Acute and chronic pharyngitis across the lifespan

Area of Science:

• Internal Medicine
• Infectious Diseases
• Family Medicine

Background:

• Pharyngitis, or sore throat, is commonly caused by benign infections but can indicate serious illness.
• Viral infections are the most frequent cause of pharyngitis, but Group A beta-hemolytic streptococcus (GABHS) requires antimicrobial treatment.
• No single symptom definitively identifies GABHS, necessitating clinical evaluation.

Purpose of the Study:

• To outline diagnostic approaches for pharyngitis, emphasizing the identification of GABHS.
• To highlight the importance of prompt diagnosis and treatment of GABHS pharyngitis.
• To educate on the judicious management of pharyngitis to reduce complications and antibiotic misuse.

Main Methods:

• Review of clinical signs and symptoms suggestive of GABHS.
• Emphasis on physical examination and laboratory testing for diagnosis.
• Discussion of the clinical implications of untreated or misdiagnosed pharyngitis.

Main Results:

• Sudden onset sore throat with fever and tender cervical lymph nodes, without cough, suggests GABHS in adults and possibly children.
• Accurate diagnosis aids in reducing missed school/work days and transmission.
• Proper management prevents Acute Rheumatic Fever (ARF) and inappropriate antibiotic use.

Conclusions:

• Prompt identification and treatment of S. pyogenes (GABHS) are vital for patient outcomes.
• Clinical assessment combined with laboratory tests aids in diagnosing acute and chronic pharyngitis.
• Public and clinician education on judicious pharyngitis management reduces costs and antibiotic exposure.
