Valley fever, additionally known as coccidioidomycosis, is an an infection attributable to a fungus that lives in the soil in the southwestern United States and elements of Mexico and Central and South America. It is contracted by respiratory in the microscopic fungal spores from the air, though most individuals who breathe in the spores don’t get sick, the C.D.C. mentioned.
