To characterize trends in and the impact of coccidioidomycosis in Arizona, the Arizona Department of Health Services (ADHS) analyzed surveillance, death-certificate, and hospital discharge data. This report summarizes the findings, which indicate that, during 1990-1995, coccidioidomycosis in Arizona disproportionately affected persons aged greater than or equal to 65 years and persons with human immunodeficiency virus (HIV) infection.
