Abstract
Dengue is the most impactful arboviral disease worldwide, with approximately 2.5 billion people at risk of infection. Transmitted primarily by Aedes aegypti, its spread is favored by uncontrolled urban growth, inadequate sanitation, and socio-environmental conditions that enhance vector proliferation. Additionally, deforestation and wildfires alter ecosystems and microclimates, creating environments that may increase mosquito breeding sites and influence the disease’s transmission dynamics. The Brazilian regions served as the study area, where an epidemiological investigation was conducted using population aggregates as the unit of analysis and secondary data from the National Health Information System (SNIS) for the period between 2000 and 2013. This study aimed to generate relevant information to better understand dengue dynamics and its relationship with the recurring issue of wildfires. The states that showed significant correlation were Rondônia, Roraima, Pará, Amapá, Alagoas, Bahia, Espírito Santo, Rio Grande do Sul, Paraná, and São Paulo. In all these locations, a positive correlation was observed between wildfire indicators and dengue morbidity, except for São Paulo and Paraná, which showed the opposite tendency, with a negative correlation. Therefore, understanding how urban and environmental factors, including deforestation and wildfires, affect vector proliferation is essential for guiding effective dengue control strategies.
