Question:
My 32-month-old toddler developed a high fever last night, reaching 38-39°C (100.4-102.2°F) without any other symptoms like a cough or runny nose. We went to the hospital this morning. Tests for COVID, the flu, and a blood panel all came back negative. My child received IV medication, which brought the fever down, but it returned this evening. Even after alternating fever reducers as prescribed, the temperature is still over 39°C. The child fell asleep easily and is currently sleeping. Should I take my toddler to the emergency room if the fever stays this high?
Answer:
It must be very concerning that your 32-month-old's high fever isn't resolving. It's likely even more worrying since the fever has persisted despite a hospital visit and tests today.
Current Situation Assessment:
* A persistent high fever of 39°C with minimal response to fever reducers.
* However, the child is sleeping well, which is a good sign.
* Tests performed this morning did not identify a specific cause.
Please Check These Signs Now:
1. While sleeping, is your child's breathing normal?
2. If you wake your child, are they responsive? Can they drink water?
3. How many times has your child urinated today?
→ Go to the emergency room if you observe: Fast or labored breathing, unresponsiveness even when awakened, or no urination for more than 8 hours.
→ Continue to monitor at home until morning if: Your child is sleeping well, is responsive when awakened, and is urinating.
What you can do at home:
* Dress your child in light clothing and maintain a room temperature of 24-26°C (75-79°F).
* Check their temperature every 1-2 hours.
* When your child is awake, offer small, frequent sips of water.
Since you are already alternating fever reducers, it is crucial to follow the prescribed schedule precisely. If the fever remains above 39°C tomorrow, you should see your doctor again for a follow-up. Further evaluation may be necessary if an unexplained high fever lasts for more than three days.
