ABSTRACT

The methods adopted in this paper were as follows (1) The cost of the filariasis control was estimated to be direct cost and indirect cost; (2) Using the reduction rate of acute inflarrlmatory attack as the measurable indicator of control effectiveness; (3) Estimating the case number of acute inflammatory attack occurred after control year by year basing on the goodness by fitting in the reduction trend of acute inflammatory attack with hyperbola formula; (4) Assuming that the case number of acute inflammatory attack would be relatively stable at the same level of pre-control if filariasis control measures were not implemented;(5) The benefit from the filariasis control was estimated by transforming the increasing manworking day and sav1ng the mediclne expenses of patients due to the reduction of acute inflammatory attack. By allowing seven percent discount on cost and benefit, the total cost was 21 182 Yuan, the total benefit was 119 859 Yuan, the ratio of cost-benefit was 1 5. 7,implying that putting in one Yuan to filariasis control in this township may gain benefit 5. 7Yuan.
