Recent increases in serious illness among children caused by Group A Strep (GAS) have raised concerns.
This article explains what Group A Strep is, how it spreads, its symptoms, and when to seek medical care.

What Is Group A Strep (GAS)?
Group A Strep is a common bacterium often carried in the throat or on the skin without causing illness. However, it can lead to both mild and severe infections.
What Are the Symptoms of Group A Strep?
Milder infections caused by GAS include:
- Tonsillitis and sore throat (commonly known as Strep Throat).
- Skin infections such as cellulitis and impetigo.
- Scarlet fever, which is characterized by fever, flu-like symptoms, and a rough, sandpaper-like rash that appears 24–48 hours after initial symptoms.
For severe cases, Invasive Group A Strep (iGAS) occurs when the bacteria enter organs or the bloodstream, potentially becoming life-threatening. Another rare complication of GAS is rheumatic fever.
How Is a Group A Strep Test Done?
Doctors may use a swab test to diagnose Group A Strep infections, but this isn’t always required. Mild cases often resolve on their own or with a short course of antibiotics.
Prompt diagnosis and treatment with antibiotics are crucial, especially for conditions like Scarlet Fever, to prevent complications.
How Long Is Group A Strep Contagious?
Group A Strep spreads through close contact, particularly from coughs, sneezes, or wounds.
Without antibiotics, the bacteria can remain contagious for several days. With treatment, individuals typically become non-infectious within 24 hours.
Good hand hygiene is one of the best ways to reduce the spread of GAS. Teach children to wash their hands thoroughly and avoid sharing personal items like utensils or towels.
Spotting Scarlet Fever: Symptoms to Watch For
Recognizing Scarlet Fever early can help prevent more serious infections. Look for:
- Fever and flu-like symptoms.
- Sore throat and swollen neck glands.
- A rough, sandpaper-like rash starting on the chest and tummy, which can spread.
- On white skin, the rash appears pink or red.
- On brown and black skin, the rash may feel rougher but be less visibly noticeable.
If you notice these symptoms, contact NHS 111 or your GP promptly.
When to Seek Emergency Care
If your child seems very unwell or is showing signs of severe illness, trust your instincts and seek medical help immediately.
Contact NHS 111, visit your nearest emergency department, or call 999 if necessary. Early intervention is critical, especially for severe cases like iGAS.
In Summary
Group A Strep is a common bacterium that usually causes mild illnesses but can occasionally lead to severe complications.
Understanding its symptoms, how it spreads, and when to seek help can make a significant difference in protecting your family. For further information, check the official resources below:
