A common fungal lung infection in southern Arizona — and a condition we diagnose and treat regularly
Valley Fever (coccidioidomycosis) is a fungal infection caused by inhaling Coccidioides spores from desert soil. When soil is disturbed by wind, construction, or farming, spores become airborne. Casa Grande sits in Pinal County — one of Arizona's highest-risk areas. Thousands of Arizonans are affected each year, with seasonal peaks in summer and fall.
