INTRODUCTION: Chagas disease (CD) is a disease caused by the protozoan flagellates of the Kinetoplastid order Trypanosoma cruzi. Approximately 8,000,000 people are infected worldwide, mainly in Latin America, causing disabilities and more than 10,000 deaths per year OBJECTIVE: This study aimed to describe the epidemiological panorama of CD in the Western Brazilian Amazon from 2007 to 2018. METHODS: In this ecological study, secondary data regarding the confirmed cases of T. cruzi infection in the states of Acre, Amazonas, Rondônia, and Roraima were collected from the Single Health System Notification Information System of the Department of Informatics of the Single Health System and were analyzed. The data were used to characterize the epidemiological profile of T. cruzi infection and to determine the frequency of infection in Western Amazonia. RESULTS: A total of 184 cases of CD were reported in Western Amazonia, and the highest number of cases was reported in the states of Amazonas and Acre. CONCLUSION: The epidemiological panorama of the Western Brazilian Amazon from 2007 to 2018 includes a greater number of cases of T. cruzi infection in men aged 20-39 years and those living in rural areas. Oral transmission was prevalent in the region during the study, and the highest number of cases was reported in the months of April and December. Epidemiological data are an important resource for understanding the dynamics of CD and the main aspects related to the health-disease process.
