Abstract: | We consider an approach to built on a score summarizing some demographic, social, geographic and parasitologic data for purpose of measuring the health impact of schistosomiasis. Operational definitions are given for the social, ecological and medical variables and for the survey design. Twenty villages from the Bam-Kongoussi district were kept for the survey, giving a sample of 11,396 peoples. The process of the survey is described. The overall response rate is 63%. The sensitivity of the survey's results in regard to the non-responses is considered along with the possibility to implement a call back survey. |
