Coccidioidomycosis: A persistent threat to deployed populations

The world-wide deployability of aircrew members exposes them to a peculiar array of medical problems. Non-immune populations, upon deployment to endemic areas, may present to the deployed flight surgeon with acute, poorly recognizable syndromes, such as acute coccidioidomycosis. Alternatively, the acquisition of the chronic progressive form of coccidioidomycosis in endemic areas may be a problem for the flight surgeon, who may be faced with a poorly recognizable syndrome which first manifests itself weeks to months after the crewmember's return from deployment. We describe three cases of coccidioidomycosis in service members that highlight the difficulty in the diagnosis of this disease. These cases prompted an epidemiologic survey of recent cases of coccidioidomycosis among Air Force beneficiaries, presented here, to better define the impact of this disease on personnel assigned to endemic areas. A brief discussion of the epidemiologic and clinical features of the disease and of the aeromedical disposition of the aviator is presented.
