Building infestation index for Aedes aegypti and occurrence of dengue fever in the municipality of Foz do Iguaçu, Paraná, Brazil, from 2001 to 2016

Abstract

Introduction: the Building Infestation Index (BII) uses the Rapid Assay of the Larval Index for Aedes aegypti (LIRAa) to express the relationship between positive and surveyed properties. We evaluated LIRAa and the relationship between the BII and climate variables for dengue cases in Foz do Iguaçu municipality, Paraná. Methods: Spearman’s correlations for mean precipitation, mean temperature, BII, and dengue cases (time lag). Results: positive correlations between BII and cases, and mean temperature and cases at two months. Weak correlation between precipitation and cases at three months. Conclusions: LIRAa and climate variables correlate with dengue cases.
