地方和全球网络连接对协同流行病的影响

Effects of local and global network connectivity on synergistic epidemics

David Broder-Rodgers, Francisco J. Pérez-Reche, Sergei N. Taraskin

摘要:

在具有无限和有限范围重连的格点模型(小世界和类小世界模型)中,研究了局部和全局连通性对协同的易感-感染-消除流行病传播的影响。在一个简单的模型中发现了几种效应,并得到了分析上的支持:(1)在具有高局部连通性的网络上,通过强建设性协同作用,重新连接增强了对流行病的抵御能力;(2)在具有任意局部连通性的网络上,通过破坏性或弱建设性协同作用,重新连接增强了流行病的传播;(3)在具有低局部连通性的网络中,独立于协同作用,重新连接增强了流行病的传播。

英文摘要:

The effects of local and global connectivity on the spread of synergistic susceptible-infected-removed epidemics were studied in lattice models with infinite- and finite-range rewiring (small-world and small-world-like models). Several effects were found numerically and supported analytically within a simple model: (i) rewiring enhanced resilience to epidemics with strong constructive synergy on networks with high local connectivity; (ii) rewiring enhanced spread of epidemics with destructive or weak constructive synergy on networks with arbitrary local connectivity; (iii) rewiring enhanced spread of epidemics, independent of synergy, in networks with low local connectivity.
