Sore Throat Without Fever: Clinical Insights and Management
Introduction to Sore Throat Without Fever
Sore throat, or pharyngitis, is a common symptom that can occur with or without fever. While fever often accompanies infections, there are instances where a sore throat presents without an elevated temperature. Understanding the underlying causes and appropriate management strategies is crucial for effective treatment.
Common Causes of Sore Throat Without Fever
Viral Infections
Viral infections are a leading cause of sore throat without fever. These infections often present with mild symptoms such as pharyngeal erythema and mild tenderness of the anterior neck, without significant systemic involvement2 4. Unlike bacterial infections, viral pharyngitis typically does not require antibiotic treatment and resolves on its own with supportive care.
Allergic Reactions and Irritants
Exposure to allergens or irritants can also lead to a sore throat without fever. In such cases, the sore throat is often accompanied by other symptoms like nasal congestion or postnasal drip, but the absence of fever helps differentiate it from infectious causes1.
Diagnostic Approach
Clinical Examination
A thorough clinical examination is essential to identify the cause of a sore throat. Key findings may include pharyngeal erythema, mild tenderness of the anterior neck, and the absence of significant lymphadenopathy2 4. These signs help differentiate between viral and bacterial causes.
Rapid Antigen Detection Tests
For cases where bacterial infection is suspected, rapid antigen detection tests (RADTs) for group A streptococcus can be useful. However, a negative RADT in the absence of fever and other systemic symptoms often points towards a non-bacterial cause1 3.
Management Strategies
Symptomatic Treatment
For viral or non-infectious causes of sore throat, symptomatic treatment is the mainstay. This includes the use of analgesics, throat lozenges, and adequate hydration. Antibiotics are not indicated in these cases and should be avoided to prevent unnecessary side effects and antibiotic resistance2 4.
Monitoring and Follow-Up
Patients should be advised to monitor their symptoms and seek further medical attention if they develop additional symptoms such as high fever, significant lymphadenopathy, or persistent sore throat. This is crucial to rule out complications or secondary infections1 2.
Conclusion
Sore throat without fever is often due to viral infections or non-infectious causes such as allergies. A careful clinical examination and appropriate use of diagnostic tests can help identify the underlying cause and guide effective management. Symptomatic treatment is usually sufficient, and antibiotics should be reserved for confirmed bacterial infections. Regular monitoring and follow-up are essential to ensure patient recovery and address any emerging complications.

Diagnostic accuracy of Fever-PAIN and Centor criteria for bacterial throat infection in adults with sore throat: a secondary analysis of a randomised controlled trial
Both FeverPAIN and Centor criteria are insufficient for diagnosing streptococcal throat infections in adults without immediate antibiotics, but higher scores are associated with increased delayed prescriptions.
