​Data Notes

• Data presented in this dashboard may be different from previously published data because of delays that are inherent to case reporting, laboratory reporting, and epidemiologic investigation.​​
  

• Case counts within small populations have been suppressed to de-identify data that are publicly released. This process helps maintain confidentiality of case-patients in small populations. For more information, see Publication Scoring Criteria published in the California Department of Health Care Services Data De-Identification Guidelines (PDF).
  

• Percent change in cases was calculated by subtracting the average of cases in 2022 and 2023 from the number of cases in 2024, dividing that difference by the average of cases in 2022 and 2023, and then multiplying by 100 to convert that quotient to a percentage. A positive percent change of 50% is the same as saying the number of cases increased by half the original amount. A positive percent change of 100% is the same as saying the number of cases doubled from the original amount. A positive percent change of 200% is the same as saying the number of cases tripled from the original amount.​
  

• ​Year of report is based on estimated illness onset date, which is the date closest to the time when symptoms first appeared. For cases which date of illness onset was not recorded, estimated date of illness onset was selected as the earliest of: date of diagnosis, date the case was reported to or received by the California Department of Public Health (CDPH), date of laboratory specimen collection, or date of patient death.​

• Since Valley fever can occur as a chronic condition and be reported more than once, only the first report of Valley fever per person was included using a de-duplication method spanning multiple reporting years.​
  

• This dashboard includes data that were (a) reported by healthcare providers and laboratories on patients with potential positive and non-negative (e.g., inconclusive, indeterminate) laboratory results for coccidioidomycosis, and then (b) preliminarily marked by local health jurisdictions as Confirmed, Probable, or Suspect. Data in this dashboard are provisional and have not been fully reviewed and confirmed by California local health jurisdictions in accordance with the Coccidioidomycosis CSTE Case Definition (PDF).
  

• Combined provisional Suspect, Probable, and Confirmed case counts in this dashboard may differ from counts of Confirmed cases that CDPH will eventually publish in final year-end surveillance reports.
