Notice to Readers: New Web Location for Weekly and Annual NNDSS Data

Abstract

To improve the usability, availability, quality, and timeliness of surveillance data as part of the CDC Surveillance Strategy ( 1 ), CDC now provides users a convenient way to access notifiable infectious and noninfectious disease data through the National Notifiable Diseases Surveillance System (NNDSS) website. CDC has redesigned the data and statistics section of the NNDSS website to be a one-stop shop where users can find both detailed information about the notifiable disease data and links to the weekly and annual data. Although these data are no longer published in MMWR, users can easily access the information on the NNDSS website. To ease the transition, MMWR also links users from its website to the new location on the NNDSS website. Weekly Reporting Starting this week, CDC transitions the reporting of NNDSS weekly data to the redesigned NNDSS Data and Statistics webpage https://wwwn.cdc.gov/nndss/data-and-statistics.html. This site contains links to infectious disease data tables that are available in HTML, text, and PDF formats and hosted on the CDC WONDER platform. Figure 1, which was previously published in the MMWR weekly report, is also available. In addition, the webpage provides NNDSS documentation, including how the data are collected and reported, publication criteria, notes about interpreting data, and the list of notifiable conditions by year. Annual Reporting CDC transitioned the reporting of NNDSS annual data on November 3, 2017. This information is available on the NNDSS Data and Statistics webpage at https://wwwn.cdc.gov/nndss/data-and-statistics.html and includes links to infectious disease data tables that are available in HTML, text, and PDF formats and hosted on the CDC WONDER platform. The webpage also provides links to noninfectious conditions and disease outbreak surveillance reports published by CDC programs and hosted on the CDC WONDER platform. In addition, the webpage provides the following resources: documentation for NNDSS infectious diseases and noninfectious conditions and disease outbreaks, including how the data are collected, reported, and finalized; publication criteria; notes about interpreting data; and the list of notifiable conditions by year. Consolidating the notifiable disease data on the NNDSS website is part of the NNDSS Modernization Initiative (NMI) strategy to streamline NNDSS and access to data for users; NMI is a component of the CDC Surveillance Strategy. This consolidation of information reflects the recommendations of a CDC-wide workgroup, consisting of representatives from the CDC Excellence in Science Committee, the Surveillance Science Advisory Group, and MMWR, to make more data available online and to allow MMWR to focus on publishing scientific and actionable surveillance reports.
