Review health risks that may increase the seriousness of your child's symptoms.

Note:
  • Be sure to try home treatment when your child has a fever. Sometimes home treatment is all that is needed to help lower your child's fever and help your child feel better.
  • If you are not able to measure your child's temperature, look for other symptoms of illness. Remember, fever is only a symptom, and often the importance of a fever can only be determined when other symptoms are evaluated.
  • It is not unusual for a young child to have 7 to 10 viral infections in a year. Each new viral infection may cause a fever. It may seem that a fever is ongoing, but if 48 hours have passed between fevers, then the new fever is most likely from a new illness.
