I wish I could, since you obvioulsy remember my description of my suffering with Sinusitis. But it was diagnosed as a virus- "live with it". It lasted about 6 weeks, but wasn't very contagious. I didn't cross-pollinate anyone, to my knowledge.
I cannot wait for the time that they can perform real-time health checks at airports -- a little prick of the finger
Certain airports have pyrometers aimed at the passengers to see if anyone has a fever. I have seen them at Hong Kong and Johannesburg and I think at a pedestrian entry to mainland China through Hong Kong. I have never seen anyone stopped though.
and they thery say "you can get on -- but you have to come back next week" ...
Two problems- you are ascribing a degree of accuracy to medical diagnosis which I don't think exists and I am sure the airline will want compensation for changing the ticket- do you know how much that costs?!!
