Phase III's objective is to initiate and complete a community mobilization intervention aimed at reducing HIV incidence and prevalence among youth. The intervention will consist of guiding C2P coalitions through a strategic planning process that will result in the development and implementation of a local action plan. The action plan will focus on changing structural elements of the affected communities that are believed to be associated with youth HIV acquisition and transmission. The effectiveness of the intervention will be evaluated by tracking venues where the population of interest congregates and trends in risk factors associated with HIV acquisition and transmission.
