Abstract

Dengue fever remains one of the most significant public health challenges in Brazil, particularly in tropical regions such as the Amazon, caused by the proliferation of the Aedes aegypti mosquito. This study aims to outline the epidemiological profile of dengue in the municipality of Belém, Pará, over a 10-year period (2014–2024), focusing on identifying the most affected demographic groups and analyzing temporal trends. The research is based on secondary data obtained from DATASUS, Brazil’s national public health database.

Methodology:
Data were collected regarding dengue incidence by age group, educational level, income, race/ethnicity, and predominant viral serotype. The dataset was analyzed using descriptive statistics and temporal comparisons, with visual tools applied to highlight patterns and seasonal variations.

Preliminary Results:

The highest incidence of dengue was observed among individuals aged 20 to 59, followed by adolescents between 15 and 19 years old. Most cases were reported among people with incomplete secondary education and monthly income up to two minimum wages. Regarding race/ethnicity, a higher occurrence was found among people identified as "branco" (mixed race), reflecting the city's demographic composition. Serotype analysis revealed DENV-1. A marked increase in case numbers was recorded during the Amazonian winter (rainy season), particularly between January and April.

Conclusion:
The findings indicate a rising trend in dengue cases in Belém, especially during the rainy season, when stagnant water facilitates the proliferation of the Aedes aegypti mosquito. The persistence of transmission and the circulation of multiple serotypes underscore the need for continuous surveillance and tailored prevention strategies, especially targeting the most socioeconomically vulnerable groups.
