Group A Streptococcus (GAS) is the name given to a type of bacteria sometimes found in the throat or on the skin, it can cause mild illness such as a sore throat.
Rarely, the bacteria can cause severe and life-threatening infection known as invasive Group A Strep (iGAS). These serious infections are caused by the bacteria getting into parts of the body where it is not normally found, such as the lungs or bloodstream. This can happen when a person has sores or open wounds that allow the bacteria to get into the tissue, breaches in their respiratory tract after a viral illness, or in a person who has a health condition that decreases their immunity to infection.
Although iGAS is uncommon, there has been an increase in cases this year, particularly in children under 10 years of age.
What to look out for
GAS infections cause various symptoms such as sore throat, fever, chills and muscle aches.
As a parent, if you feel that your child seems seriously unwell, you should trust your own judgement.

How is Group A Strep transmitted?
GAS can be passed from person to person by close contact such as kissing or skin contact.
Most people who come into contact with Group A Strep remain well and symptom free, some get mild throat or skin infections. You can reduce the risk of picking up Group A Strep by always washing your hands thoroughly for 20 seconds, using a tissue to catch coughs and sneezes, and keeping away from others when feeling unwell.
