During 1990, Dengue-2 (DEN-2) virus was isolated for the first time from mosquitoes (Aedes furcifer, six isolates; Ae. taylori, six isolates; Ae. luteocephalus, seven isolates) collected during an epidemic in which DEN-2 virus also was isolated from humans. Numerous isolations have been made previously from mosquitoes in the absence of human infection. In Senegal, DEN-2 virus appears to be maintained in an enzootic cycle and, therefore, plays an expanding role in human disease and increases the need for effective surveillance in mosquito populations.
1990年期间，首次从在一次疫情期间采集的蚊子（叉尾伊蚊，6株分离株；泰勒伊蚊，6株分离株；黄头伊蚊，7株分离株）中分离出登革2型（DEN-2）病毒，在此次疫情中也从人类身上分离出了DEN-2病毒。此前在没有人类感染的情况下，已多次从蚊子中分离出该病毒。在塞内加尔，DEN-2病毒似乎在动物疫源循环中持续存在，因此，它在人类疾病中所起的作用越来越大，也增加了对蚊子种群进行有效监测的必要性。
