西尼罗河病毒 (WNV) 是一种蚊媒病毒，自 2002 年引入以来，已在临床上影响了休斯敦都会区的数百名居民。这项研究旨在确定居住在靠近水源的地方是否会增加感染西尼罗河病毒的几率。我们使用美国人口普查局数据的人口规模比例模型确定了 356 例符合条件的西尼罗河病毒阳性病例和 356 例对照。我们发现，生活在流动缓慢的水源附近与人类感染的几率增加存在统计学相关性，而生活在流动缓慢的水源附近则与人类感染的几率降低相关。居住在植被而非混凝土的海湾附近也显示出感染风险增加。缓慢移动和植被环绕的水源栖息地似乎有利于蚊子-人类传播循环。资源有限的卫生实体可以使用这些方法来确定高风险区域，以进行虫媒病毒疾病监测和有效的蚊子管理举措。
West Nile virus (WNV), a mosquito‐borne virus, has clinically affected hundreds of residents in the Houston metropolitan area since its introduction in 2002. This study aimed to determine if living within close proximity to a water source increases one’s odds of infection with WNV. We identified 356 eligible WNV‐positive cases and 356 controls using a population proportionate to size model with US Census Bureau data. We found that living near slow moving water sources was statistically associated with increased odds for human infection, while living near moderate moving water systems was associated with decreased odds for human infection. Living near bayous lined with vegetation as opposed to concrete also showed increased risk of infection. The habitats of slow moving and vegetation lined water sources appear to favor the mosquito‐human transmission cycle. These methods can be used by resource‐limited health entities to identify high‐risk areas for arboviral disease surveillance and efficient mosquito management initiatives.
