National Outbreak Reporting System (NORS)

NORS - National Outbreak Reporting System logo

Waterborne disease and outbreak reporting to the Waterborne Disease and Outbreak Surveillance System (WBDOSS) transitioned from a paper-based system to the electronic National Outbreak Reporting System (NORS) in 2009. NORS is a web-based platform used by local, state, and territorial health departments in the United States to report all waterborne and foodborne disease outbreaks and enteric disease outbreaks transmitted by contact with environmental sources, infected persons or animals, or unknown modes of transmission to CDC.

NORS Dashboard is a web-based tool for accessing data from CDC’s National Outbreak Reporting System (NORS).

Nearly 100,000 people in the United States get sick from foodborne, waterborne, and enteric illness outbreaks each year, according to information reported in NORS. NORS Dashboard makes national surveillance data from outbreaks more accessible to anyone who wants to learn more about what causes these outbreaks, how often and where they occur.
