Hi,If you allow me, I'd like to write here what I wrote in the March 21 session's thread with a a few changes. I think it could add something maybe interesting according to this subject.In october 2018 (and not January /Feb 2019 like I thought) when I lived in Seoul (South Korea) with my wife, she got sick with a kind of flu, and of course, she shared it with meGenerally speaking, I'm pretty lucky because I'm in a good health and so, not often ill, maybe once a year with a cold. But this time, it was like my head was going to explode, some fever, big throatache, dry coughing with some pain in the chest and finally my tasting feeling changed and got modified for a few days. I don't use to take medecine but this time I finally got to the emergency unit in an international hospital especially because of the headache, it avoided me to sleep at night, I was completely exhausted. They told me it was a kind of flu. I remember that they tested me about something like H1N1 or else but it was negative. They gave me some pills for the fever and headache (it did nothing) and told me that it would heal by itself like a flu.These symptoms went out after a week. It really was a kind of sickness I had never felt before especially the headache and the modification of my taste feeling for a few days. This last point made me fear that I could lose part of my taste forever !It was a bit strange for me because it was unfamiliar. For me, the symptoms were not common for a season flu and I didn't use to get so sick.Nowadays, after having read the Cs remark about the appearance of the covid 2 years ago, I think that it might have been the corona virus, even in an early stage before any kind of mutation.And to conclude about that, I just inform those who don't know it, that at this period, there were still many american people in Seoul because of the american base in the center of the town. Today, this base has been moved to Pyeongtaek, out of Seoul towards the south.FWIW
