Improved access to public health data

On January 17, 2023, the National Notifiable Diseases Surveillance System (NNDSS) released a new table format for NNDSS weekly data on CDC's Wide-ranging Online Data for Epidemiologic Research (WONDER)!

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

In this new format, each condition is presented in a separate table. The new format will

  • Allow users of NNDSS weekly data to focus on the condition of interest.
  • Enhance user experience compared to the previous, mixed condition(s) data tables.
  • Make the NNDSS weekly data, text, and PDF files easier to use.

We invite you to explore these exciting new features! If you need additional information or have questions, please contact the CDC Electronic Data Exchange mailbox at edx@cdc.gov with the subject "NNDSS Weekly WONDER Tables."
