Question:
If my child gets tonsillitis, will they always have a fever? I am curious if a fever is a mandatory symptom of tonsillitis.
Answer:
No, it is possible for a child to have tonsillitis without developing a fever.
The presence of a fever often depends on the cause of the infection:
Bacterial Tonsillitis
This type typically causes a high fever (38.5°C or higher) along with severe throat pain and significant pain when swallowing.
Viral Tonsillitis
This type may present with a mild fever or no fever at all, causing only mild throat discomfort. It is also commonly accompanied by cold symptoms like a runny nose and cough.
When to Seek Medical Care
Please visit a pediatrician for an evaluation on the same day if your child experiences any of the following:
A high fever (38.5°C or higher) accompanied by severe throat pain to the point where they cannot swallow saliva.
Severe swelling on only one side of the throat.
Drooling or difficulty breathing.
Symptoms that persist or worsen for more than 3 days.
If your child only has a mild fever and slight throat discomfort, you can observe them at home for 2 to 3 days. During this time, ensure they stay well-hydrated and offer them soft, easy-to-swallow foods. If you are ever unsure about your child's condition or if their symptoms fail to improve, please consult your pediatrician for a proper examination.
