Sex work is an indisputable reality in humanitarian settings. UNHCR and UNFPA have demonstrated the importance of multi-sectoral interventions to address HIV in sex work. Adapted from the source document.

Introduction: Virtually no African country provides HIV prevention services in sex work settings with an adequate scale and intensity. Uncertainty remains about the optimal set of interventions and mode of delivery. Methods: We systematically reviewed studies reporting interventions for reducing HIV transmission among female sex workers in sub-Saharan Africa between January 2000 and July 2011. Medline (PubMed) and non-indexed journals were searched for studies with quantitative study outcomes. Results: We located 26 studies, including seven randomized trials. Evidence supports implementation of the following interventions to reduce unprotected sex among female sex workers: peer-mediated condom promotion, risk-reduction counselling and skills-building for safer sex. One study found that interventions to counter hazardous alcohol-use lowered unprotected sex. Data also show effectiveness of screening for sexually transmitted infections (STIs) and syndromic STI treatment, but experience with periodic presumptive treatment is limited. HIV testing and counselling is essential for facilitating sex workers' access to care and antiretroviral treatment (ART), but testing models for sex workers and indeed for ART access are little studied, as are structural interventions, which create conditions conducive for risk reduction. With the exception of Senegal, persistent criminalization of sex work across Africa reduces sex workers' control over working conditions and impedes their access to health services. It also obstructs health-service provision and legal protection. Conclusions: There is sufficient evidence of effectiveness of targeted interventions with female sex workers in Africa to inform delivery of services for this population. With improved planning and political will, services - including peer interventions, condom promotion and STI screening - would act at multiple levels to reduce HIV exposure and transmission efficiency among sex workers. Initiatives are required to enhance access to HIV testing and ART for sex workers, using current CD4 thresholds, or possibly earlier for prevention. Services implemented at sufficient scale and intensity also serve as a platform for subsequent community mobilization and sex worker empowerment, and alleviate a major source of incident infection sustaining even generalized HIV epidemics. Ultimately, structural and legal changes that align public health and human rights are needed to ensure that sex workers on the continent are adequately protected from HIV

Abstract Background Female sex workers (FSWs) experience high levels of sexual and reproductive health (SRH) morbidity, violence and discrimination. Successful SRH interventions for FSWs in India and elsewhere have long prioritised community mobilisation and structural interventions, yet little is known about similar approaches in African settings. We systematically reviewed community empowerment processes within FSW SRH projects in Africa, and assessed them using a framework developed by Ashodaya, an Indian sex worker organisation. Methods In November 2012 we searched Medline and Web of Science for studies of FSW health services in Africa, and consulted experts and websites of international organisations. Titles and abstracts were screened to identify studies describing relevant services, using a broad definition of empowerment. Data were extracted on service-delivery models and degree of FSW involvement, and analysed with reference to a four-stage framework developed by Ashodaya. This conceptualises community empowerment as progressing from (1) initial engagement with the sex worker community, to (2) community involvement in targeted activities, to (3) ownership, and finally, (4) sustainability of action beyond the community. Results Of 5413 articles screened, 129 were included, describing 42 projects. Targeted services in FSW 'hotspots' were generally isolated and limited in coverage and scope, mostly offering only free condoms and STI treatment. Many services were provided as part of research activities and offered via a clinic with associated community outreach. Empowerment processes were usually limited to peer-education (stage 2 of framework). Community mobilisation as an activity in its own right was rarely documented and while most projects successfully engaged communities, few progressed to involvement, community ownership or sustainability. Only a few interventions had evolved to facilitate collective action through formal democratic structures (stage 3). These reported improved sexual negotiating power and community solidarity, and positive behavioural and clinical outcomes. Sustainability of many projects was weakened by disunity within transient communities, variable commitment of programmers, low human resource capacity and general resource limitations. Conclusions Most FSW SRH projects in Africa implemented participatory processes consistent with only the earliest stages of community empowerment, although isolated projects demonstrate proof of concept for successful empowerment interventions in African settings. ; Peer Reviewed

AbstractIntroductionSisters with a Voice (Sisters), a programme providing community‐led differentiated HIV prevention and treatment services, including condoms, HIV testing, pre‐exposure prophylaxis (PrEP) and antiretroviral therapy linkage for sex workers, reached over 26,000 female sex workers (FSW) across Zimbabwe in 2020. Zimbabwe's initial Covid "lockdown" in March 2020 and associated movement restrictions interrupted clinical service provision for 6 weeks, particularly in mobile clinics, triggering the adaptation of services for the Covid‐19 context and a scale up of differentiated service delivery (DSD) models. PrEP service delivery decentralized with shifts from clinical settings towards community/home‐based, peer‐led PrEP services to expand and maintain access. We hypothesize that peer‐led community‐based provision of PrEP services influenced both demand and supply‐side determinants of PrEP uptake. We observed the effect of these adaptations on PrEP uptake among FSW accessing services in Sisters in 2020.MethodsNew FSW PrEP initiations throughout 2020 were tracked by analysing routine Sisters programme data and comparing it with national PrEP initiation data for 2020. We mapped PrEP uptake among all negative FSW attending services in Sisters alongside Covid‐19 adaptations and shifts in the operating environment throughout 2020: prior to lockdown (January–March 2020), during severe restrictions (April–June 2020), subsequent easing (July–September 2020) and during drug stockouts that followed (October–December 2020).Results and discussionPrEP uptake in 2020 occurred at rates <25% (315 initiations or fewer) per month prior to the emergence of Covid‐19. In response to Covid‐19 restrictions, DSD models were scaled up in April 2020, including peer demand creation, community‐based delivery, multi‐month dispensing and the use of virtual platforms for appointment scheduling and post‐PrEP initiation support. Beginning May 2020, PrEP uptake increased monthly, peaking at an initiation rate of 51% (n = 1360) in September 2020. Unexpected rise in demand coincided with national commodity shortages between October and December 2020, resulting in restriction of new initiations with sites prioritizing refills.ConclusionsDespite the impact of Covid‐19 on the Sisters Programme and FSW mobility, DSD adaptations led to a large increase in PrEP initiations compared to pre‐Covid levels demonstrating that a peer‐led, community‐based PrEP service delivery model is effective and can be adopted for long‐term use.

AbstractIntroductionUNAIDS' goal of ending AIDS by 2030 is unreachable without better targeting of testing, prevention and care. Female sex workers (FSW) in Zimbabwe are at high risk of HIV acquisition and transmission. Here, we report on collated programme and research data from Zimbabwe's national sex work programme. We also assess the potential for wider population impact of FSW programmes by modelling the impact on HIV incidence of eliminating transmission through FSW (i.e. calculate the population attributable fraction of incidence attributable to sex work).MethodsDescriptive analyses of individual‐level programme data collected from FSW between 2009 and June 2018 are triangulated with data collected through 37 respondent driven sampling surveys from 19 sites in Zimbabwe 2011 to 2017. We describe programme coverage, uptake, retention and patterns of sex work behaviour and gaps in service provision. An individual‐level stochastic simulation model is used to reconstruct the epidemic and then the incidence compared with the counter‐factual trend in incidence from 2010 had transmission through sex work been eliminated from that date.ResultsSisters has reached >67,000 FSW since 2009, increasing attendance as number of sites, programme staff and peer educators were increased. Over 57% of all FSW estimated to be working in Zimbabwe in 2017 (n = 40,000) attended the programme at least once. The proportion of young FSW reached has increased with introduction of the "Young Sisters programme." There are no clear differences in pattern of sex work across settings. Almost all women report condom use with clients at last sex (95%); however, consistent condom use with clients in the last month varies from 52% to 95% by site. Knowledge of HIV‐positive status has increased from 48 to 78% between 2011 and 2016, as has prevalence of ART use among diagnosed women (29 to 67%). Although subject to uncertainty, modelling suggests that 70% (90% range: 32%, 93%) of all new infections in Zimbabwe from 2010 are directly or indirectly attributable to transmission via sex work.ConclusionsIt is feasible to increase coverage and impact of sex work programming through community‐led scale‐up of evidence‐based interventions. Eliminating transmission through commercial sex would likely have a substantial impact on new infections occurring more widely across Zimbabwe.
