Germany, Coronavirus, and Timelines

I sat and watched an update video from Dr John Campbell, and he gets into viruses, and things progress.

So he points out (you can view the video as well):

19 January, the Chinese woman arrives in Germany (well, no problems).

20/21 January, the German co-worker meets up with her for presentations. 

22 January, the Chinese woman leaves Germany....flying back to China, and now starts to show symptoms on the flight. 

24 January, the German now shows symptoms (sore throat, fever, all the normal flu things).

25 January, the German (regarded as patient #1) is seriously sick with a major flu.

26 January, this German guy now starts to feel 'better'.

27 January, the German guy now goes back to work.

Patient two?  There's no doubt that he got the virus from the meeting with the Chinese woman.  But the patients since that point (3, 4, 5, etc).....they all come from patient 1 or 2.

Patient #2 odd point?  Much older guy (61) and he's got more problems than patient #1.  He's going to spend more time in the recovery phase than patient 1. 

Again, it goes to much discussed factors....if you have lung issues, COPD, etc.....you stand a chance of a more severe flu, and need significant medical attention.
