HIV disproportionately affects men who have sex with men and transwomen in Latin America. Globally, efforts to map, enumerate, and describe male and transwomen sex workers (MTSWs) are limited. We mapped and described venue- and non-venue-based MTSWs and enumerated venuebased MTSWs in Lima, Peru's capital. With venue-based MTSWs, we identified and described the venues, SWs, and clients and enumerated the SWs. With non-venue-based MTSWs, we described SW offerings and SWs. Male SWs (MSWs) are concentrated downtown, with many moving online. Transwomen SWs (TSWs) are spread across metropolitan Lima, with fewer online. At venues, there are more TSWs than MSWs, TSWs reported more HIV and sexual risk behaviors, and MSWs had more female partners. Non-venue-based MSWs used condoms less than venue-based MSWs. Results support systematic efforts to describe hard-to-reach MTSWs and their different types of partners, all of whom have unique, differing needs for HIV/ STI education, prevention, testing, and care services.

In Peru, there is little information about the HIV care continuum. Therefore, we conducted a study to describe the HIV care continuum among male sex workers (MSWs) in Lima. We applied close-ended surveys with 209 MSWs about their engagement in the HIV care continuum and open-ended surveys with 34 MSWs who are people living with HIV (PLHIV) to explore their linkage to and retention in HIV care. Of 209 MSWs, only 71% (n=148) reported a lifetime HIV test and 56% (n=116) of all MSWs received confirmatory HIV test results. Of the 34 MSWs who are PLHIV, 76% had received HIV care at least once, but only 59% were currently in care, 50% were currently taking ART(antiretroviral therapy) and an even lower 32% had been on ART for 6 months or more. The primary reason for non-linkage to HIV care is the multiple visits to link at the Ministry of Health (MOH). Remaining in care was also challenging, particularly at non-governmental organizations (NGOs). Substantial barriers linking to and remaining in HIV care result in significant delays in linkage and high proportions of PLHIV that remain unlinked or become unstably linked following initial linkage. Urgent implementation science research is needed to facilitate linkage to HIV care and strengthen retention in HIV care post-linkage.

Objectives –To determine the socio-demographics, sexual practices, and HIV prevalence of male sex workers (MSWs), transwomen sex workers (TSWs), and their male clients in Lima, Peru.Methods –Following ethnographic mapping of sex work venues, we revisited randomly selected venues to survey MSWs, TSWs and their clients.Results –MSWs and TSW clients are more educated than MSW clients and TSWs. Only 50% of TSW clients have received HIV testing. Self-reported HIV positivity is highest among MSW clients and TSWs.Conclusion –Notable differences exist between MSWs and TSWs and their clients that can affect the health of these groups and warrant intervention.

Michelle C Chan,1 Angela M Bayer,1 Joseph R Zunt,2 Magaly M Blas,1 Patricia J Garcia1 1School of Public Health and Administration, Universidad Peruana Cayetano Heredia, Lima, Peru; 2Departments of Neurology and Global Health, University of Washington, Seattle, WA, USA Abstract: To solve increasingly complex global health problems, health professionals must collaborate with professionals in non-health-related fields. The Universidad Peruana Cayetano Heredia and University of Washington created the NIH-funded Kuskaya training program in response to the need for transformative global health training for talented graduates from all disciplines. Kuskaya is a 1-year, interdisciplinary training program that teaches Peruvian and US graduates critical skills related to public health research through the design and implementation of a collaborative research project in Peru. Between 2014 and 2018, the program has trained 33 fellows, of which one third were from non-health disciplines. The program is unique because it targets junior trainees from disciplines outside of the health field, the program’s curriculum is adapted to fit the fellows’ backgrounds and professional aspirations, and the structure of the program allows for collaboration within the cohort and encourages fellows to apply for additional funding and pursue advanced degrees. Lessons learned in designing the Kuskaya program include: 1) involving mentors in the fellow selection process, 2) involving fellows in existing lines of research to increase mentor involvement, 3) institutionalizing mentoring through regular works-in-progress meetings and providing mentoring materials, and 4) defining a core curriculum for all fellows while providing additional supplementary materials to meet each cohort’s needs, and evaluating their progress. Kuskaya provides an innovative model for bi-national, global health training to engage and provide a public health career pathway for all professionals. K

In Peru, there are few studies on male sex workers (MSWs), and existing studies explore limited subgroups or offer limited information about MSWs' perspectives. This study provides in-depth perspectives from 40 MSWs who work in downtown Lima (Cercado) and in surrounding urban neighborhoods (non-Cercado) through interviews on their identities, lives, and HIV/STI (sexually transmitted infection) risks and vulnerabilities. Findings are that entry into sex work links economy and affection, particularly among Cercado MSWs. Continued sex work cements this link, making it difficult to exit sex work and establish goals. Ties between economics and affections influence MSWs' perceived HIV/STI risks, vulnerabilities, and prevention practices. Although Cercado MSWs report higher HIV/STI risks and vulnerabilities than non-Cercado peers, they report fewer prevention practices given inability to buy condoms and acceptance of client offers of higher payment, especially clients they feel affection for. MSWs need support to strengthen their self-perceptions and define and pursue their goals in order to improve their HIV/STI prevention practices, health, and well-being.

ObjectivesTo describe the sociodemographic and sex work characteristics, recent sexual practices, HIV risk perception and testing history, and HIV and syphilis prevalence of Cercado (downtown) and non-Cercado (close urban) male sex workers (MSWs) in Lima, Peru.MethodsEighty-nine MSWs completed a self-administered survey and participated in HIV and syphilis testing.ResultsCercado MSWs had significantly lower median weekly earnings than non-Cercado MSWs (US$43 vs US$72, p=0.04). Most non-Cercado MSWs (81%) reported only insertive anal intercourse with male/transgender partners, while Cercado MSWs primarily reported only insertive (52%) or insertive and receptive (45%) anal intercourse (p=0.03). Consistent condom use was low with insertive and receptive anal intercourse in both subgroups. Among MSWs with recent female partners, condom use with the last partner was lower among Cercado versus non-Cercado MSWs for vaginal sex (37% vs 65%, p=0.04) and anal sex (27% vs 80%, p=0.01). More Cercado than non-Cercado MSWs (57% vs 42%) perceived high HIV risk (p=0.05) and Cercado MSWs had a much higher prevalence than non-Cercado MSWs of HIV (23% vs 4%, p=0.04) and syphilis (22% vs 0%, p=0.02) infections.ConclusionsMSWs in Lima are diverse and Cercado MSWs are 'just getting by,' engaging in more risk behaviours, and more likely to have HIV/STIs. Future research should identify, describe and carry out HIV/STI testing with broader groups of MSWs and their client and non-client partners. Prevention efforts should provide HIV/STI risk reduction education for MSWs and related subgroups who are currently not targeted such as female partners.

Violence experience can increase HIV risk behaviors; however, literature is scarce on violence among male sex workers (MSWs) globally. In 2014, 210 Peruvian MSWs (median age 24.9) were interviewed about their experience of physical, emotional, and sexual violence and condom use with non-paying intimate partners and clients and were tested for HIV. Multivariable models examined relationships between violence in the past 6 months, condomless anal intercourse (CLAI) in the past 3 months and HIV infection. HIV infection (24 %), CLAI (43 %), being a violence victim (42 %) and perpetrator (39 %) were common. In separate multivariable models, being a violence victim [adjusted prevalence ratio aPR = 1.49 (95 % CI 1.09-2.03)] and perpetrator [aPR = 1.39 (1.03-1.87)] were associated with CLAI. Further, being a victim [aPR = 1.65 (1.04-2.62)] was associated with HIV infection. Violence, which was significantly associated with CLAI and HIV infection, is common among Peruvian MSWs, reinforcing the importance of violence awareness and prevention as HIV risk-reduction strategies.

The recent avian influenza epidemic in Asia and the H1N1 pandemic demonstrated that influenza A viruses pose a threat to global public health. The animal origins of the viruses confirmed the potential for interspecies transmission. Swine are hypothesized to be prime mixing vessels due to the dual receptivity of their trachea to human and avian strains. Additionally, avian and human influenza viruses have previously been isolated in swine. Therefore, understanding interspecies contact on smallholder swine farms and its potential role in the transmission of pathogens such as influenza virus is very important., BMC Infectious Diseases v12:58, published on line 15 March 2012.
