Generation Surveillance

Once recognized as the most severe in Europe, the HIV epidemic in Ukraine is concentrated among people who inject drugs, men who have sex with men, and female sex workers. Integrated biobehavioral surveys, as a part of the second generation surveillance, are used to monitor HIV infection trends in key populations since 2002. The present paper is focused on the analysis of HIV prevalence trends in four nationally representative rounds of integrated biobehavioral surveys from 2008/9, 2011, 2013, and 2015 in people who inject drugs, men who have sex with men, and female sex workers. Between 2008/9 and 2015, the HIV prevalence has decreased significantly in people who inject drugs (24.2 to 22.0%) and female sex workers (13.6 to 6.3%), while the change in men who have sex with men was not significant (8.5 to 7.8%). There was a significant increase in people who inject drugs and men who have sex with men between 2013 and 2015. In subgroups younger than 25 years, prevalence increased more than twofold in men who have sex with men (1.9 to 4.3%), with no changes in people who inject drugs and female sex workers. The observed decline in prevalence, especially in young subgroups, may result from the effect of extensive prevention efforts on drug injection-related transmission. Recent increase in young men who have sex with men may be a sign of a new wave of the epidemic in this group.

Capture Recapture

Background Key Population size estimation (PSE) is instrumental for HIV/STI preventive, treatment and care services planning, implementation and delivery. The objective was to estimate the overall population of female sex workers (FSW) in all the 16 regions of Ghana using different PSE methods. Method Mapping of venues and complete enumeration of seaters was conducted at the formative stage prior to the bio-behavioral survey (BBS). Three PSE methods were used to derive the size estimates of FSW in the 16 regions. These include: Capture-recapture (CRC), service multiplier and three-source capture recapture (3SCRC) methods. The final choice of the estimation method used to estimate the roamer population was 3SCRC. This method was chosen because of its perfect record-linkage–hierarchic combination of three names that minimizes overmatching as well as the addition of an interaction term in the model which corrects for the dependencies in CRC. Results The total population size estimate of the female sex workers in the country obtained for roamers using capture re-capture was 41,746 (95% CI: 41,488–41,932). Using the service multiplier, the total population for both the roamers and seaters was 41,153 (95% CI: 37,242–45,984). The 3-source capture re-capture yielded 55,686 roamers FSW (95% CI: 47,686–63,686). The seater population was 4,363 FSW based on census/complete enumeration. The total population size estimate of FSW (seaters and roamers) in Ghana was 60,049 when 3SCRC and census were added. This represents about 0.76% of all estimated adult females aged 15-49yrs in Ghana. Conclusion We report population size estimates (PSE) for FSW in Ghana. These estimates are the results of 3SCRC. These findings provide a valid and reliable source of information that should be referenced by government officials and policymakers to plan, implement and provide HIV/STI preventive, treatment, and care services for FSW in Ghana.

Abstract Background Drug use is a growing concern in Ghana. People who inject drugs (PWID) are highly vulnerable to HIV and other infectious diseases. Ghana’s National Strategic Plan for HIV/AIDS 2016–2020 identifies PWID as a key population, but efforts to address the needs of PWID have lagged behind those targeting sex workers and men who have sex with men. Lack of information about PWID is a critical barrier to implementing effective HIV prevention and treatment. We aimed to learn more about the vulnerability of the PWID population in order to inform much-needed harm reduction interventions. Methods From April to July 2018, we conducted a mixed methods study in Kumasi, Ghana, to identify all major drug using locations, count the numbers of PWID to obtain rough population size estimations, and administer anonymous surveys to 221 PWID regarding drug use and sexual behavior. We also tested for HIV, HCV, and HBV from syringes used by survey participants. Results Key informants identified five major drug using locations and estimated the total PWID population size to be between 600 and 2000. Enumerators counted between 35 and 61 individuals present at each of the five bases. Sharing syringes and reusing discarded syringes are common practices. Over half of survey participants (59%) reported past-month syringe sharing (34% used a used syringe and 52% gave away a used syringe). Individuals with higher injection frequency (≥ 21 times weekly) and who injected with four or more people had higher odds of syringe sharing. Of the survey participants reporting sex in the last month (23%), most reported having one partner, but only 12% used condoms. Nearly all women (11/13) reported exchanging sex for drugs and 6/13 reported exchanging sex for money in the last six months. Fifteen percent of participants (all men) reported paying for sex using drugs or money. Of the used syringes, prevalence estimates were 3% (HIV), 2% (HCV), and 9% (HBV). Conclusions Our findings confirm the urgent need to implement harm reduction interventions targeting PWID and to build a strong and enabling legal and policy environment in Ghana to support these efforts.

Hiv Aids

Background In this study data of three national surveys conducted among female sex workers (FSW), prison inmates and people who inject drugs (PWID) were presented and compared in relation to knowledge, attitude, and practises. Methods: The surveys were conducted in 2009 and 2010 and included 2546 PWID, 872 FSW and 5530 prison inmates. Knowledge, attitude and practises towards HIV were measured through similar questions for each category. Results: Over 90% of all participants had ever heard of HIV/AIDS, although only approximately half of them perceived themselves at risk of contracting HIV. More than 80% were able to correctly identify the ways of preventing the sexual transmission of HIV; while more than two-thirds did not use condom in their last sexual contact. Approximately 20% of prisoners and FSW had a history of injecting drugs. Among all participants who have injected drugs, prisoners had the highest unsafe injecting behaviour at the last injection (61%), followed by FSW (11%) and PWID (3%). Conclusions: Despite major efforts to control the HIV epidemic in Iran, the level of risk and vulnerability among prisoners, FSW and PWID is still high. The level of comprehensive knowledge about HIV/AIDS is relatively good; however, their risk perception of contracting HIV is low and high-risk behaviours are prevalent. Therefore, HIV prevention programs should be redesigned in a more comprehensive way to identify the best venues to reach the largest number of people at a higher risk of contracting HIV and decrease their risk overlaps and vulnerability factors.
