Tropical Diseases - Yellow fever
Yellow fever , which sometimes produces symptoms similar to those of malaria, also is transmitted by a mosquito. But yellow fever is a virus disease carried by the Aedes mosquito.
Yellow fever also can be harbored by other animals, while the malaria organism that affects humans is not transmitted between humans and lower animals. Like malaria, yellow fever has in past years spread deeply into North America with cases reported along the Gulf Coast, the Mississippi River Valley, and as far north as Boston. A vaccine is available for protection against yellow fever.
