摘要

一年半以来,世界受到新冠肺炎大流行的严重影响。然而,新冠肺炎病例在各国的分布并不均匀;少数国家,特别是高收入国家受到的打击比经济状况不佳的国家更为严重。造成这种不对称分布的原因尚不清楚。在这项工作中,我们研究了截至2021年6月18日新冠肺炎发病率在各国经济状况方面的全球分布不均衡。随后,我们试图确定新冠肺炎病例不平等背后的主要潜在因素。我们的分析表明,物理连接和冠状病毒的传播是新冠肺炎病例在不同国家不同程度不平等传播的主要原因。我们发现,新冠肺炎感染和死亡病例在规定参数方面得到了幂律的很好描述。

A Quest for the Origin of the Uneven Spread of Covid-19 Cases
For more than one and a half years now, the world is highly impacted by the Covid-19 pandemic. The Covid-19 cases are, however, not evenly distributed across the countries; a few countries, particularly high-income countries have been hit harder than the countries of weak economic condition. The reasons for such an asymmetrical distribution are not clearly understood yet. In this work, we have examined the unevenness of global distribution of Covid-19 incidences till 18th June 2021 in terms of the economic condition of countries. Subsequently, we have tried to identify the main underlying factors behind unequal Covid-19 cases. Our analysis suggests that the physical connectivity and the diffusion of coronavirus are the main causes of the different unequal spread of Covid-19 cases in different countries. We find that the Covid-19 infected and death cases are well described by a power law in terms of the stated parameters.
