Fever in Kids

Causes, Recognizing Symptoms, and Knowing When to Get Help

Fever is a common occurrence in children and is often a natural response to an infection or illness. As a parent or caregiver, it can be alarming to see your child with a high temperature, but it’s essential to understand that fever is not always a cause for panic. In this blog, we will explore what fever is, its causes, common symptoms, and when to seek medical attention for your child’s fever.

What is Fever?

Fever is defined as a temporary increase in body temperature above the normal range. In children, a rectal temperature of 100.4°F (38°C) or higher is typically considered a fever. However, the exact definition may vary slightly based on the method of measurement (e.g., oral, axillary, ear).

Causes of Fever in Children

1. Infections: The most common cause of fever in children is infections, such as viral or bacterial infections. Common illnesses that can cause fever include colds, flu, ear infections, strep throat, and urinary tract infections.

2. Immunizations: Some children may experience a mild fever as a side effect of certain vaccinations. This is usually a normal response and should subside within a day or two.

3. Teething: When infants and toddlers are teething, they might experience a slight increase in body temperature, but it’s typically not high-grade fever.

4. Inflammatory conditions: In some cases, fever may be triggered by inflammatory conditions like juvenile arthritis or Kawasaki disease.

5. Heat-related causes: Prolonged exposure to hot weather or overdressing can lead to fever in children.

Symptoms Associated with Fever

Apart from an elevated body temperature, children with fever might experience the following symptoms:

1. Irritability or fussiness

2. Fatigue or lethargy

3. Loss of appetite

4. Chills and shivering

5. Sweating

6. Headache or body aches

7. Rapid breathing

8. Flushed face or skin rash

9. Dehydration (dry mouth, decreased urine output)

When to Seek Medical Attention

While fever is often a sign that the body is fighting off an infection, there are situations where medical attention should be sought promptly:

1. Infants under 3 months: If an infant under 3 months of age has a fever, it’s crucial to contact a healthcare provider immediately, as it can be a sign of a serious infection.

2. High fever: If your child’s temperature is 104°F (40°C) or higher, medical attention should be sought promptly.

3. Persistent fever: If the fever lasts for more than a couple of days or is accompanied by other worrisome symptoms, consult a doctor.

4. Severe symptoms: Difficulty breathing, seizures, severe headache, neck stiffness, or a rash that doesn’t fade when pressed are all red flags that require medical evaluation.

5. Underlying health conditions: If your child has pre-existing medical conditions or a weakened immune system, it’s best to seek medical advice for any fever.


Fever in children is a common and generally harmless occurrence that is often a sign of their body fighting off infections. As a parent or caregiver, it’s essential to stay informed about the potential causes of fever and monitor your child’s symptoms closely. While most fevers will resolve on their own, don’t hesitate to seek medical attention if you have concerns about your child’s well-being or if the fever is accompanied by severe symptoms. Remember to keep your child hydrated and provide comfort during this time. Always consult a healthcare professional for personalized advice and guidance.
