Situated in the Volta Grande do Xingu region, the Belo Monte Hydroelectric Power Plant has been responsible for extensive deforestation, forest suppression, flooding, watercourse deviations, and wildlife relocation. These alterations contribute to an ecologically unstable environment, potentially leading to increased snake mobility, bringing them closer to residences and causing a rise in snakebite incidents. Objectives: This study aims to understand the clinical-epidemiological profile of snakebite incidents in municipalities directly influenced by the Belo Monte Hydroelectric Power Plant and its impact on the number of cases in the region. Methodology: It is an epidemiological, observational, and analytical study based on secondary data from SINAN, using the number of cases from the municipalities of Altamira, Anapu, Brasil Novo, Senador José Porfírio, and Vitória do Xingu. Contingency G tests, Anova One Way, Kruskal-Wallis, and Chi-square tests were used for variation analysis. In addition, Simple Linear Regression was employed to assess seasonality. Results: The research results revealed a statistically significant increase, with a 41.4% rise in snakebite incidents compared to the pre-construction period of the power plant. Altamira showed the highest rate of increase. Bothrops genus snakes caused the majority of incidents, with Micrurus being the most severe genus. The primary victims were males, aged 20-49, of mixed race, and with low educational attainment, often working in rural areas. Seasonality indicated that incidents occurred more frequently during the rainy months with low temperatures. Conclusion: It was possible to conclude that the environmental impacts caused by the installation of the hydroelectric plant and reservoir filling led to a significant increase in reported cases throughout the study region. The results of this research can be useful in developing strategies for the prevention and management of these incidents, contributing to the scientific knowledge of snakebites in the region and serving as a basis for new studies in the field.Acesso AbertoAcidentes ofídicosUHE Belo MonteVolta Grande do XinguSnakebitesBelo Monte Hydroelectric Power PlantGreat Bend of the XinguCNPQ::CIENCIAS DA SAUDE::SAUDE COLETIVA::EPIDEMIOLOGIATrabalho de Curso - Graduação - MonografiaAttribution-NonCommercial-NoDerivs 3.0 Brazil
