Stratification for the entomological surveillance of dengue

[摘要] INTRODUCTION: the entomological surveillance is used to determine the changes in the geographical distribution of the vectors and to obtain the relative measurements of their populations in the course of time, in order to facilitate prompt and adequate decisions about interventions. OBJECTIVES: to submit a stratification system, based on some indicators of the Aedes aegypti eradication program, which allows the entomological surveillance of dengue in Boyeros municipality. METHODS: A retrospective descriptive study was made with the following indicators: house index, reservoir index, Breteau index, positive neighbourhood index, collected sample index, useful and non useful reservoir index by season (dry and rainy). RESULTS: the entomological indicators allowed determining the most risky health areas during the two seasons. The infestation index per house increases in the rainy seasons as well as the number of non useful reservoirs that are positive to the vector. In the stratification, the most risky areas were Boyeros and Armada during the dry season, followed by Mulgoba and Wajay in the rainy season. CONCLUSIONS: the stratification system presented in this paper responds to the integration of the entomological indicators that would make it possible to evaluate the functioning of the program and to promptly act in the anti-vector eradication campaign.
