We present a differential equations model in which contagious disease transmission is affected by contagious fear of the disease and contagious fear of the control, in this case vaccine. The three contagions are coupled. The two fears evolve and interact in ways that shape distancing behaviour, vaccine uptake, and their relaxation. These behavioural dynamics in turn can amplify or suppress disease transmission, which feeds back to affect behaviour. The model reveals several coupled contagion mechanisms for multiple epidemic waves. Methodologically, the paper advances infectious disease modelling by including human behavioural adaptation, drawing on the neuroscience of fear learning, extinction and transmission.

我们提出了一个微分方程模型，其中传染病的传播受到对疾病的传染性恐惧和对控制的传染性恐惧的影响，在这种情况下是疫苗。这三种传染病是耦合的。这两种恐惧以影响疏远行为、疫苗接种和放松的方式演变和相互作用。反过来，这些行为动态可以放大或抑制疾病传播，进而影响行为。该模型揭示了多个流行波的几种耦合传染机制。在方法论上，该论文通过引入人类行为适应，利用恐惧学习、灭绝和传播的神经科学来推进传染病建模。
