In late summer and fall 1997, Aedes albopictus mosquitoes were found in Peoria, Illinois, a long recognized focus of La Crosse virus transmission. Larvae were found in tires and other artificial containers, biting adults were recovered, and eggs were collected in oviposition traps within a 25-ha area. One chipmunk trapped < 0.25 km from the infested area tested positive for neutralizing antibodies against La Crosse virus.
1997年夏末秋初，在伊利诺伊州皮奥里亚发现了白纹伊蚊，该地长期以来一直是拉克罗斯病毒传播的公认疫源地。在轮胎和其他人工容器中发现了幼虫，捕获了叮咬人的成虫，并在25公顷区域内的产卵诱捕器中收集到了卵。在距离疫区不到0.25公里处捕获的一只花栗鼠检测出针对拉克罗斯病毒的中和抗体呈阳性。
