Yellow fever is caused by the yellow fever virus (YFV), also called Flavivirus. The virus is transmitted by female mosquitos, who pick it up from monkeys or other humans, then delivers it to a new human when they bite and suck blood. The disease cannot be spread from person to person. Mosquitoes breed in tropical rainforests, humid and semi-humid environments, and around bodies of still water.
