Division of Notifiable Diseases and Healthcare Information
Advancing Public Health Surveillance Through Science and Collaboration
CDC's Division of Notifiable Diseases and Healthcare Information (DNDHI) helps protect the health of the U.S. population by rapidly identifying and monitoring disease outbreaks and harmful health effects of hazardous conditions and by tracking outbreaks and adverse health effects over time. This information is provided to national, state, and local public health programs for their use in planning and implementing programs to prevent and control disease and injury.
Within CDC, DNDHI leads the integration of CDC's statistical, epidemiologic, and informatics methods for public health surveillance and evaluation. DNDHI works closely with federal, state, and local public health partners to support and improve timely and efficient collection, sharing, and analysis of healthcare and public health information.
By bringing together the National Notifiable Diseases Surveillance System (NNDSS) and BioSense program, DNDHI helps create administrative efficiencies for CDC, improves CDC program collaboration, and strengthens CDC's partnerships with federal, state, and local public health authorities and others.
