About Paper:

This project examines how environmental change shapes the spread of dengue in Brazil. As a climate- sensitive, vector-borne disease, dengue transmission is influenced by temperature, rainfall, and urbanization, which affect mosquito breeding conditions, seasonal transmission cycles, and human exposure. Brazil provides a critical case study due to its high dengue burden, rapid urbanization, and climate variability, as well as the disease's expansion into new regions. This project investigates how climate and urbanization are driving the spatial and temporal expansion of dengue in Brazil. Using GIS-based spatial and temporal analysis, this research maps dengue incidence alongside environmental variables, including temperature and precipitation, to identify how changing conditions correspond with disease risk. It also examines regional and seasonal differences to understand where and when environmental factors most strongly influence transmission, including how rainfall variability and temperature shifts shape mosquito dynamics. 310 UNIVERSITY OF OREGON • 2026 UNDERGRADUATE RESEARCH SYMPOSIUM TABLE OF CONTENTS More broadly, this work addresses a key gap in disease models, which often only partially incorporate environmental drivers or fail to fully integrate them with human transmission patterns. Using a One Health framework, this project connects environmental conditions, vector dynamics, and human systems to better capture disease risk and improve early warning systems and prevention strategies in regions increasingly vulnerable to climate-driven disease.
