Colombia recorded 11 cases of acute Chagas disease and 80 cases of oral contamination with Trypanosoma cruzi. The current study analyzes the entomological and parasitological characteristics of the outbreak in Aguachica, Cesar Department, in 2010. An interdisciplinary group of health professionals and regional university personnel conducted the laboratory tests in the patients and the investigation of the transmission focus. Eleven cases of acute Chagas diseases were detected in a single family in a dwelling with domiciliated triatomines and Rhodnius pallescens, Pantrongylus geniculatus, Eratyrus cuspidatus, and two Didelphis marsupialis opossums infected with T. cruzi in Attalea butyracea and Elaeis oleifera palm trees in the urban area of Aguachica. The study analyzes the role of R. pallescens and palm trees in the wild cycle of T. cruzi and in oral transmission of Chagas disease. Sporadic incursions by wild R. pallescens, P. geniculatus, and E. cuspidatus from the nearby palm trees into human dwellings may cause increasingly frequent outbreaks of oral Chagas disease.
哥伦比亚记录了11例急性恰加斯病病例和80例克氏锥虫口腔感染病例。本研究分析了2010年在塞萨尔省阿瓜奇卡爆发疫情的昆虫学和寄生虫学特征。一个由卫生专业人员和地区大学人员组成的跨学科小组对患者进行了实验室检测，并对传播源进行了调查。在阿瓜奇卡市区一户人家中发现了11例急性恰加斯病病例，该住所内有栖息的锥蝽以及苍白罗得锥蝽、膝形潘氏锥蝽、尖吻埃氏锥蝽，还有两只在油棕和油椰棕榈树上感染了克氏锥虫的南美袋鼬负鼠。该研究分析了苍白罗得锥蝽和棕榈树在克氏锥虫野外循环以及恰加斯病口腔传播中的作用。野生的苍白罗得锥蝽、膝形潘氏锥蝽和尖吻埃氏锥蝽从附近棕榈树偶尔侵入人类住所，可能导致口腔恰加斯病疫情愈发频繁地爆发。
