Coccidioidomycosis, commonly known as Valley Fever, is a fungal infection caused by the Coccidioides species. This fungus is found in soil, particularly in arid regions like the southwestern United States. When the soil is disturbed, spores can become airborne and inhaled, leading to respiratory symptoms such as cough, fever, and fatigue. Most healthy individuals recover without treatment, but some may develop severe illness, especially those with weakened immune systems. Diagnosis is typically made through blood tests or imaging studies. Treatment may involve antifungal medications for those with more serious symptoms or complications.
