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

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

Behavioural Risk for HIV, Hepatitis B, and Hepatitis C Infections among a Population of Drug Users and Injectors across Four Regions in Ghana.

Background: Blood borne infections such as HIV, Hepatitis B (HBV), and Hepatitis C (HCV) are of great importance to governments and their implementing partners, especially among people who use drugs (PWUD) and people who inject drugs (PWID). Prevalence and determinants of HIV, HBV, and HCV among PWUD and PWID in Ghana are not well established, the significance of this study. Method: This assessment was a cross-sectional study implemented via the respondent driven sampling approach. A team of community advisory boards that comprised former users, current users, and civil society organizations were constituted to help in the implementation of the study. The study was conducted in four regions in Ghana. The assessment was based on a representation of populations of PWID and PWUD from the four regions. Efforts were made by the team to ensure adequate representation of women where feasible. A quantitative questionnaire was developed and used to obtain information on the respondents' sociodemographics, sexual behavior, substance use, and biological characteristics. The prevalence of HIV, HBV, and HCV among PWID and PWUD was determined using blood samples. First response and oral quick test for confirmation of HIV positivity were carried out, while SD bioline was used to test for the presence of HBV and HBC. Data were analyzed using the Bayesian generalized linear model via the binomial family of distributions under the logit link function with weak Cauchy and Normal distribution as prior. Results: A total of 323 PWUD and PWID participants were interviewed across four regions of Ghana. The overall median age of the respondents was 36 (28, 43) years. The prevalence of HIV, HBV, and HCV infection in the study was 2.5%, 4.6%, and 5.9%, respectively. The prevalence of HIV, HBV, and HCV among drug users was 2.5% (95% CI: 0.7%-4.2%), 4.1% (95% CI: 1.8%-6.2%), and 6.7% (95% CI: 3.9%-9.4%), respectively. Most drug injectors and users started using and injecting drugs at ages less than 20 years and between 20 and 29 years, respectively. Drug users who identified themselves as part of the general population were 66% less likely to be tested HIV positive (POR = 0.34, CrI: 0.12-0.81) compared to sex workers. Part time employment respondents had fivefold odds (POR = 5.50, CrI: 1.20-16.16) of being HBV positive as against full-time employment. Conclusion: Most of the injectors and users started drugs at an early age. Drug users and injectors are at higher risk of these infections because of associated risky sexual behaviors and risky injection practices. Harm reduction programs to help addicts who are willing to quit the practice are recommended.

A short history of HIV prevention programs for female sex workers in Ghana: lessons learned over 3 decades.

BACKGROUND: Female sex workers (FSWs) in Ghana have a 10-fold greater risk for acquiring HIV than the general adult population, and they contribute a substantial proportion of the new HIV infections in the country. Although researchers have conducted behavioral and biological surveys, there has been no review of the contextual, programmatic, and epidemiological changes over time. METHODS: The authors conducted a historical review of HIV prevention programs in Ghana. We reviewed the use of different interventions for HIV prevention among FSWs and data from program monitoring and Integrated Biological and Behavioral Surveillance Surveys. In particular, we looked at changes in service access and coverage, the use of HIV testing and counseling services, and the changing prevalence of HIV and other sexually transmitted infections. RESULTS: HIV prevention interventions among FSWs increased greatly between 1987 and 2013. Only 72 FSWs were reached in a pilot program in 1987, whereas 40,508 FSWs were reached during a national program in 2013. Annual condom sales and the proportion of FSWs who used HIV testing and counseling services increased significantly, whereas the prevalence of gonorrhea and chlamydia decreased. The representation of FSWs in national HIV strategic plans and guidelines also improved. CONCLUSIONS: Ghana offers an important historical example of an evolving HIV prevention program that-despite periods of inactivity-grew in breadth and coverage over time. The prevention of HIV infections among sex workers has gained momentum in recent years through the efforts of the national government and its partners-a trend that is critically important to Ghana's future.

Periodical antibiotic treatment for the control of gonococcal and chlamydial infections among sex workers in Benin and Ghana: a cluster-randomized placebo-controlled trial.

BACKGROUND: In resource-poor settings, control of Neisseria gonorrhoeae (NG) and Chlamydia trachomatis (CT) among female sex workers (FSWs) is difficult. We sought to determine whether periodical antibiotic treatment (PAT) might be effective in controlling these infections among West African FSWs. Secondary objectives were to determine the impact of PAT on human immunodeficiency virus (HIV) incidence among FSWs and on NG/CT prevalence among their clients. METHODS: Cluster-randomized, double-blind, placebo-controlled trial among FSW communities in Benin and Ghana. Within each of 9 pairs of clusters of FSW communities, one was allocated to receive, during 9 months, a monthly antibiotic (alternatively ciprofloxacin or azithromycin, n = 296 FSWs) and the other a placebo (n = 340 FSWs). Prevalence of NG/CT infections was measured at 3-month intervals using the polymerase chain reaction. HIV status was determined at the beginning and at the end of the study. RESULTS: After adjusting for age, HIV status, duration of prostitution, price per intercourse and condom use, and accounting for prevalence at enrollment and cluster-pairing effect, prevalence ratios (intervention vs. placebo) of NG infection were 0.77 (P = NS), 1.07 (P = NS), and 0.49 (P = 0.05) at the first, second, and third follow-up visits, respectively. PAT neither reduced significantly CT prevalence or HIV incidence among FSWs nor NG/CT prevalence among their clients. CONCLUSION: The only beneficial impact of PAT was on the prevalence of gonococcal infections among FSWs 9 months after the beginning of the intervention. Although PAT could be more effective in other circumstances, for instance, in the early stages of a program for FSWs, it can not be recommended at present as a routine strategy to control cervical infections among FSWs.

The syndromic management of vaginal discharge using single-dose treatments: a randomized controlled trial in West Africa.

OBJECTIVE: To evaluate whether single-dose treatments are as effective as standard therapy in the syndromic management of vaginal discharge. METHODS: A randomized controlled effectiveness trial compared single-dose tinidazole plus fluconazole (TF) with treatment for 7 days with metronidazole plus 3 days of treatment with vaginal clotrimazole (MC) among 1570 women presenting with vaginal discharge at primary health care institutions in Ghana, Guinea, Mali and Togo. Participants were randomly allocated to one of the two treatments by research nurses or physicians using precoded envelopes. Effectiveness was assessed by symptomatic response on day 14. CLINICAL IDENTIFIER ClinicalTrials.gov NCT00313131. FINDINGS: The two treatment regimens had similar effectiveness: complete resolution was seen in 66% (TF) and 64% (MC) and partial resolution in 33% (TF) and 34% (MC) of participants (P = 0.26). Effectiveness was similar among subgroups with vulvovaginal candidiasis, Trichomonas vaginalis vaginitis or bacterial vaginosis. The two treatment regimens had a similar effectiveness among human immunodeficiency virus (HIV)-infected (TF: n = 76, 71% complete resolution, 28% partial; MC: n = 83, 72% complete resolution, 25% partial, P = 0.76) and HIV-uninfected women (TF: n = 517, 68% complete, 32% partial; MC: n = 466, 65% complete, 33% partial, P = 0.20). Cervical infections with Neisseria gonorrhoeae, Chlamydia trachomatis and Mycoplasma genitalium were uncommon among women not involved in sex work, were associated with bacterial vaginosis or T. vaginalis vaginitis, and did not alter response to treatment with agents active against vaginal infections. Four-fifths of women not relieved by a single dose of TF had a favourable response when MC was administered as second-line treatment. CONCLUSION: Single-dose TF is as effective as multiple-dose MC in the syndromic management of vaginal discharge, even among women with HIV-infection. Given its low price and easier adherence, TF should be considered as a first-line treatment for vaginal discharge syndrome.

Transactional sex is the driving force in the dynamics of HIV in Accra, Ghana.

OBJECTIVE: To delineate the population attributable fraction (PAF) of transactional sex in prevalent cases of HIV infection in the male adult population of Accra, Ghana. DESIGN AND METHODS: Cross-sectional study of clients who visited a sex worker (SW), of boyfriends of SW and of male personnel in prostitution venues. A questionnaire was administered and urine obtained for detection of anti-HIV antibodies. The PAF of prevalent HIV acquired from SW was calculated using a combination of data from this survey of clients, from on-going SW surveys, the national HIV surveillance system and the national census. RESULTS: HIV prevalence was 4.9% (8/162) among clients of mobile SW, 15.8% (53/335) among clients of home-based SW, 17.5% (10/57) among personnel and 32.1% (9/28) among boyfriends. A condom was used in 90% of intercourses, according to clients. Non-use of a condom was clustered in selected locations and independently associated with older age of client, frequency of intercourse with SW in the last year and current urethritis. Among the male population of Accra aged 15-59 years, 84% of prevalent cases of HIV were attributable to transactional sex. A sensitivity analysis showed that under various assumptions PAF varied between 47% and 100%. CONCLUSIONS: In Accra, approximately four-fifths of prevalent cases of HIV in adult males were acquired from SW. Comprehensive interventions providing education, condoms and treatment for sexually transmitted diseases for SW and their clients should be approached as other public health priorities and provided in all cities, large and small, of West Africa.
