Abstract: Public health emergency management is directly related to public health, social stability, and national security. Currently, public health emergency management in China faces challenges such as imperfect cross-departmental collaboration models, generally insufficient early identification capabilities for public health emergencies, and the ineffective role of information technology support. This article focuses on the needs of national public health emergency management, from the three perspectives of risk management, emergency management, and crisis management, and organically integrates information technology with key aspects such as early identification, early warning and prediction, risk assessment, emergency response, and decision-making management, to construct a smart public health emergency management platform for China. This platform aims to provide information technology support for multi-point monitoring, comprehensive early warning, decision-making management, as well as business collaboration and data sharing across multiple departments and agencies in public health emergency management.
