Análise espacial da incidência da dengue no estado de Sergipe em 2024

Abstract

Dengue is an arboviral disease that has spread worldwide, transmitted by the Aedes aegypti mosquito. Since its initial cases, the disease has posed serious public health challenges in tropical and subtropical countries. Factors such as climate change, urbanization, stagnant water reservoirs, and population growth have contributed to the proliferation of the virus. In 2024, according to the Ministry of Health, Brazil registered approximately 4.7 million probable cases of dengue between January 01 and May 16. In Sergipe, the state’s contingency plan recorded 432 cases by April 6. Given this context, the objective of this study was to examine the spatial distribution of confirmed dengue cases in the State of Sergipe from January 1 to June 7, 2024. According to the analyzed data, 990 individuals were diagnosed with dengue during this period. The three municipalities with the highest incidence rates were: Lagarto, with 304.22 cases per 100,000 inhabitants; Feira Nova, with 267.05 cases per 100,000 inhabitants; and Divina Pastora, with 151.23 cases per 100,000 inhabitants. Brejo Grande, Cristinápolis, Frei Paulo, Ilha das Flores, Macambira, Nossa Senhora de Lourdes, Pedra Mole, Pedrinhas, Santo Amaro das Brotas, and Telha reported no cases of dengue. The uneven distribution of incidence among the municipalities, evidenced by maps and spatial autocorrelation indices, underscores the need for targeted interventions in the most affected areas.
