Group A streptococcus is a bacterium that people may carry in their nose, throat or on their skin without symptoms. 
If GAS does cause symptoms, most of the time it only causes mild illness, including strep throat.

Occasionally the bacterium can cause more severe infections. This happens when the bacterium gets into your blood, lungs, or muscles. This is called invasive group A streptococcal infection or iGAS.

The rarest, but most serious forms of iGAS, are:

  • Streptococcal toxic shock syndrome
  • Necrotizing fasciitis, often called flesh-eating disease
