Mapeamento da dengue: uma análise da distribuição intraurbana em João Pessoa–PB

Abstract

The overall objective of the research was to analyze the distribution of dengue cases in the urban areas of João Pessoa–PB, between 2014 and 2024, with the aim of identifying the intra-urban areas with the highest incidence. To conduct the study, data were collected on the number of reported dengue cases from the Epidemiological Surveillance Management of the Municipal Health Department of João Pessoa, referring to the period from January 2014 to April 2024. Urban data were also used, such as the number of inhabitants per neighborhood and territorial area, obtained from the IBGE (2010) and the Municipal Atlas of João Pessoa – Filipeias (2025), to estimate the variables: dengue incidence per 1,000 inhabitants, population density, and urban concentration. The data were analyzed using descriptive statistics and visually represented in territorial maps. The results indicate a high incidence of dengue in the municipality, with Mangabeira (4,405 cases) and Mussuré (2 cases) presenting, respectively, the highest and the lowest number of notifications in the analyzed period. Furthermore, evidence of seasonal patterns was observed in the concentration of cases throughout the years, months, and neighborhoods. Thus, the spatial and temporal distribution of dengue cases in João Pessoa may be related to socioeconomic factors and urban infrastructure. In this sense, understanding the territorial dynamics of the disease in the municipality can contribute to reflections and offer relevant subsidies for the formulation of more effective public policies in tackling dengue.
