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.
Causes of Valley Fever. One of the main causes of valley fever is the inhalation of fungus spores present in the soil (generally in dry desert conditions). You may think you are coming down with a cold when you are suffering from valley fever symptoms. The major symptoms relate to the respiratory system and it may start with a cough.
