PLAN International have recently extended their area of operation in Zimbabwe to include the Honde Valley and have agreed to provide funding for the HIV intervention programme for a minimum period of four years. PLAN maintain routine records on a number of key impact indicators so that the projects they sponsor can be assessed. It may be possible to develop these systems so that they provide information on indicators of the impact of the HIV epidemic and the effectiveness of AIDS control activities - eg: programme coverage and success in targeting - which could be used in this study and for long-term monitoring purposes.
