Abstract

This study evaluates COVID-19 prevention and control policies. Based on the simulation, we compare the effects of two major policies: contact restriction and active treatment. Through regression and cluster analysis, we classified 169 countries and regions in the world into 10 groups, among which five groups accounted for the major proportion: the ones with the labels “CHN (China) mode,” “SE (South Europe) mode,” “ENE-SSA (East & North Europe and Sub-Saharan Africa) mode,” “US (United States) mode,” and “DEU (Germany) mode”). Differences in the effects of the prevention and control of COVID-19 in typical countries in each mode are comprehensively investigated. The conclusions of this study can be summarized as follows: First, contact restriction outperforms active treatment in curbing the spread of COVID-19. Second, “CHN mode” ranks the highest level of epidemic control and emphasizes epidemic prevention and control more than economic stimulus, which is the opposite of the “US mode”. Regression analysis reveals that the differences in epidemics worldwide are caused by policy differences among modes.

新型冠状病毒肺炎防控模式及效果分析

本研究评估了新冠肺炎防控政策。在模拟的基础上，我们比较了两种主要政策的效果：限制接触和积极治疗。通过回归和聚类分析，我们将世界上169个国家和地区分为10组，其中5组占主要比例：标签为“CHN（中国）模式”、“SE（南欧）模式”和“ENE-SSA（东欧和北欧及撒哈拉以南非洲）模式”的国家和地区、“US（美国）模式”以及“DEU（德国）模式”。全面调查了不同模式下典型国家新冠肺炎防控效果的差异。本研究的结论可以总结如下：首先，在遏制新冠肺炎传播方面，限制接触优于积极治疗。第二，“CHN模式”是疫情控制的最高级别，比经济刺激更强调疫情防控，这与“美国模式”相反。回归分析表明，全球疫情的差异是由不同模式的政策差异引起的。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
