[OPHDST] National Notifiable Diseases Surveillance System (NNDSS)

The National Notifiable Diseases Surveillance System (NNDSS) is the nation’s public health surveillance system used to monitor the occurrence and spread of nationally notifiable conditions. Respondents are 60 jurisdictions: public health departments in every U.S. state, New York City, Washington DC, 5 U.S. territories (American Samoa, the Commonwealth of Northern Mariana Islands, Guam, Puerto Rico, and the U.S. Virgin Islands), and 3 freely associated states (the Federated States of Micronesia, the Republic of the Marshall Islands, and the Republic of Palau). NNDSS provides the official source of statistics in the United States for nationally notifiable conditions and CDC is the sole repository for these national, population-based data. Recently the NNDSS platform was modernized and expanded as a low-cost, common portal for collecting information on other conditions. Among the thousands of diseases that affect the health of the population, CDC and the Council of State and Territorial Epidemiologists (CSTE) have prioritized the approximately 120 Nationally Notifiable Conditions as those most important for public health monitoring and response. Changes to NNDSS in this Revision include: 1) Addition of case notification data for non-pestis yersiniosis, injuries related to firearms, and Chagas disease; and 2) Processing a total of 61 new data elements for 2 conditions: Toxoplasmosis and congenital toxoplasmosis The overall burden hours decreased since the last Revision because there were less one-time burdens associated with disease-specific data elements in this Revision
