Yes I was about to say the same thing as Crayola Kiddies...Scarlet Fever is actually a symptom of something else. Generally speaking it is strep or staf. My son gets scarlet fever every single time he has strep and he is 10 now. The rash isn't contagious...I would get back in touch with the parents asap and ask them what else the doctor said as there must be a cause for the rash and I'd want to make sure that he was being treated before the child were allowed to return to daycare.
