To say nothing about all the surfaces that contain germs in the airport, and the magical Express bus or taxi, and in each Park, bus, and everywhere else.
I came home from my last trip with influenza. It came from Disney world. There have been no other verified cases in my city so far this year, I have the notoriety of being patient one. Where did that come from?
When I am traveling,I use hand sanitizer continually, I wipe down surfaces in my resort room, and I try to practice good hygiene everywhere. But, those germs and viruses and bacteria are all around us.
