In continuation of a series of studies of arboreal mosquitos as virus vectors in Uganda, 12 strains of Zika virus and one strain of another Group B arbovirus were isolated between November 1961 and June 1963 from pools of Aedes (Stegomyia) africanus caught on a 120-foot (36.5-m) tower in Zika forest. For five strains it is known at what height the mosquitos were caught: one was from mosquitos taken at ground level, and the other four were from mosquitos taken in or above the upper canopy after sunset. No small mammal trapped in the forest either on the ground or in the trees showed serum antibody for Zika virus.These findings suggest that in Zika forest, A. (S.) africanus becomes infected from a virus reservoir that is probably not among the small animals tested and that infected mosquitos are liable to be spread widely beyond the forest by convection currents above the tree-tops in the first two or three hours after sunset.
作为乌干达关于树栖蚊子作为病毒载体的一系列研究的延续,在1961年11月至1963年6月期间,从齐卡森林中一座120英尺(36.5米)高的塔上捕获的非洲伊蚊(埃及伊蚊亚属)样本中,分离出了12株寨卡病毒和1株另一种B组虫媒病毒。对于其中5株病毒,已知捕获蚊子的高度:1株来自地面捕获的蚊子,另外4株来自日落之后树冠层或树冠层以上捕获的蚊子。在森林中地面或树上捕获的小型哺乳动物均未显示出寨卡病毒血清抗体。这些发现表明,在齐卡森林中,非洲伊蚊(埃及伊蚊亚属)从一个可能不在所检测的小动物中的病毒储存宿主感染,并且受感染的蚊子在日落后的头两三个小时内可能会通过树顶上方的对流气流广泛传播到森林之外。
