Introduction: Recent environmental changes and failures designed a new epidemiological scenario for some re-emerging infectious disease in Brazil, as example, infections by Trypanosoma cruzi. Frequently described as acute Chagas disease with high morbidity, which is directly assigned to the main form of transmission (oral transmission), but almost invariable involves sylvatic vectors of the parasite with unknown behavior. New epidemiological approaches are necessary to search strategies against this emergent disease that exposes riverian and neglected populations since early ages. Method: Descriptive study applied to surveillance systems to Chagas disease (CD) control in children from riverine areas of Amazon region, Brazil. Results: Children with acute Chagas disease were diagnosed by parasitological and serological tests in Evandro Chagas Institute. Four children with 1 to 8 years-old were treated and had evidences of vectorial-oral transmission. All children had prolonged sick fever and half of them evolved acute myopericarditis with total resolution after treatment. None of the cases was identified during outbreaks. Entomological searches identified sylvatic vectors of T. cruzi (Rhodnius pictipes species) in their house’s periphery. One mother informed us that found her child with an insect squeezed in his mouth two days before the febrile illness. The children were treated and followed for a long time. We didn´t found evidences of evolution to cardiac disease. Conclusion: It is emphasized the necessary accuracy of clinical suspicion and precocious diagnosis of CD in view to eliminate the potential cardiac commitment of children in your adulthood. Insects with an unknown behavior were registered in these cases report. New epidemiological and educational tools to avoid the contact of triatomine vectors of CD and increases food security for people living in forests and riverside of Amazon areas are excellent perspectives to surveillance systems.
