Abstract
OBJECTIVES: To present the system capabilities of the restructured Infectious Disease Information System and Big Data Platform, aimed at improving the speed and efficiency of the response to infectious diseases. METHODS: Following the coronavirus disease 2019 pandemic, the limitations of existing systems were analyzed. In response, the core values and strategic directions for the new system were established, along with detailed implementation plans. RESULTS: The Infectious Disease Information System, built on unique identification data, enhanced data accuracy and usability by linking all phases of the infectious disease response to public information systems. Standardized reporting formats have unified analytical frameworks for various diseases. In addition, statistical production and customized analysis are supported through the Infectious Disease Big Data Platform and flexibility is secured by migrating to the National Information Resources Service to ensure stable processing of large-scale information. CONCLUSIONS: By standardizing and integrating disease surveillance and control data, the proposed system enables timely and accurate responses to infectious diseases. It is expected to function as essential infrastructure for future pandemic preparedness and enhanced infectious disease management.
