AbstractBackgroundAssessment of geographical heterogeneity of HIV among men who have sex with men (MSM) and people who inject drugs (PWID) can usefully inform targeted HIV prevention and care strategies. We aimed to measure HIV prevalence and identify hotspots of HIV infection among MSM and PWID in Nigeria.MethodsWe included all MSM and PWID accessing HIV testing services across seven prioritized states (Lagos, Nasarawa, Akwa Ibom, Cross Rivers, Rivers, Benue and the Federal Capital Territory) in three geographic regions (North Central, South South, South West) between Oct 1, 2016 and Sept 30, 2017. We extracted data from national testing registers, georeferenced all HIV test results aggregated at the level of Local Government Areas (LGAs), and calculated HIV prevalence. We calculated and compared HIV prevalence from our study to the integrated biological and behavioral surveillance survey (IBBSS) 2014 and used global spatial autocorrelation and hotspot analysis to highlight patterns of HIV infection, and to identify areas of significant clustering of HIV cases.FindingsA positive HIV test was reported in 12.1% (95%CI 9.7-13.1) and 11.8% (95%CI 9.3-12.7) of the 26,423 MSMs and 9,474 PWIDs, respectively. Global spatial autocorrelation Moran’s I statistics revealed a clustered distribution of HIV infection among MSMs and PWIDs with a <5% and <1% likelihood that this clustered pattern could be due to chance respectively. Significant clusters of HIV infection (Getis-Ord-Gi* statistics) confined to the North Central, South-South regions were identified among MSM and PWID. Compared to the 2014 IBBSS our results suggest an increased HIV prevalence among PWID and a substantial decrease among MSM.InterpretationThis study identified geographical areas to prioritize for control of HIV infection among MSM and PWID, thus demonstrating that geographical information system technology is a useful tool to inform public health planning for interventions for epidemic control of HIV infection.FundingData used for this study was collected from Key Population program in Nigeria through PEPFAR/USAID. OK was funded by the Swiss National Science Foundation (grant no 163878).

Background The assessment of geographical heterogeneity of HIV among men who have sex with men (MSM) and people who inject drugs (PWID) can usefully inform targeted HIV prevention and care strategies. Objective We aimed to measure HIV seroprevalence and identify hotspots of HIV infection among MSM and PWID in Nigeria. Methods We included all MSM and PWID accessing HIV testing services across 7 prioritized states (Lagos, Nasarawa, Akwa Ibom, Cross Rivers, Rivers, Benue, and the Federal Capital Territory) in 3 geographic regions (North Central, South South, and South West) between October 1, 2016, and September 30, 2017. We extracted data from national testing registers, georeferenced all HIV test results aggregated at the local government area level, and calculated HIV seroprevalence. We calculated and compared HIV seroprevalence from our study to the 2014 integrated biological and behavioural surveillance survey and used global spatial autocorrelation and hotspot analysis to highlight patterns of HIV infection and identify areas of significant clustering of HIV cases. Results MSM and PWID had HIV seroprevalence rates of 12.14% (3209/26,423) and 11.88% (1126/9474), respectively. Global spatial autocorrelation Moran I statistics revealed a clustered distribution of HIV infection among MSM and PWID with a <5% and <1% likelihood that this clustered pattern could be due to chance, respectively.

Background: This paper presents the prevalence of human immuno deficiency virus (HIV) infection among men who have sex with men (MSM) attending integrated counselling and testing Centres (ICTC) in selected districts of Karnataka.Methods: A cross sectional study was done at ICTCs. Men and transgenders coming with referral slips from targeted intervention (TI), non-government organizations (NGOs) were considered as MSMs. The basic demographic data, HIV test result and details of post- test counselling were collected in specific format. Data from 13 districts was obtained from April 2009 to March 2010 and comparing the prevalence of HIV among MSM in HIV sentinel surveillance (HSS).Results: Out of 8,276 MSMs in 13 districts, 2808 (33.9%) visited ICTCs with TI NGOs referral slips and were tested for HIV once in a year. The overall prevalence of HIV was 8.6%. Prevalence was highest (17.3%) among men in the age group of 41 to 45 years, illiterates (11.5%), unemployed (11.2%) and divorced and separated (13.3%) and widowed (13.6%) MSMs. Among those tested, 97.7% of MSM underwent post-test counselling and collected their report. The highest HIV prevalence was among MSMs from Mysore district (20.1%), followed by Udupi (19.9%) and Bagalkot (10.6%). Rest of all the other districts had less than 10% of HIV prevalence.Conclusions: The uptake of HIV testing among the MSM with referral slips was low in Karnataka. The prevalence level differs in various districts. There is need for more focused and effective counselling by peer educators for correct and consistent condom usage among illiterate, widowed and unemployed MSMs.

ObjectiveTo examine the trends of HIV prevalence, risk behaviours and HIV testing among men who have sex with men (MSM) in Nanjing.DesignFive consecutive cross-sectional surveys.SettingNanjing, China.Primary and secondary outcome measuresHIV and syphilis prevalence, HIV testing rate and factors associated with HIV infection; demographic characteristics and behaviours.Results649, 669, 577, 633, 503 MSM were recruited from 2013 to 2017. HIV prevalence was 9.9%, 12.3%, 12.5%, 9.8% and 10.1%, respectively. Syphilis prevalence decreased with a range from 10.6% to 5.6%. Risk behaviours like unprotected anal intercourse (UAI) and unprotected virginal sex in the past 6 months decreased, but multiple sex partners and ever used rush popper rose significantly. MSM tested for HIV in the previous year remained stable from 57.0% to 64.1% (P=0.633). Multivariate analysis showed that tested for HIV in the past year was protective factor against HIV infection. MSM who had UAI in the past 6 months, sex role as receptive and dual, diagnosed with sexually transmitted diseases (STDs) in the past year and currently syphilis infected were risk factors for HIV infection.ConclusionsWe observed stable high HIV prevalence, a steady HIV testing rate, decreasing syphilis prevalence and UAI among MSM in Nanjing. However, rush popper use rose dramatically. The HIV preventive strategies for MSM including condom promotion, HIV testing expansion and reduction of rush popper use, STDs screening and standardised treatment should be strengthened.

HIV prevalence is still rapidly increasing among Chinese men who have sex with men (MSM). The Internet also makes it easier for MSM to have casual partners. This study aims to evaluate the trend of Internet-based sex-seeking behavior of MSM and its impact on HIV prevalence, the distribution of HIV subtype strains, and transmitted drug resistance rates. A serial cross-sectional study was conducted from 2009 to 2014. Of the 1,981 MSM, 50.5% (1,000/1,981) mainly sought homosexual partners through the Internet (Internet-based MSM, IBM). The proportion of IBM among total MSM subjects increased from 43.3% to 61.5% (p<0.001). HIV prevalence of IBM increased from 5.7% to 20.7%, while that of non-Internet-based MSM (NIBM) increased from 7.0% to 14.7%. A relative higher proportion of NIBM were infected with HIV CRF01_AE subtype than IBM (79.5% versus 72.2%, p=0.52). Multivariable analysis found IBM had a significantly higher HIV prevalence than NIBM (13.2% versus 10.5%, aOR = 1.4, 95% CI [1.0–1.9]). Being a migrant non-Shenyang resident MSM (aOR = 1.9, 95% CI [1.3–2.9]) and occasionally/never using condoms with casual homosexual partners (aOR = 1.7, 95% CI [1.1–2.6]) were two distinct risk factors for HIV infection in IBM. More efforts should be targeted towards developing interventions aimed at IBM, particularly migrant MSM and who engage in UAI with casual homosexual partners.

Background: HIV infection is prevalent among men who have sex with men (MSM), and sexual roles may be important factors related to it. This study aims to describe the sexual roles, risky sexual behaviors and HIV prevalence among MSM, and to determine associated factors for HIV prevalence. Methods: A convenient sampling method was used to recruit participants in a non-government organization in Changsha, China. The participants were asked to complete a 38-item self-administered questionnaire regarding demographic characteristics and risky sexual behaviours before collecting blood samples for HIV testing. Chi-square tests and logistic regression analysis were conducted with the Statistical Package for the Social Sciences Version 18.0 and other indexes were statistically described. Results: A total of 601 MSMs who came to a local non-government organization for voluntary counseling and testing completed a pencil-and-paper survey and were tested for HIV. The overall HIV prevalence of this sample was 13.3%, and that of the bottoms (16.3%) was similar to the versatiles (15.9%) but higher than the tops (6.1%). Bivariate analyses showed that there were significant differences in age, marital status, monthly income, sexual orientation, age at first sex, sex of the first sex partner, sex with a woman in the last 6 months, oral sex with a man in the last 6 months and role of oral sex among 3 subgroups of MSM (p < 0.05). Multivariate analyses indicated that MSMs who played the role of either the bottoms or the versatiles were more likely to be HIV positive than the tops. While MSMs who used condoms in anal sex in the last 6 months, had sex with a woman in the last 6 months or had oral sex with a man in the last 6 months were less likely to be HIV positive. Conclusion: Different sexual roles are associated with high-risk sexual behaviors among MSMs and their HIV infection status. Further research should target preventive interventions, and improve the effectiveness of the intervention according to the characteristics of the subgroups to reduce the HIV transmission among Chinese MSM.

Abstract Background Substantial number of women who deliver at home (WDH) are not captured in prevention of mother-to-child transmission (PMTCT) services. This delays HIV infection detection that negatively impacts endeavours to fight the HIV pandemic and the health of mothers and children. The study objective was to determine the feasibility of home-based HIV testing and linking to care for HIV services among WDH in Geita District Council, Tanzania.Methods A longitudinal household survey was conducted. The study involved all mentally-able women who delivered within two years (WDTY) preceding the survey and their children under the age of two. The study was conducted in Geita District Council in Geita Region, Tanzania from June to July 2017. Geita is among the region with high HIV prevalence and proportion of women delivering at home.Results Of the 993 women who participated in the study, 981 (98.8%) accepted household-based HIV counselling and testing (HBHCT) from the research team. HIV prevalence was 5.3% (52 women). HBHCT identified 26 (2.7%) new HIV infections; 23 (23.4%) were those tested negative at ANC and the remaining three (0.3%) were those who had no HIV test during the ANC visit. Among the 51 HIV+ women, 21 (40.4%) were enrolled in PMTCT services. Of the 32 HIV+ participants who delivered at home, eight (25.8%) were enrolled in the PMTCT compared to 100 percent (13/13) of the women who delivered at a health facility.Conclusion HBHCT uptake was high. HBHCT detected new HIV infection among WDH as well as seroconversion among women with previously negative HIV tests. The study findings emphasize the importance of extending re-testing to women who breastfeed. HBHCT is feasible and can be used to improve PMTCT services among WDH.

ObjectivesTo estimate HIV prevalence and associated risk factors among men who have sex with men (MSM) in Dar es Salaam, Tanzania following the implementation of the national comprehensive package of HIV interventions for key population (CHIP).DesignA cross-sectional survey using respondent-driven sampling.SettingDar es Salaam, Tanzania’s largest city.ParticipantsMen who occasionally or regularly have sex with another man, aged 18 years and above and living in Dar es Salaam city at least 6 months preceding the study.Primary outcome measureHIV prevalence was the primary outcome. Independent risk factors for HIV infection were examined using weighted logistics regression modelling.ResultsA total of 777 MSM with a mean age of 26 years took part in the study. The weighted HIV prevalence was 8.3% (95% CI: 6.3%–10.9%) as compared with 22.3% (95% CI: 18.7%–26.4%) observed in a similar survey in 2014. Half of the participants had had sex with more than two partners in the month preceding the survey. Among those who had engaged in transactional sex, 80% had used a condom during last anal sex with a paying partner. Participants aged 25 and above had four times higher odds of being infected than those aged 15–19 years. HIV infection was associated with multiple sexual partnerships (adjusted OR/AOR, 3.0; 95% CI: 1.8–12.0), not having used condom during last sex with non-paying partner (AOR, 4.1; 95% CI: 1.4–7.8) and ever having engaged in group sex (AOR, 3.4; 95% CI: 1.7–3.6).ConclusionHIV prevalence among MSM in Dar es Salaam has decreased by more than a half over the past 5 years, coinciding with implementation of the CHIP. It is nonetheless two times as high as that of men in the general population. To achieve the 2030 goal, behavioural change interventions and roll out of new intervention measures such as pre-exposure prophylaxis are urgently needed.

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.
