Newcastle - Thanks for asking! Being that we are from Canada, and had driven because our daughter hadn't been on a plane yet, we were over 24 hours from home and it was terrifying! I must say too though that the Centra Care Clinic that Disney uses and has the shuttle pick up guests from is the pits! We waited and waited with very sick kids, and not so sick CMs (they use for regular appointments) with a very sick baby (she was only 21 months old). Finally after waiting for hours, he did a quick swab, results came back said it was Strep, gave us our script and we went back to resort (staying at Wilderness Lodge). We totally have experience with this ourselves, so we knew what to do. The resort was amazed that we called for them to totally sterilize our room, and that we weren't going to the parks, as most parents don't do what we did - that is exactly why our DD got sick in the first place!
She had just had a full physical, and no sickness - so based on the gestation period, they knew she caught it there and she ended up in hospital a few days later with: Rotavirus, Strep, Severe dehydration, Gastroeneritis and severe acidosis! We are the most vigilant parents you will meet - she isn't allowed to touch toys, handles, wash hands constantly, etc. as her and I catch everything (I have a weak immune system/allergies, etc.), so we know about such things! Unfortunately, we must have missed something that she touched, or she was coughed on, as we went during March Break and they were having a severe (and I mean severe) Strep and Rotavirus outbreak. The emergency room doc at Orlando Regional said if we hadn't come in she would not have woken up, that was how quickly her body went down hill and we had been sitting in our room for days letting her heal up. The combination of the Strep and Rota were too much for her. They rushed us by ambulance to Arnold Palmer Children's Hospital in isolation for 2 days - tons of fluids, meds, etc. The peds were not impressed with the lack of care we received at Centra Care at all as they missed the Rotavirus, which then caused the other stuff. She literally couldn't keep a drop of water down, that's how bad it was, couple that with severe dehydration and it was very scary indeed. The worst part was that family/friends were very far away, but we had our own little suite at the hospital, so we had our own phone, washroom, etc. while she recuperated. The docs decided that she was well enough to drive home, but gave us numbers of hospitals should she need to go in again, and then my parents/best friends would have been on their way by flight to accompany us separately (one drive, one fly) back home. The drive home was the scariest journey we have ever taken. We can't say enough amazing things about Arnold Palmer's Children's hospital - amazing!
Moral of story - please don't bring sick kids to WDW, if you feel the need to (I'm not sure why), please don't bring them to the parks, pools, etc., and call housekeeping to that they can do a complete sterilization of room as well as to alert them that there is an infectious person in the room. As well, please, please, don't go traveling without health insurance. I am a teacher with platinum insurance, so every last drop of our $4200.00 USD bill was covered - I didn't have to hand over a dime at all! Last thing we learned, too many viruses in WDW in March, so we won't be going for a long while if ever again in March. Parents just aren't vigilant and many don't care about making others sick, and so we can't take another chance with our daughter by going in March.
I do hope the OP's child is feeling better. All children are different, but I constantly read on these boards how Strep isn't a big deal, or Rota isn't a big deal, and they are. The peds (and we had top notch docs) have quite a bit to say about WDW and the germ factory that it is, most especially since parents just don't understand that children's health is more important than losing a few bucks on a vacation.
Healing hugs to your child, Tiger
