Answer

According to a report from the Centers for Disease Control and Prevention (CDC), approximately 9,000-11,500 cases of invasive GAS disease (3.2-3.9 per 100,000 population) occur each year in the United States. Streptococcal TSS and necrotizing fasciitis each accounted for approximately 6-7% of cases. More than 10 million noninvasive GAS infections (primarily throat and superficial skin infections) occur annually. [18, 19]
