs in sandboxes and playgrounds contaminated with dog and cat feces. Certain behaviors, such as a geophagy habit, poor personal hygiene, a lack of parental supervision, close contact with young dogs, and ingestion of raw meat, as well as gender, age, and socioeconomic status, affect the prevalence of the disease. However, previous studies of the risk factors for toxocariasis have generally produced inconsistent results. An epidemiological cross-sectional study was conducted to evaluate the seroprevalence of IgG anti-Toxocara spp. antibodies and associated factors in schoolchildren from a region in the southeast of Brazil.Methodology/principal findingsA total of 252 schoolchildren aged 1 to 12 years (120 males and 132 females) were assessed. An enzyme-linked immunosorbent assay based on Toxocara canis larval excretory-secretory antigens was used to determine outcomes. A questionnaire was used to collect information on children, family, and home characteristics. Clinical and laboratory data completed the dataset investigated in this study. Seroprevalence was 15.5% (95%CI 11.5-19.8). Geophagy (aPR 2.38 [95%CI 1.36-4.18], p-value 0.029) and the habit of hand washing before meals (aPR 0.04 [95%CI 0.01-0.11], p-value ≤ 0.001) were factors associated with increased and decreased seroprevalence, respectively. The income factor and its related variables lost statistical significance after adjustment with a multiple Poisson regression model.Conclusions/significanceThe current study confirms that toxocariasis is a public health problem in the evaluated area; modifiable factors such as soil contact and personal hygiene appear to have a greater influence on the acquisition of infection than sociodemographic attributes, thus representing direct targets for disease prevention and control.

Project description:BackgroundCarceral settings are a key focus of the 2030 WHO global hepatitis C virus (HCV) elimination goals. Despite this, access to HCV testing and treatment services in prisons remains low globally, limiting opportunities to achieve these goals. Advocacy efforts are needed to address service inequities and mobilise support for enhanced HCV programs in prisons globally. INHSU Prisons, a special interest group of the International Network on Health and Hepatitis in Substance Users (INHSU) is developing a Prisons HCV Advocacy Toolkit to address this need. Here we present findings of a mixed study to inform the development of the Toolkit.MethodsThe aim of this study was to inform the development of the Toolkit, including understanding barriers for scaling up prison-based HCV services globally and advocacy needs to address these. An online survey (n = 181) and in-depth interviews (n = 25) were conducted with key stakeholders from countries of different economic status globally. Quantitative data were statistically analysed using R Studio and qualitative data were analysed thematically. The data sets were merged using a convergent design.ResultsKey barriers for enhanced prison-based HCV services included lack of political will and action, lack of prison-based healthcare resources, and poor awareness about HCV and the importance of prison-based HCV services. These findings underscore how advocacy efforts are needed to motivate policymakers to prioritise HCV healthcare in prisons and ensure funds are available for services (including diagnostic tools and treatment, healthcare teams to implement services, and systems to measure their success). Advocacy resources to raise the awareness of policy makers, people working in the prison sector, and incarcerated populations were also identified as key to increasing HCV service uptake.ConclusionThe Toolkit has the potential to support advocacy efforts for reaching HCV elimination targets. By understanding the advocacy needs of potential Toolkit end-users, the findings can inform its development and increase its accessibility, acceptability, and uptake for a globally diverse audience.
