研究新型冠状病毒病2019 （COVID-19）的时空传播特征和传播过程，对了解疫情发展，建立国际防控合作具有重要的现实意义。本文以中美累计确诊病例数、每日确诊病例数和累计死亡人数为指标，比较两国新冠肺炎的传播途径、爆发时间和应对策略。结果表明：第一，中美两国新冠肺炎疫情均呈现为期6周的初始阶段。在中国，新冠肺炎疫情于1月底爆发。它只持续了很短的时间，在6-8周内几乎完全被控制住了。但新冠肺炎疫情于3月初在美国爆发，目前仍处于高峰或后高峰阶段。第二，在中国，新冠肺炎疫情从武汉开始扩散到湖北省其他地区，然后扩散到全国，呈以武汉市为中心的“+”型传播。重要的是，中国疫情集中度高，没有出现全国性疫情。相比之下，美国的新冠肺炎疫情首先在纽约和东西海岸传播，后来在全国范围内蔓延。第三，两国在早期阶段（约6周）缺乏应急计划，阻碍了COVID-19的预防。3月初，中国采取积极高压防控措施，疫情防控基本得到控制。然后中国逐渐恢复了商业和生产活动。不幸的是，美国政府错过了控制疫情的最佳时机。面对经济复苏和新冠肺炎疫情之间的选择，美国过早取消了隔离和限制措施。新冠肺炎疫情继续在全国蔓延，到处开花，仍然没有消退的迹象。
Investigating the spatio-temporal transmission features and process of novel coronavirus disease 2019 (COVID-19) mitigation strategies are of great practical significance to understand the development of COVID-19 and establish international cooperation for prevention and control. In this paper, the cumulative number of confirmed cases, number of confirmed cases per day and cumulative number of deaths, were used to compare transmission paths, outbreaks timelines, and coping strategies of COVID-19 in China and the US. The results revealed that: first, the COVID-19 outbreaks in both China and the US exhibited a 6-week initiation stage. In China, the COVID-19 erupted in late January. It lasted only a short period of time and was almost completely contained within 6–8 weeks. But the COVID-19 erupted in early March in the US and was still in the peak or post-peak stage. Second, in China, the COVID-19 emerged in Wuhan and spread to other regions of Hubei Province and then nationwide, exhibiting a cross(“+”)-shaped of spread with Wuhan city as the center. Importantly, the COVID-19 in China had a large concentration and there were no national outbreaks. In contrast, the COVID-19 in the US first spread through New York and the western and eastern coasts but has since emerged throughout the entire country. Third, the lack of emergency response planning in both countries in the early stage (about 6-week) hampered COVID-19 prevention. However, actively high-pressure prevention and control measures were used to basically control COVID-19 in early March in China. And then China has gradually resumed business and production activities. Unfortunately, the US government missed the best opportunity to contain the epidemic. Faced with the choice between economic recovery and coronavirus containment, the US removed the quarantine and restriction measures too early. The COVID-19 is continuing to spread in the country and blossom everywhere, still showing no signs of receding.
