摘　　要：登革热病毒可在媒介伊蚊体内垂直传递,且在蚊媒滞育卵中长期存活并随之扩散,因此,垂直传递通常被认为是一种水平传播不利条件下的病毒保存机制。但其在自然界中的普遍性并不明确,尤其在流行病学中的作用地位一直存在争议。现就登革热病毒的垂直传递和伊蚊滞育与登革热病毒的传播关系进行综述,以探讨登革热病毒在寒冷冬季或流行间歇期的保存并过渡至下个流行季节的过程,为登革热的监测和防治研究提供参考依据。Dengue viruses could be transmitted vertically by vector Aedes mosquitoes, and survive a long time in diapausingeggs and then disseminate with these eggs. Therefore, vertical transmission has been suggested to be a possible mechanismfor the persistence of dengue fever viruses during adverse conditions for horizontal transmission. However, it is unclear howwidespread it is in nature, and its importance in the epidemiology of this disease is still debated. Here, we review theliterature on the relationships of viral vertical transmission and Aedes diapause, to discuss how dengue fever viruses surviveduring cold winter or inter-epidemic phase and then transit to next epidemic season. This review will provide somereferences for the research on dengue fever monitoring and controlling.
