Background • Transgender - diverse population of people whose gender identity or expression differs from their natal sex • Dearth of data on transgender men, sex work, and HIV • 24 – 75% of transgender women engage in sex work in U.S. • 54% – 80% of transgender women in Asia-Pacific had history of sex work • 1 Herbst JH, et al.

HIV Epidemiology: Global Meta-analysis RR: 4.02 compared to FSW Data limitations: sampling methods; population is often subsumed under “men who have sex with men” or “female sex workers” in research; little research specifically about transgender sex workers
Community Voices: Stigma and Resilience Stigma persists. Some of my family members still do not accept me as a hijra. But, at the end of the day, I forget all this pain when I think about the love and respect I have received not only from the hijra community, but from all sex workers and sexual minorities and from many others who work for our community. It will take time to eliminate stigma . . . However, the movement has started and we are on the right track. JoyaSikder, President of the National Platform of Sex Workers, Bangladesh
Intervention Opportunities • Evidence suggests that best interventions are • Multi-level, addressing structural barriers as well as behavior change • Community-led and grounded in empowerment • New biomedical interventions hold promise • PrEP: iPrex included transgender women, however, studies statistically powered to provide results for this population are needed • Early ART: PARTNER study suggest efficacy for insertive and receptive anal sex as well as vaginal sex. Neovaginal transmission risks are unknown • Microbicides: It will be important for rectal microbicide trails to include enough trans women to determine efficacy
Modelling Scenarios 2 distinct epidemiologic settings: Lima, Peru and San Francisco, U.S.A 10 year Intervention period with stable partners Number of new HIV infections with clients Baseline PrEP Early ART Transactions for the same 50% reduction ? Years
Modelling Results A=condoms with clients; B= condoms with partners; C=number of commercial transactions; D=PrEP; E = test and treat
Country Case Studies • Research and interventions must be informed by local contexts and adapted to different settings in order to have the most impact • Most countries lack basic HIV prevalence data on transgender sex workers
Complex Legal and Policy Environments *Laws and policies vary by state within US and other countries
Implications of Modeling and Case Studies • Combination interventions are essential • Prevention programmes must be tailored to the context • Structural and psychosocial factors are key to changing proximal determinants • More research is needed
Conclusion • Trans women sex workers bear a heavy burden of HIV • Researchers must collect trans-specific data that clearly separates trans women sex workers from male and non-trans female sex workers • There is an urgent need for evidence-based interventions that are effective, acceptable and appropriate for trans sex workers
