Idaho incidence rates are calculated using population estimates published by the U.S. Census Bureau. Prior to 2005, annual rates were recalculated if the U.S. Census Bureau population estimates were revised. This practice has been discontinued and the population estimate used to calculate incidence rates are provided.
United States rates are from the most recent Centers for Disease Control and Prevention (CDC) publication MMWR Summary of Notifiable Diseases, United States (http://www.cdc.gov/mmWR/summary.html).
