Although cystic echinococcosis (CE) is an important public health problem in Rio Negro Province, current epidemiological data for CE, in this region of Argentina, are not available. Therefore, a community-based study, which incorporated diagnostic imaging and a questionnaire, was conducted in Ingeniero Jacobacci, a small town in southern Rio Negro Province. This study sought to assess the prevalence of human CE, in the study population, and to evaluate epidemiologic factors associated with CE transmission within the study area. Of the 560 individuals who volunteered to participate in the study, 189 (34%) were children and 371 (66%) were adults. All study participants were screened for CE using abdominal ultrasound scanning, with CE-positive or suspect individuals also receiving thoracic radiographs. The overall prevalence of CE was 7.1% (40/560), with 1.6% (3/189) of children, and 10% (37/371) of adults diagnosed as CE-positive. Although 92.5% (37/40) of the CE-positive individuals had only hepatic lesions, two participants had both hepatic and pulmonary lesions, and one participant had a single renal lesion. Approximately 92% (340/371) of the adult study participants completed the questionnaire, which was used to identify factors associated with an increased risk for human infection. Age, level of education, dog ownership, and contact with sheep were found to be significantly associated with CE status. This study demonstrated that CE continues to be highly endemic in this region of Rio Negro Province, Argentina. In addition, community-based ultrasound screening surveys are a noninvasive, effective approach to case detection at the community level.
尽管囊性棘球蚴病（CE）是里奥内格罗省一个重要的公共卫生问题，但在阿根廷这个地区，目前尚无CE的流行病学数据。因此，在里奥内格罗省南部的一个小镇因赫涅罗·雅各布acci开展了一项基于社区的研究，该研究纳入了诊断成像和问卷调查。本研究旨在评估研究人群中人类CE的患病率，并评估研究区域内与CE传播相关的流行病学因素。在自愿参与研究的560人中，189人（34%）为儿童，371人（66%）为成年人。所有研究参与者均通过腹部超声扫描筛查CE，CE阳性或疑似个体还接受了胸部X光检查。CE的总体患病率为7.1%（40/560），其中1.6%（3/189）的儿童和10%（37/371）的成年人被诊断为CE阳性。尽管92.5%（37/40）的CE阳性个体仅有肝脏病变，但有两名参与者同时有肝脏和肺部病变，一名参与者有单个肾脏病变。约92%（340/371）的成年研究参与者完成了问卷，该问卷用于确定与人类感染风险增加相关的因素。年龄、教育程度、养狗情况和与羊的接触被发现与CE状况显著相关。本研究表明，在阿根廷里奥内格罗省的这个地区，CE仍然高度流行。此外，基于社区的超声筛查调查是在社区层面进行病例检测的一种无创、有效的方法。
