I added the symptoms from wikipedia in my corona page. The most important ones are fever, fatique and headaque. In the top 10 countries with the most deaths the US and the UK are rising. China is stable for a while.
In my own country the Netherlands the real number of cases is unknown. Only when people are very sick they get a test because of the shortage of test material. At this moment my girlfriend had fever two days ago and stil suffers from fatigue. It is unknown if this is Corona or just a little bit of seasonable flu.
