Chagas disease is a zoonosis caused by a hemoflagellate protozoan called Trypanosoma cruzi. We describe the clinical presentation of an acute outbreak of Chagas disease by oral transmission in a group of 3 cousins aged 10, 14, 16 years, with clinical picture of 18 days of fever peaks at 38 °C and moderate epigastric abdominal pain. The maternal grandmother was positive for Chagas disease, with no other history. On physical examination tachycardic, the rest without alteration. Paraclinical findings on admission: elevated CRP and negative thick drop. At 24 hours, positive Trypanosoma cruzi antibody in the 3 patients and positive febrile antigen for Proteus ox-19 1/320 in the youngest. Acute Chagas disease in pediatrics is usually asymptomatic; however, it is evident that it can rapidly progress to chagasic myocarditis and severe thrombocytopenia, increasing considerably the risk of cardiogenic shock, cardiac decompensation, and even death.
