Valley fever
Valley fever (also called coccidioidomycosis or “cocci”) is a reportable disease in California, which means healthcare providers and laboratories that diagnose a case of Valley fever must report it to their local health department. The California Department of Public Health (CDPH) uses data on Valley fever cases to track trends and better understand who is affected by Valley fever.
Data and Publications
CDPH provides two types of surveillance updates on reported Valley fever cases in California: (1) provisional monthly updates and (2) final year-end updates. Data are provided in dashboard and report formats.
Dashboards
CDPH also periodically publishes more focused Valley fever reports in journals, including surveillance summaries, analyses of hospital and death data, and reports summarizing Valley fever outbreaks. See below for some of CDPH’s Valley fever publications:
