Treatment
There is no specific treatment. Patients should drink plenty of fluids, take acetaminophen, a non-steroidal anti-inflammatory (ibuprofen) or aspirin for their fever. Children should not take aspirin because of the risk of Reyes syndrome. Immediate treatment should be sought for persistent vomiting, severe headache, confusion or other serious symptoms.
