Streptococcus Disease, Invasive, Group A (GAS) (Streptococcus pyogenes)
1995 Case Definition

Clinical Description

Invasive group A streptococcal infections may manifest as any of several clinical syndromes, including pneumonia, bacteremia in association with cutaneous infection (e.g., cellulitis, erysipelas, or infection of a surgical or nonsurgical wound), deep soft-tissue infection (e.g., myositis or necrotizing fasciitis), meningitis, peritonitis, osteomyelitis, septic arthritis, postpartum sepsis (i.e., puerperal fever), neonatal sepsis, and nonfocal bacteremia.

Laboratory Criteria for Diagnosis

Isolation of group A Streptococcus (Streptococcus pyogenes) by culture from a normally sterile site (e.g., blood or cerebrospinal fluid, or, less commonly, joint, pleural, or pericardial fluid)

Case Classification

Confirmed

A case that is laboratory confirmed

Comments

The 1995 case definition appearing on this page was later re-published in the 1997 MMWR Recommendations and Reports titled Case Definitions for Infectious Conditions Under Public Health Surveillance.1 Thus, the 1995 and 1997 versions of this case definition are identical.
