Simulation Study On The Spread Of Emerging Infectious Disease Considering Consciousness Factors

In the development of human society,infectious diseases increasingly affect human physical and mental health.How to accurately simulate the spread of infectious diseases among people and analyze the relevant factors affecting the spread of infectious diseases has become an important issue in the field of public health management and Cyberspace Security.In recent years,emerging infectious diseases occur frequently,and the emerging infectious diseases have "unprecedented" particularity,which requires residents to "actively isolate" and reduce the possibility of contact with others.Consciousness determines behavior,and the premise of conscious "isolation" is to understand emerging infectious disease.Therefore,it is of great practical significance to study the impact of the spread of disease awareness on the spread of infectious diseases.According to the different prevention and control measures of emerging infectious diseases,this study divides the research situation into two categories:abnormal epidemic prevention and control and normalization of epidemic prevention and control,and studies how the spread of disease awareness affects the spread of infectious diseases separately.By exploring the research background and purpose,clarify the research problems,and analyze the research status of relevant theories,determine the research innovation of this paper,and lay a theoretical foundation for follow-up research.By combing the relevant theories and models,it provides theoretical support for the study of the spread of emerging infectious diseases considering the factor of consciousness.Then,determine the description framework of the dual transmission of infectious disease transmission and disease consciousness diffusion,clarify the network structure of the dual transmission process,and construct the disease transmission model and consciousness diffusion model respectively.Based on the experimental design,the experiment is carried out by using agent-based modeling technology on Repast Simphony 2.7 development platform,and the experimental data are sorted and analyzed by R software.According to the experimental results,the prevention and control suggestions for practical reference are given,finally,the limitations of this study are discussed and the future research is prospected.The experimental results show that the five control variables will affect the spread of infectious diseases,and each disease transmission parameter does not affect the results alone,but interacts with each other to affect the spread of diseases.Single exposure infection rate,instant recovery rate and mortality all directly affect the spread of infectious diseases.Single exposure awareness acquisition rate and forgetting rate also affect the explained variables(peak proportion of infected persons,cumulative proportion of infected persons,proportion of rehabilitated persons and proportion of dead persons)to a certain extent.Awareness acquisition rate has a linear negative relationship with the explained variables,while awareness forgetting rate has a linear positive relationship with the explained variables.No matter what epidemic prevention and control situation,reducing the infection rate and improving the rehabilitation rate can weaken the spread of the disease,improve the awareness acquisition rate or reduce the awareness forgetting rate,make the conscious susceptible and infected people actively isolate,and play the role of consciousness in correcting the parameters of disease transmission.However,the difference is that the diffusion of consciousness plays a greater role in the normalized situation,which can quickly reduce the limit pressure and process pressure of disease transmission,and the final recovery ratio and death ratio are reduced accordingly.
