Design of public safety and health system in the context of epidemic

Designing the public safety and health system in the context of epidemic is critical to public safety. This paper conducts modeling and analysis on the basis of the SIR model, establishes the “big prevention” system and the “grassroots” grid system. The purpose is to improve the response speed of the public safety and health system respectively, and play a reverse detection role on the epidemic data reported by the grassroots and reduce the possibility of under-reporting. The big data and computer network are used in the public safety and health system, which is the main tool of information transmission and analysis of the public safety and health system. Finally, the feasibility of the design is demonstrated by a case study.
