复杂网络上具有免疫率的传染病传播

Epidemic spreading with immunization rate on complex networks

Shinji Tanimoto

摘要:

我们调查疾病,计算机病毒或信息在复杂网络上的传播,以及预防或控制传播的免疫策略。在不能实现全民免疫、免疫效果不理想的情况下,需要进行有免疫率的靶向免疫。在这种情况下,我们计算了SIR和SIS流行病模型的流行病阈值。结果表明,在无标度网络中,只有当免疫率等于1时,目标免疫才是有效的。我们在这里分析传染病传播的有向复杂网络,但类似的结果也适用于无向的。

英文摘要:

We investigate the spread of diseases, computer viruses or information on complex networks and also immunization strategies to prevent or control the spread. When an entire population cannot be immunized and the effect of immunization is not perfect, we need the targeted immunization with immunization rate. Under such a circumstance we calculate epidemic thresholds for the SIR and SIS epidemic models. It is shown that, in scale-free networks, the targeted immunization is effective only if the immunization rate is equal to one. We analyze here epidemic spreading on directed complex networks, but similar results are also valid for undirected ones.
