Epidemic spreading in heterogeneous networks has attracted great interest in recent years. To capture the significant effect of residence of individuals on epidemic spreading, we consider herein a simple susceptible-infected-susceptible model with random waiting time in heterogeneous networks. We provide the analytical dynamical expressions for the time evolution for infected individuals and find a fractional memory effect of power-law waiting time on anomalous epidemic spreading. This work provides new quantitative insights in describing contagion processes and could help model other spreading phenomena in social and technological networks.

在异构网络中流行的异常流行病。

近年来,异构网络中的流行病传播引起了人们极大的兴趣。为了捕获个人居住对流行病传播的重大影响,我们在这里考虑一个简单的易感性感染易感性模型,该模型在异构网络中具有随机的等待时间。我们提供了受感染个体时间演变的动力学分析表达式,并发现幂律等待时间对异常流行病传播的部分记忆效应。这项工作为描述传染过程提供了新的定量见解,并可能有助于对社会和技术网络中其他传播现象进行建模。
