Background and Objectives: Describe the epidemiology of Acute Chagas Disease (ACD) in Brazil through sociodemographic and clinical variables between 2007 and 2022. Methods: Epidemiological study using secondary data from SINAN/DATASUS, covering the period from 2007 to 2022. The variables included were outcome, confirmation criterion, age group, probable place of infection, region of residence, year/month/region of notification, sex, education level, probable mode of infection, race, pregnancy status, and Federative Unit (state) of residence. Population estimates were obtained from DATASUS. Results: There were 4,019 cases of Acute Chagas Disease (ACD), of which 3,791 were confirmed by laboratory tests, and the national prevalence was 0.124 per 100,000 population. The North and Northeast regions accounted for 98.28% of the cases. Most cases occurred in males, and the most affected age group was 20–39 years. In the North and Northeast, oral transmission was the most common mode of infection. Regarding race, most cases occurred in individuals identified as mixed-race (pardo). In 3,134 cases, the home was the probable place of infection.The period with the highest number of reported cases was between the months of August and December, as well as in the years 2018, 2019, and 2022. Infection during pregnancy was reported in all trimesters. Most patients survived.Conclusion: ACD continues to be a serious public health concern, mainly because of its chronic phase, during which patients experience most of the fatal complications.
