Recent biosurveillance findings at Joint Base San Antonio (JBSA), a large military installation located in south-central Texas, indicate the potential for vector-borne human Chagas disease. A cross-sectional study was conducted to determine the prevalence and seroprevalence of infection in highest risk subpopulations on the installation, including students and instructors who work and sleep in triatomine-endemic field settings. Real-time polymerase chain reaction, enzyme-linked immunosorbent assay, and indirect immunofluorescent antibody assay were performed on enrolled subjects ( = 1,033), none of whom tested positive for or anti- antibodies. Current countermeasures used during field training on JBSA appear to be sufficient for preventing autochthonous human Chagas disease.
位于得克萨斯州中南部的大型军事基地圣安东尼奥联合基地(JBSA)最近的生物监测结果表明,存在通过病媒传播人类恰加斯病的可能性。开展了一项横断面研究,以确定该军事基地中高危亚人群(包括在锥蝽流行的野外环境中工作和睡眠的学生及教员)的感染率和血清阳性率。对纳入的受试者(n = 1033)进行了实时聚合酶链反应、酶联免疫吸附测定和间接免疫荧光抗体测定,结果显示这些受试者中没有一人检测出克氏锥虫或抗克氏锥虫抗体呈阳性。JBSA野外训练期间目前采取的应对措施似乎足以预防本地人类恰加斯病。
