Question:
My child started having a fever five days ago. On the second day, we visited the doctor, who suspected a simple cold. We administered fever reducers, and the temperature stayed around 38°C. Two days later, the temperature fluctuated between a mild fever and normal without any medicine, so I thought my child was recovering.
However, the next morning at 4 AM, the fever spiked to 39°C. We gave medicine and visited the clinic again later that morning when the temperature was normal; the doctor sent us home, saying it still looked like a simple cold. Unfortunately, the fever spiked to 38.5°C that afternoon and again to 38.8°C early this morning.
While the fever reducers work quickly, the high fever returns every 10 hours. Additionally, my child's runny nose, phlegm, and cough are worsening, and their energy levels are noticeably dropping. Since it is Sunday, our regular clinic is closed. Should we wait one more day, or should we go to an open weekend clinic to get a flu test?
Answer:
It is completely understandable that you are worried about the recurring high fever over the past 5 days and the worsening symptoms. The drop in your child's energy levels is especially concerning.
Based on the situation you described, here is a clinical assessment:
A fever pattern that has persisted for 5 days.
Fever reducers are effective, but the high fever rebounds every 10 hours.
Respiratory symptoms (runny nose, phlegm, cough) are progressively worsening.
Decreased vitality and energy levels (this is the most concerning factor).
⚠️ I strongly recommend that you seek medical attention today. A fever lasting for 5 days or more, combined with decreased energy and worsening respiratory symptoms, suggests something beyond a simple cold. Re-evaluation is necessary to rule out the flu or other secondary infections.
Please go to the Emergency Room immediately if your child shows any of the following signs:
Difficulty breathing or chest retractions (the chest pulling in with each breath).
Altered mental status, lethargy, or inability to respond normally.
Refusal to drink any fluids.
No urine output for more than 8 hours.
Finding Medical Care Today:
Since your regular clinic is closed, please search for a local pediatric clinic that is open on weekends or visit a hospital with a pediatric emergency room.
What to prepare for your hospital visit:
Fever Log: A record of the highest temperatures recorded each day.
Medication Log: A list of the exact times and dosages of the fever reducers given.
Test Requests: Be prepared to discuss your child's symptoms and ask the doctor if a flu or COVID-19 test is appropriate.
Please make sure your child is evaluated by a doctor today. In the meantime, continue to offer frequent, small sips of fluids to keep them well-hydrated.
