Abstract
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.

Prevalence of syphilis and associated factors among female sex workers in Ethiopia: findings from a multilevel analysis of a national bio-behavioral survey. BMC Public Health 2023; 23:809. [PMID: 37138265 PMCID: PMC10155315 DOI: 10.1186/s12889-023-15745-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2022] [Accepted: 04/24/2023] [Indexed: 05/05/2023] Open
Abstract
BACKGROUND Syphilis is a highly contagious sexually transmitted infection posing a significant public health challenge, especially in developing countries, including sub-Saharan Africa. Female sex workers are exposed to sexually transmitted infections, including syphilis, because of their sexual behavior and limited access to health services. However, data on national syphilis prevalence estimates and the associated factors are scarce in Ethiopia. This, as well as our limited knowledge about the extent of clustering among female sex workers in the country, is a critical gap in information we aimed to fill through this analysis. METHODS The study was a cross-sectional, bio-behavioral survey conducted among female sex workers in six cities and ten major towns in Ethiopia. Participants were selected using a respondent-driven sampling method. Survey participants provided blood samples for syphilis, HIV, and hepatitis serological testing. Survey data were collected via an interviewer-administered questionnaire. In this analysis, we employed descriptive statistics to summarize data on the study variables. In addition, we used multilevel bivariable and multivariable logistic regression models to examine the association between independent variables and the dependent variable (syphilis prevalence) while accounting for the clustering effect. RESULT A total of 6085 female sex workers participated in the survey. Their median age [Interquartile Range (IQR) was 25 (8)] years, and a majority (96.1%) were in the 20-24-year-old age group. The prevalence of syphilis among female sex workers in Ethiopia's six cities and ten major towns was 6.2%. Being in the age group of 30-34 (AOR = 2.64; 95% CI = 1.40, 4.98) and 35-59 (AOR = 4.7; 95% CI = 2.5, 8.86), being divorced/widowed (AOR = 1.37; 95% CI = 1.03, 1.82), having no formal education (AOR = 3.38; 95% CI = 2.34, 5.11), primary 1st cycle (grades 1-4) education (AOR = 2.77; 95% CI = 1.79, 4.30), and having primary 2nd cycle (grades 5-8) education (AOR = 1.80; 95% CI = 1.21, 2.69) were significantly associated with syphilis among female sex workers. CONCLUSION The prevalence of syphilis among female sex workers was high. Being divorced/widowed or in the older age group and having a low level of education were significantly associated with an increased risk of syphilis. The high prevalence and associated factors identified need to be considered in planning comprehensive interventions to control syphilis among female sex workers in Ethiopia.

Abstract
Background Stroke is a leading cause of death and chronic disability worldwide. In Sub-Saharan Africa (SSA), which includes Somalia, stroke represents a significant part of the chronic disease burden. However, there is relatively little data on risk factors, demographics, and clinical profiles. This study aimed to define the etiological, demographic characteristics, classification of stroke and functional status of patients with acute ischemic stroke (AIS) admitted to the emergency centre, and to create projections to evaluate the incidence and genetic aspects of stroke. Methods The study population consisted of patients who applied to the emergency centre between 1 May 2017 and 1 May 2021 and were diagnosed with acute ischemic stroke (AIS). Patient demographics, season of onset, risk factors, laboratory data, imaging results, infarct location, AIS subtype and treatment outcomes were collected, and compared. Results A total of 3,968 patients diagnosed with ischemia stroke were included in the study. The mean age was 51.12 ± 16.43 years, and we reported male predominance (65.7%). While hypertension, hyperlipidaemia, Diabetes mellitus (DM) were more frequent among the risk factors, smoking history and alcohol consumption history were very low. HIV-infected ischemic stroke was detected at a high rate (20.9%) and was common in a relatively young age group (31.8 ± 14.3). Large-artery atherosclerosis (LAA) subtype was detected with a high rate of 67.7%. The most common clot localization was in Supratentorial location (74.3%), and according to OSCP classification, partial anterior circulation infarcts (PACI) subtype (56.3%) was the most common. And these results were again different from other studies. Discussion While the incidence of stroke and especially HIV-associated youthful ischemic stroke continues to increase rapidly in developing countries such as Somalia, with the addition of inadequate primary health care services, stroke has become a major public health problem in African countries regarding its costs at social, psychological, and economic levels.

Abstract
OBJECTIVE Given stark health inequities among precarious and criminalized workers, we aimed to apply a structural determinants framework to systematically review evidence on HIV/sexually transmitted infection (STI) prevalence, access to HIV/STI/SRH services, and condom use among im/migrant sex workers (ISWs) globally. METHODS Systematic search of peer-reviewed studies published in English (2009-2019). Eligible studies reported HIV/STI, access to HIV/STI/SRH services, and/or condom use outcomes and/or lived experiences among ISWs. Quantitative and qualitative data were synthesized using a structural determinants framework. RESULTS Of 425 studies screened, 29 studies from 15 countries were included. HIV prevalence ranged from 0.3 to 13.6% and varied across settings, with highest prevalence among undocumented ISWs in a high-income country (Portugal). Precarious immigration status was a structural factor associated with poorer HIV/STI outcomes, whereas qualitative narratives showed ISWs' lived experiences as strongly shaped by policing and stigma. Despite disparities, in some settings, HIV and STI prevalence were lower and odds of condom use with clients were higher among ISWs relative to non-im/migrant sex workers. This review identified a paucity of research on SRH and male and gender-diverse ISWs. Across legislative settings, criminalization of SW and im/migrant status, policing, and migration-related marginalization were prominent structural barriers to ISWs' HIV/STI/SRH access. CONCLUSION This review identified important inequities and variation in HIV/STI prevalence among ISWs globally. Our findings highlight impacts of the intersections of migration and criminalization, and suggest a need to reform criminalized sex work laws; address punitive policing and immigration enforcement; enable safer indoor work environments; and expand community-based interventions towards promoting HIV/STI/SRH access and health equity among ISWs.

Abstract
In Canada, im/migrant sex workers face stigma, health access barriers, and overlapping marginalisation, with end-demand law reforms in 2014 postulated to exacerbate these inequities. Yet, little quantitative evidence on how immigration status shapes HIV/STI risk exists. Drawing on community-based longitudinal cohort data (AESHA, 2010-2018), we used multivariable confounder models with logistic regression to model (1) the independent effect of precarious immigration status (any status revocable under criminal charges: permanent residency/temporary residency/undocumented) on client condom refusal, and (2) the moderating effect of precarious status on the relationship between condom refusal and exposure to end-demand law reform (2015-2018). Over this 8-year study involving 758 sex workers in Metro Vancouver, 16.0% were im/migrants, of whom 57% had precarious immigration status at baseline. 16.5% of participants experienced client condom refusal. Precarious immigration was associated with increased odds of facing condom refusal (adjusted odds ratio [AOR] 2.53, 95% confidence interval [CI] 1.37-4.68), and these odds were heightened post-end-demand law reforms (AOR 4.35, 95%CI 1.21-15.66). Our findings suggest that lack of citizenship rights may enhance barriers to safer sex negotiation and increase HIV/STI risk among sex workers, highlighting the need for sex work and immigration policy reforms.

Abstract
Background HIV stigma and the resultant fear of being identified as HIV-positive can compromise the effectiveness of HIV programs by undermining early diagnosis and antiretroviral treatment initiation and adherence of people living with HIV (PLHIV). In the wake of the longstanding conflict in the country, little is known about the life experiences of PLHIV in Somalia. Methods A qualitative study using unstructured interviews was conducted in Somalia from September to December 2017. A convenience sampling approach was used to recruit 13 participants, including 10 persons who live with HIV and three senior officials who work for the HIV program at the Ministry of Health. Data were analyzed using a thematic analysis. Results Our findings show that PLHIV are alienated and prefer to isolate themselves due to widespread stigma subjected to them by their family members, society, employers, and health providers, which continue to undermine the scale-up of testing and treatment of PLHIV in Somalia. Consequently, they are reluctant to seek voluntary diagnosis and treatment of HIV. They often come to know about their status when their partners are found HIV positive, they are tested for other clinical purposes, or when an individual’s health deteriorates, and all other means fail to work in improving his/her situation. The study also pointed out a shortage of facilities that provide HIV diagnosis, counseling and treatment in Somalia. Conclusion Addressing stigma and discrimination subjected to PLHIV are critical to a successful HIV response in Somalia. To successfully address stigma, HIV programs need evidence on effective interventions at individual, community, and societal levels in order to strategically incorporate stigma and discrimination reduction into national HIV programs.

A comprehensive review of HIV/STI prevention and sexual and reproductive health services among sex Workers in Conflict-Affected Settings: call for an evidence- and rights-based approach in the humanitarian response. Confl Health 2017; 11:25. [PMID: 29213302 PMCID: PMC5713057 DOI: 10.1186/s13031-017-0124-y] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2016] [Accepted: 10/04/2017] [Indexed: 11/24/2022] Open
Abstract
Background While the conditions in emergency humanitarian and conflict-affected settings often result in significant sex work economies, there is limited information on the social and structural conditions of sex work in these settings, and the impacts on HIV/STI prevention and access to sexual and reproductive health (SRH) services for sex workers. Our objective was to comprehensively review existing evidence on HIV/STI prevention and access to SRH services for sex workers in conflict-affected settings globally. Methods We conducted a comprehensive review of all peer review (both epidemiological and qualitative) and grey literature published in the last 15 years (2000–2015), focusing on 1) HIV/STI vulnerability or prevention, and/or 2) access to SRH services for sex workers in conflict-affected settings. Five databases were searched, using combinations of sex work, conflict/mobility, HIV/STI, and SRH service terms. Relevant peer-reviewed and grey literature were also hand-searched, and key papers were cross-referenced for additional material. Results Five hundred fifty one records were screened and 416 records reviewed. Of 33 records describing HIV/STI prevention and/or access to SRH services among sex workers in conflict-affected settings, 24 were from sub-Saharan Africa; 18 studies described the results of primary research (13 quantitative, 3 qualitative, 2 mixed-methods) and 15 were non-primary research (e.g., commentaries, policy reports, programmatic manuals). Available evidence indicated that within conflict-affected settings, SWs’ capacity to engage in HIV/STI prevention and access SRH services is severely undermined by social and structural determinants including widespread violence and human rights violations, the collapse of livelihoods and traditional social structures, high levels of displacement, and difficulties accessing already scant health services due to stigma, discrimination and criminalization. Discussion/Conclusions This review identified significant gaps in HIV/STI and SRH research, policy, and programming for conflict-affected sex workers, highlighting a critical gap in the humanitarian response. Sex worker-informed policies and interventions to promote HIV/STI prevention and access to HIV and SRH services using a rights-based approach are recommended, and further research on the degree to which conflict-affected sex workers are accessing HIV/STI and SRH services is recommended. A paradigm shift from the behavioural and biomedical approach to a human rights-based approach to HIV/STI prevention and SRH is strongly recommended.

Abstract
Background Human Immunodeficiency Virus (HIV), syphilis, Hepatitis B Virus (HBV) and Hepatitis C Virus (HCV) are sexually transmitted infections (STIs) and share modes of transmission. These infections are generally more prevalent among female sex workers (FSWs). Methods This is a cross-sectional study conducted among female sex workers (FSWs) in Rwanda in 2015. Venue-Day-Time (VDT) sampling method was used in recruiting participants. HIV, syphilis, HBV, and HCV testing were performed. Descriptive analyses and logistic regression models were computed. Results In total, 1978 FSWs were recruited. The majority (58.5%) was aged between 20 and 29 years old. Up to 63.9% of FSWs were single, 62.3% attained primary school, and 68.0% had no additional occupation beside sex work. Almost all FSWs (81.2%) had children. The majority of FSWs (68.4%) were venue-based, and most (53.5%) had spent less than five years in sex work. The overall prevalence of syphilis was 51.1%; it was 2.5% for HBV, 1.4% for HCV, 42.9% for HIV and 27.4% for syphilis/HIV co-infection. The prevalence of syphilis, HIV, and syphilis + HIV co-infection was increasing with age and decreasing with the level of education. A positive association with syphilis/HIV co-infection was found in: 25 years and older (aOR = 1.82 [95% CI:1.33–2.50]), having had a genital sore in the last 12 months (aOR = 1.34 [95% CI:1.05–1.71]), and having HBsAg-positive test (aOR = 2.09 [1.08–4.08]). Conclusion The prevalence of HIV and syphilis infections and HIV/syphilis co-infection are very high among FSWs in Rwanda. A strong, specific prevention program for FSWs and to avert HIV infection and other STIs transmission to their clients is needed.

Abstract
OBJECTIVE Sex workers (SWs) in sub-Saharan Africa face a disproportionate HIV burden and growing concerns of severe human rights violations. Given the dearth of evidence on the burden and correlates of HIV among SWs in sub-Saharan Africa, particularly within conflict-affected settings, we examined the relationship between structural determinants (eg, war-related abduction, incarceration) and HIV infection among conflict-affected SWs in Northern Uganda. DESIGN Cross-sectional community-based research study among female SWs in conflict-affected Gulu, Northern Uganda. METHODS Interview questionnaires and voluntary HIV testing were conducted with participants recruited through SW/peer-led outreach and time-location sampling from 2011 to 2012. HIV prevalence was calculated, and bivariable and multivariable logistic regression was used to identify independent associations with HIV seroprevalence. RESULTS Of 400 SWs, 135 (33.75%) were HIV seropositive; of whom one-third were new/previously undiagnosed HIV infections. In multivariable analysis, after adjusting for age of sex work entry and education, lifetime incarceration (adjusted odds ratio: 1.93, 95% confidence interval: 1.17 to -3.20) was independently associated with HIV seroprevalence, and history of wartime abduction (adjusted odds ratio: 1.62, 95% confidence interval: 1.00 to 2.63) was marginally associated (P = 0.051). CONCLUSIONS This study documented a high rate of undiagnosed HIV infections and associations between war-related human rights violations, incarceration, and a heavy HIV burden among SWs in conflict-affected Northern Uganda. These findings highlight the serious harms of conflict and criminalization of marginalized women in sub-Saharan African contexts. SW-led interventions that address conflict experiences and policy shifts to promote a rights-based approach to HIV prevention and care remain critically needed.

[PMID: 28222772 PMCID: PMC5320666 DOI: 10.1186/s12889-017-4134-x] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2015] [Accepted: 02/14/2017] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND During the last ten years, a resurgence of syphilis has occurred in many countries worldwide, including Togo. Previous studies have shown a wide range of syphilis infection among the female sex workers (FSWs), from 1.5 to 42.1%. In Togo, Key populations, including FSWs, are rarely involved in the sentinel surveillance programs to determine the prevalence of HIV and syphilis. The aim of this study was to determine the prevalence of syphilis among female sex workers (FSWs) and their clients in Togo. METHODS We conducted a cross-sectional study in December 2011 targeting FSWs and their clients in Togo. Among participant who consented, we collected blood samples for syphilis and HIV testing. RESULTS In total, 1,836 participants (1,106 FSWs and 730 clients) were included in the survey. Their mean age was 28.6 ± 9 years. The prevalence of syphilis was 2.2% (2.2% among FSWs compare to 2.3% among their clients, p = 0.82). This prevalence was higher among FSWs over 30 years old compare to those less than 30 years old (Odd Ratio (OR) =5.03; 95% CI [1.95-13.49]). Single FSWs were three times less likely to have syphilis than those living in couple or married (OR = 3.11; CI 95% [1.16-8.83]). Brothel based or declared FSWs were 4 times more likely to be infected by syphilis than secret ones (OR = 3.89; CI 95% [1.60-9.54]). Out of the 1,836 participants of the survey, 165 (8.9%) were HIV positive. Having syphilis was associated with HIV infection (OR = 3.41; IC 95% [1.53-7.41]). CONCLUSION This study showed that: i) the prevalence of syphilis among FSWs and their clients was high; ii) syphilis was significantly associated with HIV infection. It is necessary to increase awareness campaigns and emphasize on condom use among this key population group.

Abstract
OBJECTIVES To give an overview of the HIV epidemic in the Middle East and North Africa (MENA) region. METHODS Articles on the MENA region were reviewed. RESULTS The MENA region comprises a geographically defined group of countries including both high-income, well-developed nations and low- and middle-income countries. While the annual number of new HIV infections in Sub-Saharan Africa has declined by 33% since 2005, new HIV infections in the MENA region have increased by 31% since 2001, which is the highest increase among all regions in the world. Moreover, the number of AIDS-related deaths in 2013 was estimated to be 15000, representing a 66% increase since 2005. However, the current prevalence of 0.1% is still among the lowest rates globally. There is substantial heterogeneity in HIV epidemic dynamics across MENA, and different risk contexts are present throughout the region. Despite unfavorable conditions, many countries in the region have put significant effort into scaling up their response to this growing epidemic, while in others the response to HIV is proving slower due to denial, stigma, and reluctance to address sensitive issues. CONCLUSIONS The HIV epidemic in the MENA region is still at a controllable level, and this opportunity should not be missed.

Abstract
Reporting key details of respondent-driven sampling (RDS) survey implementation and analysis is essential for assessing the quality of RDS surveys. RDS is both a recruitment and analytic method and, as such, it is important to adequately describe both aspects in publications. We extracted data from peer-reviewed literature published through September, 2013 that reported collected biological specimens using RDS. We identified 151 eligible peer-reviewed articles describing 222 surveys conducted in seven regions throughout the world. Most published surveys reported basic implementation information such as survey city, country, year, population sampled, interview method, and final sample size. However, many surveys did not report essential methodological and analytical information for assessing RDS survey quality, including number of recruitment sites, seeds at start and end, maximum number of waves, and whether data were adjusted for network size. Understanding the quality of data collection and analysis in RDS is useful for effectively planning public health service delivery and funding priorities.

Abstract
OBJECTIVES Effective healthcare systems require high-quality research to guide evidence-based interventions and strategic planning. In low- and middle-income countries, especially those emerging from violent conflict, research capacity often lags behind other aspects of health system development. Here, we sought to bibliometrically review health-related research output in Somaliland, a post-conflict self-declared, autonomous nation on the Horn of Africa, as a means of assessing research capacity. METHODS We reviewed articles on health-related research conducted in Somaliland between 1991 and 2013 that included a description of the experimental design, and articles were published in either a peer-reviewed journal or as part of a scholarly programme receiving formal review. We did not include policy or social science research that did not enrol or interact with subjects from Somaliland. Using online databases, all studies meeting minimum eligibility criteria were reviewed in regard to Somaliland-based co-authorship, topic of research and specific measures of quality. RESULTS A total of 37 studies were included in this review. Of these, only 19 (51%) included co-authorship by Somaliland-based researchers. Of the 21 studies reporting ethical approval, 16 (64%) received approval from the Somalia or Somaliland Ministry of Health, while five received approval from a university or national commission. More than two-thirds of published research was limited to a few areas of investigation with most (19, 51%) following basic cross-sectional study designs. The number of articles published per year increased from 0 to 1 in the years 1991-2007 to a maximum of 8 in 2013. CONCLUSIONS Research activity in Somaliland is extremely limited. Investigators from high-income countries have largely directed the research agenda in Somaliland; only half of the included studies list co-authors from institutions in Somaliland. Leadership and governance of health research in Somaliland is required to define national priorities, promote scholarly activity and guide the responsible conduct of research. The methods used here to assess research capacity may be generalisable to other low- and middle-income countries and post-conflict settings to measure the impact of research capacity-building efforts.

BMC Public Health 2015; 15:787.

Abstract
BACKGROUND Community mobilization among female sex workers (SWs) is recognized as an effective strategy to empower SWs and increase their uptake of health services. Activities focus on increasing social cohesion between SWs by building trust, strengthening networks, and encouraging shared efforts for mutual gain. Several studies, however, suggest that high levels of interpersonal competition between SWs can pose a barrier to collective action and support. We conducted a study to examine levels of perceived competition between SWs in Mutare, Hwange and Victoria Falls in Zimbabwe in order to inform development of a community-based intervention for HIV prevention and treatment. This paper focuses on our qualitative findings and their implications for the design of HIV programming in the Zimbabwean context. METHODS Following a respondent driven sampling (RDS) survey, we explored issues related to social cohesion amongst SWs in Mutare, Hwange and Victoria Falls through in-depth interviews conducted with 22 SWs. Interviews examined dynamics of SWs' relationships and extent of social support, and were analyzed using thematic content analysis using the constant comparative method. Findings are contextualised against descriptive data extracted from the survey, which was analysed using Stata 12, adjusting for RDS. RESULTS Across all sites, women described protecting each other at night, advising each other about violent or non-paying clients, and paying fines for each other following arrest. In Mutare, women gave additional examples, including physically attacking problem clients, treatment adherence support and shared saving schemes. However, interviews also highlighted fierce competition between women and deep mistrust. This reflects the reported mix of competition and support from the survey of 836 women (Mutare n = 370, Hwange n = 237, Victoria Falls n = 229). In Mutare, 92.8 % of SWs agreed there was a lot of competition; 87.9 % reported that SWs support each other. This contrasted with Victoria Falls and Hwange where fewer agreed there was competition between SWs (70.5 % and 78.0 %), but also fewer reported that SWs support each other at work (55.2 % and 51.2 %). CONCLUSIONS Women reported being most likely to support each other when confronted with serious danger but maintained high levels of competition for clients, suggesting competition at work does not represent a barrier to support. Examples of practical assistance between SWs provide entry points for our planned community mobilization activities, which aim to broaden trust and support among SWs while acknowledging their professional competition.

Abstract
Sex work occurs in many forms and sex workers of all genders have been affected by HIV epidemics worldwide. The determinants of HIV risk associated with sex work occur at several levels, including individual biological and behavioural, dyadic and network, and community and social environmental levels. Evidence indicates that effective HIV prevention packages for sex workers should include combinations of biomedical, behavioural, and structural interventions tailored to local contexts, and be led and implemented by sex worker communities. A model simulation based on the South African heterosexual epidemic suggests that condom promotion and distribution programmes in South Africa have already reduced HIV incidence in sex workers and their clients by more than 70%. Under optimistic model assumptions, oral pre-exposure prophylaxis together with test and treat programmes could further reduce HIV incidence in South African sex workers and their clients by up to 40% over a 10-year period. Combining these biomedical approaches with a prevention package, including behavioural and structural components as part of a community-driven approach, will help to reduce HIV infection in sex workers in different settings worldwide.

Abstract
Sexual violence is pervasive in eastern Democratic Republic of Congo (DRC). Survivors of sexual violence encounter numerous challenges, and women with a sexual violence-related pregnancy (SVRP) face even more complex sequelae. Because of the stigma associated with SVRP, there is no conventional sampling frame and, therefore, a paucity of research on SVRP outcomes. Respondent-driven sampling (RDS), used to study this "hidden" population, uses a peer recruitment sampling system that maintains strict participant privacy and controls and tracks recruitment. If RDS assumptions are met and the sample attains equilibrium, sample weights to correct for biases associated with traditional chain referral sampling can be calculated. Questionnaires were administered to female participants who were raising a child from a SVRP and/or who terminated a SVRP. A total of 852 participants were recruited from October 9, 2012, to November 7, 2012. There was rapid recruitment, and there were long referral chains. The majority of the variables reached equilibrium; thus, trends established in the sample population reflected the target population's trends. To our knowledge, this is the first study to use RDS to study outcomes of sexual violence. RDS was successfully applied to this population and context and should be considered as a sampling methodology in future sexual violence research.

Abstract
OBJECTIVE to investigate knowledge on sexually transmitted diseases (STDs), STD-related risk behaviors, and signs/symptoms of STDs among female sex workers (FSWs). METHODS a cross-sectional study was conducted with a probabilistic sample comprising 395 women recruited using a respondent-driven sampling method between 2009 and 2010. The data were collected during face-to-face interviews. RESULTS most of the participants were young adults, had a low educational level, and had poor knowledge on the transmission paths of the human immunodeficiency virus (HIV). Over one-third of the participants were not able to describe the signs/symptoms of STDs. The prevalence rates of vaginal discharge and wounds/ulcers were 49.0% and 8.6%, respectively, but 41.7% of the women had not sought treatment. CONCLUSION the results indicate the need for public health policies focusing on the control and prevention of STDs in this population, especially for the FSWs who are active in an important prostitution and sex tourism route in central Brazil.

Abstract
The aim of the paper is to provide an overview of HIV case reporting data for the year 2011 from the countries of the World Health Organization Eastern Mediterranean Region (WHO EMR). Fourteen countries provided data for the year 2011 and reported a total of 4263 HIV cases of which 66.8% were men. The highest number of reported HIV cases in men per 100,000 population was in Oman (5.8), Somalia (5.5) and Iran (3.3), while in women in Somalia (7.6), Oman (3.9) and Morocco (2.4). In the majority of the countries, the most common reported mode of transmission was heterosexual. This could be due to under-reporting of male-to-male transmission and more frequent testing of men than women.

Abstract
Treatment of sexually transmitted infections (STIs) has been hypothesised to decrease HIV transmission. Although observational studies show an association between STIs and HIV, only one prospective randomised controlled trial (RCT) has confirmed this. Female genital schistosomiasis can cause genital lesions, accompanied by bloody discharge, ulcers or malodorous discharge. Genital schistosomiasis is common, starts before puberty and symptoms can be mistaken for STIs. Three observational studies have found an association between schistosomiasis and HIV. Genital lesions that develop in childhood are chronic. This paper sought to explore the possible effects of schistosomiasis on the RCTs of STI treatment for HIV prevention. In the study sites, schistosomiasis was a likely cause of genital lesions. The studies recruited women that may have had genital schistosomal lesions established in childhood. Schistosomiasis endemic areas with different prevalence levels may have influenced HIV incidence in intervention and control sites differently, and some control group interventions may have influenced the impact of schistosomiasis on the study results. Schistosomiasis is a neglected cause of genital tract disease. It may have been an independent cause of HIV incidence in the RCTs of STI treatment for HIV prevention and may have obscured the findings of these trials.

Abstract
OBJECTIVES To determine the prevalence of HIV and related behavioural risks among Iranian female sex workers (FSW) via the first national biobehavioural surveillance survey. METHODS In 2010, 1005 FSW were approached and 872 recruited using facility-based sampling from 21 sites in 14 cities in Iran. We collected dried blood samples and conducted face-to-face interviews using a standardised questionnaire. Data were weighted based on the response rate and adjusted for the clustering effect of the sampling site. Adjustment was performed by weighting based on the sampling fraction of each site using a prior estimate of its total size of the FSW population. RESULTS The prevalence of HIV infection (95% CI) was 4.5% (2.4 to 8.3) overall, 4.8% (2.2 to 9.8) among those who had reported a history of drug use and 11.2% (5.4 to 21.5) among those who had a history of injection drug use. The frequencies of condom use in the last sexual act with paying clients and non-paying partners were 57.1% and 36.3%, respectively. Any drug use was reported by 73.8% of participants, and among this subgroup, 20.5% had a history of injection drug use. CONCLUSIONS The prevalence of HIV was considerable among FSW particularly those who had a history of drug injection. A combination of prevention efforts addressing unsafe sex and injection are needed to prevent further transmission of HIV infection.

Abstract
OBJECTIVES To provide an overview of the current level of development and results from the national HIV surveillance systems of the 23 countries of the Middle East and North Africa (MENA), and to assess the quality of HIV surveillance systems in the period 2007-2011. METHODS A questionnaire was used to collect the information about the structure, activities and the results of HIV surveillance systems from the National AIDS Programmes. Assessment of the quality was based on four indicators: timeliness of data collection, appropriateness of populations under surveillance, consistency of the surveillance sites and groups measured over time, and coverage of the surveillance system. RESULTS Only in four countries did surveillance systems enable assessment of epidemic trends in the same populations and locations over time, such as in pregnant women (Morocco, Iran), injecting drug users (Iran, Pakistan), female sex workers (Djibouti, Morocco) and male sex workers (Pakistan). There is increasing evidence of HIV infection being firmly established in at least one of the populations most at risk of HIV in nine MENA countries, while lower risk populations show elevated HIV prevalence in South Sudan, Djibouti and some parts of Somalia. CONCLUSIONS The performance of HIV surveillance systems in several of the MENA countries has improved in recent years. The extent of HIV epidemics in the populations most at risk of HIV is still largely unknown in 10 countries. Multiple data sources that most of the countries still lack would enable indirectly estimation not only of the patterns of HIV epidemics but also the effectiveness of HIV responses.

Abstract
Objective(S) To determine the HIV prevalence and extent of engagement with HIV prevention and care among a representative sample of Zimbabwean sex workers working in Victoria Falls, Hwange and Mutare. Design Respondent driven sampling (RDS) surveys conducted at each site. Methods Sex workers were recruited using respondent driven sampling with each respondent limited to recruiting 2 peers. Participants completed an interviewer-administered questionnaire and provided a finger prick blood sample for HIV antibody testing. Statistical analysis took account of sampling method. Results 870 women were recruited from the three sites. HIV prevalence was between 50 and 70%. Around half of those confirmed HIV positive were aware of their HIV status and of those 50-70% reported being enrolled in HIV care programmes. Overall only 25-35% of those with laboratory-confirmed HIV were accessing antiretroviral therapy. Among those reporting they were HIV negative, 21-28% reported having an HIV test in the last 6 months. Of those tested HIV negative, most (65-82%) were unaware of their status. Around two-thirds of sex workers reported consistent condom use with their clients. As in other settings, sex workers reported high rates of gender based violence and police harassment. Conclusions This survey suggests that prevalence of HIV is high among sex workers in Zimbabwe and that their engagement with prevention, treatment and care is sub-optimal. Intensifying prevention and care interventions for sex workers has the potential to markedly reduce HIV and social risks for sex workers, their clients and the general population in Zimbabwe and elsewhere in the region.

Abstract
Objectives To assess HIV and syphilis prevalence, HIV-related behaviours and testing for HIV in female sex workers (FSW) in Sudan. Design Bio-behavioural surveys using respondent-driven sampling were carried out among FSW in the capital cities of 14 states in Sudan in 2011–2012. HIV and syphilis testing was done by rapid tests. Results 4220 FSW aged 15–49 years were recruited. The median age of recruited women varied from 21 to 28 years per site. The highest HIV prevalence was measured at two sites in the eastern zone (5.0% and 7.7%), while in the other zones it ranged from 0% to 1.5%. Syphilis prevalence ranged from 1.5% in the northern zone to 8.9% in the eastern zone. Ever having been tested for HIV was reported by 4.4%–23.9% of FSW across all sites. Condom use at last sex with a client varied from 4.7% to 55.1%, while consistent condom use with clients in the month preceding the surveys was reported by 0.7%–24.5% of FSW. The highest reporting of ever injecting drugs was measured at a site in the western zone (5.0%). Conclusions The surveys’ findings indicate that the highest burden of HIV in FSW is in the eastern states of the country. Condom use and HIV testing data demonstrate the need for HIV interventions that should focus on HIV testing and risk reduction strategies that include stronger condom promotion programmes in FSW and their clients.

Abstract
As a concentrated epidemic, human immunodeficiency virus (HIV) is spreading rapidly in one or more groups in Iran, but in the general population its prevalence is relatively low. Female sex workers (FSWs) and their partners are at greater risk for HIV infection. To determine the prevalence of HIV and sexually transmitted infections (STIs) including gonorrhoea, Chlamydia, herpes simplex type 2 and syphilis among FSWs. We conducted a cross-sectional study of 278 FSWs in Shiraz, by using respondent-driven sampling, from June to March 2010. The recruitment chain started with 14 seeds, and FSWs were tested for HIV, syphilis, herpes simplex type 2, gonorrhoea and Chlamydia. HIV prevalence was 4.7% (13/278); the most prevalent STI was herpes simplex type 2, 9.7% (27/278), followed by Chlamydia 9% (25/278), gonorrhoea 1.4% (4/278) and syphilis (0/278). The FSWs reported drug use (69.9%) of which 16.4% had history of injecting drug use. Unprotected sex in the past month was reported by 24.4% of FSWs. Urgent education and risk reduction programmes are needed in this population.

Abstract
BACKGROUND Female sex workers are a population who are at heightened risk of HIV infection secondary to biological, behavioural, and structural risk factors. However, three decades into the HIV pandemic, understanding of the burden of HIV among these women remains limited. We aimed to assess the burden of HIV in this population compared with that of other women of reproductive age. METHODS We searched PubMed, Embase, Global Health, SCOPUS, PsycINFO, Sociological Abstracts, CINAHL (Cumulative Index to Nursing and Allied Health Literature), Web of Science, and POPLine for studies of female sex workers in low-income and middle-income countries published between Jan 1, 2007, and June 25, 2011. Studies of any design that measured the prevalence or incidence of HIV among female sex workers, even if sex workers were not the main focus of the study, were included. Meta-analyses were done with the Mantel-Haenszel method with a random-effects model characterising an odds ratio for the prevalence of HIV among female sex workers compared with that for all women of reproductive age. FINDINGS Of 434 selected articles and surveillance reports, 102 were included in the analyses, representing 99,878 female sex workers in 50 countries. The overall HIV prevalence was 11·8% (95% CI 11·6-12·0) with a pooled odds ratio for HIV infection of 13·5 (95% CI 10·0-18·1) with wide intraregional ranges in the pooled HIV prevalence and odds ratios for HIV infection. In 26 countries with medium and high background HIV prevalence, 30·7% (95% CI 30·2-31·3; 8627 of 28,075) of sex workers were HIV-positive and the odds ratio for infection was 11·6 (95% CI 9·1-14·8). INTERPRETATION Although data characterising HIV risk among female sex workers is scarce, the burden of disease is disproportionately high. These data suggest an urgent need to scale up access to quality HIV prevention programmes. Considerations of the legal and policy environments in which sex workers operate and actions to address the important role of stigma, discrimination, and violence targeting female sex workers is needed.

Abstract
BACKGROUND HIV prevalence is low in the Middle East and North Africa (MENA) region, though the risk or potential for further spread in the future is not well understood. Behavioral surveys are limited in this region and when available have serious limitations in assessing the risk of HIV acquisition. We demonstrate the potential use of herpes simplex virus-2 (HSV-2) seroprevalence as a marker for HIV risk within MENA. METHODS We designed a mathematical model to assess whether HSV-2 prevalence can be predictive of future HIV spread. We also conducted a systematic literature review of HSV-2 seroprevalence studies within MENA. RESULTS We found that HSV-2 prevalence data are rather limited in this region. Prevalence is typically low among the general population but high in established core groups prone to sexually transmitted infections such as men who have sex with men and female sex workers. Our model predicts that if HSV-2 prevalence is low and stable, then the risk of future HIV epidemics is low. However, expanding or high HSV-2 prevalence (greater than about 20%), implies a risk for a considerable HIV epidemic. Based on available HSV-2 prevalence data, it is not likely that the general population in MENA is experiencing or will experience such a considerable HIV epidemic. Nevertheless, the risk for concentrated HIV epidemics among several high-risk core groups is present. CONCLUSIONS HSV-2 prevalence surveys provide a useful mechanism for identifying and corroborating populations at risk for HIV within MENA. HSV-2 serology offers an effective tool for probing hidden sexual risk behaviors in a region where quality behavioral data are limited.
