When should I take my child to the doctor or the hospital?
If your child has any of the following signs, he or she should see a doctor:1

- Your child just started a new medication and also has a rash
- Your child has recently received chemotherapy

- The fever has lasted longer than 24 hours without any obvious signs of an infection (e.g., cold, earache, stomach bug, etc.)
- The fever has lasted for 3 days with or without treatment with medications, (e.g., acetaminophen (Tylenol®) or ibuprofen (Advil®))
What are the signs and symptoms of fever?

Other signs and symptoms of fever may include:

MYTH: My child has a fever if he or she feels warm.
How warm skin is to touch is NOT the most accurate way to tell if your child has a fever. This is because how warm your child’s skin feels depends on the temperature of your hand.1 The best way to confirm fever is to measure your child’s temperature using a thermometer.
