• Tonsillopharyngitis is the acute infection of the pharynx, palatine tonsils, or both
• Also called strep throat, acute tonsillitis, pharyngitis or adenotonsillitis
• One of the most common diseases seen in primary care

• Main cause of acute tonsillopharyngitis
• Double-stranded DNA viruses (human adenovirus, Epstein-Barr virus), single-stranded RNA viruses [influenza, para-influenza, rhinovirus, enteroviruses, Coxsackie virus, coronaviruses, respiratory syncytial virus (RSV), human meta-pneumo-virus], and retroviruses [human immunodeficiency virus (HIV)] are among the viral causes

• Responsible for about 5-15% of clinic consultations for acute sore throat in adults 
• Most commonly caused by Gram-positive cocci known as S pyogenes
  • This organism exhibits beta-hemolysis on blood agar plates
  • Belongs to group A Lancefield classification system for beta-hemolytic strep infection
• Other bacterial causes include group C and G Streptococci, Haemophilus influenzae, Nocardia, Corynebacteria and Neisseria gonorrhoeae

• Spreads through person-to-person contact, usually through saliva or nasal secretions from an infected person
  • Primary reservoir of group A Streptococcus are the humans
• Easily transmitted in the schools, day care centers, and military training facilities
• Transmission via food is rare and if transmission happens, it is most of the time due to improper handling of food
• Pets and the use of household items such as plates and toys cannot transmit the disease

• Cough
• Diarrhea
• Hoarseness

Clinical Features Suggestive of Group A Beta-Hemolytic Streptococci (GABS) Pharyngitis

• The incubation period is approximately 2-7 days

Most Classic Symptoms

• Tonsillar swelling/exudates
• Tender anterior cervical lymphadenopathy
• Absence of cough
• Fever >38°C

Other Features of GABS Pharyngitis

• History of exposure
• Sudden onset of sore throat
• Pain on swallowing
• Petechiae on soft palate (“doughnut” lesions)
• Scarlet fever rash
• Beefy red, swollen uvula
• Tonsillopharyngeal inflammation and erythema with or without exudates
• Headache

• Abdominal pain
• Malodorous breath
