Introduction
Low-grade fever refers to mild fever. If a child has purulent tonsillitis and persistent low-grade fever, this may be caused by the convalescent phase of inflammation, slightly impaired body heat dissipation, uncontrolled illness, viral infection, or systemic lupus erythematosus. Management should be based on the specific cause. Parents should promptly take the child to the hospital for evaluation, identify the underlying cause through medical examination, and receive appropriate treatment.
Low-grade fever refers to mild fever. If a child has pus-forming tonsillitis and continues to have a low-grade fever, this may be due to the inflammatory resolution phase, slightly impaired body heat dissipation, uncontrolled illness, viral infection, systemic lupus erythematosus (SLE), or other causes. Appropriate management should be based on the specific cause. Parents should promptly take the child to the hospital for evaluation and diagnosis to determine the underlying reason and receive proper treatment.
1. Inflammatory Resolution Phase
Pus formation in the tonsils is an inflammatory response. When the body's immune system begins to take effect and gradually controls the inflammation, a low-grade fever may occur. Ensure the child gets sufficient rest so the body has enough energy to fight the inflammation. Provide nutritious and easily digestible foods such as rice porridge or steamed egg custard to support recovery.
2. Slightly Impaired Heat Dissipation
The child may be dressed too warmly or be in a hot environment, leading to poor heat dissipation. Especially during episodes of pus-forming tonsillitis, when the body is already in an inflammatory state, temperature regulation may be somewhat affected, making low-grade fever more likely. Adjust the child’s clothing according to ambient temperature to avoid overdressing. Maintain good indoor ventilation and a comfortable room temperature.
3. Uncontrolled Condition
Pus-forming tonsillitis is usually caused by bacterial infection. If medications are not taken as prescribed during recovery, the condition may recur, primarily due to inadequate control of the infection. It is recommended to treat the child with antibiotics such as amoxicillin granules, roxithromycin granules, or cefaclor granules under a doctor’s guidance.
4. Viral Infection
During illness, the child's immunity is relatively low. If infected with another virus, persistent low-grade fever may develop. It is recommended to use medications such as acetaminophen suspension, oseltamivir phosphate granules, or ribavirin granules under medical supervision.
5. Systemic Lupus Erythematosus (SLE)
This is a systemic autoimmune disease caused by factors such as genetic predisposition and hormonal imbalances. If the child also has SLE, it may affect the immune system and lead to prolonged low-grade fever. Treatment should follow medical advice, including medications such as ibuprofen granules or methotrexate tablets.
During recovery, drinking more warm water can help accelerate metabolism and support the healing process.
