摘要:

数学流行病学中的一些模型已经被开发出来,以解释诸如疫苗接种或检疫等控制措施。然而,COVID-19带来了前所未有的社交距离措施,挑战在于如何以一种既能解释数据又能避免在参数推断中过度拟合的方式纳入这些措施。在这里,我们开发了一个简单的时间依赖性模型,社会距离效应类似于系统生物学中基因表达控制的粗粒度模型。我们应用我们的方法来了解湖北(武汉)与中国内地其他省份之间COVID-19感染和死亡人数的巨大差异。我们发现,这些不直观的数据可以通过湖北省和其他省份之间的传播率,有效保护和检测效率差异的相互作用来解释。更一般地说,我们的研究结果表明,地区差异可能会大大塑造感染爆发。所获得的结果证明了我们开发的方法的适用性,可以直接从医学上可用的数据中提取关键感染参数,以便它可以在全球范围内应用于许多国家的COVID-19爆发。总的来说,我们表明,应用不常见的策略,如从分子系统生物学研究到数学流行病学的方法和途径,可能会大大促进我们对COVID-19和其他传染病的理解。

英文摘要:

A number of models in mathematical epidemiology have been developed to account for control measures such as vaccination or quarantine. However, COVID-19 has brought unprecedented social distancing measures, with a challenge on how to include these in a manner that can explain the data but avoid overfitting in parameter inference. We here develop a simple time-dependent model, where social distancing effects are introduced analogous to coarse-grained models of gene expression control in systems biology. We apply our approach to understand drastic differences in COVID-19 infection and fatality counts, observed between Hubei (Wuhan) and other Mainland China provinces. We find that these unintuitive data may be explained through an interplay of differences in transmissibility, effective protection, and detection efficiencies between Hubei and other provinces. More generally, our results demonstrate that regional differences may drastically shape infection outbursts. The obtained results demonstrate the applicability of our developed method to extract key infection parameters directly from publically available data so that it can be globally applied to outbreaks of COVID-19 in a number of countries. Overall, we show that applications of uncommon strategies, such as methods and approaches from molecular systems biology research to mathematical epidemiology, may significantly advance our understanding of COVID-19 and other infectious diseases.
