Strep A

Symptoms of a strep A infection
Common symptoms of strep A include:

flu-like symptoms, such as a high temperature, swollen glands or an aching body
sore throat (strep throat or tonsillitis)
a rash that feels rough, like sandpaper (scarlet fever)
scabs and sores (impetigo)
pain and swelling (cellulitis)
severe muscle aches
nausea and vomiting

Most strep A infections are not serious and can be treated with antibiotics.

But rarely, the infection can cause serious problems. This is called invasive group A strep (iGAS).

What to do if your child is unwell
It can be difficult to tell when a child is seriously ill, but the main thing is to trust your instincts.

You know better than anyone else what your child is usually like, so you’ll know when something is seriously wrong.

If your child does not seem to be seriously ill, you can usually look after them at home. They should feel better in a few days.

If they’re uncomfortable, you can give them children’s paracetamol or children’s ibuprofen. Check the leaflet to make sure the medicine is suitable for your child and to see how much to give them.

Urgent advice:

Get an urgent GP appointment or get help from NHS 111 if:
your child is unwell and is getting worse
your child is feeding or eating much less than normal
your child has fewer wet nappies than usual or is peeing less than usual, or shows other signs of dehydration
your baby is under 3 months and has a temperature of 38C, or is 3 to 6 months and has a temperature of 39C or higher
your child is very tired or irritable

It’s important to trust your instincts if your child is unwell. Get medical help if you think you need it.

Check symptoms on 111 online (for children aged 5 and over) or call 111 (for children under 5).

Immediate action required: Call 999 or go to A&E if:
your child is having difficulty breathing – they may make grunting noises, or you may notice their tummy sucking under their ribs
there are pauses when your child breathes
your child’s skin, tongue or lips are blue or grey – on black or brown skin this may be easier to see on the palms of the hands or soles of the feet
your child is floppy and will not wake up or stay awake

Treatments for a strep A infection
Most strep A infections can be easily treated with antibiotics.

If you or your child has a strep A infection, you should stay away from nursery, school or work for 24 hours after you start taking antibiotics. This will help stop the infection spreading to other people.

Serious strep A infections (invasive group A strep, iGAS) need to be treated in hospital with antibiotics.

How you get strep A infections
Strep A infections are spread by close contact with an infected person. They can be passed on through coughs and sneezes or from a wound.

In some people, the bacteria live in the body without causing symptoms or making them feel unwell. But they can still pass the bacteria on to others.

Things that might make you more at risk of strep A infections include:

a weakened immune system
open sores or wounds
some viral infections, such as a cold or flu

How to avoid getting infections
Infections like strep A can easily be spread to other people.

To reduce the chance of catching or spreading an infection:

wash your hands often with soap and water
cover your mouth and nose with a tissue when you cough or sneeze
bin used tissues as quickly as possible
