How long does a child's tonsillitis cause high fever?

Patient's question:

My child is four years old and has a fever. They went to the outpatient clinic and were told it's tonsillitis with low-grade fever. How long does a low-grade fever last in children with tonsillitis?

Doctor's answer:

Appears to be an acute onset. The highest temperature can reach 39℃~40℃. It can last continuously for 3~5 days. Children may experience dry vomiting, convulsions due to high fever, or coma. The symptoms of the whole body show no specificity. It is always important to maintain a cheerful attitude and not burden oneself with too heavy thoughts. The physical condition of children is greatly related to psychological factors. If there is no relief or it worsens, it is necessary to go to the hospital promptly to identify the cause. It can be accompanied by chills, high fever, etc.
The symptoms of acute tonsillitis in adults are usually more severe. Some patients may experience headaches, reduced appetite, fatigue, inability to defecate, and pain in the waist, back, legs, and hands.
