Description
A short-term rise in body temperature that's often caused by an infection.
Self-care
Get plenty of rest. Keep the room temperature cool. Drink water and clear broth. Give a baby under 6 months with a fever only breast milk or formula. Adults who have discomfort from a fever can take acetaminophen (Tylenol, others) or ibuprofen (Advil, Motrin IB, others). These medicines are available in children's and infants' versions. Ask a child's pediatrician how much medicine to give. Don't give aspirin to children, as it may cause a rare, serious condition.
