Flavivirus - Wikipedia
Flaviviruses share several common aspects: common size (40–65 nm), symmetry (enveloped, icosahedral nucleocapsid), nucleic acid (positive-sense, single-stranded RNA around 10,000–11,000 bases), and appearance under the electron microscope.

黄病毒属（Flavivirus）是一大群具有包膜的单正链RNA病毒。 该类病毒通过吸血的 节肢动物 （蚊、蜱、 白蛉 等）传播而引起感染。 过去曾归类为 虫媒病毒。 在我国主要流行的黄病毒有 乙型脑炎病毒 、 森林脑炎病毒 和 登革病毒。 黄病毒属 (Flavivirus)是一大群具有包膜的单正链RNA病毒。 这 类病毒 通常通过吸血的 节肢动物 (蚊、蜱、 白蛉 等)传播，故过去曾归类为 虫媒病毒 (arbovirus)B组。 由于“虫媒病毒”一词在 分类学 中含义不够准确，所以目前已经不再使用。 …
Flaviviridae - Wikipedia
Flaviviridae is a family of enveloped positive-strand RNA viruses which mainly infect mammals and birds. [1] . They are primarily spread through arthropod vectors (mainly ticks and mosquitoes). [2] .

The Continued Emerging Threat of Flaviviruses - PMC
Flaviviruses are vector-borne RNA viruses that can emerge unexpectedly in human populations and cause a spectrum of potentially severe diseases including hepatitis, vascular shock syndrome, encephalitis, acute flaccid paralysis, and congenital abnormalities and fetal death.
Flavivirus - an overview | ScienceDirect Topics
Flaviviruses are insect-borne, positive-sense single-stranded RNA viruses that include human pathogens of major health concern, including yellow fever virus (YFV), dengue virus (DENV), Zika virus (ZIKV), West Nile virus (WNV), and Japanese encephalitis virus (JEV).
Flaviviruses - PMC
Flaviviruses replicate in the salivary glands and are introduced into a new human host together with saliva. Again in contrast to other mosquitoes, A. aegypti lays its eggs individually, dispersed over large areas of still water: this maximises the chance of survival. Although the female avoids dirty or polluted water, eggs can survive in water ...
Alphaviruses (Togaviridae) and Flaviviruses (Flaviviridae)
At least 27 alphaviruses and 68 flaviviruses have been recognized, approximately one-third of which are medically important human pathogens. They vary widely in their basic ecology; each virus occupies a distinct ecologic niche, often with restricted geographic and biologic distribution.
