论文摘要
已经开发了许多数学流行病学模型,以说明诸如疫苗接种或隔离的控制措施。但是,Covid-19带来了前所未有的社会距离措施,面临着如何以可以解释数据但避免过度适合参数推断的方式来包括这些措施的挑战。我们在这里开发了一个简单的时间依赖模型,其中引入了类似于系统生物学基因表达控制的粗粒细胞模型的社会距离效应。我们采用我们的方法来理解河北(武汉)和其他中国大陆省之间观察到的19009感染和死亡人数的巨大差异。我们发现,这些不直觉的数据可以通过频道和湖北部和其他省份之间的可传播性,有效保护和检测效率的差异来解释。更普遍地,我们的结果表明,区域差异可能会大大影响感染爆发。获得的结果证明了我们开发的方法可以直接从公开可用的数据中提取关键感染参数的适用性,以便可以将其全球应用于许多国家 /地区的Covid-19爆发。总体而言,我们表明,不常见策略的应用,例如分子系统生物学研究到数学流行病学的方法和方法,可能会大大提高我们对COVID-19和其他传染病的理解。
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.
