Hi,
I got very ill in late December almost at the same time I heard about corona epidemic in china, since I am in Thailand and they have direct flight from Wuhan to Bangkok, it raised an alert for me, but I didn't overthink the situation and didn't test it for corona that time either, then I guess I will never know what it was.
It was about 3 days of pure hell, couldn't breath well, fever was high at 39, no cough, no sneeze at all, but a huge headache and eye pain(I did think it was Dengue, since there is an outbreak going on right now). It was very bad, can't remember feeling like that in a long time, but it went away all by itself. Also I kept eating greens and fruits all day long and water(hot water is good), during the night a hot soup which made me sweating like I was in a sauna!
Whatever it was I am okay now.
