North Carolina Electronic Disease Surveillance System (NC EDSS)

NC EDSS, the North Carolina Electronic Disease Surveillance System, is a component of the Centers for Disease Control and Prevention (CDC) initiative to move states to web-based health surveillance and reporting systems. NC EDSS is also part of the Public Health Information Network (PHIN). The electronic system replaced a patchwork of smaller disease-specific surveillance systems and paper-based reporting.

NC EDSS is used by the North Carolina Department of Health and Human Services, Division of Public Health, the state's 86 local and multi-county district health departments (LHDs), and eight HIV/STD Regional Offices. Laboratories also report electronically to NC EDSS.
