Streptococcal pharyngitis, or strep throat, is an acute infection and inflammation of the pharynx that affects both children and adults. The most common bacterial etiology of pharyngitis is group A beta-hemolytic Streptococcus (GABHS, or Streptococcus pyogenes). The infection is transmitted via respiratory secretions.

  • Responsible for 5% to 20% of cases of pharyngitis in adults.
  • Responsible for 15% to 30% of cases of pharyngitis in children.
  • Most commonly occurs in children between 5 and 15 years of age.
Symptoms (Often Abrupt Onset):
  • Pain or difficulty swallowing
  • Fever
  • Chills
  • Malaise
  • Headache – Frequently frontal in location
  • Younger children – Abdominal pain, nausea, and vomiting
  • Severe unilateral throat pain should raise concern for a peritonsillar or retropharyngeal abscess, especially if this symptom arises or progresses several days after onset of symptoms. Inability to swallow, or odynophagia, should raise concern for a peritonsillar or retropharyngeal abscess.
  • Pharyngeal erythema
  • Exudate (gray-white), tonsillar pillars or posterior pharynx; occasional palatine petechiae, erythema and edema of the uvula
  • Anterior cervical lymphadenopathy (classic angle of jaw)
  • Scarlet fever – Usually face sparing, punctate, erythematous, blanchable, sandpaper-like exanthem that may be accentuated in skin folds and creases (Pastia's lines) and may desquamate during convalescence; bright red tongue with inflamed papillae (strawberry tongue); erythematous pharynx and tonsils covered with exudate.
  • Children less than 3 years of age – Coryza, purulent nasal discharge, excoriated nares (streptococcosis), and generalized adenopathy.
Risk Factors:
  • Exposure to a person with known streptococcal pharyngitis.
  • History of acute rheumatic fever or rheumatic heart disease.
  • The incubation period is 24-72 hours.
  • In most people, fever resolves within 3-5 days, and throat pain resolves within 1 week, even without specific treatment.
  • Patients with untreated GABHS pharyngitis are infectious during the acute phase and for 1 week after.
  • Late winter and early spring are peak GABHS seasons.
Complications of GABHS Illness:
  • Bacteremia
  • Cervical lymphadenitis
  • Endocarditis
  • Fasciitis/myositis
  • Mastoiditis
  • Meningitis
  • Otitis media
  • Perianal dermatitis in children
  • Peritonsillar/retropharyngeal abscess (quinsy) – Patient has toxic appearance, "hot potato voice," fluctuant peritonsillar mass, and asymmetric deviation of the uvula.
  • Pneumonia
  • Sinusitis
  • Toxic shock
  • Post-streptococcal glomerulonephritis – Hematuria and edema with history of a recent streptococcal infection (elevated anti-streptolysin O titer).
  • Acute rheumatic fever – Major (carditis, polyarthritis, chorea, erythema marginatum, subcutaneous nodules) and minor (arthralgias, fever, elevated acute-phase reactants, prolonged PR interval).
  • Pediatric autoimmune neuropsychiatric disorders associated with streptococcal infection.
  • Post-streptococcal autoimmune dystonia secondary to striatal necrosis.
  • Post-streptococcal reactive arthritis.
  • Sydenham's chorea and other autoimmune movement disorders.
