Running a fever is not necessarily bad. Your body temperature increases when sick because it is trying to fight off the bugs. High temperatures help kill bugs. If her fever goes up and does not come down then you should take her to ER.
Try a cool bath to see if fever will drop. Normally for children once temp is over 103 you should be concerned or if fever accompanied by vomiting. A fever that high indicates the body is fighting to reduce infection. Keep monitoring it and if still the same then call your doctor or take her to after hour clinic.
