A clinical-epidemiologic study of schistosomiasis mansoni was conducted in the population of Ponte do Pasmado, a village in the municipality of Itinga, state of Minas Gerais, Brazil. Faecal parasitology by the Kato-Katz method and clinical examination were performed in 93.8% and 82.8% of the local population, respectively. A socioeconomic survey was also made and the signs and symptoms presented by the patients were recorded, as well as their contacts with natural waters. The rate of Schistosoma mansoni infection was 50.3%; the peak of infection occurred during the second decade of life; there was a predominance of low egg counts in faeces (85.89% of positive patients eliminated less than 500 eggs per gram of faeces); the splenomegaly rate was 1.23%. When the risk factors for S. mansoni infection were studied, significant risks were detected in activities such as fetching water, washing dishes, bathing, and crossing streams.
在巴西米纳斯吉拉斯州伊廷加市的一个村庄——庞特杜斯帕马多村的人群中开展了一项曼氏血吸虫病的临床流行病学研究。分别对当地93.8%的人口采用加藤厚涂片法进行粪便寄生虫学检查，对82.8%的人口进行临床检查。还开展了一项社会经济调查，记录患者出现的体征和症状以及他们与天然水体的接触情况。曼氏血吸虫感染率为50.3%；感染高峰出现在第二个十年；粪便中虫卵计数低的情况占主导（85.89%的阳性患者每克粪便排出的虫卵少于500个）；脾肿大率为1.23%。在研究曼氏血吸虫感染的危险因素时，发现在取水、洗碗、洗澡和过河等活动中存在显著风险。
