The Regional Workshop on Strengthening Gender Based Violence and HIV Response and Services in Sub-Saharan Africa was organized jointly by Liverpool VCT, Care and Treatment (LVCT), the World Health Organization (WHO) and the Sexual Violence Research Initiative (SVRI). It was supported by Comic Relief through Trocaire, the United Nations Trust Fund to End Violence against Women, the Elton John AIDS Foundation, and Population Council. The workshop brought together key thinkers and practitioners from the Eastern and Southern Africa Region (ESAR) to discuss existing models in GBV and HIV integration and reflect on the extent to which these models have been applied in the actual delivery of services. The participants also discussed the challenges and opportunities for integration of GBV into HIV responses, and debated on possibilities for translating theory into practice. The main goal of the workshop was to explore existing evidence and gaps in the evidence in GBV, and HIV, as well as the challenges, and identify opportunities in the implementation of GBV programmes in HIV responses. The specific workshop objectives were: To establish the evidence for GBV/HIV programming and outlining the challenges and opportunities to development of sustained evidence; To identify barriers and enablers to GBV/HIV programming and evaluation of programmes and outlining opportunities for GBV/HIV programming in existing HIV response interventions (HTC, PMTCT, Care and Treatment, Prevention) for general and key affected populations; To develop action plans for integrating and evaluating interventions within HIV programming by determining GBV/HIV programming priorities.
