Abstract
Objectives: We investigated whether the application of the LIRAa monitoring tool (Aedes aegypti Fast Infestation Survey) had an impact on lowering the Dengue incidence rate in the municipalities of the country. Methods: Two methods were all used, the first was difference in differences (DiD) and Event Study, being both estimated by balanced panel data. The study was carried out considering the 2001-2016 period. The National Information and Injuries System (SINAN), National Sanitation Information System (SNIS), National Institute of Space Research (INPE) and the Brazilian Institute of Geography and Statistics (IBGE) were the main data sources. Results: By using the method of difference in differences, the municipalities that accounted for the LIRAa presented a significant decrease in the rate of Dengue incidence of approximately 144 cases in a universe of 100,000 inhabitants during the period (b3 = -143.73; IC95% -320.51 – 13.12). For the Event Study, the results behaved similarly, with a result of 274 cases in average (j9 = -274.02; IC95% -430.93 - 117.12). Conclusion: It was concluded that LIRAa in an important tool for monitoring Dengue, since it provides data capable to guide the public policies in a community.
