具有时滞的复杂网络中的传染病传播

Epidemic spreading with time delay in complex networks

Xin-Jian Xu, Hai-Ou Peng, Xiao-Mei Wang, Ying-Hai Wang

摘要:

提出了一个改进的小世界无标度复杂网络\emph{susceptible-infected-susceptible}(SIS)模型,研究了在传染阶段引入时滞的传染病传播问题。考虑到网络的拓扑结构,研究了传染过程中的一致时滞和度依赖时滞。我们发现,时滞的存在将促进网络中传染病的爆发和流行。

英文摘要:

We present a modified \emph{susceptible-infected-susceptible} (SIS) model on complex networks, small-world and scale-free, to study epidemic spreading with the effect of time delay which is introduced to the infected phase. Considering the topology of the network, both uniform and degree-dependent delays are studied during the contagion process. We find that the existence of time delay will enhance both outbreaks and prevalence of infectious diseases in the network.
