Interventions against sexually transmitted infections (STI) to prevent HIVinfection

STIs have taken on a more important role with the advent of the HIV/AIDS ep idemic, and there is good evidence that their Control can reduce HIV transm ission. The challenge is not just to develop new interventions, but to iden tify barriers to the effective implementation of existing tools, and to dev ise ways to overcome these barriers. This 'scaling-up' of effective strateg ies will require an international and a multisectoral approach. It will req uire the formation of new partnerships between the private and public secto rs and between governments and the communities they represent.
