    Background International and global organisations advocate targeting interventions to areas of high HIV prevalence (ie, hotspots). To better understand the potential benefits of geo-targeted control, we assessed the extent to which HIV hotspots along Lake Victoria sustain transmission in neighbouring populations in south-central Uganda. Methods We did a population-based survey in Rakai, Uganda, using data from the Rakai Community Cohort Study. The study surveyed all individuals aged 15–49 years in four high-prevalence Lake Victoria fishing communities and 36 neighbouring inland communities. Viral RNA was deep sequenced from participants infected with HIV who were antiretroviral therapy-naive during the observation period. Phylogenetic analysis was used to infer partial HIV transmission networks, including direction of transmission. Reconstructed networks were interpreted through data for current residence and migration history. HIV transmission flows within and between high-prevalence and low-prevalence areas were quantified adjusting for incomplete sampling of the population. Findings Between Aug 10, 2011, and Jan 30, 2015, data were collected for the Rakai Community Cohort Study. 25 882 individuals participated, including an estimated 75·7% of the lakeside population and 16·2% of the inland population in the Rakai region of Uganda. 5142 participants were HIV-positive (2703 [13·7%] in inland and 2439 [40·1%] in fishing communities). 3878 (75·4%) people who were HIV-positive did not report antiretroviral therapy use, of whom 2652 (68·4%) had virus deep-sequenced at sufficient quality for phylogenetic analysis. 446 transmission networks were reconstructed, including 293 linked pairs with inferred direction of transmission. Adjusting for incomplete sampling, an estimated 5·7% (95% credibility interval 4·4–7·3) of transmissions occurred within lakeside areas, 89·2% (86·0–91·8) within inland areas, 1·3% (0·6–2·6) from lakeside to inland areas, and 3·7% (2·3–5·8) from inland to lakeside areas. Interpretation Cross-community HIV transmissions between Lake Victoria hotspots and surrounding inland populations are infrequent and when they occur, virus more commonly flows into rather than out of hotspots. This result suggests that targeted interventions to these hotspots will not alone control the epidemic in inland populations, where most transmissions occur. Thus, geographical targeting of high prevalence areas might not be effective for broader epidemic control depending on underlying epidemic dynamics.

    BackgroundIn sub-Saharan Africa (SSA), disclosure of HIV status to children remains low. Few studies have examined how children navigate and come to terms with their HIV status. The aim of this study was to explore experiences of children about disclosure of their HIV status.MethodsBetween October 2020 and July 2021, 18 purposively selected children aged between 12-17 whose HIV status had been disclosed to them by their caregivers or healthcare providers (HCPs) were recruited for this study. We conducted 18 in-depth interviews (IDIs) to collect data for this study. Data were analyzed using the semantic thematic analysis approach.ResultsPrimary data obtained through IDIs revealed that disclosure of HIV status to children occurred as a one-time event without pre-disclosure preparatory planning or focused post disclosure follow-up counseling irrespective of the discloser. Post disclosure psycho-social experiences elicited mixed responses. Some children experienced insults and belittlement and stigma and discrimination in the family and community for out-of-school children and at school for school-going children. Positive disclosure experiences involved receiving support to improve ART adherence through constantly being reminded to take their medications timely at the workplace, by supervisors, for working children and by teachers, at school for school-going children.ConclusionsThis research contributes to knowledge about children' s experiences of being HIV infected and can specifically be used to improve disclosure strategies

    This article reports the effect of a demand-creation intervention trial on couples’ HCT uptake among married or cohabiting individuals who had never received couples’ HCT.Background: Uptake of couples’ HIV counseling and testing (couples’ HCT) services remains largely low in most settings. We report the effect of a demand-creation intervention trial on couples’ HCT uptake among married or cohabiting individuals who had never received couples’ HCT. Methods: This was a cluster-randomized intervention trial implemented in three study regions with differing HIV prevalence levels (range: 9–43 %) in Rakai district, southwestern Uganda, between February and September 2014. We randomly assigned six clusters (1:1) to receive the intervention or serve as the comparison arm using computer-generated random numbers. In the intervention clusters, individuals attended small group, couple and male-focused interactive sessions, reinforced with testimonies from ‘expert couples’, and received invitation coupons to test together with their partners at designated health facilities. In the comparison clusters, participants attended general adult health education sessions but received no invitation coupons. The primary outcome was couples’ HCT uptake, measured 12 months post-baseline. Baseline data were collected between November 2013 and February 2014nwhile follow-up data were collected between March and April 2015. We conducted intention-to-treat analysis using a mixed effects Poisson regression model to assess for differences in couples’ HCT uptake between the intervention and comparison clusters. Data analysis was conducted using STATA statistical software, version 14.1. Results: Of 2135 married or cohabiting individuals interviewed at baseline, 42 % (n = 846) had ever received couples’ HCT. Of those who had never received couples’ HCT (n = 1,174), 697 were interviewed in the intervention clusters while 477 were interviewed in the comparison clusters. 73.6 % (n = 513) of those interviewed in the intervention and 82.6 % (n = 394) of those interviewed in the comparison cluster were interviewed at follow-up. Of those interviewed, 72.3 % (n = 371) in the intervention and 65.2 % (n = 257) in the comparison clusters received HCT. Couples’ HCT uptake was higher in the intervention than in the comparison clusters (20.3 % versus 13.7 %; adjusted prevalence ratio (aPR) = 1.43, 95 % CI: 1.02, 2.01, P = 0.04). Conclusion: Our findings show that a small group, couple and male-focused, demand-creation intervention reinforced with testimonies from ‘expert couples’, improved uptake of couples’ HCT in this rural setting.
