About

The National Notifiable Diseases Surveillance System (NNDSS) is a collaborative nationwide surveillance initiative operated by the CDC and the Council of State and Territorial Epidemiologists (CSTE). Through NNDSS, public health agencies across 50 states, five territories, and two independent jurisdictions share weekly provisional data on approximately 120 designated infectious diseases and conditions of public health concern, including hepatitis, Legionellosis, measles, and pertussis.

Through Fibric, an operator references weekly notifiable disease incident rates by state, proposing proactive occupational health reviews, Legionella environmental water testing schedules, and infectious exposure notifications across corporate operations.

This is a reference listing. It documents what Fibric would read from National Notifiable Diseases Surveillance System (NNDSS) and what it could propose, based on the publisher's published interfaces. Fibric builds it under a managed deployment when you request it; selecting it here installs nothing.

Inputs

  • Weekly provisional case counts of approximately 120 nationally notifiable infectious diseases and conditions
  • State and territory jurisdictional distribution tables tracking disease incidence across epidemiological calendar weeks
  • Historical cumulative year-to-date case comparisons against prior calendar year baseline metrics
  • Surveillance indicators for high-consequence bacterial, viral, vector-borne, and waterborne pathogens
  • Socrata Open Data API (SODA) endpoints and CSV tables published on data.cdc.gov

Proposed actions

Read-only. This feed informs operators; it changes nothing.

Proposed actions are target capabilities. Every action runs propose-first and needs a validated deployment and the appropriate permissions.

What you can build

  • Trigger water system checks upon regional Legionellosis spikes

    Monitor state-level Legionellosis notification rates, proposing scheduled water heater inspections and legionella flushes for commercial facilities located in reporting states.

    With Legionella Flush, Compliance Evidence

  • Track state-level infectious outbreaks for workforce health awareness

    Evaluate weekly state notifiable disease trends against field office locations, proposing updated occupational health guidance and safety supplies during localized disease surges.

    With Shift Coverage, Compliance Evidence

Requirements

  • HTTP client capable of querying Socrata SODA REST API endpoints or parsing published CSV tables
  • Temporal reconciliation logic to handle provisional updates across MMWR surveillance calendar weeks
  • Mapping of state jurisdictional counts to internal enterprise facility locations and regions
Authentication
None. NNDSS weekly tables on data.cdc.gov are freely accessible via standard HTTP requests without mandatory API tokens.

Limits

  • Weekly case numbers represent provisional reports subject to state health department revision upon case investigation completion
  • Reporting delays can cause variations in weekly counts based on state local laboratory notification timelines
  • Case definitions adhere to CSTE surveillance standards rather than clinical treatment criteria
