Resumo: | The aim of this article was to confirm and describe an outbreak of acute Chagas disease involving oral transmission in the western region of Rio Grande do Norte State, Brazil. This was a descriptive case series study in which the data sources were medical records and interviews with suspected cases from September 16 to November 19, 2015. An entomological investigation was conducted in the probable sites of infection for acute Chagas disease cases. Eighteen cases of acute Chagas disease were confirmed in residents of four municipalities (counties) in Rio Grande do Norte State. The most frequently reported signs and symptoms were fever and weakness (n = 18), followed by myalgia (n = 17), prostration, loss of appetite, and edema of the lower limbs (n = 15). Median duration of fever was 20 days (range: 6 to 45 days). Fifteen cases were confirmed by the laboratory criterion and three by epidemiological link with consistent clinical characteristics. All confirmed cases reported having consumed sugar cane juice from the same mill. A total of 110 triatomines were captured on the plantation where the sugar cane had been crushed for juice. The insects were found in the peridomicile, in stacks of firewood and close to the sugar cane mill. The majority of the captured specimens were Triatoma brasiliensis and showed a natural infection rate of 63%. The Chagas disease outbreak was confirmed with oral transmission via ingestion of sugar cane juice contaminated with infected triatomines, as evidenced by the epidemiological link between the investigated cases and the entomological survey in the probable site where the infection occurred. |

Se trata de un estudio descriptivo del tipo serie de casos, contando como fuente de datos los registros de atención médica y entrevistas en los casos sospechosos entre el 16 de septiembre y el 19 de noviembre de 2015. Se realizó una investigación entomológica en las probables localidades de infección de los casos de enfermedad de Chagas aguda. Fueron confirmados 18 casos de enfermedad de Chagas aguda en residentes de cuatro municipios de Rio Grande do Norte. Los signos y síntomas más informados fueron fiebre y debilidad (n = 18), seguidos de mialgia (n = 17), postración, inapetencia y edema de miembros inferiores (n = 15). La media de duración de la fiebre fue de 20 días (intervalo: 6 a 45 días). Quince casos fueron confirmados por criterio de laboratorio y tres por vínculo epidemiológico con clínica compatible. Todos los casos confirmados informaron haber consumido caldo de caña de la misma procedencia. Fueron capturados 110 triatominos en la hacienda donde se produjo la molienda de la caña consumida. Los insectos estaban en el peridomicilio, en montones de leña y cerca del ingenio azucarero. La mayoría de los ejemplares capturados era de la especie Triatoma brasiliensis, y presentó un índice de infección natural de un 63%. Se confirmó un brote de la enfermedad de Chagas de transmisión oral por ingestión de caldo de caña contaminado por triatomino infectado, evidenciado por el vínculo epidemiológico entre los casos investigados y la investigación entomológica en el lugar probable de infección.O objetivo do artigo foi confirmar e descrever um surto da doença de Chagas aguda por transmissão oral na mesorregião Oeste Potiguar, Rio Grande do Norte, Brasil. Trata-se de um estudo descritivo do tipo série de casos, tendo como fonte de dados os registros de atendimentos médicos e entrevistas com os casos suspeitos entre 16 de setembro e 19 de novembro de 2015. Realizou-se pesquisa entomológica nas prováveis localidades de infecção dos casos de doença de Chagas aguda. Foram confirmados 18 casos de doença de Chagas aguda em residentes de quatro municípios do Rio Grande do Norte. Os sinais e sintomas mais relatados foram febre e fraqueza (n = 18), seguidos de mialgia (n = 17), prostração, inapetência e edema de membros inferiores (n = 15). A mediana de duração da febre foi de 20 dias (intervalo: 6 a 45 dias). Quinze casos foram confirmados por critério laboratorial e três por vínculo epidemiológico com clínica compatível. Todos os casos confirmados relataram ter consumido caldo de cana da mesma procedência. Foram capturados 110 triatomíneos na fazenda onde ocorreu a moagem da cana consumida. Os insetos estavam no peridomicílio, em amontoados de lenha e próximos ao engenho. A maioria dos exemplares capturados era da espécie Triatoma brasiliensis, e apresentou um índice de infecção natural de 63%. Foi confirmado surto da doença de Chagas de transmissão oral por ingestão de caldo de cana contaminado por triatomíneo infectado, evidenciado pelo vínculo epidemiológico entre os casos investigados e a pesquisa entomológica no local provável de infecção.Reports in Public HealthCadernos de Saúde Pública2018-02-05info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersiontext/htmlapplication/pdfhttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/6715Reports in Public Health; Vol. 34 No. 1 (2018): JanuaryCadernos de Saúde Pública; v. 34 n. 1 (2018): Janeiro1678-44640102-311Xreponame:Cadernos de Saúde Públicainstname:Fundação Oswaldo Cruz (FIOCRUZ)instacron:FIOCRUZporhttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/6715/14478https://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/6715/14479Alexander VargasJuliane Maria Alves Siqueira MaltaVeruska Maia da CostaLeandro Del Grande CláudioRenato Vieira AlvesGilmar da Silva CordeiroLúcia Maria Abrantes AguiarJadher Percioinfo:eu-repo/semantics/openAccess2024-03-06T15:29:30Zoai:ojs.teste-cadernos.ensp.fiocruz.br:article/6715Revistahttps://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:2024-03-06T13:07:40.904184Cadernos de Saúde Pública - Fundação Oswaldo Cruz (FIOCRUZ)true |
