Fever is a symptom, not a disease. It represents the body’s normal response to infections and plays a role in fighting them. Fever turns on the body’s immune system.
The usual fevers (100°-104° F) that all children get are not harmful. Most are caused by viral illnesses and may last 3 to 5 days. Viral illnesses do not respond to antibiotics. Most office visits for fever will result in no specific treatment except watchful waiting. Your doctor will tell you what to expect and when they may want to recheck your child.
To learn more on how to take your child's temperature, and for information on dosing Tylenol, Motrin, or Benadryl when it is advised, download this handy Dosing and Fever Guide pdf.
