Question:
My child was recently treated for the flu. Here is the timeline of their treatment and symptoms:
Day 1: Received IV fluids and antipyretic/anti-inflammatory IV therapy.
Day 2: Received another antipyretic/anti-inflammatory IV.
Day 3: Had a fever of 38.2°C and took a fever reducer.
Day 4: Took the last fever reducer at 8:00 AM for a fever of 38.0°C.
Day 5: Body temperature returned to normal.
Day 6: Visited the clinic at 10:00 AM. The doctor said my child was fully recovered, stopped the antibiotics, and only prescribed rhinitis medication. However, at 7:00 PM, the temperature was 37.5°C, and by 9:00 PM, it reached 38.0°C (no fever reducer was given).
Day 7: At 12:30 AM, the temperature was 37.5°C. Throughout the night, it remained normal or peaked at a maximum of 37.5°C.
Given this slight rebound in temperature, should we go back to the hospital?
Answer:
It is completely understandable that you are worried about the return of a mild fever, especially after hearing that your child had fully recovered just that morning.
Current Assessment:
During the recovery phase after the flu, a child's body temperature regulation can sometimes be unstable. A temperature of 37.5°C to 38.0°C is considered a mild fever. If your child appears comfortable, you can safely continue to observe them without administering a fever reducer. The most important factor right now is your child's overall condition and behavior.
When to Revisit the Doctor:
Please take your child back to the clinic for a re-evaluation if you notice any of the following symptoms:
A persistent fever of 38.5°C or higher
Worsening cough or an increase in phlegm
Difficulty breathing
Poor appetite or noticeable lethargy
Complaints of ear pain
Home Care Management:
Ensure your child stays well-hydrated by offering plenty of fluids, such as warm water or mild tea.
Maintain a comfortable indoor humidity level between 40% and 60%.
Encourage plenty of comfortable rest.
Please keep in mind that secondary bacterial infections or otitis media (middle ear infections) can sometimes develop after a bout of the flu. If the fever persists into the morning or if any new symptoms arise, please visit your pediatrician for an in-person evaluation. Continue to monitor your child closely, and do not hesitate to visit the emergency room if you become highly concerned about their condition overnight.
