Dengue Fever in Infants: A Parent’s Guide to Symptoms, Treatment, and Prevention

Dengue fever, a mosquito-borne viral infection, poses a significant health risk worldwide, especially in tropical and subtropical regions.

Understanding Dengue Fever in Infants

Dengue fever is caused by the dengue virus, which is transmitted through the bite of infected Aedes mosquitoes. These mosquitoes typically breed in stagnant water and are most active during the daytime. The virus has four distinct serotypes (DENV-1, DENV-2, DENV-3, and DENV-4), and infection with one serotype doesn’t provide immunity against others, making repeated infections possible.   

Infants and young children are at a higher risk of developing severe dengue illness compared to adults. This is because their immune systems are still developing, making them more vulnerable to the virus’s effects.   

Recognizing the Symptoms

Dengue fever in infants can be challenging to diagnose, as the symptoms can be subtle and mimic other common childhood illnesses. However, some common signs and symptoms to watch for include:   

• High fever: This is often the first and most noticeable symptom. The fever can be as high as 104°F (40°C) and may last for 2-7 days.   
• Irritability and fussiness: Infants with dengue may be more irritable and fussy than usual due to the discomfort caused by fever, headache, and body aches.   
• Poor feeding and sleep disturbances: Loss of appetite and changes in sleep patterns are also common.   
• Rash: A red rash may appear on the skin, often starting on the face and spreading to the chest, back, and limbs.   
• Vomiting and diarrhea: These symptoms can lead to dehydration, which is a serious concern in infants.   
• Bleeding: In severe cases, infants may experience bleeding from the nose or gums.   
• Warning signs of severe dengue: These require immediate medical attention:
  • Severe abdominal pain   
  • Persistent vomiting   
  • Bleeding   
  • Difficulty breathing   
  • Cold or clammy skin
  • Lethargy or drowsiness   

Causes and Risk Factors

The primary cause of dengue fever is the bite of an infected Aedes mosquito. These mosquitoes breed in stagnant water, commonly found in:   

• Flower pots   
• Buckets
• Old tires   
• Unused containers   
• Coolers   

Risk factors for dengue in infants include:

• Living in or traveling to areas where dengue is prevalent
• Exposure to mosquito bites   
• Having a weakened immune system   

Preventing Dengue Fever in Infants

Protecting your infant from mosquito bites is the most effective way to prevent dengue fever. Here are some preventive measures:   

• Use mosquito nets: Use mosquito nets over your baby’s crib or bed, especially during the day when Aedes mosquitoes are most active.   
• Dress your baby in protective clothing: Cover your baby’s arms and legs with long-sleeved clothing and pants.   
• Use mosquito repellent: Apply mosquito repellent to exposed skin, but choose a repellent that is safe for infants and follow the instructions carefully.   
• Eliminate mosquito breeding sites: Remove any standing water around your home where mosquitoes can breed.   
• Keep your home clean and well-ventilated: This can help reduce the number of mosquitoes in your home.   

Diagnosis of Dengue Fever in Infants

Diagnosing dengue fever in infants can be challenging, as the symptoms can mimic other illnesses. Your doctor will likely ask about your baby’s symptoms, travel history, and potential exposure to mosquitoes. They may also perform a physical examination and order blood tests to confirm the diagnosis.   

Treatment for Dengue Fever in Infants

There’s no specific antiviral treatment for dengue fever. Treatment focuses on managing symptoms and preventing complications, especially dehydration. This may include:   

• Hydration: Give your baby plenty of fluids, such as breast milk, formula, or oral rehydration solutions (ORS), to prevent dehydration.   
• Fever control: Use acetaminophen or paracetamol to reduce fever and discomfort. Avoid giving aspirin to infants.   
• Rest: Ensure your baby gets plenty of rest.
• Medical care: If your baby shows any warning signs of severe dengue or if you’re concerned about their condition, seek immediate medical attention.
