In this work, we address a multicoupled dynamics on complex networks with tunable structural segregation. Specifically, we work on a networked epidemic spreading under a vaccination campaign with agents in favor and against the vaccine. Our results show that such coupled dynamics exhibits a myriad of phenomena such as nonequilibrium transitions accompanied by bistability. Besides we observe the emergence of an intermediate optimal segregation level where the community structure enhances negative opinions over vaccination but counterintuitively hinders—rather than favoring—the global disease spreading. Thus our results hint vaccination campaigns should avoid policies that end up segregating excessively antivaccine groups so that they effectively work as echo chambers in which individuals look to confirmation without jeopardizing the safety of the whole population.

社交网络时代的抗病毒运动与流行病传播：非单调效应、双稳态和网络隔离

在这项工作中，我们解决了具有可调结构隔离的复杂网络上的多耦合动力学问题。具体来说，我们致力于在疫苗接种运动下传播网络流行病，代理人支持和反对疫苗。我们的结果表明，这种耦合动力学表现出无数现象，例如伴随双稳态的非平衡转变。此外，我们观察到中间最优隔离水平的出现，其中社区结构增强了对疫苗接种的负面看法，但违反直觉地阻碍了——而不是支持——全球疾病的传播。
