Sore Throat Symptoms: Common Causes and Clinical Features
Sore throat, also known as pharyngitis, is a frequent symptom seen in both children and adults and can be caused by a variety of conditions. The most common causes are viral and bacterial infections, but non-infectious factors can also play a role 1467.
Viral and Bacterial Sore Throat Symptoms
Most sore throats are due to viral infections, which often come with additional symptoms like a runny nose and cough. Bacterial sore throats, especially those caused by Streptococcus pyogenes (group A strep), are more likely to present with fever, red and swollen tonsils, and swollen glands in the neck. In some cases, a skin rash may develop, known as scarlet fever. These symptoms are more common in children aged 5–15 years and tend to occur in winter or early spring 147.
Infectious mononucleosis, caused by the Epstein-Barr virus, is another common cause, especially in adolescents and young adults. It typically presents with sore throat, fever, malaise, and enlarged lymph nodes .
Other Causes and Chronic Sore Throat
Chronic sore throat is often due to non-infectious causes such as gastrointestinal reflux, autoimmune diseases, or, less commonly, malignancy. Infectious causes of chronic sore throat can include tuberculosis and fungal infections like Candida or Histoplasma .
Sore Throat in COVID-19
Sore throat can also be a symptom of COVID-19, though it is less common compared to fever and cough. In COVID-19, sore throat is usually mild and may be accompanied by other symptoms such as fatigue and nasal congestion 810.
Self-Assessment and Diagnosis of Sore Throat Symptoms
Patients can use clinical prediction rules like the Centor or FeverPAIN scores to assess the likelihood of a bacterial infection. These scores consider symptoms such as fever, swollen lymph nodes, tonsillar exudate (pus), and absence of cough. However, self-assessment of signs like swollen lymph nodes and throat inflammation can be challenging for many people 23.
Symptom Relief and Treatment
Most sore throats resolve on their own within a week. Over-the-counter pain relievers such as ibuprofen or paracetamol are recommended for symptom relief. Antibiotics are generally not needed unless a bacterial infection is strongly suspected or confirmed, as their benefits are modest and must be weighed against potential side effects and antibiotic resistance 359.
Aromatherapy has shown some benefit in reducing sore throat and fatigue in adults recovering from COVID-19, but more research is needed to confirm its effectiveness .
Conclusion
Sore throat is a common symptom with a wide range of causes, most often viral or bacterial infections. Key symptoms include throat pain, fever, swollen tonsils, and swollen neck glands, with additional features depending on the underlying cause. Most cases are mild and self-limiting, but persistent or severe symptoms may require further evaluation to rule out less common causes. Self-assessment tools can help guide management, but clinical judgment remains important, especially when considering the use of antibiotics.
