本文的主要目的是研究COVID-19的传播及其影响传播的相关因素。对中国、韩国、日本、意大利、美国、巴西等6个国家的传播情况进行了定性分析。本文试图检验COVID-19传播的缓解效果和大流行的严重程度。以每日新增确诊病例达到高峰时间和最大下降率衡量缓解效果，以确诊病例占人口比例和死亡率评估大流行严重程度。根据缓解效果、大流行严重程度和死亡率，将六个样本国家分为四类：缓解效果高vs大流行严重程度低、缓解效果中等vs大流行严重程度低、缓解效果高vs大流行严重程度高、缓解效果低vs大流行严重程度高。结果发现，韩国和中国的缓解效果相对较高，大流行严重程度较低，而美国和巴西则相反。本文认为，病毒检测与接触者追踪、严格实施封锁、公众合作对减少COVID-19传播具有重要作用。
The major purpose of this paper was to examine the transmission of COVID-19 and the associated factors that affect the transmission. A qualitative analysis was conducted by comparing the COVID-19 transmission of six countries: China, Korea, Japan, Italy, the USA, and Brazil. This paper attempted to examine the mitigation effectiveness for the transmission of COVID-19 and the pandemic severity. Time to reach the peak of daily new confirmed cases and the maximum drop rate were used to measure the mitigation effectiveness, while the proportion of confirmed cases to population and the mortality rate were employed to evaluate the pandemic severity. Based on the mitigation effectiveness, the pandemic severity, and the mortality rate, the six sample countries were categorized into four types: high mitigation effectiveness vs. low pandemic severity, middle mitigation effectiveness vs. low pandemic severity, high mitigation effectiveness vs. high pandemic severity, and low mitigation effectiveness vs. high pandemic severity. The results found that Korea and China had relatively higher mitigation effectiveness and lower pandemic severity, while the USA and Brazil had the opposite. This paper suggests that viral testing together with contacts tracing, strict implementation of lockdown, and public cooperation play important roles in achieving a reduction in COVID-19 transmission.
