Document Overview
negative results in children should often be followed by a confirmatory culture (Pellegrino et al., 2023). The major reasons to diagnose and treat GAS pharyngitis include reducing the duration and severity of symptoms, preventing complications such as acute rheumatic fever, and limiting transmission within the community. Penicillin or amoxicillin remains first-line treatment due to its narrow spectrum, safety profile, and low cost, with macrolides, cephalosporins, or clindamycin reserved for those with penicillin allergies. Adjunctive therapy with analgesics like acetaminophen or NSAIDs is often useful for symptomatic relief, while corticosteroids are generally not recommended except in severe cases where airway compromise exists (CDC, 2024). The differential diagnosis for acute sore throat is broad, encompassing viral pathogens adenovirus, Epstein-Barr virus/mononucleosis, and influenza, as the most common overall cause in all ages, but also includes other bacterial etiologies group C or G Streptococcus, Neisseria gonorrhoeae, and noninfectious causes, such as allergies or mechanical irritation. Viral pharyngitis often presents with cough, rhinorrhea, conjunctivitis, or oral ulcers, and does not typically require antibiotic therapy (Mustafa & Ghaffari, 2020). Recent guidelines and peer-reviewed articles emphasize the necessity of antimicrobial stewardship: laboratory confirmation before therapy, judicious antibiotic use, patient education about self-limited nature of most sore throats, and infection control measures such as hand hygiene. Continued investigation is ongoing into rapid diagnostic advances and artificial intelligence tools for better accuracy and efficiency in the diagnosis and management of acute pharyngitis. Willis, B.
