In the course of a dengue outbreak, 765 larvae and 20 pupae were collected in Noumea and in Wallis island around patients premises, to investigate a possible natural infection. On 15 pools made of 335 Aedes aegypti larvae and pupae, 3 appeared to be infected. Dengue virus type 1 was the only serotype identified. Minimum infection rate reached 1: 112. In New Caledonia, the local strains of Aedes aegypti can insure the survival of dengue 1 virus between outbreaks, due to a vertical infection of their progeny.
在登革热疫情期间，在努美阿和瓦利斯岛患者住所周围收集了765只幼虫和20只蛹，以调查可能的自然感染情况。在由335只埃及伊蚊幼虫和蛹组成的15个样本池中，有3个似乎受到了感染。1型登革病毒是唯一鉴定出的血清型。最低感染率达到1:112。在新喀里多尼亚，埃及伊蚊的本地菌株可以确保登革热1型病毒在疫情爆发期间存活，这是由于其后代的垂直感染。
