[The use of risk factor determination for schistosomiasis in endemic areas in Brazil].
This study shows the results of risk factor determination for infection with Schistosoma mansoni in endemic areas in Brazil. An association was observed between infection with S. mansoni and a number of general conditions: absence of drinking water in the home, low individual income, illiteracy, and residence in an endemic area for more than five years. In addition to these conditions there was also association with a number of habits (risk factors): agricultural and domestic activities in open water supplies, swimming, and fishing. Analysis of the general conditions that may determine these risk factors indicated that provision of drinking water in the home and access to treatment are basic measures that could be adopted in many cases in order to prevent or control the morbidity of the disease. The efficacy of the use of risk factor determination for indication of control measures for this disease is questioned.
