Yellow fever is a mosquito-borne viral disease. Illness ranges in severity from an influenza-like syndrome to severe hepatitis and hemorrhagic fever. Yellow fever is caused by a zoonotic virus that is maintained in nature by transmission between nonhuman primates and mosquito vectors. In some situations, humans may serve as the primary host in the transmission cycle (“urban yellow fever”).
