电晕大流行成本的遏制效率和控制策略

Containment efficiency and control strategies for the Corona pandemic costs

Claudius Gros, Roser Valenti, Lukas Schneider, Kilian Valenti, Daniel Gros

摘要:

新型冠状病毒(COVID-19)的迅速传播使政策制定者面临衡量遏制策略有效性的问题,平衡公共卫生考虑与社交距离措施的经济成本。我们引入了一个修改后的流行病模型,我们命名为受控SIR模型,其中的疾病繁殖率动态演变的政治和社会的反应。给出了一个解析解。该模型再现了超过疫情第一个高峰的大量地区和国家的官方COVID-19病例数。从现场数据中提取一个无偏反馈参数,并用于制定衡量遏制策略效率的指数(CEI指数)。给出了一系列国家的CEI值。对于受控SIR模型的两个变体,对整个流行病过程中的医疗和社会经济总成本进行了详细估计。成本包括医疗成本、社会距离的经济成本以及挽救生命的经济价值。在合理的参数下,严格的措施比不干涉政策效果更好。基于当前病例数的战略导致的总成本大大高于基于该流行病总体历史的战略。

英文摘要:

The rapid spread of the Coronavirus (COVID-19) confronts policy makers with the problem of measuring the effectiveness of containment strategies, balancing public health considerations with the economic costs of social distancing measures. We introduce a modified epidemic model that we name the controlled-SIR model, in which the disease reproduction rate evolves dynamically in response to political and societal reactions. An analytic solution is presented. The model reproduces official COVID-19 cases counts of a large number of regions and countries that surpassed the first peak of the outbreak. A single unbiased feedback parameter is extracted from field data and used to formulate an index that measures the efficiency of containment strategies (the CEI index). CEI values for a range of countries are given. For two variants of the controlled-SIR model, detailed estimates of the total medical and socio-economic costs are evaluated over the entire course of the epidemic. Costs comprise medical care cost, the economic cost of social distancing, as well as the economic value of lives saved. Under plausible parameters, strict measures fare better than a hands-off policy. Strategies based on current case numbers lead to substantially higher total costs than strategies based on the overall history of the epidemic.
