From 1971 to 2012, in New York State, years with human Eastern equine encephalitis (EEE) were more strongly associated with the presence of Aedes canadensis, Coquillettidia perturbans and Culiseta melanura mosquitoes infected with the EEE virus (Fisher's exact test, one-sided P = 0.005, 0.03, 0.03) than with Culiseta morsitans, Aedes vexans, Culex pipiens-restuans, Anopheles quadrimaculatus or Anopheles punctipennis (P = 0.05, 0.40, 0.33, 1.00, 1.00). The estimated relative risk of a case in a year in which the virus was detected vs. not detected was 14.67 for Ae. canadensis, 6.38 for Cq. perturbans and 5.50 for Cs. morsitans. In all 5 years with a case, Cs. melanura with the virus was detected. In no year was there a case in the absence of Cs. melanura with the virus. There were 18 years with no case in the presence of Cs. melanura with the virus. Such observations may identify the time of increased risk, and when the methods may be used to prevent or reduce exposure to vector mosquito species in this geographic region.
从 1971 年到 2012 年，在纽约州，感染东部马脑炎病毒的库蚊、库蚊和库蚊与人类感染东部马脑炎（EEE）的年份之间存在更强的相关性（Fisher 精确检验，单侧 P=0.005、0.03、0.03），而不是库蚊、库蚊、库蚊、库蚊和库蚊（P=0.05、0.40、0.33、1.00、1.00）。在检测到病毒的年份与未检测到病毒的年份相比，病例的估计相对风险为 14.67 倍、14.67 倍和 5.50 倍。在所有 5 年有病例的年份中，都检测到了携带病毒的库蚊。在没有携带病毒的库蚊的年份，没有发生病例。在携带病毒的库蚊存在的情况下，有 18 年没有发生病例。这些观察结果可能确定了风险增加的时间，以及何时可以使用这些方法来预防或减少该地理区域中媒介蚊子种类的暴露。
