Fever in Children – Causes, Symptoms & Treatment

A fever can be worrying for any parent, especially when your child feels weak, restless, or uncomfortable. But in most cases, fever is not an illness itself — it’s a natural response that helps the body fight infections. Understanding how to manage fever safely can help you stay calm and make the right decisions for your child’s health.

What Is a Fever?

A fever is a temporary rise in body temperature, often caused by an infection. For children, a body temperature above 100.4°F (38°C) is considered a fever. It’s the body’s way of activating the immune system to fight bacteria and viruses.

Common Causes of Fever in Children

Fever in children can occur for many reasons. It’s the body’s natural way of fighting infections and protecting itself. Understanding the common causes helps parents respond with confidence and proper care.

1. Viral Infections

The most common cause of fever in children is a viral infection. Viruses such as the common cold, influenza (flu), viral gastroenteritis, or respiratory infections often trigger mild to moderate fevers. These typically resolve on their own within a few days.

2. Bacterial Infections

Bacterial infections can also cause fever and may require antibiotic treatment. Examples include:

• Ear infections (Otitis media)
• Throat infections (Strep throat, tonsillitis)
• Urinary tract infections (UTIs)
• Pneumonia or sinus infections

3. Post-Vaccination Response

After immunization, some children develop a low-grade fever. This is a normal reaction as the body builds immunity against the disease. The fever usually subsides within 24–48 hours without any treatment.

4. Overheating or Dehydration

Children can sometimes develop mild fevers from overheating, such as after excessive play, exposure to high temperatures, or wearing too many clothes. Dehydration may also slightly raise body temperature.

5. Teething (Mild Temperature Rise)

While teething doesn’t directly cause high fever, some babies may experience a slight rise in temperature or irritability during teething phases.

6. Inflammatory or Immune Conditions

In rare cases, conditions like juvenile arthritis or autoimmune diseases can cause recurring or persistent fevers. These require thorough medical evaluation.

Recognizing the Symptoms

In addition to an elevated temperature, children with fever may also experience:

• Fatigue or irritability
• Chills and body aches
• Loss of appetite
• Sweating or shivering
• Dehydration (dry mouth, fewer wet diapers, dark urine)

Home Care Tips for Managing Fever

You can often care for a mild fever at home with simple steps:

1. Keep your child hydrated: Offer plenty of fluids like water, soups, or electrolyte drinks.
2. Light clothing: Dress your child in breathable clothes to prevent overheating.
3. Rest: Encourage adequate rest and sleep to help the body recover.
4. Comfortable environment: Keep the room cool and well-ventilated.
5. Medication (if needed): Paracetamol or ibuprofen can be used as per your doctor’s advice — never exceed the recommended dose.

Conclusion

Fever in children is common and often a sign that the body is fighting off an infection. With proper care, hydration, and medical guidance, most fevers resolve without complications. As a parent, staying informed and calm is the key. Remember, if you ever feel unsure, consult your pediatrician promptly — your child’s health and comfort always come first.
