Drawing on ethnographic research conducted from 2011 to 2015 and the authors' long-term engagement in diverse aspects of HIV and human rights advocacy in Brazil, this paper explores key elements of the Brazilian sex workers' movement response to HIV and the broader political factors that profoundly influenced its trajectory. We argue that the movement has constantly challenged representations of prostitution by affirming sex workers' roles as political actors, not just peer educators, in fighting the HIV epidemic and highlight their development of a sex positive and pleasure centred response that fought stigma on multiple fronts. Moments of tension such as the censorship of an HIV prevention campaign and implementation of 'test and treat' projects are analysed, as are the complex questions that Brazil's 2016 political and economic crisis evokes in terms of how to develop and sustain responses to HIV driven by communities but with material commitment from the State.

This article discusses limits and possibilities of the practice of a reflection group together with male perpetrators of violence against women. It is based on an ethnographic study, which included participant observation and interviews with the facilitators of a group held in a feminist non-governmental organization in partnership with the criminal justice system. Starting with the discussion of an emblematic scene, we argue in favor of this dialogue process as an alternative that could expand the limits of the judiciary approach.

We conducted a critical review of the literature on recurrent use of HIV testing in men who have sex with men (MSM). We performed a narrative review of the literature in which we analyzed the various conceptions on frequent testing over time, the implications for health programs, and the main social markers that influence the incorporation of HIV testing as routine care. Although it has existed since the 1990s, recurrent testing among MSM was frequently interpreted as increased exposure to HIV due to lack of condom use, and therefore as "unnecessary" testing.

This study aims to understand transgender people's access to the Brazilian public health care system in light of the new public policies for this group in Brazil. Our ethnographic study involved interviews with transgender women at a nongovernmental organization and a direct participant-observation study conducted 2 years later to observe how a new specialized service was providing health care for transgender people. Transgender people reported difficult personal life trajectories, marked by discrimination and binary standards, in their struggle to become recognized as women/men.

Sexuality education, its protocols and planning are contingent on an ever-changing political environment that characterizes the field of sexuality in most countries. In Brazil, human rights perspectives shaped the country's response to the AIDS epidemic, and indirectly influenced the public acceptability of sexuality education in schools. Since 2011, however, as multiple fundamentalist movements emerged in the region, leading to recurrent waves of backlashes in all matters related to sexuality, both health and educational policies have begun to crawl backwards.

Worldwide, HIV prevention is challenged to change because clinical trials show the protective effect of technologies such as circumcision, preexposure prophylaxis, and the suppression of viral load through antiretroviral treatment. In the face of demands for their implementation on population levels, the fear of stimulating risk compensation processes and of increasing riskier sexual practices has retarded their integration into prevention programs. In this article, following a narrative review of the literature on risk compensation using the PubMed database, we offer a critical reflection on the theme using a constructionist approach of social psychology integrated to the theoretical framework of vulnerability and human rights.
