In 2010, GHC was awarded PEPFAR funding through a five-year cooperative agreement with U.S. CDC to undertake HIV prevention with MARPs in Cabo Delgado, Inhambane and Nampula provinces. The project aims to reduce risk for HIV infection among sex workers, drug users and men who have sex with men through peer education. Peer educators distribute condoms and health information, encourage their peers to test for HIV, and use GHC tools to initiate behavior change through concrete action. This project combines the strengths of GHC in theory-based interventions with Population Services International’s (PSI) long experience in Mozambique, their network of outreach workers, excellence in social marketing and infrastructure. GHC is responsible for training and developing materials for health information, training, and behavior change. A consortium lead by PSI is responsible for overall implementation. Through this project we are able to shape and improve outreach services to MARPs in three provinces.
