Harris County, Texas, is an endemic area of St. Louis encephalitis (SLE); and an active surveillance program that monitors SLE virus activity in mosquitoes, birds, and humans has been in place there for the past 28 years. In June of 2002, West Nile (WN) virus appeared in Houston and quickly spread throughout the region. This report describes the results of 12 years of SLE surveillance in Harris County and the contrasting pattern of WN virus activity, when it arrived in 2002. Our data indicate that both SLE and WN viruses can coexist, despite their ecologic, antigenic, and genetic similarities, and that both viruses will probably persist in this geographic region.
得克萨斯州哈里斯县是圣路易斯脑炎（SLE）的地方性流行区；在过去28年里，当地实施了一项监测蚊子、鸟类和人类中SLE病毒活动的主动监测计划。2002年6月，西尼罗河（WN）病毒出现在休斯敦并迅速蔓延至整个地区。本报告描述了哈里斯县12年SLE监测结果以及WN病毒于2002年出现后的不同活动模式。我们的数据表明，尽管SLE和WN病毒在生态学、抗原性和基因方面存在相似性，但它们仍可共存，且这两种病毒可能会在该地理区域持续存在。
