Understanding Fevers
A fever is defined as a core body temperature of 38°C (100.4°F) or higher. To ensure an accurate reading, always use a thermometer rather than relying on touch.
Choosing the Right Thermometer
Forehead thermometers are often inaccurate and are not recommended for medical assessment. Please use the following methods based on your child's age:
Infants (Under 1 Year): A rectal thermometer provides the most accurate core temperature.
Children (Over 1 Year): You may use an ear, armpit, or mouth thermometer.
When to Seek Care for Fever
Guidelines for seeing a doctor depend on your child’s age and the duration of the fever.
Immediate Action
Newborns (2 months or younger): Take your baby to the Emergency Room immediately if they develop a fever of 38°C (100.4°F) or higher.
Scheduling an Appointment
Infants (2 to 3 months): Should be seen by a doctor for any fever, though an Emergency Room visit is typically not required unless they appear very unwell.
Children under 5 years: See a doctor if a fever lasts for more than 3 days.
Children 5 years and older: See a doctor if a fever lasts for more than 5 days.
Infants and children should be seen sooner if there are other symptoms that are worrisome. Your doctor is your partner in keeping your child healthy.
The Truth About Fevers
It is a common misconception that a fever is dangerous. In reality, a fever is a sign that your child’s immune system is working exactly as it should to fight off an infection.
Treat the Child, Not the Number
We do not treat the fever itself; we treat how your child feels.
The "Magic Number" Myth: There is no relationship between the height of a fever and the severity of an illness. A child can have a simple cold with a 40°C fever, or a more serious infection with a very low-grade fever.
Safety: It is biologically impossible for a fever to go high enough to cause brain damage.
Seizures: While some children experience "febrile seizures" between 6 months and 6 years of age, these are not caused by how high the temperature goes.
Comfort Measures
If your child is uncomfortable, fussy, or not feeling like themselves, you can use Tylenol (Acetaminophen) or Advil (Ibuprofen) to help them feel better.
