Abstract

This study investigates the association between dengue occurrence and the spatial distribution of vegetation in the urban area of Caldas Novas, Goiás. The purpose is to provide insights into the role of vegetation in dengue transmission in urban environments, contributing to a better understanding of the factors that affect the spread of the disease. Dengue notification data by neighborhood were obtained from the municipal government for the years 2018 to 2022. Vegetation coverage data for the neighborhoods were estimated using a Random Forest classification model. Regression models were fitted to describe the occurrence of the disease as a function of vegetation coverage. The decrease in vegetation exponentially influences the number of notifications. In neighborhoods with more than 75% vegetation coverage, there was no significant variation in notifications over the studied period.
