ObjectivesTo evaluate the potential transmission ofSchistosoma mansoni through well water pumped into households in a rural Brazil community within the context of Brazil's rural electricity programme Luz帕拉Todos（Light for All）.MethodsAll households were interviewed about their water facilities and domestic water use，all household members were examined for S. 2001年至2009年期间进行了曼氏菌感染和阳性治疗，以及软体动物和水接触研究。结果2009年Virgem das Graças研究区142户家庭中有31户拥有带电泵的威尔斯井，而2001年没有威尔斯井，储水罐的数量从85个增加到131个。通过管道井水的血吸虫病传播的可能性是由双脐螺gabrata，包括S。曼氏感染的蜗牛，从威尔斯，存在的Biomphalariin坦克和S.曼氏尾蚴在流动的水中保持相当长的距离的感染性。然而，获得井水与较高的S无关。结论我们的研究结果表明，需要进一步的研究，以确定井水的传染性和血吸虫病传播的影响。
ObjectivesTo evaluate the potential transmission ofSchistosoma mansonithrough well water pumped into households in a rural Brazilian community within the context of Brazil’s rural electrification programLuz Para Todos(Light for All).MethodsAll households were interviewed about their water facilities and domestic water use, all household members were examined forS. mansoniinfections and positives treated, and malacological and water contact studies were performed between 2001 and 2009.ResultsThirty‐one of the 142 households in the Virgem das Graças study area owned wells with electric pumps in 2009, vs. no wells in 2001, and the number of water storage tanks increased from 85 to 131. The potential for schistosomiasis transmission through piped well water was indicated by the recovery ofBiomphalaria gabrata, includingS. mansoni‐infected snails, from wells, the presence ofBiomphalariain tanks and the ability ofS. mansonicercariae to remain infective for considerable distances in flowing water. However, access to well water was not associated with higherS. mansoniinfection rates.ConclusionsOur results indicate that further studies are needed to determine the infectivity of well water and its impact on schistosomiasis transmission.
