|Definite||Either of the following: 1. The isolation of GAS from a normally sterile site (e.g., blood, cerebrospinal fluid, or other sterile fluid/tissue). 2. Clinical presentation of necrotizing fasciitis with evidence of GAS infection (e.g., the presence of typical gram-positive cocci on Gram stain or positive streptococcal serology).|
|Probable||Any of the following: 1. A classic presentation of necrotizing fasciitis without microbiological confirmation. 2. Cellulitis in a patient who is moderately or severely unwell (i.e., unwell and history of parenteral antibiotics and/or admission to hospital) and microbiological confirmation (i.e., group A streptococcal culture of swab or positive streptococcal serology). 3. Other clinically significant infection in a patient who is moderately or severely unwell (i.e., unwell and history of parenteral antibiotics and/or admission to hospital), in conjunction with positive group A streptococcal culture from deep wound swab or biopsy from surgical infection site.|
