My child has a fever: when should I worry?

By Dre Aurélia Nha-Huyen Nguyen Gouez, family physician and medical director of French origin, based in Quebec since 2016.

Seeing your child with a fever can be very worrying, especially when they are small, crying a lot, or appearing lethargic. Should you seek a consultation immediately? Wait for it to pass? Give medication? Here are some simple guidelines to better understand fever and know when it is time to consult a doctor.

What is a fever in children?

We speak of a fever when the rectal temperature exceeds 38 °C. In children, fever is a symptom, not a disease. It generally reflects the body's natural response to an infection (most often viral, sometimes bacterial).

Fever is common and often benign, especially in children from 6 months to 5 years old. However, certain signs should be alerting.

When can we simply monitor at home?

You can generally manage a fever at home if:

• The child is over 6 months old

• They are still active, eating and drinking a bit

• The temperature drops after Tylenol (acetaminophen) or Advil (ibuprofen)

• They have no significant respiratory difficulty

• They remain responsive and recognize you

In these cases, it is very often a benign virus that will disappear in a few days.

When should you consult a doctor?

Here are the situations where a medical consultation is necessary:

• Fever that persists for more than 72 hours without improvement

• Temperature above 40 °C that does not decrease despite medication

• The child refuses to drink, is very drowsy, or difficult to wake up

• Marked respiratory signs (retractions, shortness of breath, rapid breathing)

• Significant diarrhea or vomiting risking dehydration

• Localized pain (throat, ears, stomach, joints, etc.)

• Febrile seizures or a history of seizures

When should you go to the emergency room?

It is a medical emergency if:

• Your baby is under 3 months old with a rectal temperature ≥ 38 °C,

→ This may indicate a maternal-fetal infection or a serious infection requiring immediate hospital evaluation.

• Your child has a febrile seizure lasting more than 3 minutes

• They become pale, bluish, very drowsy, or have abnormal breathing

• You are unable to get them to drink or they cannot keep any liquids down
