Group A streptococcal infections can cause a diverse variety of suppurative diseases and nonsuppurative postinfectious sequelae. The suppurative spectrum of group A streptococcal infection diseases includes the following:

  • Pharyngitis, with or without tonsillopharyngeal cellulitis or abscess;

  • Impetigo (purulent, honey-colored, crusted skin lesions);

  • Pneumonia;

  • Necrotizing fasciitis;

  • Cellulitis;

  • Streptococcal bacteremia;

  • Osteomyelitis;

  • Otitis media;

  • Sinusitis; and

  • Meningitis or brain abscess (a rare complication resulting from direct extension of an ear or sinus infection or from hematogenous spread).

The nonsuppurative sequelae of group A streptococcal infections include the following:

  • Acute rheumatic fever, defined by the Jones criteria;

  • Rheumatic heart disease—chronic valvular damage, predominantly to the mitral valve; and

  • Acute glomerulonephritis.
