模拟社会距离对疾病大规模传播的影响

Modeling the effects of social distancing on the large-scale spreading of diseases

Paulo Cesar Ventura, Alberto Aleta, Francisco Aparecido Rodrigues, Yamir Moreno

摘要:

为了遏制新出现的可在人与人之间传播的疾病的传播,通常实施旨在减少人与人之间相互作用的非药物干预措施。后一种措施的一个例子是保持社交距离,这可以是政策驱动的,也可以是由于害怕感染而在人群中自发产生的。然而,如果在人群达到群体免疫力之前取消NPI,病原体的进一步重新引入将导致继发感染。在这里,我们研究了不同的社会距离计划对疾病大规模传播的影响。具体而言,我们概括了集合种群模型,包括在亚种群水平的社会距离机制和模型的短期和长期战略,喂养当地或全球的流行病信息。我们发现,不同的模型成分可能会导致非常不同的结果在不同的亚群。我们的研究结果表明,有没有一个唯一的答案,如果实施和管理本地或全球的竞争措施是否更有效的问题,模型的结果取决于如何充分考虑人类互动的复杂性。

英文摘要:

To contain the propagation of emerging diseases that are transmissible from human to human, non-pharmaceutical interventions (NPIs) aimed at reducing the interactions between humans are usually implemented. One example of the latter kind of measures is social distancing, which can be either policy-driven or can arise endogenously in the population as a consequence of the fear of infection. However, if NPIs are lifted before the population reaches herd immunity, further re-introductions of the pathogen would lead to secondary infections. Here we study the effects of different social distancing schemes on the large scale spreading of diseases. Specifically, we generalize metapopulation models to include social distancing mechanisms at the subpopulation level and model short- and long-term strategies that are fed with local or global information about the epidemics. We show that different model ingredients might lead to very diverse outcomes in different subpopulations. Our results suggest that there is not a unique answer to the question of whether contention measures are more efficient if implemented and managed locally or globally and that model outcomes depends on how the full complexity of human interactions is taken into account.
