Coccidioidomycosis in California

We used hospital discharge data to estimate incidence and distribution of coccidioidomycosis-associated hospital-izations in California. For 1997–2002, the average annual rate of hospitalization was 3.67 per 100,000 population. County of residence, older age, black race, male sex, HIV infection, and pregnancy were strongly associated with in-creased risk for hospitalization.
