Emergency response to public health incidents is part of the emergency management system for emergencies. Since 2003, this system has been gradually improved, and in this epidemic response, whether the emergency plan has effectively played a role is also a question worthy of reflection.

Stones from other hills may serve to polish the jade of this one. The more mature emergency systems of some countries may be used as mirrors to examine themselves from the perspectives of trigger mechanism, coordination and linkage, and plan execution. Is the hierarchical definition design of public health emergencies too broad and lacks operability? Are there any flaws in the design of the trigger mechanism of the plan, leading to uncertain timing of action? How do different levels participate in the response, and are the boundaries clear? Are there any redundant designs?

Expanded, information communication, big data applications, official and private interactions, and public health emergency supplies are all areas that need to be discussed.
