The Electronic Disease Notification System is an electronic system used to notify state and local public health jurisdictions about diseases and disease outbreaks occurring among refugees and immigrants entering the United States. The system has a module to track tuberculosis and other quarantinable diseases in refugees and immigrants. The CDC uses the system to electronically notify health departments of arriving refugees and immigrants with Class A and Class B quarantinable conditions, provide an electronic communication system for health departments to notify each other of persons with tuberculosis conditions who change jurisdictions, and provide health departments with an electronic system to record and evaluate the outcome of domestic follow-up examinations.
