Research on Society Risk Evolution Mechanism and Counter Measures in Severe Emergency Infectious Disease — in the Case of H7N9 Avian Influenza

Abstract

In this paper, the evolution and control of society risks caused by severe emergency infectious disease will be analyzed and studied. Firstly, the evolution chain of society risks caused by severe emergency infectious disease is constructed to analyze the evolution rule of society risks and identify the essential factors in counter measures. Then, the system dynamics model is established and employed to simulate the effects of society risk control with various countermeasures. Finally, based on the simulation results, a conclusion is drawn: improving medical treatment capacity, strengthening quarantine level under epidemic situation and enhancing the effective ness of dealing with public opinions are effective in controlling society risks. Especially when the three aspects mentioned above are promoted at the same time, the society risk control can achieve a more notable effect.
