Vaccine Preventable Disease Cases by County and Year

These data contain counts of Immunization Branch-related disease cases among California residents by county, disease, and year.

The California Department of Public Health (CDPH) maintains a mandatory, passive reporting system for a list of communicable disease cases and outbreaks. The CDPH Immunization Branch conducts surveillance for vaccine preventable diseases. Health care providers and laboratories are mandated to report cases or suspected cases of these communicable diseases to their local health department (LHD). LHDs are also mandated to report these cases to CDPH.

For more information on the data sources, methods and limitations see the attached Notes file.

This dataset updates every year
