IID-25.1 Reduce new hepatitis B infections in adults aged 19 and older
About the Data
Description of the data source, numerator, denominator, survey questions, and other relevant details about the national estimate.
Number of symptomatic hepatitis B cases reported in the past 12 months among persons aged 19 years and over
Total population of persons aged 19 years and over in reporting states
Data are rates per 100,000 population based on the number of symptomatic cases of acute hepatitis B reported to NNDSS. A case definition for new symptomatic cases of hepatitis B is available from CDC.
FOR SINGLE DATA YEARS: Case rates are calculated based on the resident population of the United States for the data year involved. For census years (e.g. 2010), population counts enumerated as of April 1 are used. For all other years, populations estimates as of July 1 are used. Postcensal population estimates are used in rate calculations for years after a census year and match the data year vintage (e.g. July 1, 2011 resident population estimates from Vintage 2011 are used as the denominator for 2011 rates). Postcensal population estimates are used in rate calculations for the years between censuses (e.g. 1991-1999, 2001-2009). Race-specific population estimates for 1991 and later use bridged-race categories.
