My granddaughter is 11 months old had a 103 fever, diarrhea and was threw up just once.  My daughter took her to the hospital last night and they found nothing wrong.  Is this some kind of virus.  She has never been sick until she started going to day care.
Hi... Thank you for consulting in Chat Doctor .KIDS CAN GET VIRAL ILLNESS FORM DAY CARE FROM OTHER KIDS - IT IS COMMON. Fever of few days without any localizing signs could as well a viral illness. Usually rather than fever, what is more important is the activity of the child, in between 2 fever episodes on the same day. If the kid is active and playing around when there is no fever, it is probably viral illness and it doesn't require antibiotics at all. Once viral fever comes it will there for 4-7 days. So do not worry about duration if the kid is active. Paracetamol can be given in the dose of 15 mg/kg/dose (maximum ceiling dose of 500 mg) every 4-6th hourly that too only if fever is more than 100F. I suggest not using combination medicines for fever, especially with Paracetamol. Hope my answer was helpful for you.  I am happy to help any time.
