  • U: Unavailable — The reporting jurisdiction was unable to send the data to CDC or CDC was unable to process the data.
  • -: No reported cases — The reporting jurisdiction did not submit any cases to CDC.
  • N: Not reportable — The disease or condition was not reportable by law, statute, or regulation in the reporting jurisdiction.
  • NN: Not nationally notifiable — This condition was not designated as being nationally notifiable.
  • NP: Nationally notifiable but not published.
  • NC: Not calculated — There is insufficient data available to support the calculation of this statistic.
  • Cum: Cumulative year-to-date counts.
  • * Case counts for reporting years 2023 and 2024 are provisional and subject to change. Cases are assigned to the reporting jurisdiction submitting the case to NNDSS, if the case's country of usual residence is the U.S., a U.S. territory, unknown, or null (i.e. country not reported); otherwise, the case is assigned to the 'Non-U.S. Residents' category. Country of usual residence is currently not reported by all jurisdictions or for all conditions. For further information on interpretation of these data, see https://www.cdc.gov/nndss/data-statistics/readers-guides/.
  • † Previous 52 week maximum and cumulative YTD are determined from periods of time when the condition was reportable in the jurisdiction (i.e., may be less than 52 weeks of data or incomplete YTD data).
  • § Beginning in January 2022, only confirmed cases are published to align with the approved CSTE position statement 21-ID-06, whereas in previous years, all case classification statuses were published. This change may cause a decrease in published case counts when compared to previous years.
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 in alphabetical order by condition. 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.
