Resumo: The seroprevalence of Chagas disease in humans and the presence of triatomines were investigated in a rural locality in the State of Ceará, Brazil, an historically endemic region. Approximately 80% of the surveyed residents agreed to undergo serological tests. Intradomestic and peridomestic environments were searched for triatomines in both the dry and rainy seasons. The prevalence rate of Chagas disease was 1.2% and the majority of individuals confirmed with the disease over 50 years of age. A total of 761 specimens of triatomines were captured, most of which were from colonies composed of nymphs and adult bugs, and the majority of specimens were obtained in the dry season. Triatoma brasiliensis was the predominant species. Analysis using light microscopy revealed that 28.6% of the insects were Trypanosoma cruzi positive. Results suggest that peridomestic man-made structures, such as animal shelters, improper storage of timber and uninhabited dwellings contribute to the high rate of triatomine infestation in the area.

Se informó sobre la presencia de insectos en los hogares durante los períodos de sequía y lluvia. La seroprevalencia en el período fue un 1,2%, mayor entre las personas de más de 50 años de edad, y no hubo diferencias significativas en relación al sexo. Se capturaron 761 ejemplares de insectos en colonias compuestas por ninfas y adultos de insectos, principalmente, Triatoma brasiliensis, especialmente durante la estación seca. El examen del contenido intestinal de los insectos reveló que un 28,6% eran T. cruzi positivo. Los resultados sugieren que los refugios de animales y el almacenamiento inadecuado de materiales fuera del hogar, especialmente pilas de madera y casas deshabitadas, contribuyen a la alta tasa de infestación de insectos en la localidad.A presença de triatomíneos e a soroprevalência da infecção chagásica humana foram investigadas em uma localidade rural do Estado do Ceará, Brasil, região endêmica histórica da doença de Chagas. Os triatomíneos foram pesquisados nos domicílios, nos períodos de seca e de chuva. A soroprevalência encontrada no período foi de 1,2%, maior entre pessoas com mais de 50 anos de idade, e sem diferença significativa em relação ao sexo. Foram capturados 761 espécimes de triatomíneos, em colônias compostas de ninfas e insetos adultos, com predominância de Triatoma brasiliensis, especialmente no período de seca. O exame do conteúdo intestinal dos insetos revelou que 28,6% eram Trypanosoma cruzi positivos. Os resultados sugerem que os abrigos de animais e armazenamento inadequado de materiais no peridomicílio, particularmente amontoados de madeiras, bem como moradias desabitadas, contribuem para o alto índice de infestação de triatomíneos na localidade.Reports in Public HealthCadernos de Saúde Pública2014-04-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersiontext/htmlapplication/pdfhttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/5398Reports in Public Health; Vol. 30 No. 4 (2014): AprilCadernos de Saúde Pública; v. 30 n. 4 (2014): Abril1678-44640102-311Xreponame:Cadernos de Saúde Públicainstname:Fundação Oswaldo Cruz (FIOCRUZ)instacron:FIOCRUZenghttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/5398/11100https://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/5398/11101Carolina Fausto de Souza CoutinhoReinaldo Souza-SantosNatalia Faria Daflon TeixeiraIngebourg GeorgTaís Ferreira GomesMarcio Neves BoiaNeilane Bertoni dos ReisAlexander de Oliveira MaiaMarli Maria Limainfo:eu-repo/semantics/openAccess2024-03-06T15:28:41Zoai:ojs.teste-cadernos.ensp.fiocruz.br:article/5398Revistahttps://cadernos.ensp.fiocruz.br/ojs/index.php/csphttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/oaicadernos@ensp.fiocruz.br||cadernos@ensp.fiocruz.br1678-44640102-311Xopendoar:2024-03-06T13:06:12.548664Cadernos de Saúde Pública - Fundação Oswaldo Cruz (FIOCRUZ)true
