[An alternative model for schistosomiasis control: the present status of the project in the State of Espírito Santo, Brazil].

An intervention study for schistosomiasis control is being carried out in the county of Afonso Cláudio, state of Espírito Santo, Brazil, having begun in February 1992. This study is an alternative response to classical control methods. The project is being developed using an interdisciplinary approach and involves both research and service institutions. The organization of health services at the primary care level is part of the project. Participant observation is seen as the methodological point of departure for guiding data collection and analysis and the intervention process in local reality. Control methods are restricted to the medical treatment given to all infected individuals and to improvements in the sanitation facilities available in the area. These methods are obviously integrated with the above-mentioned social actions. Consisting of three phases - pre-control, control (intervention), and final evaluation - the project is now in its intervention phase, lasting approximately three years.
