在米纳斯吉拉斯[巴西]的图帕雷斯进行了一项基于人群的曼氏血吸虫病临床流行病学研究。对患者进行症状、饮水量、既往史及脾、肝肿大检查。在普查登记的830人中，777人（93.6%）接受了粪便检查（Kato-Katz法），696人（83.8%）接受了临床评价。曼氏血吸虫感染总指数为43.2%。在年轻年龄组（2-14岁）中，从职业、居住时间和接触水的频率方面可以发现感染风险显著增加。血便在阳性者中明显更普遍，而腹泻在阴性者中明显更普遍。该地区的发病率较低，感染强度也较低，以沙门氏菌的数量来衡量。每克粪便中含有曼氏菌卵。接水方式与年龄流行曲线有密切关系。它强调了生活习惯在确定流行率方面的重要性，并指出该地区的曼氏血吸虫病表现为轻微的、某种程度上无害的感染，对整个人口几乎没有影响。
A population based clinical epidemiologic study on schistosomiasis mansoni was carried out in Tuparece, Minas Gerais [Brazil]. The patients were interviewed for symptoms, water contract, past history and examined for spleen and liver enlargement. From the 830 people registered in the census, 777 (93.6%) had their stools examined (Kato-Katz method) and 696 (83.8%) were clinically evaluated. The overall index of Schistomosma mansonii infection was 43.2%. Significant and increased infection risks could be detected in the young age group (2-14 years old) regarding occupation, time of residence of the area and frequency of water contact. Bloody stools were significantly more prevalent among positives, while diarrhea was significantly more prevalent among those negative. The area was shown to have a low morbidity as well as a low intensity of infection measured by the number of S. mansoni eggs per gram of feces. A close correlation was found between water contact pattern and the age prevalence curve. It has emphasized the importance of habits in determining prevalence rates, besides suggesting that schistosomiasis mansoni in the area is manifested as a light and somewhat harmless infection with little consequence for the population as a whole.
