目的评估微型水坝建设对附近社区疟疾发病率的影响，包括可能增加发病高峰和延长传播时间。设计四个季度的疟疾发病率调查周期，每个周期30天，在靠近大坝的八个高危社区与八个海拔相似但超出蚊子飞行范围的对照村庄进行了研究。受试者约7000名10岁以下的儿童生活在3公里内的村庄的微型水坝和控制村8 - 10公里远。主要结果措施疟疾发病率在这两个社区。结果疟疾的总发病率为那些村庄接近大坝是14.0发作/1000儿童月的风险相比，1.9在控制村。七倍的比例发病率显着较高，在这两个社区在海拔低于1900米。结论有必要注意到健康问题，在实施生态和环境发展计划，特别是适当的疟疾控制措施，以抵消这些大坝附近的风险增加。
Objective To assess the impact of construction of microdams on the incidence of malaria in nearby communities in terms of possibly increasing peak incidence and prolonging transmission.Design Four quarterly cycles of malaria incidence surveys, each taking 30 days, undertaken in eight at risk communities close to dams paired with eight control villages at similar altitudes but beyond flight range of mosquitoes.Setting Tigray region in northern Ethiopia at altitudes of 1800 to 2225 m.Subjects About 7000 children under 10 years living in villages within 3 km of microdams and in control villages 8-10 km distant.Main outcome measures Incidence of malaria in both communities.Results Overall incidence of malaria for the villages close to dams was 14.0 episodes/1000 child months at risk compared with 1.9 in the control villages-a sevenfold ratio. Incidence was significantly higher in both communities at altitudes below 1900 m.Conclusions There is a need for attention to be given to health issues in the implementation of ecological and environmental development programmes, specifically for appropriate malaria control measures to counteract the increased risks near these dams.
