Dengue Fever in Children: Symptoms, Warning Signs, and When to Seek Care

Dengue fever symptoms in children are similar to those in adults, though they may present differently. Common signs include:

Typical Symptoms

• High fever (104°F / 40°C or higher): Often the first symptom, lasting 2–7 days.
• Headache: Can range from mild to severe, persisting several days.
• Eye pain: Frequently described as a deep “behind the eyes” ache.
• Muscle and joint pain: May be severe enough to limit movement or walking.
• Nausea and vomiting: Varies in intensity, lasting several days.
• Diarrhea: Usually mild but can become severe.
• Rash: Appears 2–5 days after onset, lasting 2–4 days; typically red or pink and sometimes itchy.
• Bleeding: Less common; includes nosebleeds, gum bleeding, or easy bruising.

Additional Signs in Children

• Lethargy: Can be profound, making it hard for the child to stay awake.
• Loss of appetite: Increases dehydration risk.
• Irritability: May complicate caregiving.

When to Seek Medical Attention

Consult a healthcare provider if your child shows any dengue symptoms. This is especially urgent for children under 2 years old, who face a higher risk of severe complications like dengue hemorrhagic fever or shock syndrome.

Treatment

No specific antiviral exists; care focuses on symptom relief and preventing dehydration:

• Rest: Encourage plenty of rest.
• Fluids: Offer water, oral rehydration solutions, or electrolyte drinks frequently.
• Pain relievers: Use acetaminophen (paracetamol) for fever and pain. Avoid aspirin and ibuprofen, as they can increase bleeding risk.
• Cool compresses: Apply to forehead and neck to help reduce fever.
• Lukewarm sponge bath: For very high fevers, a tepid sponge bath can help lower body temperature.

Prevention

No widely available vaccine exists for children in all regions, so mosquito bite prevention is key:

• Insect repellent: Use EPA-registered products containing DEET, picaridin, or oil of lemon eucalyptus (follow age guidelines).
• Protective clothing: Long sleeves, pants, and socks when outdoors in mosquito-prone areas.
• Mosquito netting: Use over beds and strollers.
• Eliminate standing water: Empty containers, tires, gutters, and flower pots where mosquitoes breed.

Following these steps can significantly reduce your child’s risk of dengue infection.
