摘要
研究了无尺度网络中的具有隔离项的SIQR传染病模型,利用平均场理论对疾病的传播进行了研究分析,经过计算得到了疾病传播的临界条件R0,证明了最终疾病的消失或者爆发是由临界值来决定的。然后,通过计算机仿真表明降低感染状态的感染率和提高染病节点的隔离率可以有效地控制该类传染病的传播。
A SIQR epidemic model with quarantine in scale free complex networks is investigated,by means of the mean-field theory,the spread of the disease is studied.Threshold R0 is obtained by calcula tion,and it is proved that the disappearance or eruption of the disease is determined by threshold R0..Computer simulation indicates that reducing infection rate and improving the isolation rate of infected nodes can effectively control the spread of infectious diseases.
