Question:
Hello, my 6-year-old child developed a fever of 39°C a few nights ago. We got tested the next day, and it was confirmed to be Influenza A. My child received a fever-reducing injection, and yesterday the fever went down to 37.5°C. However, today the fever has spiked back up to 38.9°C. Should we go back to the hospital?
Answer:
Hello. It is completely understandable to be concerned when a fever returns after an Influenza A diagnosis. Unlike a common cold, it is very common for a fever caused by the flu to fluctuate and go up and down for 3 to 5 days. The temperature can easily spike again once the effects of the fever-reducing medication wear off.
Here are a few important things to monitor and manage at home:
• Antiviral Medication: Ensure your child is taking any prescribed antiviral medication (such as Tamiflu) as directed, as starting it within 48 hours of diagnosis is highly effective.
• Fever Management: You can alternate fever reducers if necessary. For a 6-year-old, it is generally safe to give Acetaminophen every 4 hours and Ibuprofen every 6 hours to help control the fever.
• Hydration & Rest: Offer water or electrolyte drinks in small, frequent sips to ensure your child is urinating normally, and encourage plenty of rest.
You should take your child to the hospital immediately if you notice any of the following warning signs:
• Their breathing becomes fast, labored, or difficult.
• They appear lethargic, confused, or have trouble making eye contact and responding to you.
• The high fever persists for more than 5 days.
• They are unable to keep their medication or fluids down due to severe vomiting.
The flu typically runs its course over 5 to 7 days. If your child is currently taking antiviral medication and has no severe warning signs, it is generally safe to monitor them at home for another day. However, if your child's overall condition appears to be worsening or you remain concerned, please do not hesitate to visit your pediatrician for an in-person evaluation.
