Community-Acquired Pneumonia and Coccidioidomycosis

Several studies have indicated that 15-30% of community-acquired pneumonia in the hyper-endemic population centers of southern Arizona is caused by coccidioidomycosis. In 2007, the Arizona Department of Health Services recommended that all patients presenting with community-acquired pneumonia in these areas be tested for coccidioidomycosis. See the poster below for testing patients with community-acquired pneumonia for coccidioidomycosis.


The University of Arizona Valley Fever Center for Excellence provides free continuing medical education (CME) on coccidioidomycosis. The CME is available online at the Valley Fever Center for Excellence website. A CME event is held every year, usually in the fall in Tucson or Phoenix. This event is held in conjunction with the annual Valley Fever Awareness Week. Check the Center’s webpage for updated information. A recorded version of the CME is also available in Spanish.
