Introduction: Currently, dengue has an important impact on the well-being of patients and the economy of the public health system. In this sense, the need to carry out epidemiological studies is highlighted in order to assist in the analysis of the state's reality. Objective: To characterize the epidemiological profile of dengue in Minas Gerais, from 2009 to 2019. Material and Methods: Observational descriptive and quantitative study based on data on notifications and admissions obtained from the Notifiable Diseases Information System and the Hospital Information System, from TABNET. Rates of lethality, incidence and hospitalization were calculated using demographic data from the information technology department of the Unified Health System to calculate incidence and hospitalization. The study variables were: the year of occurrence, macro-region of residence, age group, evolution and clinical classification of the disease, gender, education and race. Results: Dengue has a cyclical nature of incidence, and lethality and hospitalization rates fluctuate annually. The Central, Southern Triangle, Northwest, West, Northern Triangle and Vale do Aço macro-regions had high incidence rates, and the Eastern macro-region had the highest hospitalization rate. Most dengue cases were classified as 'classic dengue', and the classification 'severe dengue' had the lowest incidence. Regarding the age group, the 15 to 39-year age group had a higher incidence rate and lower mortality and hospitalization rates, when compared to the elderly population. Furthermore, the evolution to death occurred more frequently in illiterate individuals. Conclusion: The findings of this study elucidate the epidemiological profile of dengue in Minas Gerais, which is characterized by presenting a cyclical national pattern of cases, manifesting itself mainly in a mild form, but with an increase in morbidity and mortality in illiterate and elderly people.
