Abstract
Objective: Investigate the epidemiological patterns of dengue in Brazil between 2014 and 2023, analyzing determining factors, surveillance and vector control strategies, the impact of climate change, and socioeconomic implications, with the purpose of contributing to improve policies for prevention and clinical management of the disease. Methods: Descriptive, retrospective, and cross-sectional epidemiological study using data from the DATASUS, and IBGE between 2014 and 2023. Notified cases and deaths due to dengue in the five Brazilian macro-regions were analyzed. Descriptive statistics were applied, and the data were organized in Microsoft Excel®. Results: Between 2014 and 2023, 10,125,185 cases of dengue were reported in Brazil. The years 2015, 2019, 2016, 2022, and 2023 recorded the highest numbers of cases. The Southeast region was the most affected, with São Paulo, Minas Gerais, and Goiás standing out. There was a significant increase in laboratory-confirmed cases, with a predominance of the DENV1 serotype in 2023. Conclusion: The study reveals an alarming growth in the dengue burden, emphasizing the need for effective control strategies. The overlap with COVID-19 and the resurgence of serotypes reinforce the importance of continuous surveillance and comprehensive public health approaches to face this growing challenge.
