Coccidioidomycosis

Coccidioidomycosis is a common infectious disease in the southwestern United States. Although Coccidioides species are not endemic in other areas of the country, the rapid population growth in the southwestern United States in recent decades and the increase in tourism mean that many people travel to the Southwest and return home before developing the clinical syndrome of coccidioidomycosis. In this respect, coccidioidomycosis is a disease of national importance. It can occur in various manifestations: acute pneumonia, chronic progressive pneumonia, pulmonary nodules and cavities, extrapulmonary nonmeningeal disease, and meningitis. The diagnosis is often made on the basis of serologic findings. Treatment is usually with an azole or amphotericin B, depending on the clinical manifestations and the immune status of the host. We discuss the most common clinical manifestations, the best way to make the diagnosis, and the treatment of common infections.
