Abstract

Major public health emergencies are characterized by their hazardous nature, widespread impact, and interconnected effects. These events typically generate multi-faceted and cross-regional damages to socioeconomic systems and public welfare, potentially inducing multi-tiered systemic risks that may escalate into public crises. Building on the disaster lifecycle theory, this study employs a dual-risk analytical framework to distinguish between primary risks (direct consequences) and derivative risks (emerging from interactions between event-specific factors and external environments). Through systematic analysis of risk evolution patterns, we propose an integrated prevention system featuring: (1) a three-stage defense mechanism (identification-assessment-early warning) and (2) a comprehensive governance framework covering emergence, diffusion, outbreak, and recession phases. The research outcomes provide both theoretical insights and practical strategies for managing social risks in public health crises. Keywords: major public health emergencies; social risk; evolutionary mechanism; risk prevention and control.
