Coccidioidomycosis, a fungal respiratory infection also known as Valley fever, has increased substantially in several southwestern US states since 1998.
An analysis of Valley fever cases reported in Arizona, California, Nevada, New Mexico, and Utah showed that the combined incidence in those states increased from 5.3 per 100 000 population in 1998 to 42.6 in 2011. Of 111 717 cases reported to the Centers for Disease Control and Prevention (CDC) from 28 states and the District of Columbia during that time period, 66% were in Arizona and 31% were in California. Fewer than 1% were in nonendemic states.
