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/ 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.
