Investigation and response to an outbreak of Neisseria meningitidis serogroup Y ST-1466 urogenital infections, Australia.

Abstract: In 2023, an increased number of urogenital and anorectal infections with Neisseria meningitis serogroup Y (MenY) were reported in New South Wales (NSW). Whole genome sequencing (WGS) found a common sequence type (ST-1466), with limited sequence diversity. Confirmed outbreak cases were NSW residents with a N. meningitidis isolate matching the cluster sequence type; probable cases were NSW residents with MenY isolated from a urogenital or anorectal site from 1 July 2023 without WGS testing. Of the 41 cases, most were men (n = 27), of whom six reported recent contact with a female sex worker. Five cases were men who have sex with men and two were female sex workers. Laboratory alerts regarding the outbreak were sent to all Australian jurisdictions through the laboratories in the National Neisseria Network. Two additional states identified urogenital MenY ST-1466 infections detected in late 2023. Genomic analysis showed all MenY ST-1466 sequences were interspersed, suggestive of an Australia-wide outbreak. The incidence of these infections remains unknown, due to varied testing and reporting practices both within and across jurisdictions. Isolates causing invasive meningococcal disease (IMD) in Australia are typed, and there has been no MenY ST-1466 IMD recorded in Australia to end of March 2024. Concerns remain regarding the risk of IMD, given the similarity of these sequences with a MenY ST-1466 IMD strain causing a concurrent outbreak in the United States of America.

The impact of policing and homelessness on violence experienced by women who sell sex in London: a modelling study.

Street-based sex workers experience considerable homelessness, drug use and police enforcement, making them vulnerable to violence from clients and other perpetrators. We used a deterministic compartmental model of street-based sex workers in London to estimate whether displacement by police and unstable housing/homelessness increases client violence. The model was parameterized and calibrated using data from a cohort study of sex workers, to the baseline percentage homeless (64%), experiencing recent client violence (72%), or recent displacement (78%), and the odds ratios of experiencing violence if homeless (1.97, 95% confidence interval 0.88-4.43) or displaced (4.79, 1.99-12.11), or of experiencing displacement if homeless (3.60, 1.59-8.17). Ending homelessness and police displacement reduces violence by 67% (95% credible interval 53-81%). The effects are non-linear; halving the rate of policing or becoming homeless reduces violence by 5.7% (3.5-10.3%) or 6.7% (3.7-10.2%), respectively. Modelled interventions have small impact with violence reducing by: 5.1% (2.1-11.4%) if the rate of becoming housed increases from 1.4 to 3.2 per person-year (Housing First initiative); 3.9% (2.4-6.9%) if the rate of policing reduces by 39% (level if recent increases had not occurred); and 10.2% (5.9-19.6%) in combination. Violence reduces by 26.5% (22.6-28.2%) if half of housed sex workers transition to indoor sex work. If homelessness decreased and policing increased as occurred during the COVID-19 pandemic in 2020, the impact on violence is negligible, decreasing by 0.7% (8.7% decrease-4.1% increase). Increasing housing and reducing policing among street-based sex workers could substantially reduce violence, but large changes are needed.

What may encourage or deter health services utilization by people living with or at the risk of HIV/AIDS in special health centers? Qualitative evidence from a stigmatized community.

BACKGROUND: Behavioral Diseases Counseling Centers (BDCCs) and Vulnerable Women's Counseling Centers (VWCCs) in Iran are the main peripheral centers that offer educational, counseling, diagnostic, preventive, curative and protective services to individuals living with or at high risk of contracting HIV/AIDS and female sex workers respectively. Due to the social stigma surrounding HIV in Iran, this study aims to identify the factors that may hinder or encourage HIV/AIDS patients and women with risky sexual behaviors from visiting these centers. METHODS: Conducted in 2023, this qualitative study involved individuals visiting BDCCs and VWCCs in two western provinces of Iran, Ilam and Kermanshah. The study participants included 21 health staff members working in BDCCs and VWCCs and 20 HIV/AIDS patients and vulnerable women with unsafe sexual behaviors referring to these centers. Purposive, snowball and maximum variation sampling techniques were applied to interview the participants. Interviews were conducted between January 5th and May 21st, 2023, using a semi-structure guideline. Interviews were transcribed and content analysis approach was applied to analyze data using MAXQDA20 software. RESULTS: According to the findings, the barriers and facilitators of visiting specialized centers for HIV/AIDS patients and vulnerable women were categorized into three main categories, 10 subcategories and 35 sub-subcategories including: Medical and operational processes (4 subcategories and 12 sub-subcategories), mutual interactions between the personnel and visitors (people living with and at the risk of getting HIV/AIDS) (3 subcategory and 13 sub-subcategories), and physical characteristics of the centers (3 subcategories and 10 sub-subcategories). CONCLUSIONS: To improve the performance of BDCCs and VWCCs and encourage people living with and at the risk of contracting HIV/AIDS to visit these centers regularly, health policy makers should consider modifying clinical processes, physical features, personnel behaviors and visitors' concerns raised by the interviewees and the issues identified in this study.

Size estimation of key populations and 'bridge populations' based on the network scale-up method in Ukraine.

INTRODUCTION: Correct estimation of the size of key and bridge populations is crucial for an efficient HIV/AIDS response in resource-limited settings, enabling efficient program planning and resource allocation. The hidden nature of these groups poses challenges to traditional methods, leading to the adoption of innovative approaches like the network scale-up method (NSUM). In this article we present the results of a NSUM study conducted in 2020 in Ukraine, focusing on four key populations and three bridge populations, highlighting challenges and contributions to development of the method. METHODS: From July to September 2020, we conducted a nationally representative survey in Ukraine via computer-assisted telephone interviews, and applied the known population method and summation method to estimate social networks sizes. Results were weighted based on individual sampling probability and adjusted for social respect and visibility factors to address potential limitations. RESULTS: Our study achieved a 20% response rate with 10,000 completed interviews. The social network size, using the known population method, was 213 people, and 125 using the summation method. Adjusting for the social respect and visibility, estimated key populations sizes were 295,857 [248,714-343,001] people who inject drugs, 152,267 [109,960-194,573] men who have sex with men, 78,385 [57,146-99,619] sex workers, and 9,963 [7,352-12,571] transgender people, detailed by age and gender. Bridge populations were estimated at 62,162 [50,445-73,879] sexual partners of people who inject drugs, 284,348 [233,113-335,583] clients of sex workers, and 13,697 [7,370-20,026] female partners of men who have sex with men. CONCLUSIONS: NSUM proves reliable for estimating key populations size with appropriate corrections. It shows promise for further use in Ukraine, considering limited geographic coverage of the integrated bio-behavioral studies to use multiplier-based methods. However, the validity concerns persist for estimating bridge populations size, emphasizing the need for further method refinement and addressing implementation issues, particularly those related to data collection.

Expanding access to healthcare for people who use drugs and sex workers: hepatitis C elimination implications from a qualitative study of healthcare experiences in British Columbia, Canada.

BACKGROUND: Hepatitis C virus (HCV) is a major health threat in Canada. In British Columbia (BC) province, 1.6% of the population had been exposed to HCV by 2012. Prevalence and incidence of HCV are very high in populations of people who use drugs (PWUD) and sex workers (SW), who may experience unique barriers to healthcare. Consequently, they are less likely to be treated for HCV. Overcoming these barriers is critical for HCV elimination. This research sought to explore the healthcare experiences of PWUD and SW and how these experiences impact their willingness to engage in healthcare in the future, including HCV care. METHODS: Interpretive Description guided this qualitative study of healthcare experiences in BC, underpinned by the Health Stigma and Discrimination framework. The study team included people with living/lived experience of drug use, sex work, and HCV. Twenty-five participants completed in-depth semi-structured interviews on their previous healthcare and HCV-related experiences. Thematic analysis was used to identify common themes. RESULTS: Three major themes were identified in our analysis. First, participants reported common experiences of delay and refusal of care by healthcare providers, with many negative healthcare encounters perceived as rooted in institutional culture reflecting societal stigma. Second, participants discussed their choice to engage in or avoid healthcare. Many avoided all but emergency care following negative experiences in any kind of healthcare. Third, participants described the roles of respect, stigma, dignity, fear, and trust in communication in healthcare relationships. CONCLUSIONS: Healthcare experiences shared by participants pointed to ways that better understanding and communication by healthcare providers could support positive change in healthcare encounters of PWUD and SW, who are at high risk of HCV infection. More positive healthcare encounters could lead to increased healthcare engagement which is essential for HCV elimination.

Enhancing sexual health and empowerment among migrant women sex workers: a community health worker-led intervention in Marseille, France.

Introduction: Given the high infection rate of sexually transmitted infections (STI) among migrant women sex workers (WSWs), it is necessary to understand how to improve prevention, information and care for this vulnerable population. Community health workers (CHWs), by linking community to health services, are positioned to improve health outcomes in migrant communities. This article aims to describe a pilot innovative intervention performed by CHWs to improve sexual health in migrant WSWs. Methods: This one-year intervention study used a respondent-driven sampling (RDS) to recruit a representative cohort of migrant WSWs in Marseille, France. Four CHWs were recruited from different communities and participated in all stages of the research. They performed individual and group interventions of prevention, support in care and empowerment. Data on participant characteristics, type of intervention and adherence to the intervention were reported via questionnaires given to participants. Simultaneously, semi-structured interviews and informal interviews of migrant WSW, CHWs and care providers were carried out. Results: A total of 132 migrant WSWs were included in the cohort. Very few of them knew about PrEP (12%) or already used HIV post-exposure treatment (9%). Migrant WSWs were often victims of rape or racism, 15 and 21%, respectively. In two-thirds of cases the level of health literacy was low. Participants suffered from a combination of vulnerability factors: difficulties with access to social rights, food or housing. Only 13% reported having benefited from medical follow-up or assistance by an NGO in the 3 months prior to the program. By 3 months, more than one third of the participants had been tested for HIV (35%) and 63% knew about PrEP. A total retention rate of 70% was reported in the cohort after 6 months. Conclusion: CHWs enabled to improve care access for migrant WSWs by improving the collaboration between care and social actors at a local level. Through these "bring-back-to" interventions for this hard-to-reach population, CHWs enabled an optimization of the care pathway. Our results also highlight the importance of a population-based approach for individual and group support of empowerment interventions in order to strengthen their capacity for action.

Prevalence and factors associated with psychological distress among key populations in Nigeria.

BACKGROUND: Stigmatization and discrimination within healthcare settings deter key populations (KPs) from seeking mental health and psychosocial support (MHPS). Consequently, understanding the prevalence, associated factors, and impact of the MHPSS intervention on psychological distress among Nigeria's KPs is crucial. METHOD: This is a cross-sectional study focused on KPs, including Female Sex Workers (FSW), Men who have Sex with Men (MSM), and People Who Inject Drugs (PWID) enrolled in Heartland Alliance LTD/GTE across 17 One-Stop Shops (OSS) in six states of Nigeria. Data were extracted from the databases of the OSS. PD was assessed using the Mental Health Screening Form III (MHSF-III). Descriptive statistics and univariable and multivariable binary logistic regression models were done using IBM-SPSS version 28. RESULTS: The prevalence of PD among the KPs was 9.7%. Higher rates were observed among FSWs (12.0%). Of the 22310 KPs, the prevalence of PD was 9.7%. The major dependants of PD include being a PWID with PD prevalence of 8.5% and AOR of 1.95 (95% CI: 0.60-0.98, p = 0.015), alcohol intake with PD prevalence of 97.7% and AOR of 21.83 (95% CI: 15.13-56.83, p<0.001), and having experienced gender-based violence with PD prevalence of 99.0% and AOR of 25.70(95% CI: 17.10-38.73, p<0.001). All Participants (100%) were given brief intervention, and 1595 of 2159 (73.8%) were referred for further psychological intervention. The services with the highest proportion were psychoeducation (21.20%), followed by coping skills training (17.70%) and motivational enhancement (12.90%). CONCLUSION: The study highlights the critical need for targeted mental health interventions among KPs in Nigeria, primarily focusing on those with a history of substance abuse and gender-based violence. Despite universal brief interventions, the proportion enrolled in further Psychosocial support indicates a need to improve mental health service utilization among the KPs in Nigeria.

Leveraging Routinely Collected Program Data to Inform Extrapolated Size Estimates for Key Populations in Namibia: Small Area Estimation Study.

BACKGROUND: Estimating the size of key populations, including female sex workers (FSW) and men who have sex with men (MSM), can inform planning and resource allocation for HIV programs at local and national levels. In geographic areas where direct population size estimates (PSEs) for key populations have not been collected, small area estimation (SAE) can help fill in gaps using supplemental data sources known as auxiliary data. However, routinely collected program data have not historically been used as auxiliary data to generate subnational estimates for key populations, including in Namibia. OBJECTIVE: To systematically generate regional size estimates for FSW and MSM in Namibia, we used a consensus-informed estimation approach with local stakeholders that included the integration of routinely collected HIV program data provided by key populations' HIV service providers. METHODS: We used quarterly program data reported by key population implementing partners, including counts of the number of individuals accessing HIV services over time, to weight existing PSEs collected through bio-behavioral surveys using a Bayesian triangulation approach. SAEs were generated through simple imputation, stratified imputation, and multivariable Poisson regression models. We selected final estimates using an iterative qualitative ranking process with local key population implementing partners. RESULTS: Extrapolated national estimates for FSW ranged from 4777 to 13,148 across Namibia, comprising 1.5% to 3.6% of female individuals aged between 15 and 49 years. For MSM, estimates ranged from 4611 to 10,171, comprising 0.7% to 1.5% of male individuals aged between 15 and 49 years. After the inclusion of program data as priors, the estimated proportion of FSW derived from simple imputation increased from 1.9% to 2.8%, and the proportion of MSM decreased from 1.5% to 0.75%. When stratified imputation was implemented using HIV prevalence to inform strata, the inclusion of program data increased the proportion of FSW from 2.6% to 4.0% in regions with high prevalence and decreased the proportion from 1.4% to 1.2% in regions with low prevalence. When population density was used to inform strata, the inclusion of program data also increased the proportion of FSW in high-density regions (from 1.1% to 3.4%) and decreased the proportion of MSM in all regions. CONCLUSIONS: Using SAE approaches, we combined epidemiologic and program data to generate subnational size estimates for key populations in Namibia. Overall, estimates were highly sensitive to the inclusion of program data. Program data represent a supplemental source of information that can be used to align PSEs with real-world HIV programs, particularly in regions where population-based data collection methods are challenging to implement. Future work is needed to determine how best to include and validate program data in target settings and in key population size estimation studies, ultimately bridging research with practice to support a more comprehensive HIV response.

Syphilis seroprevalence and associated factors: A cross-sectional study in formal female sex workers in a province of Peru.

Syphilis is a sexually transmitted infection (STI) considered a public health problem that affects vulnerable and at-risk populations, such as sex workers. We designed a retrospective cross-sectional study based on the review of health evaluation records of sex workers who attended consultations to obtain comprehensive health cards at a Health Center in the Province of San Vicente de Cañete in Peru during the year 2020. We obtained sociodemographic and employment information and the RPR (rapid plasma reagin) test results to diagnose syphilis. We evaluated 220 records of sex workers with a mean age of 27.9 ±â€…6.9 years and the initiation of sexual relations of 16.0 ±â€…1.6 years, while the accumulated time they had as sex workers was 2.9 ±â€…2.4 years. 85.9% of those evaluated reported being heterosexual. The prevalence of syphilis was 7.3% (CI95: 4.2%-11.5%). Being a homosexual sex worker was significantly associated with syphilis (OR: 19.6; 95% CI: 4.8-80.0) compared to heterosexuals. The prevalence of syphilis presented a value similar to that reported in other Latin American and national studies, and it is evident that it is a health problem among sex workers.

Application of the UNAIDS Incidence Patterns Model to Determine the Distribution of New HIV Infection in Lagos State, Nigeria.

BACKGROUND: Identifying patterns in the distribution of new HIV infections in the population is critical for HIV programmatic interventions. This study aimed to determine the distribution of New HIV infection by applying the incidence patterns mathematical model to data from Lagos state. METHODS: The incidence patterns model (IPM) software is a mathematical model developed by UNAIDS to estimate the demographic and epidemic patterns of HIV infections. This model was adapted in Lagos state to predict the distribution of new HIV infections among specified risk groups in the next 12 months. RESULTS: The IPM predicted a total HIV incidence of 37 cases per 100 000 individuals (3979 new infections) will occur among the 15 to 49 subpopulations. The results also showed that sero-concordant HIV-negative couples with external partners (29%), female sex workers (26%), men-having-sex-with-men (18%), and previously married females (6%) accounted for the majority of the estimated new HIV infections. Overall, key populations constitute almost half (48%) of the estimated number of new HIV infections. CONCLUSION: The study helped to identify the population groups contributing significantly to new HIV infections. Therefore, priority interventions should be focused on these groups.

Estimating turnover and industry longevity of Canadian sex workers.

How long indoor sex workers stay employed in collectives is a poorly understood aspect of sex worker agency in industrialized democracies. This study provides estimates of turnover, the rate at which workers leave employment, using a subsample of 76 collectives representing 3545 workers over a one-year period. All the collectives provided data on individual workers via external websites. The collectives were identified in a larger random sample of 783 advertisers from a popular Canadian classifieds site used by sex workers, all of whom provided URLs as part of their ad contact information. Monthly between October 2022 and October 2023, individual workers associated with the subsample of advertisers were identified from web pages maintained by these advertisers and scheduling data was collected where available. Worker turnover was estimated based on whether workers were visible one month to the next. Over the year, estimated turnover ranged from 12.0% to 16.0% (mean 14.2% SD 1.1%). Turnover was not affected by month or number of workers in the collectives. Mean 41.1% workers (SD 23.5%, N = 51 advertisers) were scheduled on any given day. Workers were visible for a mean 5.5 months (SD 4.5) with those visible for one month being the largest single group. Most sex workers in collectives are likely not permanent full time employees, and the extremely brief work histories of many suggest that failure in the industry may be common for this subpopulation.

Epidemiology of gonorrhoea: systematic review, meta-analyses, and meta-regressions, World Health Organization European Region, 1949 to 2021.

BackgroundEpidemiology of Neisseria gonorrhoeae (NG) infection remains inadequately understood.AimWe aimed to characterise NG epidemiology in Europe.MethodsWe used Cochrane and PRISMA guidelines to systematically review, report, synthesise and analyse NG prevalence data from 1949 to 30 September 2021. Random-effects meta-analyses estimated pooled prevalence. Meta-regression analyses investigated associations and sources of heterogeneity.ResultsThe 844 included publications yielded 1,573 prevalence measures. Pooled prevalence of current urogenital infection was 1.0% (95% CI: 0.7-1.2%) among general populations, 3.2% (95% CI: 1.8-4.8%) among female sex workers, 4.9% (95% CI: 4.2-5.6%) among sexually transmitted infection clinic attendees and 12.1% (95% CI: 8.8-15.8%) among symptomatic men. Among men who have sex with men, pooled prevalence was 0.9% (95% CI: 0.5-1.4%), 5.6% (95% CI: 3.6-8.1%), and 3.8% (95% CI: 2.5-5.4%), respectively, for current urogenital, anorectal or oropharyngeal infection. Current urogenital, anorectal or oropharyngeal infection was 1.45-fold (95% CI: 1.19-1.77%), 2.75-fold (95% CI: 1.89-4.02%) and 2.64-fold (95% CI: 1.77-3.93%) higher among men than women. Current urogenital infection declined 0.97-fold (95% CI: 0.96-0.98%) yearly, but anorectal and oropharyngeal infection increased (1.02-fold; 95% CI: 1.01-1.04% and 1.02-fold; 95% CI: 1.00-1.04%), respectively.ConclusionsNeisseria gonorrhoeae epidemiology in Europe has distinct and contrasting epidemiologies for vaginal sex transmission in heterosexual sex networks vs anal and oral sex transmission in MSM sexual networks. Increased transmission may facilitate drug-resistant strain emergence. Europe is far from achieving the World Health Organization target of 90% incidence reduction by 2030.

Prevalence and correlates of hazardous alcohol drinking and drug use among female sex workers and men who have sex with men in Mozambique.

BACKGROUND: Hazardous drinking and drug consumption are associated with an increased risk of HIV due to the complex interplay of factors influencing decision-making capability, stigma and social marginalization. In this study, we explore the patterns of hazardous alcohol and drug use and correlates of risk factors among female sex workers (FSW) and men who as sex with men (MSM) in Mozambique. METHODS: We conducted a secondary data analysis of bio-behavioral surveys (BBS) among FSW and MSM using a respondent-driven sampling methodology conducted in five main urban areas of Mozambique from 2019 to 20. The survey included a standardized questionnaire, where hazardous drinking was assessed (using AUDIT-C scores ≥ 4 for men, ≥ 3 for women) and drug use in the last year (FSW). Chi-squared test was used to analyze the association between socio-demographic and behavioral variables, and multivariate logistic regression measured the impact of the associated factors. RESULTS: The prevalence of hazardous alcohol drinking was 47.1% (95% CI:44.8-49.5) for FSW and 46.5 (95% CI: 44.0-49.0) for MSM. Current drug use was reported in 13.3% of FSW. FSW engaging in hazardous alcohol drinking reported more sexual partners in the last month than those no reporting hazardous alcohol use (55.3% vs. 47,1%, p < 0.001), higher rates of self-reported STIs in the last year (62,5% vs. 48,2%, p < 0.001), physical (53.5% vs. 46.7%, p < 0.0001) and sexual violence (54.7% vs. 44.2%, p < 0.001), and HIV prevalence (55.2% vs. 44.2 p < 0.001). Among MSM with hazardous alcohol drinking, there was a higher prevalence of self-reported STIs (52.8% vs. 45.4%, p < 0.001), experiences of sexual violence (18.0% vs. 8.3%, p < 0.001), and HIV prevalence (53.0% vs. 46.3%, p < 0.001). In addition, FSW who reported illicit drug use were more likely to self-reported HIV own risk (14.2% vs. 9.7%), early start sexual activity (15.4% vs. 5.3%), self-reported STIs (17.9% vs. 10.2%), and experiences of both physical (17.4% vs. 7.0%) and sexual violence (18.6% vs. 8.9%). CONCLUSION: There is an immediate need for the introduction and integration of comprehensive substance use harm mitigation and mental health interventions into HIV prevention programs, particularly those targeting key populations in Mozambique.

Water, sanitation and hygiene at sex work venues to support menstrual needs.

Introduction: Adequate menstrual health and hygiene (MHH) is necessary for women's health and equity of all menstruators. Female sex workers (FSW) require good MHH to prevent discomfort and exposure to pathogens. No studies have evaluated water, sanitation, and hygiene (WASH) conditions of FSW. We report on a cross-sectional WASH assessment at FSW venues in Kisumu, western Kenya. Methods: Stakeholders identified 77 FSW venues in Kisumu, of which 47 were randomly sampled and visited between April-May 2023. A standardized structured survey of WASH conditions was deployed by trained research staff using Android tablets after proprietor's consent. WASH scores ranging 0-3 were computed based on point each for direct observation of water available, soap available, and acceptable latrine. MHH scores ranging between 0-4 were computed (one point each) for direct observation of: currently available soap and water, locking door on a usable latrine, functional lighting, and a private area for changing clothes or menstrual materials, separate from the latrine(s). WASH and MHH scores were compared by venue type using non-parametric Kruskal-Wallis tests, and non-parametric Spearman rank tests. Results: Full WASH criteria was met by 29.8% of venues; 34.0% had no adequate WASH facilities; 46.8% had no female latrine; and 25.5% provided soap and water in private spaces for women. While 76.6% had menstrual waste disposal only 14 (29.8%) had covered bins. One in 10 venues provided adequate MHM facilities. Poorest WASH facilities were in brothels and in bars, and three-quarters of bars with accommodation had no MHH facilities. Discussion: WASH and MHH services were sub-optimal in the majority of FSW venues, preventing menstrual management safely, effectively, with dignity and privacy. This study highlights the unmet need for MHH support for this population. Poor MHH can deleteriously impact FSW health and wellbeing and compound the stigma and shame associated with their work and ability to stay clean. Acceptable and cost-effective solutions to sustainably improve WASH facilities for these populations are needed. Trial registration: Clinicaltrial.gov NCT0566678.

Exploring the syndemic interaction between social, environmental and structural contexts of HIV infection in peri-mining areas in South Africa: a qualitative study.

OBJECTIVE: To explore the syndemic interaction between social, environmental, and structural contexts and HIV infection in peri-mining areas in South Africa. DESIGN: Mixed qualitative methods consisting of in-depth interviews (IDIs) and focus group discussions (FGDs) exploring the interaction between HIV infection and the social, environmental and structural factors affecting people living in the peri-mining areas of South Africa. Themes were analysed following the syndemic theoretical framework. SETTING: Participants were recruited from three mining companies and locations in the peri-mining communities surrounding the mining companies in Limpopo, Mpumalanga, and Northern Cape provinces. PARTICIPANTS: Inclusion criteria included mineworkers, healthcare workers, female sex workers (FSWs), injection drug users (IDUs), and other community members, ≥18 years, living in the peri-mining area at the time of participation. Three FGDs were conducted (n=30): 13 men and 17 women aged 18-55 years. IDIs were conducted with 45 participants: mineworkers (n=10), healthcare workers (n=11), FSWs (n=15), truck drivers (n=4) and IDUs (n=5). RESULTS: The findings from this study indicate that a syndemic of four socio-behavioural factors is associated with HIV acquisition in peri-mining areas. These are migrancy, accessibility to alcohol and substance use, commercial and transactional sex, and uptake of HIV prevention services. CONCLUSIONS: Our findings have implications for HIV prevention programmes in mining companies, which rely on male condom usage promotion. More emphasis on better education about HIV prevalence, transmission and up-to-date prevention alternatives, such as pre-exposure prophylaxis for mineworkers is recommended. Furthermore, collaboration with community-based organisations is recommended to wholly address the syndemic factors influencing HIV transmission in peri-mining communities.

Sex Workers in Canada Face Unequal Access to Healthcare: A Systems Thinking Approach.

OBJECTIVES: Despite Canada's universal health system, sex workers across the country face an alarmingly high number of barriers when they seek to healthcare services. This has resulted in unmet healthcare needs and substantially poorer health outcomes than the general Canadian population. The objective of this study was to use a systems thinking approach to gain an in-depth understanding of the barriers sex workers face and how access could be improved. METHODS: The analysis was conducted using a systems thinking methodology, which incorporates systems tools and inquiry processes. The methodology comprised 2 domains of inquiry: (1) Problem Landscape, (2) Solutions Landscape. Systems tools and methods, such as causal loop diagrams, iceberg diagram, and systems mapping, investigated the problem landscape for understanding the interconnected nature of the issue, alongside review of both published and gray literature. An environmental scan explored the current solutions landscape. These methods connected through systemic inquiry processes, including ongoing review and application of diverse perspectives, boundary judgments, interrelationships; enabled gaps and levers of change to be determined. RESULTS: The main barriers sex workers face are stigma, criminalization, accessibility, and cost of healthcare. The stigma of sex work stems from otherization, paternalism, and moralistic, faith-based beliefs. The barriers unique to sex work are stigma and criminalization; both of which surface as avoidance, dislike, and/or fear of medical professionals. Five gaps each with a lever of change to improve access were identified: (1) Stigma - Collectivization and external collaboration, (2) Criminal status of sex work - Decriminalization, (3) Lack of adequate education - Improved healthcare professional training and anti-discriminatory health policies, (4) Lack of support - Increased community-based healthcare services, (5) Cost of healthcare - Universal coverage of "secondary" healthcare components. CONCLUSION: Through reducing the stigma surrounding sex work, making changes that improve the healthcare services that sex workers receive, and collaboration between involved parties, sex workers can be prevented from falling through the cracks of the Canadian healthcare system; lessening the health inequities sex workers face and improving their health outcomes.

Experience of social harms among female sex workers following HIV self-test distribution in Malawi: results of a cohort study.

BACKGROUND: In Malawi, female sex workers (FSW) have high HIV incidence and regular testing is suggested. HIV self-testing (HIVST) is a safe and acceptable alternative to standard testing services. This study assessed; whether social harms were more likely to be reported after HIVST distribution to FSW by peer distributors than after facility-based HIV testing and whether FSW regretted HIVST use or experienced associated relationship problems. METHODS: Peer HIVST distributors, who were FSW, were recruited in Blantyre district, Malawi between February and July 2017. Among HIVST recipients a prospective cohort was recruited. Interviews were conducted at baseline and at end-line, 3 months later. Participants completed daily sexual activity diaries. End-line data were analysed using logistic regression to assess whether regret or relationship problems were associated with HIVST use. Sexual activity data were analysed using Generalised Estimating Equations to assess whether HIVST use was temporally associated with an increase in social harms. RESULTS: Of 265 FSW recruited and offered HIVST, 131 completed both interviews. Of these, 31/131(23.7%) reported initial regret after HIVST use, this reduced to 23/131(17.6%) at the 3-month follow-up. Relationship problems were reported by 12/131(9.2%). Regret about HIVST use was less commonly reported in those aged 26-35 years compared to those aged 16-25 years (OR immediate regret-0.40 95% CI 0.16-1.01) (OR current regret-0.22 95% CI 0.07 - 0.71) and was not associated with the HIVST result. There was limited evidence that reports of verbal abuse perpetrated by clients in the week following HIVST use were greater than when there was no testing in the preceding week. There was no evidence for increases in any other social harms. There was some evidence of coercion to test, most commonly initiated by the peer distributor. CONCLUSIONS: Little evidence was found that the peer distribution model was associated with increased levels of social harms, however programmes aimed at reaching FSW need to carefully consider possible unintended consequences of their service delivery approaches, including the potential for peer distributors to coerce individuals to test or disclose their test results and alternative distribution models may need to be considered.

Biobehavioral survey using time location sampling among female sex workers living in Ghana in 2020.

Background: The HIV epidemic in Ghana is characterized as a mix of a low-level generalized epidemic with significant contributions from transmission among female sex workers (FSW) and their clients. This study seeks to identify and describe key characteristics and sexual behaviors of FSW and estimate the prevalence of HIV, syphilis, gonorrhea, chlamydia, and hepatitis B virus (HBV) among FSW in Ghana. Method: A total of 7,000 FSW were recruited for the study using Time Location Sampling (TLS) approach with 5,990 (85.6%) participants completing both biological and the behavioral aspects of the study. A structured questionnaire was administered to respondents to assess several factors, such as background characteristics, sexual risk behaviors, condom usage, HIV/AIDS knowledge, opinions, and attitudes. Trained staff conducted face-to-face interviews using mobile data collection software (REDCap) after provision of specimens for HIV and STI testing. Descriptive statistics such as medians, ranges, charts, and percentages are performed and presented. Also included, are bivariate analyses to establish relationships between FSW type and other relevant characteristics of the study. Results: Among the 7,000 (100%) FSW sampled from all regions, 6,773 took part in the behavioral and 6,217 the biological. There were 783 (11.2%) respondents who took part only in the behavioral and 227 (3.2%) only in the biological. Most were young, with a median age of 26 years, majority had never been married or were widowed/divorced and a quarter had no education or had only primary education. Majority (74.8%) of FSW first sold sex at age 25 years or less with a median age of 20 years. Most (84.8%) of the FSW indicated that they entered sex work for money, either for self or family and had an average of eleven (11) sexual partners per week. More than half (55.2%) of the FSW were new entrants who had been in sex work for less than 5 years before the study. Consistent condom use with paying clients was generally unsatisfactory (71%), and was however, very low (24%) with their intimate partners or boyfriends. Only about half (54.6%) of FSW have been exposed to HIV prevention services in the last three months preceding the survey, and this varies across regions. Overall, comprehensive knowledge about HIV and AIDS was low. Only 35% of FSW had comprehensive knowledge. HIV prevalence was 4.6% and was higher among seaters (brothel-based) and older FSW who had been sex work for a longer period. The HIV prevalence from the previous bio-behavioral survey (BBS) in 2015 and 2011 were estimated to be 6.9 and 11.1%, respectively. Conclusion: Compared to the results from the previous studies, the findings give an indication that Ghana is making significant progress in reducing the burden of HIV among FSW in the country. However, risky behaviors such as low consistent condom use, low coverage of HIV services across the regions, and low comprehensive knowledge could reverse the gains made so far. Immediate actions should be taken to expand coverage of HIV services to all locations. Efforts must be made to reach out to the new entrants while also addressing strongly held myths and misconceptions about HIV.

Causes of preventable death among children of female sex worker mothers in low- and middle-income countries: A community knowledge approach investigation.

Background: Female sex workers (FSW) in low- and middle-income countries (LMIC) are disproportionately vulnerable to poor health, social, and economic outcomes. The children of female sex workers (CFSW) experience health risks based on these challenging circumstances and the unique conditions to which they are exposed. Although country child mortality data exist, little is known about the causes of death among CFSW specifically, thereby severely limiting an effective public health response to the needs of this high-risk group of children. Methods: The Community Knowledge Approach (CKA) was employed between January and October 2019 to survey a criterion sample of 1280 FSW participants across 24 cities in eight LMIC countries. Participants meeting pre-determined criteria provided detailed reports of deaths among the CFSW within their community of peers. Newborn deaths were gleaned from FSW maternal death reports where the infants also died following birth. Results: Of the 668 child deaths reported, 589 were included in the analysis. Nutritional deficiencies comprised the leading cause of mortality accounting for 20.7% of deaths, followed closely by accidents (20.0%), particularly house fires, overdoses (19.4%), communicable diseases (18.5%), and homicides (9.8%). Other reported causes of death included neonatal conditions, respiratory illnesses, and suicides. Conclusions: The causes of CFSW death in these eight countries are preventable with improved protections. Governments, intergovernmental organisations like the United Nations, nongovernmental stakeholder organisations (e.g. sex worker organisations), and funders can implement targeted policies and programmes to protect CFSW and assist vulnerable FSW who are pregnant and raising children. Further research is needed to identify effective child welfare safeguards for CFSW.

Assessing high-risk sexual practices associated with human immunodeficiency virus infection among young female sex workers in Lubumbashi, Democratic Republic of the Congo: a cross-sectional study.

INTRODUCTION: Young female sex workers (YFSWs) face a higher risk of HIV infection compared to older workers, but there is a lack of comprehensive data on their sexual practices and HIV infection risks, which may present unique challenges and vulnerabilities. The study aimed to identify high-risk sexual practices associated with HIV infection among YFSWs in Lubumbashi. METHODS: We conducted an analytical cross-sectional study and used a comprehensive sample of all YFSWs who presented to the HIV/Sexually Transmitted Infections Screening and Treatment Center in Lubumbashi between April 2016 and December 2017. We collected data on socio-demographic characteristics and behavioral risk factors of female sex workers were collected using a structured questionnaire. Using STATA version 16, multivariate logistic regression was fitted and the results were presented as adjusted odds ratios (aORs) with their 95% confidence intervals (95% CIs). RESULTS: A total of 572 YFSWs were included in the study, 19 of whom were HIV-positive (3.3%; 95% CI: 2.1-5.1%). Participants who were forced to have sex (aOR = 12.2; 95% CI: 3.2-46.4; p < 0.0001), those who did not use condoms systematically (aOR = 4.1; 95% CI: 1.3-13.0; p = 0.018), and those who had anal sex (aOR = 23.8; 95% CI: 6.9-82.4; p < 0.0001) were more likely to be HIV-positive. CONCLUSION: The study reveals a concerning trend of higher hospital HIV prevalence among YFSWs compared to the general Congolese population. It also highlights a significant link between high-risk sexual practices and HIV infection, highlighting the need for urgent interventions.
