本文根据不同发展程度的都市化地区住房卫生设施和供水状况评估了巴西巴拉坎比市沙布谷地区曼氏血吸虫感染和重度感染的风险性。 沙布谷是巴西东南部巴拉坎比市的一个村,Sabuguinho河流经该地,当地气候湿热,为浅栖双脐螺孳生地。曼氏血吸虫感染率为2.9％,其中重度感染率43.7％,EPG几何平均值为79。70年代起巴拉坎比市开始实行都市化,现已形成“农村—都市”式的环境。95％以上(311户)住户都有简陋的厕所,77％有
In this paper, we evaluated the risk of Schistosoma mansoni infection and severe infection in Sabu Valley, Balambambi, Brazil, according to the level of urbanization and sanitation and water supply in urban areas. Shabu Valley is a village in the town of Barabamba, southeastern Brazil, through which the Sabuguinho River flows. The local climate is hot and humid, producing shallow shallow snails. The infection rate of Schistosoma mansoni was 2.9%, of which 43.7% were severe infections and the average geometric mean of EPG was 79. The city of Barabamba began to be urbanized in the 1970s and a “rural-urban” environment has been formed. More than 95% (311 households) of households have shabby toilets, 77% have
