CDC Releases New, Interactive Tool for Annual NNDSS Data

On December 15, 2022, CDC’s Wide-ranging Online Data for Epidemiologic Research (WONDER) and the National Notifiable Diseases Surveillance System (NNDSS) released a new interactive tool for users of NNDSS annual data on CDC WONDER.

A key data source for public health, the NNDSS annual tables provide information on cases of selected infectious national notifiable diseases and conditions sent to CDC by U.S. states and territories. These enhancements are part of CDC’s efforts to modernize public health data systems

The new interactive tool:

  • Allows users of NNDSS annual data to create data visualizations customized to their needs.
  • Offers more flexibility to focus their analyses and understand trends and patterns, such as comparing NNDSS data across years, specific populations, diseases and conditions, and geographic areas.
  • Enhances user experience compared to the current, fixed format annual data tables.
  • Makes NNDSS data more transparent.

With the release of these new interactive features, CDC is not adding any new data elements to NNDSS data displays or the ability to stratify existing NNDSS data elements in ways not previously available.
