Footnote: Data are provided for vaccine-preventable childhood diseases reported by the California Dept. of Public Health. Varicella cases are reported for most, but not all, U.S. states. Only varicella cases resulting in hospitalization or death are reported for California and counties. The notation S refers to data that have been suppressed because there were more than 0 but fewer than 20 reported cases, and to non-comparable rates. N/A means that data are not available.
