Question:
My child was diagnosed with the flu on Thursday, received IV fluids with fever reducers, and started taking Tamiflu. By the next morning, the fever dropped to 37.0°C, and their temperature has generally been normal since. However, they still have a wet cough and a hoarse voice. Right before bed, their temperature was 37.3°C, and now, two hours after falling asleep, it is fluctuating between 36.9°C and 37.1°C. Isn't this a bit high for sleeping? They are also coughing in their sleep. Is this because the virus is still in their body? Lastly, what is a normal body temperature for children while they are sleeping?
Answer:
It is good that your child is receiving Tamiflu treatment after their flu diagnosis. Based on the situation you described, your child appears to be following a very normal pattern of recovery.
[Sleeping Temperature Patterns]
• Normal sleeping temperature for children: 36.5°C – 37.5°C
• Your child's current temperature: 36.9°C – 37.1°C (This is well within the normal range)
• The temperature of 37.3°C right before falling asleep is also completely normal.
• Generally, a person's body temperature drops by about 0.5°C to 1°C during sleep compared to when they are awake.
[The Flu Recovery Process]
Even after starting Tamiflu, the influenza virus can remain in the body for about 5 to 7 days. The wet cough and hoarse voice are part of the natural healing process as the inflammation in the airways resolves. It is common for these respiratory symptoms to last for 1 to 2 weeks, even after the fever has fully subsided.
[Current Home Care Management]
Complete the full 5-day course of Tamiflu (please do not stop the medication early, even if the fever is gone).
Use a humidifier in the room and encourage your child to drink plenty of water.
Slightly elevate your child's head with a pillow while they sleep to help alleviate the cough.
Ensure they get plenty of rest.
⚠️ When to see a doctor again:
Please take your child back to the clinic or hospital if:
• A high fever of 38.5°C or higher returns.
• They experience difficulty breathing or complain of chest pain.
• Their symptoms worsen after 3 days instead of improving.
Your child is currently recovering smoothly, so you can rest assured. Continue with the supportive care at home, and consult your pediatrician if any of the warning signs above occur.
