By the end of May 2020, all states in the US have eased their COVID-19 mitigation measures. Different states adopted markedly different policies and timing for reopening. An important question remains in how the relaxation of mitigation measures is related to the number of casualties. To address this question, we compare the actual data to a hypothetical case in which the mitigation measures are left intact using a projection of the data from before mitigation measures were eased. We find that different states have shown significant differences between the actual number of deaths and the projected figures within the present model. We relate these differences to the states different policies and reopening schedules. Our study provides a gauge for the effectiveness of the approaches by different state governments and can serve as a guide for implementing best policies in the future. According to the Pearson correlation coefficients we obtained, the face mask mandate has the strongest correlation with the death count than any other policies we considered.
截至 2020 年 5 月底，美国所有州都已放宽了 COVID-19 缓解措施。不同的州采取了截然不同的重新开放政策和时间。一个重要的问题仍然是缓解措施的放松与伤亡人数之间的关系。为了解决这个问题，我们将实际数据与一个假设情况进行了比较，即在使用缓解措施放宽前的数据进行预测的情况下，缓解措施保持不变。我们发现，不同的州在实际死亡人数和本模型中的预测数字之间存在显著差异。我们将这些差异与各州不同的政策和重新开放时间表联系起来。我们的研究为不同州政府的措施的有效性提供了一个衡量标准，并可以为未来实施最佳政策提供指导。根据我们获得的皮尔逊相关系数，与我们考虑的任何其他政策相比，口罩强制令与死亡人数的相关性最强。
