It's spread by a certain kind of mosquito known as Aedes, tropical bloodsuckers that spread other flaviviruses.

它由一种称为伊蚊的蚊子传播，这种蚊子是传播其他黄病毒的热带吸血鬼。

With most flaviviruses though, the virus isn't able to replicate enough in the human host to actually be able to reinfect another mosquito, and so the human is considered a dead-end-host.

然而对于大多数黄病毒来说，病毒在人类宿主体内的复制量较低，很难感染另一只蚊子，此时人类就是终端宿主。
