：文章阐述了应急响应各阶段情报流的作用，结合新冠肺炎疫情分析了三个应急阶段情报流对疫情防控的精准刻画及疫情全局演变规律的揭示；基于疫情情报流的分析，提出了面向新冠肺炎疫情防控的公共卫生突发事件应急响应情报体系，从疫情防控需求设计了组织架构与功能架构并深度融合了疫情应急响应全程的情报工作。基于文章架构的疫情防控情报体系的理论与方法，结合国家疫情联防联控机制的实践发现情报体系在疫情的应急中发挥了巨大作用和价值。最后面向公共卫生的应急情报研究，提出了进一步突破与落实的方向。

This paper expounds the role of the information flow in each stage of the emergency response, which has to analyzed the accurate description of the information flow in the three emergency stages of the epidemic prevention, and then to reveals the overall evolution of the epidemic situation. Based on the analysis of the epidemic information flow, the paper is proposed the public health emergency response intelligence system for the epidemic prevention., at the same to designed the organizational structure and functional structure from the needs of the epidemic prevention, and in-depth integration of information work throughout the rapid response to emergency of epidemic prevention. The paper is also constructed the theory and method of the epidemic prevention and control information system, combined with the practice of the national epidemic prevention and control mechanism, and the information system has a great role and value in the emergency response to the epidemic. In summary, the research proposes the directions of further breakthrough and implementation for public health emergency information.
