Development of Early Warning System for Public Health Emergencies in China: Focus on SARS, H7N9, COVID-19

Abstract

As the number of public health emergencies increases in China, the construction of emergency management is becoming more and more eager, especially the dissemination and control of COVID-19 is the most important issue in emergency management. The early warning system of public health emergencies has become one of the hot spots. China's emergency management system has now built a set of its own efficient emergency management mechanism for public health emergencies, but the perfect early warning mechanism for public health emergencies can accurately predict the direction of the development of the event before the event occurs, can avoid suffering, avoid wasting public resources, and invest more funds in other emergencies. From this point of view, China's public health emergency warning mechanism is growing in the confrontation, making China's view from heavy governance slowly firm to heavy warning. At present, China's early warning system has developed to a certain extent, but there are still shortcomings, such as: the unreasonable subject of early warning, the lag of early warning standards, the scope of monitoring subject is not wide enough and so on. This paper will analyze the changes of China's early warning system in the past 20 years through literature analysis and case analysis, and further study how to improve the early warning system of public health emergencies.
