流行病学中非药物干预的几何方法

Geometric approach for non pharmaceutical interventions in epidemiology

Laurent Evain, Jean-Jacques Loeb

摘要:

各种非药物干预措施已得到解决,以尽量减少COVID-19爆发的负担。我们建立了一个框架来分析非药物干预的动态,以区分导致客观科学改进的缓解措施和基于政治和科学考虑的缓解措施。我们在这个框架内分析了两种可能的策略。也就是说,我们考虑由卫生系统有限资源驱动的缓解措施,以及在不同时刻应用一套恒定措施的缓解措施。我们描述了这些情况下的最佳干预措施。我们的方法是数学的,涉及微分系统,它是定性的和几何的,而不是计算的。随着对这些情况的分析,我们收集了几个结果,这些结果本身可能是有用的,特别是在地面上,当变量是不知道的实时。

英文摘要:

Various non pharmaceutical interventions have been settled to minimise the burden of the COVID-19 outbreak. We build a framework to analyse the dynamics of non pharmaceutical interventions, to distinguish between mitigations measures leading to objective scientific improvements and mitigations based on both political and scientific considerations. We analyse two possible strategies within this framework. Namely, we consider mitigations driven by the limited resources of the health system and mitigations where a constant set of measures is applied at different moments. We describe the optimal interventions for these scenarios. Our approach is mathematical and involves sir differential systems, it is qualitative and geometrical rather than computational. Along with the analysis of these scenarios, we collect several results that may be useful on their own, in particular on the ground when the variables are not known in real time.
