Research on transmission model of consciousness of prevention and control among the public in major public health emergencies

ABSTRACT

COVID-19 epidemic is a major global public health emergency that rarely happened in a century. China has entered the normal stage of epidemic prevention and control after strenuous struggle. Epidemic prevention and control have been promoted synchronously with economic recovery. It is very important that how to realize the effective transmission for epidemic consciousness of prevention and control in the public at this stage of normalization of the epidemic. For this reason, a transmission dynamic model of consciousness of prevention and control in multiplex social networks formed by multiple channels is firstly established. Model analysis and simulation experiments are carried out to draw that it can make the consciousness of prevention and control transmit among public all the time as long as the proportion of owners with consciousness is above a critical value according to the threshold conditions for distinguishing whether the consciousness propagates. It is difficult to quickly raise consciousness of prevention and control for the public that communicating through a single channel. Online and offline multiple information channels are used in a balanced manner in order to maximize the efficiency of transmission. It can promote the transmission of consciousness of prevention and control as much as possible that scientifically and moderately increasing the number of daily communication. Once the number of public communication through multiple channels exceeds a certain limit, it will reduce the efficiency of transmission for consciousness of prevention and control. © 2021, Editorial Board of Journal of Systems Engineering Society of China.
