The Health Electronic Surveillance Network (HESN) allows health authorities to collect, analyze, and share public health data to improve outcomes. HESN components include systems for disease investigation, outbreak notification, immunization management, and reporting. HESN provides opportunities for standardized, real-time data and integration with partners, but faces challenges of limited resources, resistance to change, reliability in remote areas. Future priorities for HESN include strengthening active disease surveillance, infection prevention, and decision support systems.
