Question:
My school-aged child has a mild underlying mitochondrial disease. They were diagnosed with Influenza A yesterday morning and received an IV antiviral treatment. They had chills and a high fever up to 40°C all day yesterday, with the temperature only briefly dropping to 38°C. After taking ibuprofen syrup early this morning, their current temperature is 39°C. However, their overall condition seems fine. They have no chills, say they don't feel sick, and are refusing to take more fever-reducing medicine. Should I force them to take the medicine just to lower their temperature?
Answer:
It is completely understandable to be extra concerned about the flu since your child has an underlying mitochondrial disease. Even after receiving antiviral treatment yesterday, seeing a persistent 39°C fever can be worrisome.
Current Situation Assessment:
• Diagnosed with Influenza A and currently under antiviral treatment.
• Persistent 39°C fever, BUT the child's overall condition is good.
• No chills; the child feels comfortable.
• The underlying disease requires careful monitoring.
Fever Reducer Guidelines:
If your child is currently comfortable, there is no need to force them to take a fever reducer just because their temperature is 39°C.
→ A child's overall condition and behavior are much more important than the number on the thermometer.
→ High fevers from the flu can typically last for 2 to 3 days.
When a Fever Reducer is Necessary:
• The child begins to struggle, look unwell, or become irritable.
• They refuse to drink fluids or have no appetite.
• They complain of headaches or muscle aches.
• They are unable to sleep or seem physically uncomfortable.
Special Considerations for Mitochondrial Disease:
→ Preventing Dehydration: This is especially critical. Encourage sips of water or electrolyte/sports drinks every 30 minutes.
→ Energy Supplementation: Drinks containing sugar are acceptable and helpful for maintaining energy levels.
→ Sufficient Rest: Ensure they get plenty of uninterrupted rest.
⚠️ When to Visit the Hospital Immediately:
• Difficulty breathing or chest pain.
• Decreased consciousness, severe lethargy, or confusion.
• High fever persisting for more than 3 days.
• Inability to stay hydrated due to severe vomiting.
For now, continue to monitor your child's condition and let them rest comfortably without forcing the medication. Because your child has an underlying mitochondrial disease, it is highly recommended to communicate closely with their primary pediatrician or specialist regarding their progress and consult them immediately if you notice any concerning changes.
