Fever Q&A

What is a fever?

Fevers occur when your child’s body temperature rises above normal levels. They can occur as a result of ear, bladder, skin, or throat infections, from vaccinations, or even from inflammation related to teething.

Your hypothalamus is the part of your brain that controls your body temperature. An infection, illness, or other condition can trigger your hypothalamus to raise or lower your temperature. Within a specific range, fluctuations are a sign of a healthy immune system.

Based on how you take your child’s temperature, these are the measurements that indicate a fever:

  • 100° if measured orally
  • 100.4° if measured rectally
  • 99° if measured under the arm

How can I help my child find relief from a fever?

Childhood fevers are common, but they’re no fun for parents or children. If your child has a fever, be sure to limit activity and keep a close watch for symptoms. These homecare efforts can help your child feel comfortable:

  • Children’s acetaminophen or ibuprofen (Never give your child aspirin, as it increases the risk of Reye’s Syndrome)
  • Dress your child in lightweight clothing
  • Keep the room at a comfortable temperature
  • Encourage your child to drink fluids


If a child under three months has a fever, you should call or visit your pediatrician.

When should I call the pediatrician about a fever?

Low-grade fevers aren't usually a cause for concern. But if you see any of these symptoms, call your pediatrician:

  • Temperature of 102.2° or higher (100.4° for infants younger than three months)
  • Inability to take in fluids
  • Persistent diarrhea or vomiting
  • Lethargy
  • Rash
  • Fever that lasts more than 24 hours
  • A specific complaint in addition to fever (an ear ache or sore throat, for example)
  • Inability to stop crying
  • Severe headache  
  • Difficulty breathing


You know your child better than anyone. If you’re worried your child is unwell, call Dr. Oparaugo to share your concerns and receive advice on what type of care is needed. You should never feel foolish or hesitant to call your pediatrician’s office.


Caring for children is a pediatrician’s sole focus. Dr. Oparaugo and his staff would much rather hear what your child’s symptoms are, and probably be able to reassure you that there’s nothing to be concerned about, than have you hesitate to contact Good Choice Pediatrics.
