Human Papillomavirus Types and Cervical Cancer Screening among Female Sex Workers in Cameroon.

Female sex workers (FSWs) are at high risk for sexually transmitted infections (STIs), including infection with human papillomavirus (HPV) and cervical cancer due to occupational exposure. The objective of this study was to estimate the prevalence of HPV, HPV types, and precancerous lesions of the cervix among FSWs in Cameroon. In this cross-sectional study, FSWs in Cameroon aged 30 years and above were screened for cervical cancer using high-risk HPV testing and genotyping and visual inspection with acetic acid and Lugol's iodine (VIA/VILI) enhanced using digital cervicography (DC) simultaneously. Those who were positive for VIA/VILI-DC were provided treatment with thermal ablation (TA) immediately for cryotherapy/TA-eligible lesions while lesions meeting the criteria for large loop excision of the transformation zone (LLETZ) were scheduled at an appropriate facility for the LLETZ procedure. HPV-positive FSWs without any visible lesion on VIA/VILI-DC were administered TA. Bivariate analyses were conducted to compare demographic and clinical characteristics. Crude and adjusted logistic regression models were computed for HPV infection status and treatment uptake as outcomes in separate models and their ORs and 95% confidence intervals (95% CI) were reported. Among the 599 FSWs aged 30 years and older that were screened for HPV and VIA/VILI-DC, 62.1% (95% CI: (0.58-0.66)) were positive for one or more HPV types. HPV type 51 had the highest prevalence (14%), followed by types 53 (12.4%) and 52 (12.2%). Type 18 had the lowest prevalence of 2.8% followed by type 16 with 5.2%. In the multivariable model, HIV-positive FSWs were 1.65 times more likely to be infected with HPV compared to their HIV-negative counterparts (AOR: 1.65, CI: 1.11-2.45). A total of 9.9% of the 599 FSWs were positive for VIA/VILI-DC. The prevalence of HPV infection among FSWs in Cameroon is higher than the worldwide pooled FSW prevalence. HPV types 51 and 53 were the most prevalent, while types 18 and 16 were the least prevalent. HIV status was the only variable that was significantly associated with infection with HPV.

HIV treatment cascade among female sex workers in Ethiopia: Assessment against the UNAIDS 90-90-90 targets

Background HIV treatment cascades for HIV-positive female sex workers (FSWs) have been challenged by the overlapping stigma and discrimination associated with both their sex work and HIV status. This study aims to assess the proportion of HIV-positive FSWs who access care and treatment in Ethiopia. Method A cross-sectional study with a respondent-driven sampling technique was used to enroll 6,085 female sex workers from January to June 2020. Interviews were conducted to assess the FSWs’ HIV status awareness and access to ART. A blood sample was drawn to determine the current HIV status and viral load level. Logistic regression was run to identify factors associated with FSWs’ HIV status awareness. Results Of the total 1140 HIV-positive FSWs, 50.38% knew they were HIV positive; 92.88% of those who knew their status were on ART, and 91.68% of those on ART had attained viral suppression of less than 1000 copies per milliliter. The adjusted odds of knowing HIV status was 3.20 (95% CI; 2.00, 5.13) among those aged 35 years and older, 1.81 (95% CI; 1.05, 3.12) among widowed, and 1.73 (95% CI; 1.28, 2.32) in those who did not perceive the risk of HIV acquisition. Conclusion Only about half of HIV-positive FSWs knew they were HIV positive. More than 90% of those who knew their status were put on ART and achieved viral suppression. The weakest point in achieving HIV control among FSWs is the identification of those living with HIV.

The effect of drop-in centers on access to HIV testing, case finding, and condom use among female sex workers in Addis Ababa, Ethiopia.

Varied HIV prevention interventions involving multiple strategies has been instrumental in the effort to contain and lessen the prevalence of HIV around the globe. However, female sex workers (FSWs) often face stigma and discriminatory challenges, resulting in lower access to the HIV prevention initiatives. This study has aimed to assess the effect of one of the HIV service delivery models, the Drop-in Centers (DICs), which is designed to overcome the service uptake barriers of FSWs. A quasi-experimental study design was employed. A respondent-driven sampling technique was used to recruit 1,366 FSWs from January to June 2020. A propensity score matching technique was used to balance the potential confounders between FSWs who had access to DICs and those who had never accessed DICs. Comparisons of the effect of DIC on the outcome of interest was made using a logit regression model at a 5% level of significance. A total of 1,366 FSWs took part in the study. The analysis estimated the average treatment effects of access to DICs on four key outcomes: ever-testing to know HIV status, finding HIV-positive FSWs, awareness of HIV-positive status, and consistent condom use. A significant effect of DIC was seen at a 95% confidence interval on each outcome. Access to DIC produced a 7.58% increase in the probability of testing to know HIV status (P < 0.001), a 7.02% increment in finding HIV-positive FSWs (P = 0.003), an increase of 6.93% in awareness of HIV status among HIV positive FSWs (P = 0.001), and a 4.39% rise in consistent condom use (P = 0.01). Ensuring access of FSWs to DICs has led to an upsurge in HIV testing among FSWs, raising HIV status awareness among those who are HIV positive, and encouraged consistent condom use. To provide effective HIV prevention services, particularly to those FSWs living with HIV, it is essential to strengthen the services provided in DICs and expand the centers. This will ensure that the entire network of FSWs is reached with appropriate HIV prevention services.

Molecular epidemiology of HIV-1 among adult female sex workers at the Guatemala-Mexico border

ABSTRACT Sex workers have been demonstrated to have increased vulnerabilities to HIV and a high population prevalence of the disease. Despite their increased risk, sex workers have been underrepresented in molecular epidemiology studies assessing HIV in Mesoamerica. This study aims to describe the sociodemographic characteristics and phylogenetic profile of HIV-1 within a cohort of HIV-positive female sex workers (FSW) situated at the Guatemala-Mexico border. HIV viral sequences were collected from a cohort of FSW ≥18 years of age from San Marcos, Guatemala (n = 6) and compared to viral sequences collected as part of the Mesoamerican Drug Resistance Monitoring Programme to assess HIV viral diversity in Mexico and Guatemala (n = 3956). All of the FSW sampled were determined to have genetically unrelated HIV infections, suggesting multiple introductions of the virus and/or the potential existence of populations not captured by current surveillance efforts. Many reported numerous vulnerabilities that may have heightened their risk of acquiring and transmitting HIV through sex work activities. Our phylogenetic analysis indicated that national surveillance programmes may not fully capture the viral diversity among FSW and their clients within this region. Additional research is needed to fully capture HIV diversity and transmission in Mesoamerica, especially in the Guatemala-Mexico border region.

The prevalence of Chlamydia trachomatis infection by Nucleic Acid Amplification test in women of reproductive age group under treatment for infertility

BackgroundIn India, the prevalence of Chlamydia Trachomatis (CT) studies in different groups are focused on high-risk populations – HIV-positive women and female sex workers – and have shown a variable prevalence rate ranging from 1.1 to 45%. One concern about comparing these studies is that the enzyme-linked immunosorbent assay (ELISA) test is estimated to be only 65–70% sensitive. The data of CT prevalence among women undergoing treatment for infertility, using more sensitive methods, such as Nucleic Acid Amplification Test (NAAT), are sparse. The disease is easily treatable, and knowledge of prevalence will provide the burden of disease on fertility. MethodsA cross-sectional hospital-based observational study was carried out on 169 patients attending an infertility clinic at assisted reproductive technology (ART) center or gynecology outpatient department (OPD) of a tertiary care hospital. ResultsThe overall prevalence was 8.87% with the highest prevalence (53.84%) among the women having vaginal discharge. The prevalence in patients with secondary infertility (10.81%) was higher than in those with primary infertility (7.36%). ConclusionIt is recommended that patients attending gynecological OPD in low resource setting to be treated for Chlamydia empirically and if facilities permit then they should undergo NAAT for CT detection. Screening programs are warranted among Indian women of child bearing age to prevent complications of Chlamydia infection like tubal blockage and dyspareunia.

HIV prevalence and associated factors among female sex workers in Iran: a bio-behavioral survey in 2020.

Despite the overall decline in human immunodeficiency virus (HIV) prevalence, it remains unacceptably high in key populations. This study aimed to estimate prevalence of HIV infection and high-risk behaviors among female sex workers (FSWs). This study was a cross-sectional survey of FSWs conducted between December 2019 and August 2020 in eight geographically diverse cities in Iran. After providing informed consent, participants completed a bio-behavioral questionnaire and after completion of the interview, rapid diagnostic tests (RDT) and dried blood spots (DBS) were collected to determine HIV and syphilis status as per national guidelines, if the women consented. All analyzes were based on RDS adjustment. Weighting was done according to Giles’SS estimator. Among the 1515 FSWs, the overall prevalence of HIV and syphilis were 1.6% (95% CI: 0.8–2.3) and zero, respectively. The highest HIV prevalence was observed in Shiraz (5.1%) and Khorramabad city (1.6%). In addition, HIV-positive FSWs had a higher mean age at first sexual contact than HIV-negative FSWs (21.4 ± 5.6 vs. 17.2 ± 4.2 years). Injection drug use and a history of arrest or incarceration were associated with an increased odds of HIV infection (OR = 6.25; 95% CI: 1.90-20.55 and OR = 4.57; 95% CI: 1.64–12.72, respectively). Based on the results, strategies to improve early HIV diagnosis, harm reduction, and use of testing and treatment strategies are needed to reduce and control HIV infections.

Engagement in HIV services over time among young women who sell sex in Zimbabwe.

Young female sex workers (FSW) are disproportionately vulnerable to HIV. Zimbabwe data show higher HIV incidence and lower engagement in services compared to older FSW. Utilizing data from a combination HIV prevention and treatment intervention, we describe engagement in the HIV services over time among FSW 18-24 years, compared to those ≥25 years of age. Data were collected via respondent-driven sampling (RDS) surveys in 14 communities in 2013 and 2016, with >2500 FSW per survey. They included blood samples for HIV and viral load testing. As the intervention had no significant impact on HIV care cascade outcomes, data were aggregated across study arms. Analyses used RDS-II estimation. Mean age in 2013 and 2016 was 31 and 33 years, with 27% and 17% aged 18-24 years. Overall HIV prevalence was 59% at each timepoint, and 35% and 36% among younger FSW. From 2013 to 2016 there was an increase in young HIV-positive FSW knowing their status (38% vs 60%, OR = 2.51, p<0.01). Outcomes for all FSW improved significantly over time at all steps of the cascade, and the relative change over time was similar among older versus younger FSW for most cascade variables. Young FSW had improvements in care cascade outcomes, and proportionate improvements similar to older FSW, yet they remain less engaged in services overall. This implies that the dedicated FSW services in Zimbabwe are having a comparably positive impact across age groups, however more is likely required to address young FSW's unique vulnerabilities and needs.

Predictive Factors of HIV-1 Drug Resistance and Its Distribution among Female Sex Workers in the Democratic Republic of the Congo (DRC).

The predictive factors of HIV-1 drug resistance and its distribution are poorly documented in female sex workers (FSWs) in the Democratic Republic of the Congo (DRC). However, the identification of predictive factors can lead to the development of improved and effective antiretroviral therapy (ART). The objective of the current study was to determine the predictive factors of HIV-1 drug resistance and its distribution based on FSWs in the studied regions in the Democratic Republic of the Congo (DRC). HIV-positive FSWs who were diagnosed as part of the DRC Integrated Biological and Behavioral Surveillance Survey (IBBS) were included in this study. A total of 325 FSWs participated. The HIV-1 viral load (VL) was measured according to the Abbott m2000sp and m2000rt protocols. The homogeneity chi-square test was conducted to determine the homogeneity of HIV-1 drug resistance distribution. Using a significance level of 0.05, multivariate analyses were performed to identify factors associated with HIV-1 drug resistance to ART. HIV drug resistance mutation (HIVDRM) distribution was homogeneous in the three study regions (p = 0.554) but differed based on the HIV-1 VLs of the FSWs. FSWs with high HIV-1 VLs harbored more HIVDRMs (p = 0.028) of predominantly pure HIV-1 strains compared with those that had low HIV-1 VLs. Sexually transmitted infection (STI) history (aOR [95%CI] = 8.51 [1.62, 44.74]), high HIV-1 VLs (aOR [95%CI] = 5.39 [1.09, 26.74]), and HIV-1–syphilis coinfection (aOR [95%CI] = 9.71 [1.84, 51.27]) were associated with HIV drug resistance among FSWs in the DRC. A history of STIs (e.g., abnormal fluid) in the 12 months prior to the survey, a high HIV-1 VL, and HIV-1–syphilis coinfection were associated with HIV-1 drug resistance among FSWs in the DRC. Efforts should be made to systematically test for other infections which increase the HIV-1 VL, in the case of HIV-1 coinfection, in order to maintain ART effectiveness across the DRC.

\u201cMy condition is my secret\u201d: perspectives of HIV positive female sex workers on differentiated service delivery models in Kampala Uganda

BackgroundDifferentiated service delivery (DSD) models for female sex workers (FSWs) continue to be scaled up with the goal of expanding access to HIV services and treatment continuity. However, little is known about FSWs’ perspectives on their preferences, facilitators, and barriers to the effective utilization of various DSD models.MethodsWe conducted 24 in-depth interviews among FSWs on antiretroviral therapy for at least one year in two drop-in centres and two public health facilities in Kampala, Uganda in January 2021.ResultsThe facility-based individual management model was most preferred, due to a wide array of comprehensive health services, privacy, and professional health workers. Community DSD models were physically accessible, but least preferred due to stigmatization and discrimination, lack of privacy and confidentiality, and limited health services offered.ConclusionTargeted strategies to reduce stigma and discrimination and the provision of high-quality services have potential to optimise FSWs’ access to HIV services.

Progress toward the UNAIDS 90\u201390-90 targets among female sex workers and sexually exploited female adolescents in Juba and Nimule, South Sudan

BackgroundLittle is known about HIV in South Sudan and even less about HIV among female sex workers (FSW). We characterized progress towards UNAIDS 90–90-90 targets among female sex workers (FSW) and sexually exploited female adolescents in Juba and Nimule, South Sudan.MethodsWe conducted a biobehavioral survey of FSW and sexually exploited female adolescents using respondent-driven sampling (RDS) in Juba (November 2015–March 2016) and in Nimule (January–March 2017) to estimate achievements toward the UNAIDS 90–90-90 targets (90% of HIV-positive individuals know their status; of these, 90% are receiving antiretroviral therapy [ART]; and of these, 90% are virally suppressed). Eligibility criteria were girls and women who were aged ≥15 years; spoke English, Juba Arabic, or Kiswahili; received money, goods, or services in exchange for sex in the past 6 months; and resided, worked, or socialized in the survey city for ≥1 month. Data were weighted for RDS methods.ResultsWe sampled 838 FSW and sexually exploited female adolescents in Juba (HIV-positive, 333) and 409 in Nimule (HIV-positive, 108). Among HIV-positive FSW and sexually exploited female adolescents living in Juba, 74.8% self-reported being aware of their HIV status; of these, 73.3% self-reported being on ART; and of these, 62.2% were virally suppressed. In Nimule, 79.5% of FSW and sexually exploited female adolescents living with HIV self-reported being aware of their HIV status; of these, 62.9% self-reported being on ART; and of these, 75.7% were virally suppressed.ConclusionsAlthough awareness of HIV status is the lowest of the 90–90-90 indicators in many countries, treatment uptake and viral suppression were lowest among FSW and sexually exploited female adolescents in South Sudan. Differentiated service delivery facilitate linkage to and retention on treatment in support of attainment of viral suppression.

A Prospective Study of Depressive Symptoms, Condomless Sex, and HIV Viral Load in HIV-Positive Female Sex Workers in Kenya.

The relationships between depressive symptoms, viral suppression, and condomless sex were examined in a prospective cohort study of 369 HIV-positive Kenyan female sex workers. Participants were screened for depressive symptoms at baseline and every six months until completion of the study (up to 66months). HIV viral load (VL) was measured every six months and prostate specific antigen (PSA) testing in vaginal secretions was performed quarterly. Mild or greater depressive symptoms were found in 100 (27.1%) women and were associated with increased risk of detectable VL (aRR 1.41, 95%CI 0.97-2.07, p-value = 0.07), but were not associated with detectable PSA. The co-occurrence of PSA detection and detectable VL at the same visit suggests the potential for HIV transmission but was uncommon (2.4% of visits). The prevalence of depressive symptoms and the association with detectable VL suggests the need for screening and treatment of depression for comprehensive HIV care in this population.

Alcohol use and viral suppression in HIV-positive Kenyan female sex workers on antiretroviral therapy

BackgroundExcessive alcohol intake has been associated with poor adherence to antiretroviral therapy (ART). The impact of alcohol on viral suppression is particularly important among groups at high risk of HIV transmission, such as female sex workers (FSWs). Few studies have directly evaluated the association between alcohol use and HIV viral load. We hypothesized that hazardous or harmful alcohol use is associated with detectable plasma viral load among HIV-positive FSWs.MethodsA prospective cohort study was conducted among HIV-positive FSWs in Mombasa, Kenya. Hazardous or harmful alcohol use was assessed yearly and defined as an Alcohol Use Disorders Identification Test (AUDIT) score ≥7. Detectable viral load was assessed every six months and defined as ≥180 c/mL. Adherence measures were collected monthly and included late ART refill (>48 hours) and self-reported adherence, using both a validated self-rating scale of ability to take medication and visual analog scale (VAS) of ART use in the last month. Generalized estimating equations were used to estimate adjusted relative risks (aRR) and 95% confidence intervals (CI).ResultsThis analysis included 366 participants followed monthly between October 2012 and March 2018. At baseline, AUDIT scores indicated hazardous alcohol use (AUDIT 7–15) in 14.3%, harmful alcohol use (AUDIT 16–19) in 1.4%, and alcohol dependency (AUDIT ≥20) in 1.4% of participants. After adjusting for potential confounders, a combined exposure including hazardous, harmful, and dependent alcohol use was not associated with detectable viral load (aRR 1.10, 95%CI 0.63–1.92) or late ART refill (aRR 1.13, 95%CI 0.82–1.56), but was associated with lower self-rated ability to take medication (aRR 2.38, 95%CI 1.42–3.99) and a lower rate of self-reported perfect ART adherence by VAS (aRR 2.62, 95%CI 1.84–3.71).ConclusionsIn this FSW cohort, while participants reporting hazardous, harmful, or dependent alcohol use were not more likely to have a detectable viral load, they were more likely to report lower ART adherence. These results suggest that interventions targeting alcohol use among this population of FSWs may not have a large impact on viral suppression.

Antiretroviral drug use and HIV drug resistance in female sex workers in Tanzania and the Dominican Republic.

ObjectiveFemale sex workers (FSW) have increased risk of HIV infection. Antiretroviral treatment (ART) can improve HIV outcomes and prevent HIV transmission. We analyzed antiretroviral (ARV) drug use and HIV drug resistance among HIV-positive FSW in the Dominican Republic and Tanzania.MethodsPlasma samples collected at study entry with viral loads >1,000 copies/mL were tested for ARV drugs and HIV drug resistance. ARV drug testing was performed using a qualitative assay that detects 22 ARV drugs in five classes. HIV genotyping was performed using the ViroSeq HIV-1 Genotyping System. Phylogenetic analyses were performed to determine HIV subtype and assess transmission clusters.ResultsAmong 410 FSW, 144 (35.1%) had viral loads >1,000 copies/mL (DR: n = 50; Tanzania: n = 94). ARV drugs were detected in 36 (25.0%) of 144 samples. HIV genotyping results were obtained for 138 (95.8%) cases. No transmission clusters were observed in either country. HIV drug resistance was detected in 54 (39.1%) of 138 samples (31/35 [88.6%] with drugs detected; 23/103 [22.3%] without drugs detected); 29/138 (21.0%) had multi-class resistance (MCR). None with MCR had integrase strand transfer inhibitor resistance. In eight cases, one or more ARV drug was detected without corresponding resistance mutations; those women were at risk of acquiring additional drug resistance. Using multivariate logistic regression, resistance was associated with ARV drug detection (p<0.001), self-reported ART (full adherence [p = 0.034]; partial adherence [p<0.001]), and duration of HIV infection (p = 0.013).ConclusionsIn this cohort, many women were on ART, but were not virally suppressed. High levels of HIV drug resistance, including MCR, were observed. Resistance was associated with detection of ARV drugs, self-report of ART with full or partial adherence, and duration of HIV infection. These findings highlight the need for better HIV care among FSW to improve their health, reduce HIV drug resistance, and decrease risk of transmission to others.

Brief Report: Incidence and Correlates of Pregnancy in HIV-Positive Kenyan Sex Workers.

The incidence of pregnancy in female sex workers (FSWs) living with HIV is not well characterized. Current and former FSWs living with HIV and enrolled in a prospective cohort study in Mombasa, Kenya, were followed monthly to ascertain sexual behavior and underwent quarterly pregnancy testing. Pregnancies were considered planned, mistimed, or unwanted according to fertility desires and pregnancy intentions. Cox proportional hazards models were used to estimate hazard ratios (HRs) of the association between characteristics and incident pregnancy. Two hundred seventy-nine FSWs were eligible (October 2012-April 2017). Most women had a nonpaying, regular partner (83.2%, 232/279), were not using modern nonbarrier contraception (69.5%, 194/279), and did not desire additional children (70.6%, 197/279). Of 34 first incident pregnancies [5.8/100 person-years (p-y); 95% confidence interval (CI): 4.1 to 8.0], 91.2% (n = 31) were unintended. The incidences of planned (5.7/100 p-y, n = 3), mistimed (10.4/100 p-y, n = 9), and unwanted pregnancies (4.9/100 p-y, n = 22) were similar (P = 0.15). In univariable analysis, oral contraceptive pill use (versus no contraception), having a nonpaying, regular partner, transactional sex, vaginal washing, condomless sex, and higher sex frequency were associated with an increased pregnancy risk. Older age was associated with a lower pregnancy risk. In multivariable analysis, having a nonpaying, regular partner (adjusted HR 4.0, 95% CI: 1.2 to 14.1) and age ≥40 years (aHR 0.2, 95% CI: 0.0 to 0.9) remained significantly associated with a higher and lower pregnancy risk, respectively. In this cohort of HIV-positive FSWs, most pregnancies were unintended. Identifying FSWs' fertility desires and pregnancy intentions could facilitate efforts to increase contraceptive use and implement safer conception strategies.

Safer conception for female sex workers living with HIV in Dar es Salaam, Tanzania: Cross-sectional analysis of needs and opportunities in integrated family planning/HIV services.

BackgroundWith the advent of effective treatment, women living with HIV can plan for pregnancy while minimizing risk of transmission to infants and seronegative partners. Family planning (FP) services tend to focus solely on addressing contraceptive need, but HIV-positive women—including female sex workers—often plan to have children someday. Various “safer conception” strategies are now available to support women living with HIV achieve fertility intentions, and integrated HIV/FP services may be a promising platform to offer these services.MethodsAt integrated community-based HIV/FP service delivery sites operated by Jhpiego’s Sauti project in Dar es Salaam, we conducted exit interviews with 300 HIV-positive female sex workers. Descriptive analyses were conducted to describe their desire for children, use of condoms and other modern contraceptive methods, self-reported viral suppression, and knowledge of and interest in safer conception strategies. We conducted bivariate and multivariate logistic regression analysis to examine correlates of fertility desire among respondents.ResultsMedian age of participants was 32. Nearly one-third wished to have a child within two years. Seventy-two percent had heard of having the HIV-positive partner taking ART to reduce sexual transmission during pregnancy attempts. Thirty-one percent felt the amount of FP content covered in the consultation was “too little.” Factors significantly associated with desire for children were having a nonpaying partner (adjusted odds ratio [AOR] 2.18, 95% confidence interval [CI]1.13–4.20) and having fewer children (AOR 0.65, 95% CI 0.48–0.87). Viral suppression was not associated with fertility desire.ConclusionsSex workers living with HIV attending integrated HIV/FP services have need for both contraception as well as safer conception counseling. This integrated service delivery modality is a promising platform for providing safer conception services. FP counseling for HIV-positive women should be broadened to broach the topic of safer pregnancy, as well as explicit counseling on strategies to minimize risk of sexual transmission to partners.

HIV Prevalence, Risk Factors for Infection, and Uptake of Prevention, Testing, and Treatment among Female Sex Workers in Namibia

BackgroundIn most settings, Female Sex Workers (FSW) bear a disproportionate burden of Human Immunodeficiency Virus (HIV) disease worldwide. Representative data to inform the development of behavioral and biomedical interventions for FSW in Namibia have not been published.ObjectivesOur objectives were to measure HIV prevalence, identify risk factors for infection, and describe uptake of prevention, testing, and treatment among FSW in Namibia.MethodsWe conducted cross-sectional surveys using Respondent-driven Sampling (RDS) in the Namibian cities of Katima Mulilo, Oshikango, Swakopmund/Walvis Bay, and Windhoek. Participating FSW completed behavioral questionnaires and rapid HIV testing.ResultsCity-specific ranges of key indicators were: HIV prevalence (31.0–52.3%), reached by prevention programs in the past 12 months (46.9–73.6%), condom use at last sex with commercial (82.1–91.1%) and non-commercial (87.0–94.2%) partners, and tested for HIV within past 12 months or already aware of HIV-positive serostatus (56.9–82.1%). Factors associated with HIV infection varied by site and included: older age, having multiple commercial or non-commercial sex partners, unemployment, being currently out of school, and lower education level. Among HIV-positive FSW, 57.1% were aware of their HIV-positive serostatus and 33.7% were on antiretroviral treatment.DiscussionOur results indicate extremely high HIV prevalence and low levels of case identification and treatment among FSW in Namibia. Our results, which are the first representative community-based estimates among FSW in Namibia, can inform the scale-up of interventions to reduce the risk for HIV acquisition and onward transmission, including treatment as prevention and pre-exposure prophylaxis.

The occurrence of cryptosporidiosis and amoebiasis among HIV infected female sex workers with symptomatic diarrhoea

Objectives: Manipur is one of the high HIV prevalence states of India.Quite a good number of HIV infected females are indulged in the profession of sex workers. These female sex workers (FSWs) are experiencing a number of gastrointestinal related disorders including diarrhoea caused by a wide variety of pathogens, including parasites. Therefore, the present study is being undertaken with a view assessing the occurrence of enteric parasites, especially Cryptosporidium sp and Entamoeba histolytica towards their involvement as the diarrhoeagenic agent(s) in these groups of patients. Materials and Methods: A cross-sectional study was conducted in the Department of Microbiology, Regional Institute of Medical Sciences (RIMS) Hospital, Imphal, Manipurfrom1stJanuary to 31stDecember 2018.The study group included54 HIVseropositive female sex workers with symptomatic diarrhoea. Stool sample(s) preserved in 2.5% K2Cr2O7for Cryptosporidium sp and 10% buffer formalin for Entamoeba histolytica and other classical parasites were collected for this study. Results: The present study reveals that out of the selected 54 HIV positive FSWs screened for the presence of enteric parasitosis, 16 (29.62%) individuals were found positive for three parasitic infections– cryptosporidiosis, amoebiasis and hookworm infection. Both mixed infection (31.25%) and single infection (68.75%) were observed among the patients. Single infection with Cryptosporidium sp and Entamoeba histolytica were observed in 5 (31.25%) and 6 (37.5%) patients respectively. Patients in the age group of 25 -30 and 30-35 years were observed to have been more infected. Conclusion: The study reveals that intestinal parasitic infection caused by Cryptosporidium sp and Entamoeba histolytica are prevalent among the present study group of HIV infected female sex workers.

HIV infection risk and condom use among sex workers in Senegal: evidence from the list experiment method.

Social desirability bias, which is the tendency to under-report socially undesirable health behaviours, significantly distorts information on sensitive behaviours that is gained from self-reports. As a result, self-reported condom use among high-risk populations is thought to be systematically over-reported, and it is impossible to identify the determinants of condom use. The main objective of the article is to elicit unbiased information on condom use among female sex workers (FSWs) using the double list experiment method to analyse the role of HIV infection and exposure to HIV prevention methods in condom use. More specifically, the difference in levels of condom use between HIV-positive and HIV-negative FSWs is estimated. In addition, the role of FSWs' registration and participation in a pre-exposure prophylaxis (PrEP) demonstration project in condom use is considered. A list experiment was designed to elicit condom use information from 786 FSWs in Senegal who were surveyed in 2015 and 2017. Using the list experiment method, participants were randomly assigned to one of two groups (treatment or control) and were asked to report the number of statements they agreed with. Respondents assigned to the control group were presented with three non-sensitive items, whereas those allocated to the treatment group were presented with the same three statements plus the sensitive item (e.g. 'I used a condom during my last intercourse with a client'). Comparing the average number of sentences that were agreed with in both groups provides an estimation of the condom use rate in the treatment group and estimating such prevalence for several sub-groups allows the role of HIV infection risk in condom use to be identified. The percentage of FSWs using condoms in their last sexual intercourse with a client was 80% in 2015 and 78% in 2017, which was significantly lower than the 97% obtained in the face-to-face surveys in both waves. When estimating condom use among sub-groups with the list experiment method, we found that condom use among HIV-positive FSWs was only 34%, which was 47 percentage points lower than condom use among HIV-negative FSWs. We also found that registered FSWs are more likely to use condoms than clandestine FSWs. However, we did not find any difference in condom use between FSWs who were enrolled in the PrEP demonstration project and those who were not enrolled. Health policies should therefore aim to increase condom use among HIV-positive FSWs.

Antiretroviral treatment sharing among highly mobile Ugandan fisherfolk living with HIV: a qualitative study

ABSTRACT Antiretroviral treatment (ART) diversion from prescribed to non-prescribed users (i.e., sharing or selling) is an understudied dimension of HIV treatment adherence. We sought to explore ART diversion patterns in high-prevalence fishing communities on Lake Victoria, Uganda. We implemented a qualitative study in two fishing communities on Lake Victoria in south-central Uganda to identify facilitators of and pathways to ART diversion. We conducted 25 semi-structured interviews with HIV-positive fishermen (n = 25) and female sex workers (n = 10) covering personal and community experiences with ART selling/sharing, reasons for medication diversion, and potential solutions to reduce diversion. Data were analyzed using an adapted framework analysis approach. Participants reported frequent ART sharing within occupational networks, but no selling. Mobility was the principal driver of ART sharing and was associated with other barriers to treatment access including stigma, fear of negative health provider interactions, and transportation. ART sharing appears to emerge in response to short-term treatment interruptions in this setting. Future studies should explore characteristics and drivers of ART diversion in other high-burden settings and identify how these practices are correlated with key health outcomes like virologic failure and drug resistance.

Engagement in Antiretroviral Treatment and Modern Contraceptive Methods Among Female Sex Workers Living With HIV in Lesotho

Female sex workers (FSW) are disproportionately affected by HIV in Lesotho, which highlights the importance of contraception and antiretroviral therapy (ART) given occupational risks of unwanted pregnancies. Seven hundred and forty-four FSW recruited through respondent-driven sampling in Maputsoe and Maseru in Lesotho completed a questionnaire and HIV testing in 2014. RDS-adjusted HIV prevalence was high (66.1; 95% CI: 58.7–72.8); 56% of HIV + participants were not using non-barrier contraception, and 32% were on ART. Among HIV-positive FSW not using non-barrier contraception, negative correlates of ART engagement were older age, lower HIV education, and consuming 5+ alcoholic drinks/day. Tailored HIV information delivery efforts for FSW in Lesotho’s high HIV burden environment may reduce horizontal and vertical transmission risks.
