Data for selected nationally notifiable diseases reported by the 50 states, New York City, the District of Columbia, and the U.S. territories are collated and published weekly in 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. Therefore, numbers listed in later MMWR weeks may reflect changes made to these counts as additional information becomes available.
