HIV/AIDS prevention, care and treatment in the Region of the Americas: achievements, challenges and perspectives

ABSTRACT

The world has pledged within the Sustainable Development Goals to end the AIDS epidemic by 2030. In Latin America and the Caribbean in 2015 approximately 2.0 million people were living with HIV and an estimated 100 000 new infections occurred. Yet, significant progress has been made in the Region of the Americas over the past ten years in expanding access and coverage of HIV care and treatment and in achieving elimination of mother-to-child transmission of HIV and syphilis (1, 2). Regarding HIV prevention, and HIV stigma and discrimination new regional elimination targets have also been developed and endorsed (3). However, challenges still persist; among them, a 3% increase in the rate of new HIV infections in the Region between 2010 and 2015 (4). This special issue on HIV/AIDS prevention, care and treatment in the Region of the Americas achievements, challenges and perspectives provides an opportunity to present the current response to HIV/AIDS in the Region with a focus on three main areas HIV prevention, HIV care and treatment, and the elimination of mother-to-child transmission of HIV and congenital syphilis. A call for papers was issued in early 2016, and 12 articles were selected for publication—nine original research papers, one brief communication, one review, and one opinion and analysis article. The papers represent seven different countries as well as an overview of the Caribbean sub-region. A successful HIV prevention program requires a combination of structural, biomedical, and behavioral interventions that are mutually reinforcing, continually evaluated, and tailored to the needs and risks of specific key populations and others who are vulnerable to infection. Previous reports have shown the importance of combination prevention strategies (5). The special issue addresses this by focusing on HIV prevention strategies available for men who have sex with men in the United States (6), as well as the social vulnerability of transgender persons (7). Both papers highlight the need for tailored interventions that take into account local epidemiological contexts....
