ABSTRACT Background: Chagas disease is gaining importance in the Brazilian Amazon region as a differential diagnosis of febrile syndrome. The most recent microoutbreak occurred in Ipixuna, in Amazonas state. Methods: An epidemiological survey was conducted using parasitological and serological tests, and electrocardiographic analysis. Results: The patients belonged to one family and had ingested açaí acquired from Ipixuna. All patients reported fever and initially a thick blood smear test was done to identify Trypanosoma cruzi. Benznidazole treatment was administered to all patients. Conclusions: Knowledge of the epidemiological dynamics of Chagas disease allows us to improve control and management measures for this disease.
