Causes, incidence, and risk factors:

Coccidioidomycosis is caused by breathing in the spores of a fungus in desert regions. About 60% of acute infections cause no symptoms and are only recognized by a positive coccidioidin skin test. In the remaining 40%, symptoms range from mild to severe.

In the disseminated form of the disease, the infection may spread to the bones, lungs, liver, brain, skin, heart, and pericardium (sac around the heart).

Meningitis occurs in 30 - 50% of cases of disseminated disease. Immunodeficient (immunosuppressed) people -- including those with HIV infection, people with diabetes, and pregnant women of any race -- are more prone to the disease. Recent travel to or residence in southwestern deserts of the U.S. is a risk factor.
