  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.
