Yellow fever, a mosquito-borne viral disease, is not normally found in the U.S. It typically appears in travelers to other countries where the disease is more prevalent, such as sub-Saharan Africa and tropical South America. It is maintained in nature as mosquitoes pass the disease among themselves, to monkeys, then back again. Humans may also serve as hosts for the disease.
