Resumo: | Triatomine infestation, prevalence of T. cruzi antibodies in humans and domestic animals, and variables potentially associated with the presence of triatomines in a rural domiciliary unit (DU) were investigated in nine municipalities and one district of Paraná, Brazil, from June 1996 to February 2000. DUs were defined as all houses and annexes on a given piece of property. Blood samples from human volunteers, dogs, and cats were submitted to indirect immunofluorescence. An epidemiological form was completed for each DU. A logistic model was adopted in order to identify associations. Seven out of nine municipalities were positive for triatomines. T. infestans was not captured, but T. sordida, P. megistus, and R. neglectus were. Different variables were considered decisive for the presence of triatomines across the municipalities: proximity to residual wooded areas, i.e. either scrub forest (capoeira) or islands of residual forest (slightly dense vegetation), longer time of residence, existence of inhabited houses, and past DU infestation. In order to ensure proper continuation of the recommended Chagas disease control program, entomo-epidemiological surveillance measures need to be maintained. |

Uma UD foi definida como todas as casas e anexos existentes na propriedade. Amostras de sangue de voluntários humanos, cachorros e gatos foram submetidos à imunoflorescência indireta. Uma ficha epidemiológica foi preenchida para cada UD pesquisada. Foi adotado um modelo logístico para identificar associações. Sete dos nove municípios foram positivos para triatomíneos. T. infestans não foi capturado. T. sordida, P. megistuse R. neglectusforam as espécies capturadas. Diferentes variáveis foram consideradas decisivas para a presença de triatomíneos nos municípios: proximidade à mata residual-capoeira ou ilhas de mata densa, maior tempo de residência, existência de casas habitadas e UD infestada no passado. A fim de assegurar a continuidade do controle da doença de Chagas, medidas de vigilância entomo-epidemiológicas devem ser mantidas nesses municípios.Reports in Public HealthCadernos de Saúde Pública2004-10-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersiontext/htmlapplication/pdfhttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/2366Reports in Public Health; Vol. 20 No. 5 (2004): September/OctoberCadernos de Saúde Pública; v. 20 n. 5 (2004): Setembro/Outubro1678-44640102-311Xreponame:Cadernos de Saúde Públicainstname:Fundação Oswaldo Cruz (FIOCRUZ)instacron:FIOCRUZenghttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/2366/4732https://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/2366/4733Falavigna-Guilherme, Ana LuciaSantana, RosângelaPavanelli, Gilberto CezarLorosa, Elias SeixasAraújo, Silvana Marques deinfo:eu-repo/semantics/openAccess2024-03-06T15:26:59Zoai:ojs.teste-cadernos.ensp.fiocruz.br:article/2366Revistahttps://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:2024-03-06T13:02:46.750162Cadernos de Saúde Pública - Fundação Oswaldo Cruz (FIOCRUZ)true |
