About the Data
Description of the data source, numerator, denominator, survey questions, and other relevant details about the national estimate.
Number of persons aged 65 years and older with a laboratory-confirmed invasive pneumococcal infection in the past 12 months
Number of persons aged 65 years and older
An invasive pneumococcal infection is defined as a laboratory-confirmed isolation of Streptococcus pneumoniae from a normally sterile site (blood, cerebral spinal fluid, etc.).
FOR SINGLE DATA YEARS: Case rates are calculated based on the resident population of the ABCs surveillance areas 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, 2010 –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. Missing race data was multiply imputed and surveillance rates were standardized to the racial distribution of the US population using the NCHS bridged-race vintage 2010 postcensal file.
