Invasive group A streptococcal (iGAS) disease is caused by infection with group A Streptococcus (Strep A) bacteria. Strep A bacteria usually cause mild disease such as sore throats (strep throat) and skin sores (impetigo); however, it can also cause iGAS.
iGAS is a severe disease which includes infection of the blood (sepsis), meningitis and pneumonia. It may also cause other serious illness such as toxic shock syndrome and necrotising fasciitis. People with symptoms of iGAS should seek medical care early.
