Cost-effectiveness analysis in Chagas' disease vectors control interventions
Universidade Federal do Rio de Janeiro, Núclo de Pesquisas de Produtos Naturais, Rio de Janeiro, Brasil
After a large scale field trial performed in central Brazil envisaging the control of Chagas' disease vectors in an endemic area colonized by Triatoma infestans and T. sordida the cost-effectiveness analysis for each insecticide/formulation was performed. It considered the operational costs and the prices of insecticides and formulations, related to the activity and persistence of each one. The end point was considered to be less than 90% of domicilliary unitis (house + annexes) free of infestation. The results showed good cost-effectiveness for a slow-release emulsifiable suspension (SRES) based on PVA and containing malathion as active ingredient, as well as for the pyrethroids tested in this assay-cyfluthrin, cypermethrin, deltamethrin and permethrin.
