ABCs Case Definition
Invasive group A streptococcal disease: isolation of group A Streptococcus from a normally sterile site or from a wound culture accompanied by necrotizing fasciitis or streptococcal toxic shock syndrome in a resident of a surveillance area in 2008.
ABCs Methodology
ABCs personnel routinely contacted all microbiology laboratories serving acute care hospitals in their area to identify cases. Standardized case report forms that include information on demographic characteristics, clinical syndrome, and outcome of illness were completed for each identified case. Strains were emm typed at CDC. Regular laboratory audits assessed completeness of active surveillance and detected additional cases.
All rates of invasive group A streptococcal disease were calculated using population estimates for 2008. For national estimates of cases, race- and age-specific rates of disease were applied from the aggregate surveillance area to the age and racial distribution of the 2008 U.S. population. Cases with unknown race were distributed by site based on reported race distribution for known cases within the eight age categories.

Potentially preventable invasive group A streptococcal disease
During 2008, 2 cases (aged 41 and 79 years) of invasive GAS disease and 1 death (aged 41 years) were detected in patients with varicella.
