Dengue in brazil and colombia: A study of knowledge, attitudes, and practices

Abstract

Introduction: This study was conducted in Brazil and Colombia, where dengue is endemic and vector control programs use chemical insecticides. Methods: We identified knowledge, attitudes, and practices about dengue and determined the infestation levels of Aedes aegypti in one Brazilian and four Colombian communities. Results: The surveys show knowledge of the vector, but little knowledge about diagnosis, prognosis, and treatment. Vector infestation indices show Brazil to have good relative control, while Colombia presents a high transmission risk. Conclusions: Given the multidimensionality of dengue control, vertical control strategies are inadequate because they deny contextualized methods, alternative solutions, and local empowerment.
