    Summary
    Self-administered questionnaries, distributed by existing administrative channels to village party chairman, head-teachers and schoolchildren, showed good diegnostic perfomance for the qualitative assessment of unirary schistosomiasis endemicity. At a cost 34 times below that of the WHO- recommended persitological screening strategy, the schoolchildren's questionnaire allowed the screening of 75 out of 77 school of a rural Tanzanian district in six weeks, and the exclusion of school not at high risk for urinary schistosomiasis with over 90% confidence. The headteacher and party questinnalres made it possible to assess the perceived important of a spectrum of discease and symptoms, among which was schistosomiasis. The priroty rank of schistosomiasis control was stronglycorreled with the prevalence rate of the disease in the community. The queationnaires also looked for the prioritization of health among other community issues and thus contributed important for planning at district level. Standardized monthly dieases reports, sent by all primary health services, were also analysed. They allowed a zonal schistosomiasis endemicity classification
