Improvements in data processing at CDC were applied to 2020 and 2021 data beginning with the tables published for week 47. Case count changes between tables published for week 46 and week 47 may be due to changes in data processing rules and not due to changes in disease levels. TABLE 1g.

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. Maximum - Maximum case count during the previous 52 weeks. * Case counts for reporting year 2021 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/docs/Readers-Guide-WONDER-Tables-20210421-508.pdf †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). § Reporting jurisdictions were informed CDC could receive data for this condition in August 2019. Please note there will be a delay in reporting of case notifications for this condition to CDC. 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.
