My son and nephew had it 2 weeks ago in Disney. I'm a nurse and went on a research trip years ago when the Niro first came out, to discover why it was running rampant through cruise ships, so this is not foreign to me. However, I really wish it hadn't hit in Disney! When my son got it, I disinfected as though I was in an OR, it was a fully sterile field In the Beach club by the time I was done! My nephew contracted it 2 days later, so I'm thinking this strain has a slower incubation period than the one years ago (it was hours after exposure that people started with symptoms in 2001). All that being said, I think either A. Someone who stayed in the suite before us had it, my son and nephew shared a bed the night before my son was sick, and that's where the sick person had slept or B. my son picked it up somewhere in the park, because he's 4 and has to touch EVERYTHING, and he shared with his cousin. I was much more ridiculous about germ x and hand washing after that sleepless night, and no one else caught it!
My advice for travelers, Lysol wipe your plane seats, trays, seat belts, etc. scrub, and I mean scrub, before you eat. Don't rely on hand sanitizers, actually wash your hands with soap and water for at least as long as two "happy birthday" songs would take. And Lysol your hotel room, even going so far as to run pillows through the dryer if you have the option. I'm not messing around next trip, my family can call me crazy all they want, but I'm not losing another nights sleep and day in the park with a bug!
