Overview

Strep throat and tonsillitis both cause a sore throat and involve inflammation in the throat area, but their causes differ. Strep throat is a bacterial infection caused by Streptococcus pyogenes, while tonsillitis refers to inflammation of the tonsils, which can be caused by either viruses or bacteria. All strep throat is tonsillitis, but not all tonsillitis is strep. Strep throat typically presents with sudden severe sore throat, fever, and no cough, while viral tonsillitis may include cough and congestion.

Disease Summaries

Strep Throat: Strep throat is a bacterial infection caused by Streptococcus pyogenes (Group A Streptococcus). It primarily affects the throat and tonsils, leading to sudden and severe sore throat, pain with swallowing, fever, and swollen lymph nodes. It is most common in children and spreads through respiratory droplets. Unlike viral sore throats, strep throat typically does not include coughing or nasal symptoms.

Tonsillitis: Tonsillitis is infection of the tonsils and pharynx (back of the mouth), either by viruses or bacteria.

Treatment Approaches

Strep Throat Treatment Approaches

Strep throat is treated with antibiotics, usually penicillin or amoxicillin, to reduce symptoms, prevent complications, and limit contagion. Symptom relief may include over-the-counter pain relievers (acetaminophen or ibuprofen), hydration, and throat soothing remedies. Patients are typically no longer contagious after 24 hours of antibiotic therapy.

Tonsillitis Treatment Approaches

This condition may improve without treatment, especially if caused by viruses. The doctor may prescribe pain relievers, and in some cases antibiotics to fight a bacterial infection. Ensuring proper hydration is important as pain makes swallowing and drinking difficult.
