本文描述了巴西米纳斯吉拉斯州贝洛奥里藏特大都市区发生的17例急性血吸虫病病例。所有受影响的人都在度假村的游泳池里洗澡，泳池里的水来自附近的一条小溪。表面上干净的水和没有蜗牛的池塘给人错误的印象，认为没有感染的风险。在对该物种的现场进行疟疾学调查期间，发现了光滑生物螺，并对曼氏血吸虫检测呈阳性。所有患者都住在贝洛奥里藏特大都市区巴雷罗的中产阶级地区，受过中等程度的学校教育。确定正确诊断的困难表现为在17个不同的医疗机构寻求医疗护理、广泛的实验室测试和不适当的治疗管理。在所有被研究的群体中，都发现缺乏对这种疾病的了解。流行地区蓬勃发展的乡村旅游被认为是感染的一个可能的危险因素，特别是对于城市中心非免疫的中上层社会的个人。对疾病控制和预防这一复杂问题的多学科方法给予了特别关注。
The present article describes the occurrence of 17 cases of acute schistosomiasis in the metropolitan area of Belo Horizonte, state of Minas Gerais, Brazil. All individuals affected took a bath in a swimming pool of a holiday resort that was provided with water from a nearby brook. The apparently clean water and the absence of snails in the pool gave the wrong impression that there was no risk for infection. During a malacological survey at the site snails of the species Biomphalaria glabrata were found and tested positive for Schistosoma mansoni. All the patients live in the middle-class area of Barreiro, metropolitan area of Belo Horizonte and have medium grade school education. The difficulties in establishing the right diagnosis is expressed by the search for medical attention in 17 different medical facilities, the wide range of laboratory test and the inadequate treatment administration. A lack of knowledge about the disease was found in all groups studied. The booming rural tourism in endemic areas is identified as a probable risk factor for infection, especially for individuals of the non-immune middle and upper class parts of the society in urban centers. Special attention is given to a multidisciplinary approach to the complex issue of disease control and prevention.
