Blood-borne and sexually transmitted infections: a cross-sectional study in a Swiss prison.

ABSTRACT: BACKGROUND:Incarcerated people carry a high burden of infection, including blood-borne diseases (BBDs). It is also known that one million people contract a sexually transmitted infection (STI) every day worldwide, which represents a global public health challenge. However, data regarding the prevalence of STIs and the risk factors among incarcerated populations are lacking. The objective of this study was to determine the prevalence and associated factors of BBDs and STIs among detainees in the largest pre-trial prison in Switzerland. METHODS:In a cross-sectional study conducted at the Champ-Dollon pre-trial prison, 273 male detainees answered a standardized questionnaire and were screened for syphilis, herpes simplex virus 2 (HSV-2), HIV, and hepatitis C (HCV). Prevalence rates and associations of BBDs and STIs with risk factors were computed. RESULTS:Most participants (90.9%) were migrants from outside Western Europe, and 5.9% were injecting drug users. HCV was diagnosed among 6.2% of participants (antibody prevalence). The prevalence of HCV was higher among injecting drug users (81.2%) than non-injectors (1.6%). The prevalence of HIV, syphilis, and HSV-2 was 0.4%, 1.1%, and 22.4%, respectively. HCV was associated with a history of injecting drug use and HSV-2 with a lower education level and being older than 26 years. CONCLUSIONS:This study showed the infection prevalence of 2-9 times higher among detainees than in the Swiss community. It also illustrated that these infections are associated with sociodemographic and risk factors. Therefore, the prison environment offers an opportunity to strengthen infectious disease control programs targeting specific subgroups of at-risk people. Such programs would benefit both the prison population and broader society.

Project description:Sexually transmitted and blood-borne infections (STBBI)-which include HIV, hepatitis B and C, chlamydia, gonorrhea, syphilis and human papillomavirus-remain significant public health issues both nationally and globally. In 2018, a Pan-Canadian STBBI Framework for Action (the Framework) was released by federal, provincial and territorial governments to provide an overarching and comprehensive approach to addressing STBBI for all those involved. This includes all levels of government, First Nations, Inuit and Métis communities and leadership, frontline service providers, clinicians, public health practitioners, non-governmental organizations and researchers. The Framework includes strategic goals, guiding principles and pillars for action to address STBBI in Canada. In response, the Government of Canada released its own action plan in July 2019: Accelerating Our Response - Government of Canada Five-Year Action Plan on Sexually Transmitted and Blood-Borne Infections (the Action Plan). This document identifies seven priority areas for federal action on STBBI over the next five years: 1) moving toward truth and reconciliation with First Nations, Inuit and Métis Peoples; 2) stigma and discrimination; 3) community innovation-putting a priority on prevention; 4) reaching the undiagnosed-increasing access to STBBI testing; 5) providing prevention, treatment and care to populations that receive health services or coverage of health care benefits from the federal government; 6) leveraging existing knowledge and targeting future research; and 7) measuring impact-monitoring and reporting on trends and results. The Government of Canada is currently working with provincial and territorial governments, First Nations, Inuit and Métis partners, and other stakeholders to develop STBBI indicators and targets for the Canadian context that are appropriate, feasible and measurable against the shared strategic goals of the Framework and the Action Plan. In addition, the Government of Canada has also committed to reporting annually on its progress in implementing the priority areas laid out in the Action Plan.

Project description:BackgroundThis study estimated the prevalence of curable sexually transmitted and reproductive tract infections (STIs/RTIs) among pregnant women attending antenatal care (ANC) in rural Zambia, evaluated the effectiveness of syndromic management of STIs/RTIs versus reference-standard laboratory diagnoses, and identified determinants of curable STIs/RTIs during pregnancy.MethodsA total of 1086 pregnant women were enrolled at ANC booking, socio-demographic information and biological samples were collected, and the provision of syndromic management based care was documented. The Piot-Fransen model was used to evaluate the effectiveness of syndromic management versus etiological testing, and univariate and multivariate logistic regression analyses were used to identify determinants of STIs/RTIs.ResultsParticipants had a mean age of 25.6?years and a mean gestational age of 22.0?weeks. Of 1084 women, 700 had at least one STI/RTI (64.6%; 95% confidence interval [CI], 61.7, 67.4). Only 10.2% of infected women received any treatment for a curable STI/RTI (excluding syphilis). Treatment was given to 0 of 56 women with chlamydia (prevalence 5.2%; 95% CI, 4.0, 6.6), 14.7% of participants with gonorrhoea (prevalence 3.1%; 95% CI, 2.2, 4.4), 7.8% of trichomoniasis positives (prevalence 24.8%; 95% CI, 22.3, 27.5) and 7.5% of women with bacterial vaginosis (prevalence 48.7%; 95% CI, 45.2, 51.2). An estimated 7.1% (95% CI, 5.6, 8.7) of participants had syphilis and received treatment. Women <?20?years old were more likely (adjusted odds ratio [aOR]?=?5.01; 95% CI: 1.23, 19.44) to have gonorrhoea compared to women ?30. The odds of trichomoniasis infection were highest among primigravidae (aOR?=?2.40; 95% CI: 1.69, 3.40), decreasing with each subsequent pregnancy. Women 20 to 29?years old were more likely to be diagnosed with bacterial vaginosis compared to women ?30 (aOR?=?1.58; 95% CI: 1.19, 2.10). Women aged 20 to 29 and???30?years had higher odds of infection with syphilis, aOR?=?3.96; 95% CI: 1.40, 11.20 and aOR?=?3.29; 95% CI: 1.11, 9.74 respectively, compared to women under 20.ConclusionsCurable STIs/RTIs were common and the majority of cases were undetected and untreated. Alternative approaches are urgently needed in the ANC setting in rural Zambia.

Project description:BackgroundStudies have demonstrated the significance of commercial sex work in the ongoing transmission of HIV and other sexually transmitted infections (STIs) in India. Clients of female sex workers (FSWs) are thought to be an important bridging population for HIV/STIs. However, there is a lack of information on basic characteristics of sex work clients. This study sought to describe the prevalence of HIV and other STIs, as well as examine the determinants of these pathogens among a sample of clients in south India.MethodsData were from a cross-sectional biological and behavioural survey of FSW clients from six districts in Karnataka State, India. The prevalence of HIV, syphilis, herpes simplex virus type 2 (HSV-2), chlamydia (CT) and gonorrhoea (NG) among clients was examined. Multivariable logistic regression models were used to analyse the socio-demographic, sexual behaviour and sex-work related characteristics related to the prevalence of each pathogen. Sampling weights and appropriate survey methods were utilized in regression models to account for complex sampling design.ResultsThe total sample size was 2,745. The average age of clients was 30.4 (SE:0.3). Across the total sample, the prevalence of HIV, HSV-2, syphilis and CT/NG was 5.6%, 28.4%, 3.6% and 2.2%, respectively. The prevalence of HIV/STIs varied substantially across districts, reaching statistical significance for HIV (p<.0001) and CT/NG (p=.005). In multivariable models, duration of paying for commercial sex was associated with increased risk for HIV and HSV-2 (AOR: 1.1; 95%CI: 1.0-1.1, p<.0001). Clients with brothels as a main FSW solicitation site were associated with increased risk of HIV (AOR: 2.4; 95%CI: 1.2-4.7, p=.001), while those frequenting lodges were at increased risk for CT/NG (AOR: 6.3; 95%CI: 1.9-20.6, p=.03). Examining co-infections, clients with HSV-2 infections were at substantially higher risk of being HIV-positive (AOR: 10.4; 95%CI: 6.1-17.7, p<.0001).ConclusionsThis study fills in important gaps in knowledge regarding clients in southern India. The strong association between HIV and HSV-2 infections highlights the complications in designing effective prevention, intervention and management programs of this well-hidden population.
