Abstract
Objective: To report the effectiveness of incorporating collars impregnated with 4% deltamethrin in dogs to control visceral leishmaniasis in Mariápolis/SP. To analyze the abundance of Lutzomyia longipalpis in the home environment during the period fitted dog collars in this municipality. Methods: Community intervention study between August 2022 and November 2024, fitted to dogs every six months dog collars in Mariápolis. The effectiveness of the intervention was analyzed through the survey positivity of dogs between the cicles canine carried out every six months and fitted in a regression model, vector abundance and frequency of human cases. Vector collections were carried out manually in homes, using light traps and Shannon. Results: Three canine surveys were carried out with respective prevalence: 13.6% (58/434); 10.62 (48/452); 3.84% (20/521). The Prevalence Ratio (PR) revealed an average of 71% of significant effectiveness in the fifth cycle and third survey. The overall average of Lu longipalpis in the home was 6.1 individuals. Discussion: The use of collars on dogs proved to be effective in reducing canine visceral leishmaniasis infection in Mariápolis/SP, in agreement with other studies carried out with collars with this objective. Conclusion: The use of collars with 4% deltamethrin insecticide was effective for controlling CVL.
