NUMEROUS former military personnel of World War II (actual figures not available) have served in the southwestern desert area of this country, where coccidioidomycosis is endemic. The presence of these troops in large numbers has stimulated study of the disease.

These and other fundamental data have already been described amply in the literature. The primary purpose is to present data on a
