I was in China the last two weeks of October 19. we visited factories also near wuhan. One day after return my boss was seriously sick. About 4 days later I experienced a „cold“ like never in my life before. <br>A friend of mine was in Korea in November 19 and experienced a similar extreme cold like I did. <br>November 20 I was officially infected and tested positive. It was very similar but the long lasting effects were much more severe. <br>I expect I had it twice with two different mutations. My theory is that it was ok in China until beginning of 2020 where the mutation happened and it got serious.this mutation is the one that lead to China shutting down everything.<br>So this fits the theory that the virus was around way longer than officially stated.
