These are provisional cases of selected 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
printed in the back of the Morbidity and Mortality Weekly Report (MMWR).
Cases reported by state health departments to CDC for weekly publication
are provisional because of ongoing revision of information and delayed reporting.
Case counts in these query tables are presented as they were published in the MMWR
issues. Therefore, numbers listed in later MMWR weeks may reflect changes made to
these counts as additional information becomes available. More information.
