美国的COVID-19:轨迹和第二次激增行为

COVID-19 in the United States: Trajectories and second surge behavior

Nick James, Max Menzies

摘要:

本文介绍了一个用于确定美国COVID-19病例第二次激增行为的数学框架。在这个框架内,灵活的算法方法为每个状态选择一组转折点,计算它们之间的距离,并确定每个状态是否处于(或超过)第一次或第二次浪涌。然后,适当的归一化时间序列之间的距离被用来进一步分析每月的基础上的情况下的轨迹之间的关系。我们的算法显示,31个州正在经历第二次激增,而10个最大的州中有4个仍处于第一次激增,病例数从未减少。这一分析有助于突出最成功和最不成功的国家应对COVID-19。

英文摘要:

This paper introduces a mathematical framework for determining second surge behavior of COVID-19 cases in the United States. Within this framework, a flexible algorithmic approach selects a set of turning points for each state, computes distances between them, and determines whether each state is in (or over) a first or second surge. Then, appropriate distances between normalized time series are used to further analyze the relationships between case trajectories on a month-by-month basis. Our algorithm shows that 31 states are experiencing second surges, while 4 of the 10 largest states are still in their first surge, with case counts that have never decreased. This analysis can aid in highlighting the most and least successful state responses to COVID-19.
