What is it Group Strep A?

Group Strep A is a bacterial type of germ that can cause scarlet fever. These bacteria also
cause other respiratory and skin infections such as strep throat and impetigo (a skin infection).
These are usually mild illnesses, which although highly infectious, can be treated at home with
In very rare occasions, the bacteria can get into the bloodstream and cause an illness called
invasive Group A strep. Whilst still uncommon, there has been an increase in invasive Group
A strep cases this year, particularly in children under 10.


Look out for symptoms in your child, which include:

  • Sore throat
  • Headache
  • Strawberry tongue or tonsils (swollen or bumpy or covered in white spots)
  • A fine, pinkish or red body rash with rougher skin that feels like sandpaper. On darker skin
    the rash may be more difficult to see
  • If your child is under 3 months old and has a temperature of 38°C or is older than 3 months
    and has a temperature of 39°C or higher (if you have a thermometer to check)
  • If your child feels hotter than usual when you touch their back or chest or feels sweaty (if
    you don’t have a thermometer to check)
    Seeking help
    Contact NHS 111 or your GP if you suspect your child has scarlet fever, because early
    treatment with antibiotics is important to reduce the risk of complications, such as pneumonia
    or a bloodstream Infection.
    If your child has scarlet fever, keep them at home until at least 24 hours after the start of
    antibiotic treatment to avoid spreading the infection to others.

  • Your baby feels hotter than usual when you touch their back or chest, or feels sweaty

    Spread and prevention
    Group A strep is spread by close contact with an infected person. It can be passed on through
    coughs and sneeze or from a wound. It’s important to:
  • Teach your child to wash their hands properly with soap and warm water for 20 seconds
  • Teach your child to catch coughs and sneezes into a tissue
  • Keep your child away from others when they are feeling unwell
