When Should You Worry About a Fever?

A fever can feel worrying, especially when your child is uncomfortable or behaving differently than usual. In most cases, however, fever is not an illness itself. It is a natural response that often appears while the body is fighting an infection.

A temperature of 38°C or 100.4°F and above is generally considered a fever. The number on the thermometer matters, but your child’s overall condition is often just as important. A child who is drinking, responding normally and becoming more comfortable may be less concerning than a child with a lower temperature who appears unusually unwell.

Look at your child, not only the thermometer

Pay attention to how your child is breathing, drinking, interacting and responding to you. Signs such as unusual sleepiness, difficulty waking, persistent distress, breathing difficulty, repeated vomiting, dehydration or a concerning rash require medical attention.

It can be reassuring when a child begins playing, talking or drinking again after resting or receiving appropriate medicine for discomfort. However, contact your pediatrician if your child continues to appear very unwell or seems to be getting worse, even if the temperature comes down.

When should you contact a doctor?

Contact your pediatrician promptly when:

• Your baby is younger than three months and has a temperature of 38°C / 100.4°F or higher.
• Your child is difficult to wake, unusually drowsy or not responding normally.
• Your child is struggling to breathe or breathing much faster than usual.
• There are signs of dehydration, such as a dry mouth, very few wet diapers, sunken eyes or no tears when crying.
• Your child has a stiff neck, seizure, repeated vomiting or a rash that does not fade when pressed.
• The fever repeatedly rises above 40°C / 104°F.
• Your child has an immune-system condition or another medical condition that may increase the risk of complications.

The American Academy of Pediatrics also recommends contacting a doctor when fever lasts longer than 24 hours in a child under two years old, or longer than three days in a child aged two years or older.

Caring for a child with fever at home

Encourage regular fluids and allow your child to rest. Dress them comfortably and avoid wrapping them in too many layers. Food is less important than hydration during a short illness, so do not force your child to eat if they are not hungry.

Medicine may help when a child is uncomfortable, but it should be given according to age, weight and the product instructions. Do not give aspirin to children, and speak with a pediatrician or pharmacist when you are uncertain which medicine or dose is appropriate.

Trust your instincts

Parents often notice subtle changes before anyone else. You do not need to wait for every warning sign to appear before asking for help. When your child seems significantly different from normal, cannot drink, is becoming less responsive or you simply feel that something is wrong, contact a healthcare professional.
