论文摘要
在COVID-19病毒爆发之后，提出了对疾病在不同国家之间传播的简短现象学（描述性，比较）分析。结果表明，感染传播动态目前是美国最明显的（确认的病例目前每2.16天增加每2.16天的翻倍，而增加了两倍的时间趋势），而其他案例最多的国家则显示出不同的价值和趋势。目前，德国每2.28天的死亡人数增加一倍，法国2.56天，瑞士2.57天，法国2.59天，在美国为2.62天，而只有法国和美国目前显示进一步的加速度（降低了两倍的时间）。
In the wake of the COVID-19 virus outbreak, a brief phenomenological (descriptive, comparative) analysis of the dynamics of the disease spread among different countries is presented. Results indicate that the infection spread dynamics is currently the most pronounced in the USA (confirmed cases are currently doubling every 2.16 days, with a decreasing doubling time tendency), while other countries with the most confirmed cases show different values, and tendencies. The reported number of deaths is currently doubled every 2.28 days in Germany, 2.56 days in France, 2.57 days in Switzerland, 2.59 days in France, and 2.62 days in USA, while only France and USA are currently exhibiting further acceleration (diminishing doubling time).
