These numbers are as of February 15, 2020 and are taken from WHO’s situation reports, the National Health Commission (NHC) of the People’s Republic of China, and the Health Commission of Hubei Province, China. Links are provided at the bottom.

Note: I’ve received a lot of comments about the inaccuracy of these numbers and the interpretation of them. The information below is information retrieved from other sources and is not influenced by my subjectivity. Also, keep in mind that the numbers continue to differ from the ones below as time goes by. Nonetheless, take what you would like from this and enjoy!

1) 98.87% of the coronavirus cases are based in China

More specifically, 68,509 out of the 69,289 total cases are based in China. Equivalently, this means that there’s approximately one case outside of China for every 87.5 cases in China.

2) Furthermore, approximately 81.7% of the cases in China are from Hubei.

This makes up about 71.5 of the 87.5 cases as shown above. Guangdong has the second highest number of cases (1294), followed by Henan (1212), Zhejiang (1162), and Hunan (1001).

3) 9,883 people who tested positive have recovered

That represents 86% of the 11,554 closed cases and 14% of the total number of cases.

4) Of the 29 countries affected, there are eight countries where all cases have recovered from the infection

The list of countries include India (3), Russia (2), Spain (2), Belgium (1), Sri Lanka (1), Finland (1), Cambodia (1), and Nepal (1).

Green represents countries that have recovered from all cases. Red represents countries with active cases.

5) The estimated mortality rate is 2%

The mortality rate is defined as the number of deaths in a given area or period, or from a particular cause.

On February 4, 2020, the National Health Commission (NHC) of China announced that the current mortality rate (also known as case fatality rate or CFR) was 2.1%. This was calculated by taking the cumulative current total deaths divided by the current number of confirmed cases. [1]

In comparison, the CFR was 10% for SARS and 34% for MERS.

6) The growth factor has been trending downward and has been below 1.00 for the past three days.

The growth factor is calculated as the number of new cases today divided by the number of new cases yesterday. For example, if there were 107 cases today and 100 cases yesterday, the growth factor from yesterday to today would be 1.07.

A growth factor below 1 or a growth factor above 1 but trending downwards is a good sign that the spreading of the virus is plateauing. On the other hand, a growth factor above 1 signals exponential growth.

The cause of the spike on February 12 is explained in the next point and the drop to 0.37 on the following day is partly due to a correction of the number of reported cases due to “repeated statistics”.

8) There were 14,840 new cases in Hubei on February 12, 2020.

This was mainly due to the adoption of a new diagnosis classification, which ultimately contributed 13,332 of the 14,840 new cases that day. As of Feb 12, Hubei and all other provinces will include the number of clinically diagnosed cases in addition to the number of confirmed cases.

9) Approximately 80% of those who died were over the age of 60 and 75% had pre-existing health conditions such as cardiovascular diseases and diabetes. [2]

Therefore, if you are young and healthy, statistically speaking, it’s unlikely for the coronavirus to be fatal should you catch up.
