We assessed risk factors for vectors of dengue and chikungunya viruses near a new hydroelectric project, Nam Theun 2, in Laos. Immature stages of Aedes aegypti were found only in sites within 40 km of the urban provincial capital, but Aedes albopictus was found throughout. Aedes aegypti pupae were most common in water storage jars (odds ratio [OR] = 4.72) and tires (OR = 2.99), and Ae. albopictus pupae were associated with tires in 2009 (OR = 10.87) and drums, tires, and jars in 2010 (drums OR = 3.05; tires OR = 3.45, jars OR = 6.59). Compared with water storage vessels, containers used for hygiene, cooking, and drinking were 80% less likely to harbor Ae. albopictus pupae in 2010 (OR = 0.20), and discarded waste was associated with a 3.64 increased odds of infestation. Vector control efforts should focus on source reduction of water storage containers, particularly concrete jars and tires.
我们评估了老挝 Nam Theun 2 号新水电站附近登革热和基孔肯雅热病毒载体的风险因素。在距离省会城市 40 公里以内的地方发现了埃及伊蚊的幼虫，但在整个地区都发现了白纹伊蚊。埃及伊蚊的蛹最常见于储水罐（优势比 [OR] = 4.72）和轮胎（OR = 2.99），而 2009 年白纹伊蚊的蛹与轮胎有关（OR = 10.87），2010 年与桶、轮胎和罐子有关（桶 OR = 3.05；轮胎 OR = 3.45，罐子 OR = 6.59）。与储水容器相比，2010 年用于卫生、烹饪和饮用水的容器中白纹伊蚊的蛹减少了 80%（OR = 0.20），而废弃废物与感染风险增加 3.64 倍有关。病媒控制工作应重点减少储水容器的水源，特别是混凝土罐和轮胎。
