Introduction Transgender (trans) men in sub‐Saharan Africa are a hidden and vulnerable population who may engage in sex work due to socio‐economic exclusion and lack of alternative employment opportunities. Little is known about HIV and sexually transmitted infection (STI) risk among trans men in this setting. We conducted a multi‐method study to characterize HIV/STI risk among trans men in Uganda. Methods Between January and October 2020, we enrolled 50 trans men into a cross‐sectional study through snowball sampling. Data were collected on socio‐demographic characteristics, sexual practices and depression. We conducted 20 qualitative interviews to explore: (1) descriptions of sexual practices that could increase HIV/STI exposure; (2) experiences of accessing public healthcare facilities; (3) perceptions of HIV or STI testing; (4) HIV and STI service delivery; and (5) drug and alcohol use. We used an inductive content analytic approach centring on descriptive category development to analyse the data. Results The median age was 25 years (interquartile range 23–28). The prevalence of HIV, syphilis and hepatitis B was 4%, 6% and 8%, respectively. We observed multiple levels of intersecting individual, interpersonal and structural stigmas. (1) Trans men reported transphobic rape motivated by interpersonal stigma that was psychologically traumatizing to the survivor. The resultant stigma and shame hindered healthcare access. (2) Structural stigma and economic vulnerability led to sex work, which increased the risk of HIV and other STIs. Sex work stigma further compounded vulnerability. (3) Individualized stigma led to fear of disclosure of gender identity and HIV status. Concealment was used as a form of stigma management. (4) Multiple levels of stigma hampered access to healthcare services. Preference for trans‐friendly care was motivated by stigma avoidance in public facilities. Overall, the lived experiences of trans men highlight the intertwined relationship between stigma and sexual health. Conclusions In this sample from Uganda, trans men experienced stigma at multiple levels, highlighting the need for gender‐sensitive healthcare delivery. Stigma reduction interventions, including provider training, non‐discrimination policies, support groups and stigma counselling, could strengthen uptake and utilization of prevention services by this marginalized population.

BACKGROUND For HIV-serodiscordant couples, integrated delivery of antiretroviral therapy (ART) for HIV-positive partners and time-limited pre-exposure prophylaxis (PrEP) for negative partners virtually eliminates HIV transmission. Standardized messaging, sensitive to the barriers and motivators to HIV treatment and prevention, is needed for widespread scale-up of this approach. METHODS Within the Partners Demonstration Project, a prospective interventional project among 1,013 serodiscordant couples in Kenya and Uganda, we offered ART to eligible HIV-positive partners and PrEP to HIV-negative partners prior to ART initiation and through the HIV-positive partner’s first six months of ART use. We conducted individual and group discussions with counseling staff to elicit the health communication framework and key messages about ART and PrEP that were delivered to couples. RESULTS Counseling sessions for serodiscordant couples about PrEP and ART included discussions of HIV serodiscordance, PrEP and ART initiation and integrated use, and PrEP discontinuation. ART messages emphasized daily, lifelong use for treatment and prevention, adherence, viral suppression, resistance, side effects, and safety of ART during pregnancy. PrEP messages emphasized daily dosing, time-limited PrEP use until the HIV-positive partner sustained six months of high adherence to ART, adherence, safety during conception, side effects, and other risks for HIV. CONCLUSION Counseling messages for HIV-serodiscordant couples are integral to the delivery of time-limited PrEP as a ‘bridge’ to ART-driven viral suppression. Their incorporation into programmatic scale-up will maximize intervention impact on the global epidemic.

Introduction: HIV self-testing (HIVST) and oral pre-exposure prophylaxis (PrEP) are complementary, evidence-based, selfcontrolled HIV prevention tools that may be particularly appealing to sex workers. Understanding how HIVST and PrEP are perceived and used by sex workers and their intimate partners could inform prevention delivery for this population. We conducted qualitative interviews to examine ways in which HIVST and PrEP use influence prevention choices among sex workers in Uganda. Methods: Within a randomized trial of HIVST and PrEP among 110 HIV-negative cisgender women, cisgender men and transgender women sex workers (NCT03426670), we conducted 40 qualitative interviews with 30 sex workers and 10 intimate partners (June 2018 to January 2020). Sex worker interviews explored (a) experiences of using HIVST kits; (b) how HIVST was performed with sexual partners; (c) impact of HIVST on PrEP pill taking; and (d) sexual risk behaviours after HIVST. Partner interviews covered (i) introduction of HIVST; (ii) experiences of using HIVST; (iii) HIV status disclosure; and (iv) HIVST's effect on sexual behaviours. Data were analysed using an inductive content analytic approach centering on descriptive category development. Together, these categories detail the meaning of HIVST and PrEP for these qualitative participants. Results: Using HIVST and PrEP was empowering for this group of sex workers and their partners. Three types of empowerment were observed: (a) economic; (b) relational; and (c) sexual health. (i) Using HIVST and PrEP made sex without condoms safer. Sex workers could charge more for condomless sex, which was empowering economically. (ii) Self-testing restored trust in partners' fidelity upon being reunited after a separation. This trust, in combination with condomless sex made possible by PrEP use, restored intimacy, empowering partnered relationships. (iii) HIVST and PrEP enabled sex workers to take control of their HIV prevention efforts and avoid the stigma of public clinic visits. In this way they were empowered to protect their sexual health. Conclusions: In this sample, sex workers' use of HIVST and PrEP benefitted not only prevention efforts, but also economic and relational empowerment. Understanding these larger benefits and communicating them to stakeholders could strengthen uptake and use of combination prevention interventions in this marginalized population.
