| Popis: | The study objective was to investigate an acute case of Chagas disease in the San Pedro de Shishita community, Pebas District, in the Peruvian Amazon basin, a non-endemic area. Both parents of the index case (acute case) were thoroughly interviewed, a seroepidemiological survey was carried out in the community, parasitological exams were carried out only in relatives of the index case, and triatomine bugs were searched for inside houses, peridomiciliary, and in wild environments. Seroprevalence for IgG anti-T. cruzi antibodies was 1/104 (0.96%), using an ELISA test and an indirect immunofluorescence assay. Panstrongylus geniculatus and Rhodnius pictipes adults were found. The index case is autochthonous from San Pedro de Shishita, but the source of transmission is unknown. O objetivo deste trabalho foi estudar caso da doença de Chagas aguda na comunidade indígena de San Pedro de Shishita, sem conhecimento da origem da transmissão. San Pedro de Shishita, distrito Pebas, região da Amazônia peruana é uma área não endêmica. Foram entrevistados os pais do paciente e feito inquérito soroepidemiológico dos participantes e estudos parasitológicos da família e procurou-se também triatomíneos no ambiente doméstico, peridomiciliar e silvestre. A soroprevalência de anticorpos IgG anti-T. cruzi foi 1/ 104 (0,96%) por ELISA e imunofluorescência indireta. Foram encontrados adultos de Panstrongylus geniculatus e Rhodnius pictipes |
