Someone just pointed me at this thread... my wife, son, and I have been at WDW since Sunday (the 18th) and a few days ago, my son started vomiting a lot but no sign of the "D" word. He seemed OK the next day, but yesterday, he vomited shortly after waking up and ended up with pretty bad diarrhea by the afternoon and through the rest of the day. My wife also had a bad vomiting episode after we got off the bus at AK. She actually felt a little better afterwards, but went downhill again later and she and my son ended up spending the afternoon and evening in the room, with my wife suffering at both ends.
This morning, she seems better (though still no appetite) and my son seems better. I've managed to avoid it all. Whatever it is, though, it's definitely still around!
BTW, don't bother with Airborne. It's a homeopathic product, which means that it's basically just a sugar pill with the active ingredients diluted to a virtually non-existant level. Airborne itself has recently had to settle a $30mill lawsuit and another $7mill one just last month for false advertising claims, and there's no evidence that it does anything whatsoever that it says that it does. These products have zero testing by the FDA (except to make sure you won't drop dead if you take it) and have no legal need to back up any of their outlandish claims. It's just anecdotal evidence and psychosomatic effects. The only reason such things even share shelf space with real medicine is due to heavy lobbying in the '90s and a law passed in 1994 that treads "alternative medicine" as food instead of medicine. IMHO these snake oil peddlers ought to be tarred and feathered.

Back on topic - yes, there is still definitely something going around! Make sure to do lots of hand-washing!
