What is Valley Fever? Valley Fever (coccidioidomycosis, or cocci) is caused by the soil-dwelling fungus, Coccidioides immitis. The tiny seeds, or spores, become wind-borne and are inhaled into the lungs, where the infection starts. When soils containing the fungus are disturbed and dust is raised, spores may be inhaled with the dust.
Yellow Fever is a mosquito-borne viral disease. The disease occurs in tropical and subtropical areas and can affect both sexes, all ages and races. Jungle yellow fever, of tropical Central and South America, occurs predominantly among adult males 20 to 40 years old who are exposed in the tropical forests.
