COVID-19患病率和死亡率趋势:一年回顾

Trends in COVID-19 prevalence and mortality: a year in review

Nick James, Max Menzies

摘要:

本文介绍了研究2020年50个受影响最严重国家的COVID-19病例和死亡变化动态的新方法。首先,我们分析滚动死亡率的轨迹和转折点,以了解疾病在哪些时候最致命。我们展示了死亡率轨迹的五个特征类,并确定随着时间的推移死亡率趋势的结构相似性。接下来,我们引入一类\emph{virulence matrices}来研究全球范围内COVID-19病例和死亡的演变。最后,我们引入\emph{three-way inconsistency analysis}来确定关于三个属性的异常国家:国家的COVID-19病例,死亡和人类发展指数。在这三项指标中,我们发现最不正常的国家是巴基斯坦、美国和阿拉伯联合酋长国。

英文摘要:

This paper introduces new methods to study the changing dynamics of COVID-19 cases and deaths among the 50 worst-affected countries throughout 2020. First, we analyse the trajectories and turning points of rolling mortality rates to understand at which times the disease was most lethal. We demonstrate five characteristic classes of mortality rate trajectories and determine structural similarity in mortality trends over time. Next, we introduce a class of \emph{virulence matrices} to study the evolution of COVID-19 cases and deaths on a global scale. Finally, we introduce \emph{three-way inconsistency analysis} to determine anomalous countries with respect to three attributes: countries' COVID-19 cases, deaths and human development indices. We demonstrate the most anomalous countries across these three measures are Pakistan, the United States and the United Arab Emirates.
