Zika virus disease is a great concern in different parts of the world, and it has become a Public Health Emergency of International Concern. The global pandemic of ZIKV in 2015 prompted concern among scientific community. Zika is a flavivirus of the family Flaviviridae transmitted by mosquitoes. Natural vertical transmission is an ecological strategy that arboviruses adopt to ensure their survival inside the mosquito vector during harsh conditions or interepidemic periods when horizontal transmission is difficult. ZIKV is vertically transmitted from infected females to its offspring. This review has concluded various studies regarding the vertical transmission ability of different mosquito species for ZIKV. Previously Aedes aegypti was considered to be a major vector, however Aedes albopictus and Culex quinquifasciatus are discovered to have the similar vertical transmission potential. Different studies shown that natural vertical transmission has been detected in mosquito species which are not implicated as possible vectors. It leads to the possibility that many other mosquito species may be potential ZIKV vectors.
Zika 病毒病在世界不同地区引起了极大关注，现已构成国际关注的突发公共卫生事件。2015 年，ZIKV 在全球范围内大规模流行，引起科学界的关注。Zika 是黄病毒科黄病毒属的一种病毒，通过蚊子传播。自然垂直传播是一种生态策略，蚊媒病毒通过这种策略在恶劣条件下或难以进行水平传播的间疫情期确保其在蚊子媒介内的存活。ZIKV 可从受感染的雌性垂直传播给其后代。本综述总结了关于不同蚊子物种对 ZIKV 的垂直传播能力的各种研究。以前认为埃及伊蚊是主要传播媒介，但现已发现白纹伊蚊和致倦库蚊也具有相似的垂直传播潜力。不同的研究表明，在尚未被认为是可能传播媒介的蚊子物种中已经检测到自然垂直传播。这使得许多其他蚊子物种可能成为潜在的 ZIKV 传播媒介。
