NN: Not nationally notifiable - This condition was not designated as being nationally notifiable. NP: Nationally notifiable but not published.

Cum: Cumulative year-to-date counts. * Case counts for reporting year 2023 are provisional and subject to change. For further information on interpretation of these data, see https://www.cdc.gov/nndss/data-statistics/readers-guides/ § 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 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.
