Invasive Group A Streptococcal Infection (iGAS) 

Streptococcus A (Strep A)

Group A streptococcus (GAS) is a common bacteria. Lots of us carry it in our throats and on our skin and it doesn’t always result in illness. However, GAS does cause a number of infections, some mild and some more serious.

The most serious infections linked to GAS come from invasive group A strep, known as iGAS.
