Answer

Although no single finding or combination of physical findings distinguishes GABHS from a viral etiology, several findings are suggestive, including the following:

  • Enlarged tonsils

  • Pharyngeal erythema

  • Tonsillar exudates with necrotic crypts

  • Soft-palate petechiae

  • Tender cervical adenopathy

  • Scarlet fever rash (punctate erythematous macules and fine papules with reddened flexor creases and circumoral pallor), the so-called sandpaper rash

  • Conjunctivitis (more common with adenovirus infections)

GABHS pharyngitis is often associated with headache, pharyngeal exudate (see the image below), painful cervical adenopathy, gastrointestinal (GI) symptoms, chills, and high fever.
