2000年，西尼罗河病毒在美国的传播在纽约的斯塔顿岛最为严重，在那里发生了10起人类神经系统疾病和2起马神经系统疾病。WN病毒是从骚扰伊蚊、尖音库蚊、白纹伊蚊、在点翅按蚊中检测到WN病毒RNA。Cx每周最低感染率（MIR）升高。在第一次人类疾病发生前两周，就出现了尖音和死鸟密度增加。一个地区的蚊子MIRs和死鸟密度增加可能是人类感染风险增加的指标。提出了一个包含Cx管道和Cx的传输模型。restuans作为鸟类中主要的地方病和流行病媒介，Cx salinarius作为人类的主要桥梁媒介，以及伊蚊/黄斑伊蚊属。作为马感染的桥梁媒介。
West Nile (WN) virus transmission in the United States during 2000 was most intense on Staten Island, New York, where 10 neurologic illnesses among humans and 2 among horses occurred. WN virus was isolated from Aedes vexans, Culex pipiens, Cx. salinarius, Ochlerotatus triseriatus, and Psorophora ferox, and WN viral RNA was detected in Anopheles punctipennis. An elevated weekly minimum infection rate (MIR) for Cx. pipiens and increased dead bird density were present for 2 weeks before the first human illness occurred. Increasing mosquito MIRs and dead bird densities in an area may be indicators of an increasing risk for human infections. A transmission model is proposed involving Cx pipiens and Cx. restuans as the primary enzootic and epizootic vectors among birds, Cx salinarius as the primary bridge vector for humans, and Aedes/Ochlerotatus spp. as bridge vectors for equine infection.
