Throat pain is another common reason for primarycare visits, especially around the autumn and spring months. While pharyngitis is the predominant reason for throat pain, it could also be due to conditions such as postnasal drip, peritonsillar abscesses, epiglottitis, or infectious mononuclesosis. A careful history collection and a physical examination are important for making appropriate clinical decisions. Pharyngitis is caused by virus 90% of the time. Group A B hemolytic streptococcus (GABHS) causes 20% to 40% of pharyngitis cases in pediatrics and 5% to 15% in adults. Streptococcal pharyngitis is common in patients between 5 and 15 years old and rare in patients under 3 years old. Timely assessment and management are essential to prevent complications associated with GABHS. Similarly, viral pharyngitis must be distinguished from GABHS to prevent antibiotic overuse.
Collect a history onthe throat pain’s duration, any trouble breathing, fever, neck stiffness, otalgia, sinus pressure, past history of throat infection, chronic carriers of GABHS, sick contacts, and dysphagia.
Check the temperature. Are patients alert and oriented?
Are there tonsillar swelling or palpable anterior cervical nodes?
Is there any respiratory distress orairway occlusion?
Complete ENT examination to r/o AOM, sinusitis
Any neck stiffness, rashes, or facial swelling?
Any Signs and symptoms of viral illness?
A throat culture is the golden test for confirming GABHS infection. However, it may take 48 hours to obtain the result, which is a major drawback. Rapid antigen dip tests are available for office use to identify GABHS.They have a high specificity but low sensitivity. There are several clinical-decision criteria usedto predict GABHS’s possibility, such asCentor, modified Centor (McIsaac), Breese, Wald, Attia, FeverPAIN, and Joachim. Sudden-onset sore throat, odynophagia, fever, and the absence of viral URTI signs and symptoms (cough, rhinorrhea, hoarseness, oral ulcers, or conjunctivitis) are symptoms supporting bacterial etiology. Pharyngeal and tonsillar erythema, tonsillar hypertrophy with or without exudates, palatal petechiae, anterior cervical lymphadenopathy, and scarlet form rash (scarlet fever) are clinical signs that indicate GABHS pharyngitis. Patients who indicate bacterial etiology will require antibiotic treatment. Clinicians must perform a rapid antigen dip test or throat culture when possible to confirm the diagnosis. Children with persisting clinical s/s of pharyngitis but a negative rapid testing should have afollow-up throat culture. When untreated, strep throat spontaneously resolves in most of the cases; however, it increases the risk of complications, such as rheumatic fever, mastoiditis, and peritonsillar abscess. According to CDC’s recommendation, people with group A strep pharyngitis or scarlet fever should stay home from work, school, or daycare until they are afebrile and after24 hours of appropriate antibiotic therapy (2).
Modified Centor Score
|Temperature above 38 C||1|
|Absence of cough||1|
|Swollen, tender anterior cervical node||1|
|Tonsillar swelling or exudate||1|
|Age 3- 14 years||1|
|Age 15-44 years||1|
|Age above 45 or above||1|
If total score is -1 to 1- Provide symptomatic treatment
Score 2 and above- Do RADT or throat culture, if positive, treat with antibiotic (4)
Penicillin is the treatment of choice. To get a detailed list of pharmaceutical agents and dosages, please follow the link. Corticosteroid has only a weak recommendation forstreptococcus pharyngitis management (4).

Chronic carriers: Asymptomatic group A strep carriers usually do not require treatment as it is unlikely for them to develop any suppurative or nonsuppurative complications; similarly, they are very unlikely to transmit GABHS to others.
Avoid throat swabbing if an epiglottitis is suspected.
If a patient with throat pain develops diffused rashes after penicillin treatment, rule out EBV.
Recommend NSAIDs for pain management if viral pharyngitis is diagnosed.
Benzydamine oral rinse has been shown to significantly improve dysphagia and throat pain (5).
