PLANO DE AÇÃO PARA INTENSIFICAÇÃO DA VIGILÂNCIA E CONTROLE DA LEISHMANIOSE VISCERAL (PACLV) NO MUNICÍPIO DE CORUMBÁ/MS: COLETA DE FLEBOTOMÍNEOS

Abstract

Visceral Leishmaniasis (VL) is a neglected zoonosis of global distribution, endemic in Brazil, with the municipality of Corumbá, Mato Grosso do Sul, classified as an area of intense disease transmission. Given the severity of VL, the implementation of the Action Plan for the Combat of Visceral Leishmaniasis (PACLV) is justified as a control alternative for the zoonosis. The main objective of this study was to carry out the entomological monitoring of the leishmaniasis vector population in the Popular Nova neighborhood of Corumbá/MS during the first stage of the PACLV in 2022, evaluating the epidemiological aspects of this activity. The research was characterized as an exploratory, quantitative, and field-based study. Phlebotomine collection was performed between March and November 2022 using CDC traps installed in both the intradomicile and peridomicile environments. Statistical analysis included the Paired T-test and the Kruskal Wallis test. A total of 7,147 phlebotomine vectors were captured in the Popular Nova neighborhood during the period. The results showed that 67.8% of the vectors were captured in intradomiciliary traps, compared to 32.2% in the peridomicile, demonstrating a statistically significant difference (p=0.0116) related to location. The months of April and May recorded the highest number of captures, with a statistically significant difference between months (p = 0.004287). The predominance of the vector inside homes suggests a greater risk of exposure for residents. The conclusions indicate that climatic variation influences the quantity of collected phlebotomines, and an increase in the occurrence of Lutzomyia cruzi is noticeable. It is recommended that the PACLV control strategies focus intensively on the intradomiciliary area, including residual chemical control and housing improvements (screens on windows and doors, sealing cracks).
