Tonsillitis is one of the most common illnesses in children. It occurs as a result of a viral or bacterial infection of the tonsils, which are two masses of lymphatic tissue located at the back of the throat. The tonsils play an important role in the body's immune defense, but when they become infected, they can cause bothersome symptoms that require prompt treatment to avoid complications. ⸻ Causes of Tonsillitis 1. Viral Infection (Most Common): • Such as cold and flu viruses. • Viral tonsillitis is often mild and resolves on its own within a few days. 2. Bacterial Infection: • Most commonly caused by Streptococcus pyogenes. • This type usually requires antibiotic treatment. ⸻ Symptoms of Tonsillitis in Children • Sore throat and pain. • Redness and swelling of the tonsils, sometimes with white or yellow spots (pus). • Difficulty swallowing. • Fever. • Headache. • Swollen lymph nodes in the neck. • Bad breath. • Loss of appetite. • Hoarseness or a change in voice tone. • Sometimes: Ear or abdominal pain, especially in younger children. ⸻ Diagnosis of Tonsillitis Doctors rely on: • Clinical examination: to observe the appearance of the throat and tonsils. • Throat swab: to detect streptococcal bacteria. • Blood tests: sometimes performed in unclear cases. ⸻ Treatment of Tonsillitis First: According to the cause 1.
