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.
  • Weekly tables for 1952-2017 published in the MMWR are available at CDC Stacks MMWR, and weekly tables starting in 2018 are available at CDC Stacks NNDSS (once in CDC Stacks NNDSS select "Weekly Tables" in the "Genre" box at the left).
