As of January 2025, weekly NNDSS PDF and text table formats will be available via CDC Stacks, a public online data repository instead of on WONDER. The HTML format has been updated to improve user experience and data can be found on data.cdc.gov, a publicly available catalog of data resources. This change reflects efforts to make CDC data more responsive and efficient. For questions, email NNDSSWeb@cdc.gov.

Notes:
  • These are weekly cases of selected infectious national notifiable diseases, from the National Notifiable Diseases Surveillance System (NNDSS). NNDSS data reported by the 50 states, New York City, the District of Columbia, and the U.S. territories are collated and published weekly as numbered tables. Cases reported by state health departments to CDC for weekly publication are subject to ongoing revision of information and delayed reporting. Therefore, numbers listed in later weeks may reflect changes made to these counts as additional information becomes available. Case counts in the tables are presented as published each week. See also Guide to Interpreting Provisional and Finalized NNDSS Data.
  • Weekly tables since 1996 are available on CDC WONDER.
  • Weekly tables since 2014 are available on Data.CDC.gov.
