The yellow fever virus is transmitted to humans by infected mosquitoes. Severity of the illness ranges from influenza-like symptoms to severe hepatitis and hemorrhagic fever. The yellow fever virus survives in nature by mosquito-borne transmission between nonhuman primates. Transmission by mosquitoes from one human to another occurs during epidemics of urban yellow fever.
