California Pandemic (H1N1) 2009 Virus Provisional Data Table - August 28, 2010 (PDF) Opens in a new browser window.- by local health jurisdiction

Change in display of reported data as of October 24, 2009: The table providing H1N1 Flu hospitalization and death information by county has been changed to show county-by-county information on severe cases (deaths and cases requiring intensive care), cases requiring intensive care and deaths due to H1N1 Flu. The reason for this change is that county-specific information on hospitalizations cannot be verified on a per-case basis now that these data are provided by local health departments on an aggregate basis. The information on intensive care cases and deaths continues to be provided on a per-case basis.
