This proposal will support an interdisciplinary scientific meeting that will convene leading experts across the biomedical, public health, policy and social science arenas. With the goal of advancing a more comprehensive response to the interrelated challenges of sexual violence and HIV/AIDS, the programme seeks to develop strategies for ensuring that the prevention of sexual violence and exploitation can be made central to the global response to HIV and AIDS, as well as within biomedical, public health and social science research. The meeting outcomes will be synthesized in a meeting report that will form the basis of a comprehensive research program on sexual violence, HIV transmission and conflict. A small, two-day research planning meeting, held immediately prior to the Expert Group Meeting, will develop a phase 2, dynamic model of sexual violence and HIV risk that incorporates virological, epidemiological and mathematical approaches.
