论文摘要
2019年 - 新维尔病毒（Covid-19）已影响116个国家（到3月12日），并在118,000多个确认案件中影响了。了解每天影响并评估控制政策有效性的每个国家中感染的传播动态对于我们的进一步行动至关重要。迄今为止，Covid-19的统计数据报告显示，有80％以上的感染患有轻度疾病病例，而大约14％的感染者经历了严重的疾病，大约5％被归类为关键疾病受害者。今天的报告（2020-03-12；准备网站上的每日更新）显示了中国，韩国，意大利和伊朗的Covid-19案件是80932、7869、12462和10075；分别。计算意大利的总案件死亡率（CFR）（2020-03-04），约有7.9％的确认病例去世。与韩国的0.76％（比意大利低10倍）和中国3.8％（比意大利低50％）的速度相比，意大利的CFR太高。有一些有效的政策在案件趋势上产生重大变化。中国和意大利的锁定政策（在11天后观察到的效果），所有不必要的公司的关闭（在5天后观察到的效果），韩国的合并政策以及降低了伊朗的工作时间。
The 2019-Novel-Coronavirus (COVID-19) has affected 116 countries (By March 12) and out of more than 118,000 confirmed cases. Understanding the transmission dynamics of the infection in each country which affected on a daily basis and evaluating the effectiveness of control policies is critical for our further actions. To date, the statistics of COVID-19 reported cases show more than 80 percent of infected had a mild case of disease, while around 14 percent of infected experienced a severe one and about 5 percent are categorized as critical disease victims. Today's report (2020-03-12; daily updates in the prepared website) shows the confirmed cases of COVID-19 in China, South Korea, Italy, and Iran are 80932, 7869, 12462 and 10075; respectively. Calculating the total Case Fatality Rate (CFR) of Italy (2020-03-04), about 7.9% of confirmed cases passed away. Compared to South Korea's rate of 0.76% (10 times lower than Italy) and China's 3.8% (50% lower than Italy), the CFR of Italy is too high. There are some effective policies that yield significant changes in the trend of cases. The lockdown policy in China and Italy (the effect observed after 11 days), Shutdown of all nonessential companies in Hubei (the effect observed after 5 days), combined policy in South Korea and reducing working hours in Iran.
