Notice to Readers: NNDSS Tables Have Updated “N” Indicators for 2015 and 2016
Weekly / November 25, 2016 / 65(46);1322
CDC’s National Notifiable Diseases Surveillance System (NNDSS) maintains and annually updates information about whether each Nationally Notifiable Infectious Condition (NNIC) is considered “reportable” (by health care providers, hospitals, laboratories, or other public health reporters) in each reporting jurisdiction. NNDSS personnel within the Division of Health Informatics and Surveillance performed assessments with each reporting jurisdiction to ascertain the reportable disease status of each NNIC for 2015 and 2016. NNICs that are not designated reportable are indicated with an “N”; NNICs that are reportable, but for which no cases were reported, are indicated with a “–” and NNICs that are reportable, but for which data are not available in a jurisdiction, are designated by either “U” or “NA.” These designations are used in the annual MMWR Summary of Notifiable Diseases — United States and in the weekly MMWR Notifiable Diseases and Mortality Tables I and II of provisional NNDSS data.
The assessment results for 2015 and 2016 were used to populate the N indicators for NNDSS data in the MMWR Summary of Notifiable Diseases — United States, 2015 and the NNDSS weekly provisional MMWR Notifiable Diseases and Mortality Tables I and II for 2016, respectively. Assessment results for 2016 also will be used initially to populate the N indicators in the MMWR weekly provisional tables for 2017.
When the data for a specified year are reconciled and finalized, NNDSS reporting exceptions (N indicators) are summarized by NNIC and reporting jurisdiction in a report available at https://wwwn.cdc.gov/nndss/script/downloads.aspx. This report currently includes reporting exceptions data for 2006–2016. The N indicators for 2015 and earlier have been finalized with each reporting jurisdiction. The N indicators for 2016 are provisional until NNDSS data for 2016 have been finalized (next year).
