Abstract
The study investigates the statistical relationship between male circumcision and HIV prevalence in Africa, in the context of the Voluntary Medical Male Circumcision (VMMC) campaigns in place since 2008. Data from the Population-based HIV Impact Assessment (PHIA) surveys conducted in African countries in 2017-2018 were utilized. Six countries with high HIV prevalence, low traditional circumcision and large VMMC programs were selected: Eswatini, Lesotho, Malawi, Namibia, Zambia, Zimbabwe. The statistical analysis investigated the relative risk (RR) of HIV prevalence by circumcision status (circumcised vs intact) among men age 20-59, and the age-incidence of HIV in the two groups among men age 20-49, defined as the linear-logistic slope of the relationship between prevalence and age. Results show that the standardized RR was not different from 1 at older ages (50-59): RR = 0.923, 95% CI = 0.769-1.108, P = 0.390. Furthermore, the age-incidence was at least as high or higher among the circumcised groups than among the intact groups. The standardized RR was lower than 1 at younger ages, and this could be explained by selection biases. HIV prevalence at age 40-59 (27.3%) was also the same in the four groups of circumcision status (intact, traditional, medical, unknown). Results matched earlier observations made in South Africa that circumcised and intact men had similar levels of HIV infection. The study questions the current strategy of large scale VMMC campaigns to control the HIV epidemic. These campaigns also raise a number of ethical issues.

Meeting the reproductive health needs of female sex workers in Côte d'Ivoire: protecting the human right to dignified health. Reprod Health 2023; 20:133.

Abstract
The sexual and reproductive health needs of female sex workers (FSW) are often understudied and underserved in the context of HIV-related research in countries across Sub-Saharan Africa and West Africa. We assessed the lived experiences of FSW across Côte d'Ivoire to characterize unmet reproductive health needs and opportunities to address them. From February-August, 2020, ENDA Santé, Côte d'Ivoire conducted 75 in-depth interviews and 15 focus group discussions with FSW and community informants in five cities in Côte d'Ivoire. Themes that emerged included the inconsistent use of contraception services, a history of unintended pregnancies, and experiences of stigma at public healthcare facilities. Opportunities to increase the impact of both SRH and HIV services included strengthening existing HIV and family planning service integration for FSW. Taken together, the results highlight the importance of addressing the unmet reproductive health needs of FSW to both optimize the HIV response and increase the delivery of human-rights affirming sexual and reproductive health services for sex workers.

Screening for Resistant Bacteria, Antimicrobial Resistance Genes, Sexually Transmitted Infections and Schistosoma spp. in Tissue Samples from Predominantly Vaginally Delivered Placentae in Ivory Coast and Ghana. Pathogens 2023; 12:999. [PMID: 37623959 PMCID: PMC10459482 DOI: 10.3390/pathogens12080999] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2023] [Revised: 07/27/2023] [Accepted: 07/28/2023] [Indexed: 08/26/2023] Open
Abstract
Medical complications during pregnancy have been frequently reported from Western Africa with a particular importance of infectious complications. Placental tissue can either become the target of infectious agents itself, such as, e.g., in the case of urogenital schistosomiasis, or be subjected to contamination with colonizing or infection-associated microorganisms of the cervix or the vagina during vaginal delivery. In the retrospective cross-sectional assessment presented here, the quantitative dimension of infection or colonization with selected resistant or pathogenic bacteria and parasites was regionally assessed. To do so, 274 collected placental tissues from Ivory Coastal and Ghanaian women were subjected to selective growth of resistant bacteria, as well as to molecular screening for beta-lactamase genes, Schistosoma spp. and selected bacterial causative agents of sexually transmitted infections (STI). Panton-Valentine-negative methicillin-resistant Staphylococcus aureus (MRSA) was grown from 1.8% of the tissue samples, comprising the spa types t008 and t688, as well as the newly detected ones, t12101 (n = 2) and t12102. While the culture-based recovery of resistant Enterobacterales and nonfermentative rod-shaped Gram-negative bacteria failed, molecular assessments confirmed beta-lactamase genes in 31.0% of the samples with multiple detections of up to four resistance genes per sample and blaCTX-M, blaIMP, blaGES, blaVIM, blaOXA-58-like, blaNDM, blaOXA-23-like, blaOXA-48-like and blaKPC occurring in descending order of frequency. The beta-lactamase genes blaOXA-40/24-like, blaNMC_A/IMI, blaBIC, blaSME, blaGIM and blaDIM were not detected. DNA of the urogenital schistosomiasis-associated Schistosoma haematobium complex was recorded in 18.6% of the samples, but only a single positive signal for S. mansoni with a high cycle-threshold value in real-time PCR was found. Of note, higher rates of schistosomiasis were observed in Ghana (54.9% vs. 10.3% in Ivory Coast) and Cesarean section was much more frequent in schistosomiasis patients (61.9% vs. 14.8% in women without Schistosoma spp. DNA in the placenta). Nucleic acid sequences of nonlymphogranuloma-venereum-associated Chlamydia trachomatis and of Neisseria gonorrhoeae were recorded in 1.1% and 1.9% of the samples, respectively, while molecular attempts to diagnose Treponema pallidum and Mycoplasma genitalium did not lead to positive results. Molecular detection of Schistosoma spp. or STI-associated pathogens was only exceptionally associated with multiple resistance gene detections in the same sample, suggesting epidemiological distinctness. In conclusion, the assessment confirmed considerable prevalence of urogenital schistosomiasis and resistant bacterial colonization, as well as a regionally expected abundance of STI-associated pathogens. Continuous screening offers seem advisable to minimize the risks for the pregnant women and their newborns.

Abstract
INTRODUCTION Sexual and reproductive health problems are one of the top five risk factors for disability in the developing world. The rates of sexual health problems in most African countries are overwhelming, which is why HIV and other STIs are still such a challenge in sub-Saharan Africa. Talking about sex in most African countries is a taboo, leading to common myths and misconceptions that ultimately impact community sexual health. METHODS In this study, we conducted 11 key stakeholder individual interviews with community, religious, political, and health leaders (sexual health stakeholders) in Tanzania. Qualitative content analysis was used to analyze all the materials. RESULTS Two main categories merged from the analysis. The first category, "Ambiguities about sexual health" focused on societal and political misconceptions and identified ten myths or misconceptions common in Tanzania. Stakeholders highlighted the confusion that happens when different information about sexual health is presented from two different sources (e.g., community leaders/peers and political leaders), which leaves the community and community leaders unsure which one is reliable. The second category, "Practical dilemmas in serving clients", addressed a range of professional and religious dilemmas in addressing sexual health concerns. This included the inability of religious leaders and health care providers to provide appropriate sexual health care because of internal or external influences. CONCLUSION Myths and misconceptions surrounding sexual health can prevent communities from adequately addressing sexual health concerns, and make it more difficult for healthcare providers to comfortably provide sexual health care to patients and communities. Stakeholders affirmed a need to develop a sexual health curriculum for medical, nursing and midwifery students because of the lack of education in this area. Such a curriculum needs to address nine common myths which were identified through the interviews.

Abstract
BACKGROUND The World Health Organization (WHO) recommends periodic gonorrhoea prevalence assessments in the general population or proxies thereof (including pregnant women, women attending family planning clinics, military recruits, and men undergoing employment physicals for example) and in population groups at increased risk, including men-who-have-sex-with-men (MSM) and sex workers. METHOD We evaluated reported prevalence data, including estimates from proxy general population samples to reflect the WHO recommendations. We describe the outcomes from the general population country-by-country and extend previous reviews to include MSM, sex workers, and extragenital infections. RESULT AND CONCLUSION In our systematic search, 2015 titles were reviewed (January 2010-April 2019) and 174 full-text publications were included. National, population-based prevalence data were identified in only four countries (the United States of America, the United Kingdom, Peru, New Caledonia) and local population-based estimates were reported in areas within five countries (China, South Africa, Brazil, Benin, and Malawi). The remaining studies identified only reported test positivity from non-probability, proxy general population samples. Due to the diversity of the reviewed studies, detailed comparison across studies was not possible. In MSM, data were identified from 64 studies in 25 countries. Rectal infection rates were generally higher than urogenital or pharyngeal infection rates, where extragenital testing was conducted. Data on sex workers were identified from 41 studies in 23 countries; rates in female sex workers were high. Current prevalence monitoring was shown to be highly suboptimal worldwide. Serial prevalence monitoring of critical epidemiological variables, and guidelines to optimize prevalence study conduct and reporting beyond antenatal settings are recommended.

Abstract
Purpose Female sex workers play an important role in transmitting HIV and syphilis from high-risk groups to the general population. However, epidemic trends and risk factors for syphilis in Chinese female sex workers (FSWs) remain unclear. Methods Using convenient sampling methods, 2482 FSWs were interviewed and tested for syphilis from 2014 to 2019, all of them were divided into two groups of high-grade FSWs and low-grade FSWs according to service solicited and clients price there were. Demographic data were collected and logistic regression analysis was used to identify risk factors for syphilis. Results 43.67% of participants have received free condoms, 76.15% of them engaged in peer education of the 2482 FSWs tested for syphilis, 107 (4.31%) were positive. The prevalence of syphilis in high-grade FSWs was significantly lower than that in low-grade FSWs (3.14% and 5.62%, respectively).The overall prevalence of syphilis increased from 3.19% to4.47%. The percentage of FSWs received free condoms and engaged in peer education increased significantly. With upgraded awareness of syphilis, the number of FSWs having protected sex also increased significantly. It is also found that low-grade female sex workers are at greater risk of syphilis than those high-grade ones (odds ratio (OR) = 1.76, 95% CI 1.18–2.63, p < 0.05). Conclusion Great awareness of syphilis and the increased utilization of condom did not reduce the prevalence of syphilis, especially in low-grade FSWs group. More effective integrated interventions should be developed for such populations.

Abstract
Female sex workers (FSW) in Malawi have among the highest HIV prevalence estimates worldwide. Daily oral pre-exposure prophylaxis (PrEP) is an effective HIV prevention method, yet preferences for PrEP delivery among FSW are lacking. Eight focus group discussions, a literature review, and cognitive interviews were conducted to identify modifiable PrEP delivery attributes and inform discrete-choice experiment (DCE) development for FSW in Lilongwe. Enrolled FSW received an interviewer-assisted DCE. Data were analyzed using mixed logit regression. Dispensing location was most preferred, followed by the provision of additional services. Women preferred receiving PrEP at family planning clinics or non-governmental organization run drop-in centers. Cervical cancer screening was the most preferred additional service, while pregnancy testing and partner risk reduction counseling were less valued. This study was the first study to examine PrEP delivery preferences in Malawi using DCE-a powerful elicitation tool to apply to other key populations at risk for HIV.

Abstract
Although the HIV epidemic is generalized in West Africa, some population groups such as men who have sex with men (MSM), especially those engaged in transactional sex (TS), are thought to be particularly more vulnerable to HIV than others. However, few data are available to help identify their health-related needs with a view to implementing targeted prevention interventions. To fill this knowledge gap, we aimed to characterize MSM reporting TS (MSM-TS) and to identify factors associated with their sexual practices using data from the prospective cohort study CohMSM, which was conducted in Burkina Faso, Côte d’Ivoire, Mali and Togo. Three stigmatization sub-scores were constructed (experienced, perceived and internalized). The generalized estimating equation method was used for data analysis. Of the total 630 HIV-negative MSM recruited in CohMSM, 463, 410 and 244 had a follow-up visit at 6, 12 and 18 months, respectively. In a total of 1747 follow-up visits, 478 TS encounters were reported by 289 MSM-TS (45.9%). Of the latter, 91 regularly reported TS (31.5%), 55 (19.0%) stopped reporting TS after baseline, and 53 (18.3%) reported TS after baseline and 90 (31.1%) occasionally reported TS. The following variables, regarding the previous 6 months, were positively associated with TS: being younger (aOR[95%CI]:1.86[1.39–2.50]), less educated (aOR[95%CI]:1.49[1.09–2.03]), unmarried status (aOR[95%CI]:1.79[1.10–2.93]), satisfaction with current sex life (aOR[95%CI]:1.41[1.06–1.88]), group sex with men (aOR[95%CI]:2.07[1.46–2.94]), multiple male sexual partners (aOR[95%CI]:1.85[1.40–2.44]), receptive or versatile anal sex with male partners (aOR [95%CI]:1.48[1.12–1.96]), giving benefits in exchange for sex with a man (aOR[95%CI]:2.80[1.97–3.98]), alcohol consumption (aOR[95%CI]:1.44[1.08–1.93]) and drug use (aOR[95%CI]:1.82[1.24–2.68]) during sex, and finally experiencing stigmatization (aOR [95%CI]:1.15[1.07–1.25]). Condom use during anal sex (aOR[95%CI]:0.73[0.53–0.99]) was negatively associated with TS.

[PMID: 31191036 PMCID: PMC6529623 DOI: 10.2147/hiv.s196085] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2018] [Accepted: 04/24/2019] [Indexed: 11/27/2022] Open
Abstract
Objectives: Female sex workers (FSW) are highly at risk of HIV, and can potentially transmit the human immunodeficiency virus (HIV) in different societies. Study design: The aims of the present study were to investigate the prevalence of HIV/AIDS and associated risk factors among FSW between 2010 and 2017 using a systematic literature review and meta-analysis approach. Methods: International databases were searched, including ISI Web of Science, Embase, PubMed, and Scopus. Using the appropriate keywords, relevant studies published on the HIV/AIDS prevalence among FSW between 2010 and 2017 were identified. Afterwards, the information was extracted and analyzed by STATA version 14. Results: Thirty-seven studies were found eligible for inclusion in this research, encompassing a total of 46,657 subjects. The results revealed that the global prevalence of HIV/AIDS among FSW was 2.17 (95% CI=1.37-3.14). Conclusion: These findings demonstrated the high prevalence of HIV/AIDS among FSWs worldwide. Accordingly, strict educational and interventional programs should be implemented globally to reduce HIV/AIDS prevalence among this group, as well as to prevent probable HIV transmission.

BMC Infect Dis 2019; 19:61. [PMID: 30654762 PMCID: PMC6337801 DOI: 10.1186/s12879-019-3698-8] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2018] [Accepted: 01/09/2019] [Indexed: 12/02/2022] Open
Abstract
Background Chlamydia trachomatis and Neisseria gonorrhoeae are the most common pathogens causing genital tract infections. Female commercial sex workers (FCSWs) are the key population to be affected by sexually transmitted infections (STIs). In Ethiopia, little is known about C. trachomatis and N. gonorrhoeae infections in most at risk population. Therefore, this study aimed to assess the prevalence of these bacterial STIs among FCSWs. Methods A cross-sectional study was conducted at the confidential clinic in Hawassa City, Southern Ethiopia from January to April, 2017. A total of 338 FCSWs were selected using systematic random sampling technique and enrolled in the study. Information about socio-demography and associated factors was collected using structured questionnaires. Endocervical swab samples were also collected from the study participants and tested for C. trachomatis using rapid immunochromatography assay. Samples were also cultured to isolate N. gonorrhoeae according to the standard bacteriological method. Results The prevalence of N. gonorrhoeae and C. trachomatis among FCSWs was 3.3% [95% confidence interval (CI): 1.5–5.3] and 6.8% (95% CI: 3.9–9.5), respectively. FCSWs who consistently practiced sex without condom in the last 6 months had 6.3 times (AOR 6.3; 95% CI 1.61–24.86, P = 0.008), and 4.0 times (AOR 4.0; 95% CI 1.06–15.31, p = 0.040) higher odds of acquiring N. gonorrhoeae and C. trachomatis infections, respectively. Conclusion The observed rates of C. trachomatis and N. gonorrhoeae infections among FCSWs warrant the need to strengthen intervention efforts. In this regard, screening FCSWs for the specified infections and improving the practice of condom use would be important.

Abstract
Classification of professional and non-professional female sex workers (FSWs) into different categories, never previously reported in the Central African Republic (CAR), may be useful to assess the dynamics of the human immunodeficiency virus (HIV) epidemic, design operational intervention programmes to combat HIV and other sexually transmitted infections (STIs) and to adapt these programmes to the broad spectrum of sexual transactions in the CAR. Our study proposes a socio-behavioural classification of FSWs living in the CAR and engaged in transactional and commercial sex. Thus, the aims of the study were these: (i) to categorize FSWs according to socio-anthropologic criteria in Bangui and (ii) to examine the association between a selection of demographic and risk variables with the different categories of female sex work as an outcome. A cross-sectional questionnaire survey was conducted in 2013 to describe the spectrum of commercial sex work (CSW) in Bangui among 345 sexually active women having more than 2 sexual partners, other than their regular partner, during the prior 3 months and reporting to have received money or gifts in return for their sexual relationships. According to socio-behavioural characteristics, FSWs were classified into six different categories. Professional FSWs, constituting 32.5% of the interviewed women, were divided in two categories: pupulenge (13.9%), i.e., dragonflies (sometimes called gba moundjou, meaning literally look at the White) consisting of roamers, who travel around the city to hotels and nightclubs seeking wealthy clients, with a preference for French men; and the category of kata (18.6%), i.e., FSWs working in poor neighbourhoods. Non-professional FSWs, constituting 67.5% of the interviewed women, were divided into four categories: street and market vendors (20.8%), students (19.1%), housewives (15.7%) and unskilled civil servants (11.9%). In general, CSW in the CAR presents a remarkably heterogeneous phenomenon. Risk-taking behaviour regarding STI/HIV infection appears to be different according to the different categories of female CSW. The groups of katas and street vendors were poorer and less educated, consumed more alcohol or other psycho-active substances (cannabis, tramadol and glue) and, consequently, were more exposed to STI. Our results emphasise the high level of vulnerability of both poor professional FSWs (kata) and non-professional sex workers, especially street vendors, who should be taken into account when designing prevention programmes targeting this population for STI/HIV control purposes.

Abstract
Female sex workers (FSWs) continue to carry a heavy burden of sexually transmitted infections (STI). For prevention purposes, there is a need to identify most-at-risk subgroups among them. The objective of this longitudinal cohort study conducted at Dispensaire IST, Cotonou, Benin, was to assess Neisseria gonorrhoeae (NG) / Chlamydia trachomatis (CT) incidence and determinants; and HIV incidence among FSWs in presence of STI/HIV risk reduction activities. Overall, 319 adult FSWs were followed quarterly from September 2008 to March 2012. NG/CT were detected from endocervical swabs by Amplified DNA Assays employing Strand displacement amplification technology. HIV testing was done on capillary blood using two consecutive rapid diagnostic tests. Anderson-Gill proportional hazard models (HR) were used to determine factors independently associated with NG/CT incidence. The majority of FSWs were HIV-negative (188, 58.9%). There were 6 HIV seroconversions among these 188 HIV-negative women. HIV incidence (95% Confidence interval, CI) was 1.41 (0.28–2.54) seroconversions per 100 person-years at risk (PYAR): 6 events / 425.1 PYAR. Sixty-two out of 319 women experienced 83 new episodes of NG/CT for an overall incidence rate (95% CI) of 10.8 (8.17–13.88) events / 100 PYAR. From month-24 onwards, HIV-positive women (treated: HR (95%CI): 4.2 (1.60–10.77); untreated: HR (95%CI): 4.2 (1.59–11.49) were more likely to acquire NG/CT compared to HIV-negative FSWs. Longer duration in sex work (>2 years: HR; 95%CI: 0.4 (0.22–0.72)) was protective against NG/CT. Refusal by clients (55.8%) was the main reason for non-condom use. Enrolling women from one clinic (Dispensaire IST) may have impaired generalizability of the findings. New NG/CT/HIV infections were observed among FSWs notwithstanding ongoing prevention interventions. To eliminate HIV transmission among FSWs, STI/HIV control programs need to promote women’s empowerment and address vulnerability to infection of HIV-positive FSWs.

Abstract
Chlamydia trachomatis and Neisseria gonorrhoeae constitute major public health problems among women, but the burden of infection in sub-Saharan Africa is poorly documented. We conducted a structured review of the prevalence and incidence of genital, oral and anal C. trachomatis and N. gonorrhoeae infection in women in sub-Saharan Africa. We searched Medline, EMBASE and Web of Science over a 10-year period for studies on epidemiology of genital, oral and anal chlamydial infection and gonorrhoea in women in all countries of sub-Saharan Africa. We assessed geographic and demographic differences in prevalence and incidence of infection; weighted mean prevalence estimates were calculated with a random-effect model. A total of 102 study results were included, with data available for 24/49 of sub-Saharan countries. The weighted prevalence of chlamydial infection was lower among women in community-based studies (3.9%; 95% CI: 2.9-5.1%) than for women recruited at primary healthcare facilities (6.0%; 95% CI: 4.2-8.4%, p < 0.001); the same was observed for gonorrhoea (2.2%; 95% CI: 1.2-4.0% vs. 4.2%; 95% CI: 3.2-5.6%, p < 0.001). Prevalence of Chlamydia among sex workers was 5.5% (95% CI: 4.2-7.3%) and gonorrhoea 7.6% (95% CI: 5.4-11%). Seven studies reported on incidence which varied between 0.75-28 and 2.8-17 per 100 person-years-at-risk for chlamydial infection and gonorrhoea, respectively. Only two studies reported on anal infections and one on oral infection. This overview underscores the considerable incidence and prevalence of genital C. trachomatis and N. gonorrhoeae in women in different settings in sub-Saharan Africa. Better control strategies are warranted to reduce the burden of infection and to prevent long-term complications of these infections.

Abstract
Current evidence suggests that anal intercourse (AI) during sex work is common in sub-Saharan Africa, but there have been few studies in which the contribution of heterosexual AI to human immunodeficiency virus (HIV) epidemics has been investigated. Using a respondent-driven sampling survey of female sex workers (FSWs; n = 466) in Abidjan, Côte d'Ivoire, in 2014, we estimated AI prevalence and frequency. Poisson regressions were used to identify AI determinants. Approximately 20% of FSWs engaged in AI during a normal week (95% confidence interval: 15, 26). Women who performed AI were generally younger, had been selling sex for longer, were born in Côte d'Ivoire, and reported higher sex-work income, more frequent sex in public places, and violence from clients than women not reporting AI. Condom use was lower, condom breakage/slippage more frequent, and use of water-based lubricants was less frequently reported for AI than for vaginal intercourse. Using a dynamic transmission model, we estimated that 22% (95% credible interval: 11, 37% of new HIV infections could have been averted among FSWs during 2000-2015 if AI had been substituted for vaginal intercourse. Despite representing a small fraction of all sex acts, AI is an underestimated source of HIV transmission. Increasing availability and uptake of condoms, lubricants, and pre-exposure prophylaxis for women engaging in AI could help mitigate HIV risk.

Abstract
Nepalese labor migrants and their wives are considered as at-risk populations for HIV infection. There may be a risk of HIV transmission from the labor migrant and their wives to the general population due to HIV-related risk behaviors, but so far empirical evidence to support this hypothesis is scarce. Therefore, this study was conducted to compare HIV-related risk behaviors between labor migrants, their wives, and males and females from the general population in the far-western region of Nepal. This was a cross-sectional study, in which structured face-to-face interviews were conducted with 261 male labor migrants, 262 wives of labor migrants, 123 males and 122 females from the general population. We found that the proportion of the labor migrants and their wives reporting having had extramarital sex in the previous year did not differ significantly with the males (11.9 vs. 13.4 %, p value 0.752) and females (2.0 vs. 1.7 %, p value 0.127) from the general population. However, the labor migrants compared with the males from the general population were 1.51 times and the wives of labor migrants compared with the females from the general population were 2.37 times more likely to have been tested for HIV. Both the males from the general population and the labor migrants are equally engaged in unprotected extramarital sex. Therefore, it is recommended that the prevention programs, including access to condoms and HIV testing, should be scaled up targeting a broader range of individuals in the far-western region of Nepal.

Abstract
Background Female sex workers (FSWs) are considered a vulnerable population for HIV infection and a priority for HIV/AIDS response programs. This study aimed to determine HIV prevalence among FSWs in five cities in Burkina Faso. Methods FSWs aged 18 and older were recruited using respondent driven sampling (RDS) in five cities (Ouagadougou, Bobo-Dioulasso, Koudougou, Ouahigouya, and Tenkodogo) in Burkina Faso from 2013 to 2014. HIV testing was performed using the HIV testing national algorithm. We conducted bivariate and multivariate logistic regression analysis to assess correlates of HIV in all cities combined (not RDS-adjusted). Results Among Ouagadougou, Koudougou, and Ouahigouya FSWs, RDS-adjusted HIV prevalence was 13.5% (95% Confidence Interval [CI]: 9.6-18.7), 13.3% (95% CI: 7.6-22.4), and 13.0% (95% CI: 7.6-21.3), respectively, compared to 30.1% (95% CI: 25.5-35.1) among Bobo-Dioulasso FSWs. Factors associated with HIV infection were age (adjusted odds ratio [aOR] = 7.84 95% CI: 3.78-16.20), being married or cohabitating (aOR = 2.43, 95% CI: 1.31-4.49), and history of pregnancy (aOR = 5.24, 95% CI: 1.44-18.97). Conclusion These results highlight the need to strengthen HIV prevention among FSWs, through behavior change strategies, and improve access to sexual and reproductive health services.

Abstract
Objective The aims of the study were i) to categorize female sex workers (FSW) according to socio-anthropologic criteria in Bangui; ii) to examine the association between a selection of demographic and risk variables with the different categories of female sex work as outcome, and iii) to investigate factors associated with HIV status. Methods A cross-sectional questionnaire survey was conducted to describe the spectrum of commercial sex work in Bangui among 345 sexually active women. After collection of social and behavioral characteristics, each woman received a physical examination and a blood sample was taken for biological analyses, including HIV testing. The relationships between sociodemographic characteristics, behavioral variables involved in high risk for HIV as well as biological results were investigated by bivariate analysis in relationship with FSW categories as main outcomes, and by bivariate analysis followed by multivariate logistic regression analysis in relationship with HIV as the main outcome. The strength of statistical associations was measured by crude and adjusted Odds ratios (OR) and their 95% confidence intervals. Results The typology of FSW comprised six different categories. Two groups were the “official” professional FSW primarily classified according to their locations of work [i) “kata“(18.55%) representing women working in poor neighborhoods of Bangui; ii) “pupulenge” (13.91%) working in hotels and night clubs to seek white men]. Four groups were “clandestine” nonprofessional FSW classified according to their reported main activity [i) “market and street vendors” (20.86%); ii) “schoolgirls or students” (19.13%) involved in occasional transactional sex (during holidays); iii) “housewives or unemployed women” (15.65%); iv) “civil servants” (11.88%) working as soldiers or in the public sector]. The overall prevalence of HIV-1 was 19.12% (66/345). HIV varied according to FSW categories. Thus, among professional FSW, the HIV prevalence was 6-fold higher in "kata" than "pupulenge" (39.13% versus 6.30%; P = 0.001). Among nonprofessional FSW, the "vendors" showed the highest HIV prevalence (31.91%), which was higher than in "students" (6.10%; P = 0.001), "civil servants" (9.83%; P = 0.005), and "housewives" (13.00%; P = 0.01). In bivariate analysis, the following variables showed statistically significant association with risk for HIV infection: nationality; age of first sexual intercourse; self-assessment of HIV risk; knowledge of HIV status; anal sex practice with last clients; irregular condom use in last week; consumption of alcohol; other psycho-active substances; past history of STIs; HBs Ag; HSV-2 and bacterial vaginosis. However, the variable “sex workers categories” dichotomized into professional versus nonprofessional FSW was no longer associated with HIV. In multivariate logistical regression analysis, HIV infection was strongly associated with nationality (15.65% versus 3.77%) [adjusted OR (aOR) 3.39: 95% CI:1.25–9.16, P<0.05]; age of first sexual intercourse (21.10% versus 14.00%) (aOR 2.13: 95% CI: 1.03–4.39, P<0.05); anal sex practice with last clients (43.40% versus 11.50%) (aOR 4.31: 95% CI:2.28–8.33, P<0.001); irregular condom use in past week (33.50% versus 3.00%) (aOR 5.49: 95% CI:1.89–15.98, P<0.001); alcohol consumption before sex (34.70% versus 7.80%) (aOR 2.69: 95% CI:1.22–4.96, P<0.05); past history of STIs (41.00% versus 10.80%) (aOR 2.46: 95% CI:1.22–4.97, P<0.05) and bacterial vaginosis (29.80% versus 4.29%) (aOR 6.36: 95% CI: 2.30–17.72, P<0.001). Conclusion Our observations highlight the high level of vulnerability for HIV acquisition of both poor professional “kata” and nonprofessional “street vendor” FSW categories. These categories should be particularly taken into account when designing specific prevention programs for STIs/HIV control purposes.

Changing Dynamics of HIV Transmission in Côte d'Ivoire: Modeling Who Acquired and Transmitted Infections and Estimating the Impact of Past HIV Interventions (1976-2015). J Acquir Immune Defic Syndr 2017; 75:517-527.

Abstract
INTRODUCTION Understanding the impact of past interventions and how it affected transmission dynamics is key to guiding prevention efforts. We estimated the population-level impact of condom, antiretroviral therapy (ART), and prevention of mother-to-child transmission activities on HIV transmission and the contribution of key risk factors on HIV acquisition and transmission. METHODS An age-stratified dynamical model of sexual and vertical HIV transmission among the general population, female sex workers (FSW), and men who have sex with men was calibrated to detailed prevalence and intervention data. We estimated the fraction of HIV infections averted by the interventions, and the fraction of incident infections acquired and transmitted by different populations over successive 10-year periods (1976-2015). RESULTS Overall, condom use averted 61% (95% credible intervals: 56%-66%) of all adult infections during 1987-2015 mainly because of increased use by FSW (46% of infections averted). In comparison, ART prevented 15% (10%-19%) of adult infections during 2010-2015. As a result, FSW initially (1976-1985) contributed 95% (91%-97%) of all new infections, declining to 19% (11%-27%) during 2005-2015. Older men and clients mixing with non-FSW are currently the highest contributors to transmission. Men who have sex with men contributed ≤4% transmissions throughout. Young women (15-24 years; excluding FSW) do not transmit more infections than they acquired. CONCLUSIONS Early increases in condom use, mainly by FSW, have substantially reduced HIV transmission. Clients of FSWs and older men have become the main source of transmission, whereas young women remain at increased risk. Strengthening prevention and scaling-up of ART, particularly to FSW and clients of female sex workers, is important.

Abstract
OBJECTIVE To report on the results of three size estimations of the populations of female sex workers (FSW) in five cities in Côte d'Ivoire and on operational lessons learned, which may be relevant for key population programmes in other parts of the world. METHODS We applied three methods: mapping and census, capture-recapture and service multiplier. All were applied between 2008 and 2009 in Abidjan, San Pedro, Bouaké, Yamoussoukro and Abengourou. RESULTS Abidjan was the city with the highest number of FSW by far, with estimations between 7880 (census) and 13 714 (service multiplier). The estimations in San Pedro, Bouaké and Yamoussoukro were very similar, with figures ranging from 1160 (Yamoussoukro, census) to 1916 (San Pedro, capture-recapture). Important operational lessons were learned, including strategies for mapping, the importance of involving peer sex workers for implementing the capture-recapture and the identification of the right question for the multiplier method. CONCLUSIONS Successful application of three methods to estimate the population size of FSW in five cities in Côte d'Ivoire enabled us to make recommendations for size estimations of key population in low-income countries.

Population-level impact of an accelerated HIV response plan to reach the UNAIDS 90-90-90 target in Côte d'Ivoire: Insights from mathematical modeling. PLoS Med 2017; 14:e1002321. [PMID: 28617810 PMCID: PMC5472267 DOI: 10.1371/journal.pmed.1002321] [Citation(s) in RCA: 31] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/22/2016] [Accepted: 05/09/2017] [Indexed: 12/27/2022] Open
Abstract
BACKGROUND National responses will need to be markedly accelerated to achieve the ambitious target of the Joint United Nations Programme on HIV/AIDS (UNAIDS). This target aims for 90% of HIV-positive individuals to be aware of their status, for 90% of those aware to receive antiretroviral therapy (ART), and for 90% of those on treatment to have a suppressed viral load by 2020, with each individual target reaching 95% by 2030. We aimed to estimate the impact of various treatment-as-prevention scenarios in Côte d'Ivoire, one of the countries with the highest HIV incidence in West Africa, with unmet HIV prevention and treatment needs, and where key populations are important to the broader HIV epidemic. METHODS AND FINDINGS An age-stratified dynamic model was developed and calibrated to epidemiological and programmatic data using a Bayesian framework. The model represents sexual and vertical HIV transmission in the general population, female sex workers (FSW), and men who have sex with men (MSM). We estimated the impact of scaling up interventions to reach the UNAIDS targets, as well as the impact of 8 other scenarios, on HIV transmission in adults and children, compared to our baseline scenario that maintains 2015 rates of testing, ART initiation, ART discontinuation, treatment failure, and levels of condom use. In 2015, we estimated that 52% (95% credible intervals: 46%-58%) of HIV-positive individuals were aware of their status, 72% (57%-82%) of those aware were on ART, and 77% (74%-79%) of those on ART were virologically suppressed. Reaching the UNAIDS targets on time would avert 50% (42%-60%) of new HIV infections over 2015-2030 compared to 30% (25%-36%) if the 90-90-90 target is reached in 2025. Attaining the UNAIDS targets in FSW, their clients, and MSM (but not in the rest of the population) would avert a similar fraction of new infections (30%; 21%-39%). A 25-percentage-point drop in condom use from the 2015 levels among FSW and MSM would reduce the impact of reaching the UNAIDS targets, with 38% (26%-51%) of infections averted. The study's main limitation is that homogenous spatial coverage of interventions was assumed, and future lines of inquiry should examine how geographical prioritization could affect HIV transmission. CONCLUSIONS Maximizing the impact of the UNAIDS targets will require rapid scale-up of interventions, particularly testing, ART initiation, and limiting ART discontinuation. Reaching clients of FSW, as well as key populations, can efficiently reduce transmission. Sustaining the high condom-use levels among key populations should remain an important prevention pillar.

Mukumbang FC. Actions of female sex workers who experience male condom failure during penetrative sexual encounters with clients in Cape Town: Implications for HIV prevention strategies. South Afr J HIV Med 2017; 18:698. [PMID: 29568633 PMCID: PMC5843032 DOI: 10.4102/sajhivmed.v18i1.698] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2016] [Accepted: 02/05/2017] [Indexed: 01/22/2023] Open
Abstract
Background Condom failure has always been found to coexist with condom usage, especially among sex workers. Objective To describe the actions of female sex workers when they are faced with situations of condom failure. Methods Using the survey design, the participants were selected through the snowball sampling method. Their responses were obtained using a structured questionnaire. A total of 100 questionnaires were analysed. Results With respect to the immediate actions of sex workers after condom failure, 36% of the respondents continued with the sexual encounter after noticing that the condom was broken. Another 36% stopped immediately when they noticed that the condom had failed, but replaced the condom; 13% of the participants stopped the sexual encounter completely; 3% applied vaginal spermicidal foam; and 5% of the respondents stopped immediately and took a douche when they had the chance. For the actions within the next 24 hours of experiencing condom failure with a client, 53% of the participants did nothing; 4% sought counsel from a professional; 3% of the respondents took alcohol or drugs to forget the incident, 25% went to the clinic for assistance and 8% offered other responses. Conclusion While continuing the sexual encounter without replacing the condom, taking alcohol and drugs or doing nothing could increase the risk of contracting HIV; however, actions like stopping the sexual encounter completely and visiting a clinic or a professional could make a difference between staying HIV negative or seroconverting. There is a need for targeted intervention to address issues of inappropriate behaviours after experiencing condom failure.

Abstract
BACKGROUND HIV diagnosis, the first step in HIV care and treatment engagement, may be inhibited by substance use among female sex workers (FSW). We assessed the relationship between alcohol and cannabis use and lack of HIV infection awareness among HIV-infected FSW in Lilongwe, Malawi. METHODS From July to September, 2014, 200 FSW aged ≥18 years were enrolled using venue-based sampling to examine substance use, HIV testing history, and serostatus ascertained by HIV rapid test. We used Poisson regression with robust variance estimates to estimate the associations of alcohol and cannabis use and lack of HIV infection awareness. RESULTS Of the 138 HIV-infected FSW, 20% were unaware of their HIV infection, with 70% not testing within 6 months prior. According to the Alcohol Use Disorder Identification Tests (AUDIT), 55% of FSW unaware of their HIV infection reported hazardous, harmful, or dependent alcohol consumption. We observed a dose-response relationship between alcohol use and lack of HIV infection awareness, with alcohol dependency significantly associated with lack of HIV infection awareness (adjusted prevalence ratio: 3.0, 95% CI: 1.3, 6.8). Current cannabis use was uncommon (26%) among unaware HIV-infected FSW and weakly associated with lack of HIV infection awareness adjusted prevalence ratio: 1.1, 95% CI: 0.5, 2.5). CONCLUSION Increased levels of alcohol use is associated with lack of HIV infection awareness among HIV-infected FSW in Malawi. Frequent, consistent HIV testing integrated with alcohol reduction strategies could improve the health and infection awareness of substance-using FSW.

Abstract
BACKGROUND The number of people who use drugs (PWUD) has dramatically increased in West Africa over the last 15 years, but targeted interventions are falling behind, notably because of the lack of awareness of the health needs of PWUD. We aimed to assess prevalence and factors associated with HIV and other infections in PWUD in Abidjan, Ivory Coast, one of the countries most affected by HIV in Western Africa. METHODS We used respondent-driven-sampling to obtain a representative sample of heroin or cocaine/crack users aged 18 years or more. Socio-behavioral data were obtained by face-to-face questionnaires. Blood samples were collected and tested for HIV. Two sputa were obtained in tuberculosis (TB) symptomatic participants for acid-fast-bacilli (AFB) smear testing. After a descriptive analysis, crude prevalence were calculated, then weighted to take account of the sampling method. Factors associated with HIV and TB were studied using adjusted log-binomial regression. Population size was estimated by capture-recapture. RESULTS 450 PWUD were recruited in May 2014. The mean age was 33.5 years; 10.9% were women. Smoking was the main mode of consumption, ever injecting was reported by 12.7% of the participants (3.6% in the past month). Sex work was reported by 15.8% of the PWUD (13.7% of the men), and 10.2% of the men reported sexual relationships with other men (MSM). We found a weighted prevalence of 9.5% for HIV. Women were 3.4 times more likely to be infected than men. Among men, being a sex worker (SW) (adjusted OR 2.9 [95CI 1.06-7.98]) or MSM (adjusted OR 11.5 [95CI 4.22-31.42]) were the main factors associated with HIV infection in adjusted analysis. Injection was not associated with HIV. TB weighted prevalence was 1.8%, associated with poor living arrangements in adjusted analysis. We estimated that 3521; 95CI 3049-3993 PWUD live in Abidjan. CONCLUSION PWUD in Abidjan are at high risk of HIV due to sexual transmission, especially in women, SW and MSM who also use drugs. Interventions should be developed to improve HIV prevention and linkage to care in these specific populations. More generally, improving the health of PWUD involves a broader reflection on the living environment and access to health care of slum residents in large African cities.

Abstract
OBJECTIVE To readjust HIV control programmes in Africa, we assessed the factors associated with high-risk behaviours and HIV infection among young female sex workers (FSW) in Burkina Faso. METHODS We carried out a cross-sectional study from September 2009 to September 2010 in Ouagadougou, the capital city. FSW were categorised as professionals and part-time sex workers (PTSW). After a face-to-face questionnaire, blood and urine samples were collected for HIV, HSV-2, genital infections and pregnancy. High-risk behaviour was defined as a recent unprotected sex with either casual clients, regular clients or regular partners. RESULTS We recruited 609 FSW including 188 (30.9%) professionals. Their median age was 21 years (IQR 19-23), and the prevalence of HIV was 10.3% among professionals and 6.5% among PTSW. Only 3 of 46 HIV-infected women were aware of their status. Overall, 277 (45.6%) women reported high-risk behaviours (41.2% among professionals and 47.5% among PTSW), which were driven mainly by non-systematic condom use with regular partners. In multivariable analysis, PTSW (adjusted OR (AOR)=1.89; 95% CI 1.27 to 2.82) and having a primary (AOR=1.75; 95% CI 1.15 to 2.67) or higher education level (AOR=1.80; 95% CI 1.13 to 2.89) remained associated with high-risk behaviours. HIV infection was associated with older age (AOR=1.44; 95% CI 1.22 to 1.71), with being married/cohabiting (AOR=2.70; 95% CI 1.21 to 6.04) and with Trichomonas vaginalis infection (AOR=9.63; 95% CI 2.93 to 31.59), while history of HIV testing was associated with a decreased risk (AOR=0.18; 95% CI 0.08 to 0.40). CONCLUSIONS This study highlights the need for targeted interventions among young FSW focusing particularly on PTSW, sexual behaviours with regular partners and regular HIV testing.

Abstract
OBJECTIVE The HIV care continuum among female sex workers (FSW), a key population, has not been well characterized, especially within the generalized epidemics of sub-Saharan Africa. This was the first study to characterize the HIV care continuum among FSW in Lilongwe, Malawi. METHODS From July through September 2014, we used venue-based sampling to enroll 200 adult FSW in Lilongwe, Malawi into a cross-sectional evaluation assessing HIV care continuum outcomes. Seropositive FSW, identified using HIV rapid testing, received rapid CD4 counts in addition to viral loads using dried blood spots. We calculated proportions of HIV-infected FSW who had history of care, were on ART, and had suppressed viral load and we used Poisson regression to estimate the associations of demographic characteristics and transmission risk behaviors with each outcome. RESULTS HIV seroprevalence was 69% (n = 138). Among all FSW the median age was 24 years (IQR: 22-28). Among the 20% who were newly diagnosed and reported previously testing negative, the median time since last HIV test was 11 months (interquartile range: 3-17). The majority (69%) of HIV-infected FSW had a history of HIV care, 52% reported current ART use, and 45% were virally suppressed. Of the FSW who reported current ART use, 86% were virally suppressed. Transmission risk behaviors were not associated with continuum outcomes. CONCLUSIONS FSW in Lilongwe were predominately young and have a high HIV prevalence. Only half of HIV-infected FSW reported current ART use, but the majority of those on ART were virally suppressed. To reduce ongoing transmission and improve health outcomes, increased HIV testing, care engagement, and ART coverage is urgently needed among FSW. Universal testing and treatment strategies for all FSW in Malawi must be strongly considered.

BMC Oral Health 2015; 15:154. [PMID: 26631015 PMCID: PMC4668627 DOI: 10.1186/s12903-015-0129-0] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2015] [Accepted: 10/29/2015] [Indexed: 01/19/2023] Open
Abstract
BACKGROUND Worldwide, female sex workers (FSW) represent a vulnerable population for oral diseases due to many risk factors including HIV infection and drug abuse. In sub-Saharan Africa, little is known about the burden of oral diseases and their determinants in vulnerable populations. The aim of the study was to estimate the prevalence and associated factors of oral diseases among FSW. METHODS A cross sectional study was conducted among FSW who attended a dedicated non-profit clinic in Abidjan, Côte d'Ivoire from June to August 2013. Data about the presence of dental caries, periodontitis and oral-mucosal lesions were collected by a dentist during an oral examination. Behavioural information related to oral hygiene habits as well as tobacco and alcohol consumption were collected through a standardized questionnaire. Information related to HIV infection including HIV diagnosis, last known CD4 count and antiretroviral therapy were documented through a medical chart review. Logistic regression models were used to identify factors associated with oral diseases. RESULTS A total of 249 FSW with a median age of 29 years, [Inter Quartile Range (IQR) = 23-36] and a median duration of sex work of 24 months [IQR 9-60]) were included. Current tobacco use and hazardous alcohol use were reported in 21.7 % and 19.7 % of FSW, respectively. The estimated prevalence of HIV infection was 33.7 % [95 % confidence interval (CI); 27.8 - 39.6]) and 82.1 % of HIV-infected FSW were on antiretroviral therapy . The prevalence of dental caries, periodontitis and oral-mucosal lesions were 62.3 % [95 % CI 55.5 - 67.5], 14.5 % [95 % CI 10.2 - 18.9] and 8.2 % [95 % CI 4.8 - 11.5], respectively. In multivariate analysis, periodontitis, oral-mucosal lesions and HIV infection were associated with odds ratio of 2.6 [95 % CI, 1.2-5.8]) and 50.0 [95 % CI; 6.4-384.6]. CONCLUSIONS This study showed a high prevalence of oral diseases among FSW in Abidjan. HIV infection was common and significantly associated with periodontal diseases and oral-mucosal lesions. There is a need to integrate regular screening and treatment of oral lesions into the medical follow-up of FSW along with strategies for HIV prevention.

Abstract
BACKGROUND Neisseria gonorrhoeae (N. gonorrhoeae) is one of the most prevalent non-ulcerative sexually transmitted infections (STIs) in China, however, the data about N. gonorrhoeae infections are limited in this population. The objective of this study is to determine N. gonorrheae incidence and associated risk factors among female sex workers (FSWs) in China. METHODS This serial cross-sectional study was conducted semi-annually among FSWs in a City of Yunnan Province, which constituted an open cohort study. Participants were interviewed and tested for N. gonorrhoeae every 6 months. RESULTS During 3 years of follow-up, 64 incident cases of N. gonorrhoeae infection were diagnosed, yielding an overall incidence of 5.9 per 100 person years (PY) (95% confidence interval (CI), 4.53-7.41). Working in higher risk commercial sex venue (adjusted hazard ratio (AHR)=2.7, 95% CI, 1.56-4.55), inconsistently used condoms with clients in previous week (AHR=1.9, 95% CI, 1.07-3.35) and being infected with C. trachomatis (AHR=1.9, 95% CI, 1.06-3.26) were independent risk factors for incident N. gonorrhoeae infection. CONCLUSIONS A relatively high prevalence and incidence of N. gonorrhoeae among a prospective cohort of FSWs underscore the urgency for traditional HIV/STIs prevention methods among FSWs, such as condom promotion, screening and treatment of STIs, considering the high prevalence of STIs. Significant attention should focus on FSWs working in higher risk commercial sex venues as they are at higher risk for N. gonorrhoeae and transmission than those in lower risk commercial sex venues.

Abstract
BACKGROUND Antiretroviral therapy (ART) for HIV-infected sex workers is an important HIV prevention strategy. However, sex workers may have additional challenges for retention in ART care. The objectives of this study were to assess retention of sex workers on ART in a routine setting in Ivory Coast and identify risk factors for loss to follow-up (LTFU). METHODS The design was a retrospective cohort study. An analysis of clinic files was conducted in 2 sites providing ART services to sex workers in Ivory Coast. Demographic, behavior, and clinical data of female and male sex workers on ART were abstracted onto a standardized anonymous data collection form. Data collection took place between May 11 and 28, 2010. RESULTS A total of 376 female and 38 male sex workers were included in the analysis. The retention probability was 75% at 6 months, 68% at 12 months, 55% at 24 months, and 47% at 36 months. Attrition was mainly because of LTFU. Factors significantly associated with LTFU in bivariate analysis were lower schooling level, later calendar year of starting ART, and not receiving initial adherence counseling. Later year of starting ART and not receiving adherence counseling at ART initiation remained significantly associated with LTFU in a multivariate Cox regression model. CONCLUSIONS To improve the retention of sex workers on ART, there is a need for more in-depth investigation of the role of pre-ART counseling and the increasing rates of LTFU with each calendar year.

Abstract
OBJECTIVE To identify gaps in epidemiologic and HIV service coverage data for key populations (KP), including men who have sex with men (MSM), female sex workers (FSW), people who inject drugs (PWID), and transgender persons, in 8 West and Central Africa countries: Cameroon, Chad, Cote d'Ivoire, Democratic Republic of Congo, Ghana, Guinea-Bissau, Niger, and Nigeria. METHODS A comprehensive search of peer-reviewed literature was conducted using PubMed and MEDLINE. This search was supplemented by an additional search of relevant non-peer-reviewed, or gray, literature. Available data on HIV prevalence, KP size estimates, HIV prevention service targets, and HIV prevention service coverage, including the availability of population-specific minimum packages of services, were included in the review. RESULTS No data for transgender persons were found. HIV prevalence data and size estimates were more frequently available for FSW, followed by MSM. Only 2 countries (Ghana and Nigeria) had both KP size estimates and HIV prevalence data for PWID. The degree to which HIV prevention service targets were adopted was highly variable across the selected countries, and the collection of relevant HIV prevention service coverage data for those targets that were identified was inconsistent. Population-specific minimum packages of services were identified in 3 countries (Cote d'Ivoire, Ghana, and Nigeria), although only Ghana and Nigeria included services for PWID. CONCLUSIONS Epidemiologic and HIV prevention service data for FSW, MSM, PWID, and transgender persons remain sparse, and these KP are inconsistently accounted for in-service delivery and nationally endorsed minimum packages of HIV services in West and Central Africa. The strengthening of data collection and reporting to consistently include KP and the inclusion of that data in national planning is imperative for effectively addressing the HIV epidemic.

Potential impact of existing interventions and of antiretroviral use in female sex workers on transmission of HIV in Burkina Faso: a modeling study.

Abstract
BACKGROUND The impact and cost-effectiveness of antiretroviral treatment (ART) as prevention is likely to vary depending on the local context. Burkina Faso has a concentrated mature HIV epidemic where female sex workers (FSW) are thought to have driven HIV transmission. METHODS A dynamic HIV transmission model was developed using data from the Yerelon FSW cohort in Bobo-Dioulasso and population surveys. Compared with current ART provision [status quo (SQ)], the model estimated the proportion of HIV infections averted or incremental life-years gained per additional person-year of ART over 20 years for ART targeting different subgroups or expanding eligibility to all HIV-infected individuals compared with SQ. RESULTS Modeling suggests that condom use within commercial sex has averted 40% of past HIV infections. Continuing SQ averts 35%-47% of new infections over 20 years compared with no ART. Expanding ART eligibility to all HIV-infected individuals and increasing recruitment (80% per year) could avert a further 65% of new infections, whereas targeting full-time FSW or all FSWs achieved less impact but was more efficient in terms of life-years gained per 100 person-years of ART. Local HIV elimination is possible with expanded ART provision to FSWs but requires condom use within commercial sex to be maintained at high levels. CONCLUSIONS Increasing FSW recruitment onto ART could be a highly efficient method for reducing HIV transmission in concentrated epidemic settings but should not be undertaken at the expense of existing interventions for FSWs. Specialized clinics providing multiple interventions for FSWs should be a fundamental component of prevention in concentrated epidemics.

Abstract
BACKGROUND HIV infection and unintended pregnancy are occupational risks of commercial female sex work (FSW). The burden of unintended pregnancy among FSW including maternal and infant outcomes in the context of HIV is largely unknown. METHODS FSW ≥18 years were recruited through respondent driven sampling into a cross-sectional study in Abidjan, Côte d'Ivoire. Participants completed a sociobehavioral questionnaire and HIV counseling and testing. Pregnancy history by HIV status and contraceptive use were described, and Poisson regression used to estimate correlates of termination of pregnancy (TOP). RESULTS From March to July 2014, 466 FSW were enrolled. Unintended pregnancy was common, and 64% of participants had ≥1 TOP. Half of FSW experiencing TOPs did so without a medical professional, resulting in frequent complications. Contraceptive use was lowest among younger FSW, and 37% of 20-24 year olds reported multiple TOPs. FSW with a TOP history reported 19% less consistent condom use with clients than women who never had a TOP (adjusted-prevalence ratio, 0.81; 95% confidence interval: 0.74 to 0.88), whereas use of reliable nonbarrier contraceptive methods was comparable between the groups. Although FSW were engaged in HIV testing and prevention services, only 59% of FSW had received HIV testing before childbirth during their last pregnancy, and 30% of HIV-infected FSW had lost ≥1 children. CONCLUSIONS Low contraceptive use and high burden of unintended pregnancy result in poor reproductive outcomes for FSW and avoidable mother-to-child HIV transmission risks. Integration of family planning and antenatal services into HIV prevention and care programs accessed by FSW could enhance reproductive outcomes and HIV prevention goals.

Abstract
OBJECTIVES We used an individual-based model to evaluate the effects of hypothetical prevention interventions on HIV incidence trajectories in a concentrated, mixed epidemic setting from 2011 to 2021, and using Cabo Verde as an example. METHODS Simulations were conducted to evaluate the extent to which early HIV treatment and optimization of care, HIV testing, condom distribution, and substance abuse treatment could eliminate new infections (i.e., reduce incidence to less than 10 cases per 10,000 person-years) among non-drug users, female sex workers (FSW), and people who use drugs (PWUD). RESULTS Scaling up all four interventions resulted in the largest decreases in HIV, with estimates ranging from 1.4 (95 % CI 1.36-1.44) per 10,000 person-years among non-drug users to 8.2 (95 % CI 7.8-8.6) per 10,000 person-years among PWUD in 2021. Intervention scenarios prioritizing FWS and PWUD also resulted in HIV incidence estimates at or below 10 per 10,000 person-years by 2021 for all population sub-groups. CONCLUSIONS Our results suggest that scaling up multiple interventions among entire population is necessary to achieve elimination. However, prioritizing key populations with this combination prevention strategy may also result in a substantial decrease in total incidence.

Abstract
PURPOSE OF REVIEW Globally, HIV infection remains a significant issue for key populations such as men who have sex with men (MSM) and female sex workers. A review of recent articles was conducted for west African countries to assess the burden of disease among female sex workers and MSM, access to services and identify barriers to implementation of services for key populations. RECENT FINDINGS In west Africa, key populations engage in high-risk practices for the acquisition of HIV and other sexually transmitted infections. Available HIV prevalence data fluctuate across and within countries for both MSM and female sex workers and may be five to ten times as high as that of the general population. HIV prevalence varied from 15.9% in The Gambia to 68% in Benin among female sex workers, whereas it ranged from 9.8% in The Gambia to 34.9% in Nigeria for MSM. Yet, important data gaps exist, including key populations size estimations in several countries as well as HIV prevalence, incidence and other biomarkers of HIV risk. Because of sociocultural, legal, political and economic challenges, exacerbated by a poor health system infrastructure, the HIV response is not strategically directed toward programs for key populations in countries with concentrated epidemics. Noteworthy is the low coverage of prevention care and treatment interventions offered to key populations. SUMMARY Sufficient planning and political will with legal and structural frameworks that reconcile public health and human rights are needed to prioritize HIV prevention, care and treatment programming for key populations programs in west Africa.

Abstract
Studies completed over the past 15 years have consistently demonstrated the importance of community-level determinants in potentiating or mitigating risks for the acquisition and transmission of HIV. Structural determinants are especially important in mediating HIV risk among key populations, including men who have sex with men, people who inject drugs, sex workers of all genders, and transgender women. The objective of this systematic review was to synthesize the evidence characterizing the community-level determinants that potentiate or mitigate HIV-related outcomes for key populations. The results of the review suggest that although health communication programs represent community-level strategies that have demonstrated the effectiveness in increasing the uptake of HIV testing and decreasing the experienced stigma among people living with HIV, there are limited studies focused on key populations in low- and middle-income settings. Moreover, interpretation from the 22 studies that met inclusion and exclusion criteria reinforce the importance of the continued measurement of community-level determinants of HIV risks and of the innovation in tools to effectively address these risks as components of the next generation of the HIV response. Consequently, the next generation of effective HIV prevention science research must improve our understanding of the multiple levels of HIV risk factors, while programming for key populations must address each of these risk levels. Failure to do so will cost lives, harm communities, and undermine the gains of the HIV response.

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.

Abstract
Sexually transmitted infections (STIs) in Vietnam have been increasing. Control of STIs among female sex workers (FSWs) is important in controlling the epidemic. Effective STI control requires that physicians are skilful in taking sexual history for FSW patients. Three hundred and seventy-one physicians responded to a survey conducted in three provinces in Vietnam. The respondents were asked whether they asked FSW patients about their sexual history and information asked during sexual history taking. The respondents were also asked about their barriers for taking sexual history. Over one-fourth (27%) respondents always, over half (54%) respondents sometimes and 19% respondents never obtained a sexual history from FSW patients. Multivariable analysis revealed that factors associated with always taking a sexual history were being doctor, training in STIs and working at provincial level facilities. Physician’s discomfort was found to be inversely associated with training on communication with patients, seeing 15 or fewer patients a week, working at provincial level facilities. Issues in sexual history taking among FSW patients in general practice in Vietnam were identified. These issues can help STI control for FSW patients and need due attention in order to improve STI management in Vietnam.

[PMID: 24321113 PMCID: PMC3852130 DOI: 10.7448/ias.16.4.18751] [Citation(s) in RCA: 88] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2013] [Revised: 08/26/2013] [Accepted: 09/25/2013] [Indexed: 11/12/2022] Open
Abstract
Introduction
The West and Central Africa (WCA) sub-region is the most populous region of sub-Saharan Africa (SSA), with an estimated population of 356 million living in 24 countries. The HIV epidemic in WCA appears to have distinct dynamics compared to the rest of SSA, being more concentrated among key populations such as female sex workers (FSWs), men who have sex with men (MSM), people who inject drugs (PWID) and clients of FSWs. To explore the epidemiology of HIV in the region, a systematic review of HIV literature among key populations in WCA was conducted since the onset of the HIV epidemic. Methods
We searched the databases PubMed, CINAHL and others for peer-reviewed articles regarding FSWs, MSM and PWID in 24 countries with no date restriction. Inclusion criteria were sensitive and focused on inclusion of any HIV prevalence data among key populations. HIV prevalence was pooled, and in each country key themes were extracted from the literature. Results
The search generated 885 titles, 214 abstracts and 122 full articles, of which 76 met inclusion and exclusion criteria providing HIV prevalence data. There were 60 articles characterizing the burden of disease among FSWs, eight for their clients, one for both, six for MSM and one for PWID. The pooled HIV prevalence among FSWs was 34.9% (n=14,388/41,270), among their clients was 7.3% (n=435/5986), among MSM was 17.7% (n=656/3714) and among PWID from one study in Nigeria was 3.8% (n=56/1459). Conclusions
The disproportionate burden of HIV among FSWs appears to be consistent from the beginning of the HIV epidemic in WCA. While there are less data for other key populations such as clients of FSWs and MSM, the prevalence of HIV is higher among these men compared to other men in the region. There have been sporadic reports among PWID, but limited research on the burden of HIV among these men and women. These data affirm that the HIV epidemic in WCA appears to be far more concentrated among key populations than the epidemics in Southern and Eastern Africa. Evidence-based HIV prevention, treatment and care programmes in WCA should focus on engaging populations with the greatest burden of disease in the continuum of HIV care.

[PMID: 23898942 PMCID: PMC3750331 DOI: 10.1186/1471-2458-13-698] [Citation(s) in RCA: 85] [Impact Index Per Article: 7.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2013] [Accepted: 07/29/2013] [Indexed: 01/30/2023] Open
Abstract
Background Although disproportionately affected by HIV, sex workers (SWs) remain neglected by efforts to expand access to antiretroviral treatment (ART). In Zimbabwe, despite the existence of well-attended services targeted to female SWs, fewer than half of women diagnosed with HIV took up referrals for assessment and ART initiation; just 14% attended more than one appointment. We conducted a qualitative study to explore the reasons for non-attendance and the high rate of attrition. Methods Three focus group discussions (FGD) were conducted in Harare with HIV-positive SWs referred from the ‘Sisters with a Voice’ programme to a public HIV clinic for ART eligibility screening and enrolment. Focus groups explored SWs’ experiences and perceptions of seeking care, with a focus on how managing HIV interacted with challenges specific to being a sex worker. FGD transcripts were analyzed by identifying emerging and recurring themes that were specifically related to interactions with health services and how these affected decision-making around HIV treatment uptake and retention in care. Results SWs emphasised supply-side barriers, such as being demeaned and humiliated by health workers, reflecting broader social stigma surrounding their work. Sex workers were particularly sensitive to being identified and belittled within the health care environment. Demand-side barriers also featured, including competing time commitments and costs of transport and some treatment, reflecting SWs’ marginalised socio-economic position. Conclusion Improving treatment access for SWs is critical for their own health, programme equity, and public health benefit. Programmes working to reduce SW attrition from HIV care need to proactively address the quality and environment of public services. Sensitising health workers through specialised training, refining referral systems from sex-worker friendly clinics into the national system, and providing opportunities for SW to collectively organise for improved treatment and rights might help alleviate the barriers to treatment initiation and attention currently faced by SW.

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
Consistent condom use can prevent HIV infection, yet levels of condom use are low in many settings. This paper examines determinants of inconsistent condom use among 905 women enrolled in a high-risk cohort in Kampala, Uganda, who reported sexual intercourse with paying clients in the last month. Among these, 40% participants reported using condoms inconsistently with paying clients in the past month. The most common reason for inconsistent condom use was client preference. Factors independently associated with inconsistent condom use included: sex work not being the sole source of income [adjusted odds ratio (aOR) = 1.54; 95% confidence interval (CI): 1.13-2.09], sexual debut before 14 years (aOR = 1.46; 95% CI: 1.09-1.96), daily consumption of alcohol (aOR = 1.90; 95% CI: 1.26-2.88) and being currently pregnant (aOR = 2.11; 95% CI: 1.25-3.57). Being currently married (aOR = 0.36; 95% CI: 0.18-0.73) and a higher number of sexual partners per month (p-trend = 0.001) were associated with a lower risk of inconsistent condom use. Targeted programmes should be developed to promote consistent condom use in high-risk women, alongside interventions to reduce alcohol use.
