Can Tonsillitis Cause Fever?


Yes, tonsillitis can cause a fever. Tonsillitis is an inflammation of the tonsils, which are two oval-shaped lymphoid tissues located at the back of the throat. It is most commonly caused by viral or bacterial infections.

When the tonsils become infected, the body’s immune response is triggered, leading to inflammation. This inflammatory response often results in symptoms such as:

  • Sore throat
  • Difficulty swallowing
  • Red and swollen tonsils
  • White or yellow patches or coatings on the tonsils
  • Enlarged and tender lymph nodes in the neck
  • Fever

Fever is a common symptom of tonsillitis, especially when the infection is caused by bacteria. The body raises its temperature as a natural defense mechanism to help fight off the infection. Fevers associated with tonsillitis are usually mild to moderate but can sometimes be higher in more severe cases.

It’s important to note that while tonsillitis caused by a viral infection may not require specific treatment and tends to resolve on its own, bacterial tonsillitis, such as that caused by group A streptococcus (strep throat), often requires antibiotic treatment to prevent complications and to shorten the duration of the illness.

If you or someone you know is experiencing symptoms of tonsillitis, including a fever, it is essential to seek medical evaluation and appropriate treatment. A healthcare professional can diagnose the cause of the tonsillitis and recommend the most suitable course of action to help manage the infection and relieve symptoms.
