复杂网络上带直接免疫及传染媒介的S IRS模型
AN SIRS MODEL WITH DIRECT IMMUNISATION AND INFECTIVE MEDIUM ON COMPLEX NETWORKS
摘要
Abstract
When simulating practical system with complex networks,it usually uses the infection models with either direct immunisation orinfective medium.These models only focus on the factor of certain aspect in the practical system.Aiming at this insufficiency,the paper pro-poses a novel SIRS (susceptible infected removed susceptible)epidemic model,i.e.an SIRS model with infective medium and direct im-munisation.By using mean-field theory,we establish a corresponding ordinary differential equation system,and discuss the transmission dy-namics behaviour of the system.Research results show that there is a limited transmission threshold in the model under the condition of uni-form networks,and the infective medium can also accelerate the disease spread,and the transmission threshold of the model in non-uniformnetworks is mainly related to the topology of the networks.关键词
