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.
What is yellow fever? Yellow fever is a disease caused by a flavivirus that is transmitted by the bite of an infected mosquito. It gets its name from the yellowing of the skin and eyes (jaundice) that occurs when the virus attacks the liver. Yellow fever can be prevented by a vaccine.
