Habtamu Argaw
A study was conducted to test the application of the so called "indirect questionnaire approach" using key informants, for the assessment of high risk areas for onchocerciasis. The objective was to determine the validity, cost-effectiveness and operational feasibility of questionnaires. Questionnaires were designed and distributed to six junior high schools via the education officer and administered to 1385 students through their teachers. Validation test was undertaken on 1345 students of the

Using the Spearman rank correlation analysis on the positive response rate on the indictors of onchocerciasis to the parasitological results,all the questions were negatively correlated, due to probably poor perception, immune tolerance and lack of attention to the manifestations in the high risk areas.Report of "nodule" was the only significantly correlated. The use of educational sector was found to be feasible. The indirect questionnaire approach was seven times less expensive, with comparable time and coverage as the biomedical approach. The study area was found to have high prevalence (15.5%) of microfilarial rate in young teenagers, and the endemic area wider. Further study is recommended to assess the applicability of the approach, in different socioeconomic and demographic situations
