Two NNDSS surveillance resources now available for 2023

To help jurisdictions participating in NNDSS conduct case surveillance, CDC’s NNDSS team posts event codes and other useful surveillance resources on the CDC website.

The team recently posted two new case surveillance resources for 2023:

CDC is planning to post additional resources for 2023 in the coming weeks. These include:

  • list of all NNDSS event codes for 2023,
  • PHIN VADS value sets for the 2023 event code list, and
  • list of 2023 notification requirements.

CDC is also working to update our searchable library of case definitions based on 2023 position statements approved by CSTE.

Case Surveillance Modernization Update

To enhance case surveillance and reduce burden on state, local, and territorial jurisdictions participating in the National Notifiable Diseases Surveillance System (NNDSS), CDC is collaborating with jurisdictions and public health partners to modernize case surveillance.

CDC is sharing recurring, operational progress updates through channels such as Case Surveillance News and monthly eSHARE training webinars. CDC will also share time-sensitive information about actions for jurisdictions, key milestones, and project decisions using the NNDSS email list via edx@cdc.gov.

Key implementation updates for January 2023:

  • The MITRE landscape assessment to define barriers and inform solutions for sending GenV2 core data elements is now expected to begin in March 2023; however, the team is working to expedite required contract processes to try to begin the analysis before March.
  • CDC is continuing to assess jurisdiction needs during the current pause on MMG implementation. This includes developing specific guidance for refocusing performance measures for the Epidemiology and Laboratory Capacity Health Information Systems (ELC HIS) Cooperative Agreement and the Emerging Infections Programs (EIP).
  • The NNDSS team is continuing work with CSTE’s Data Standardization Workgroup and CDC Data Modernization Initiative priority teams to standardize an extended set of core data elements.

Jurisdiction support is critical to the success of this effort. CDC is continuing to work with jurisdictions to better understand their needs and status of MMG onboarding work. CDC encourages jurisdictions to give your input and feedback on any barriers or obstacles your organization may face with implementing the recommendations.

Visit CDC’s Frequently Asked Questions webpage to find answers to common questions from state, local, and territorial jurisdictions. Although we’re still working on the answers to many of your questions, CDC will continue updating this page as we have more information to share.

You can also use this jurisdiction feedback form to provide feedback and ask questions. We look forward to hearing from you!
