GUIDANCE is being given to schools in Denbighshire after a rise in infections caused by the Strep A bacteria.

Across the UK at least six children have died with an invasive form of the Strep A bacterial infection in recent months, with a seventh possible case reported at the weekend.

Denbighshire County Council has passed on guidance to schools from Public Health Wales (PHW) in regards to Scarlet Fever and invasive Streptococcal Disease.

A spokesperson for the local authority said: "Guidance provided to schools includes: Staff should be aware of the possibility of this infection in children who become ill with a fever, sore throat or rash; Parents of unwell children should be advised to seek medical advice for diagnosis and treatment; A person with scarlet fever should withdraw from your setting for 24-hours after the commencement of appropriate antibiotic treatment; Where there are two or more cases of scarlet fever in your setting within the same 10-day period, please notify the Health Protection Team [0300 00 300 32] for further guidance.

"Scarlet fever circulating at the same time as chickenpox or influenza can increase the risk of invasive disease - please report this to the Health Protection Team as above.

"Good hand hygiene and avoidance of spread of respiratory secretions as per influenza: 'catch it, bin it, kill it', which can help to prevent the spread of infection."

There has been an increase in scarlet fever this year. In the UK, there were 1,512 notifications of scarlet fever between January and October 2022, compared to 948 in the same period in 2019. 

PHW is reminding parents that cases of invasive group A streptococcal infection (iGAS) remain rare in Wales, and that children have a very low risk of contracting the disease.

In most cases, infection with streptococcal A causes scarlet fever, usually a mild illness.

Dr Graham Brown, Consultant in Communicable Disease Control for PHW, said: “While we understand that parents are likely to be worried by reports they are seeing related to iGAS, the condition remains rare.

“Cold and flu like symptoms are very common at this time of year, especially in children.  Most will have a common seasonal virus, which can be treated by keeping the child hydrated, and with paracetamol.

“Some children with cold and flu like symptoms - sore throat, headache, fever - may be experiencing some of the early symptoms of scarlet fever, which also circulates at this time of year.  These children will go on to develop scarlet fever specific symptoms, including a fine pink-red rash that feels like sandpaper to touch, and parents should contact their GP.

“While scarlet fever is more concerning, it is still usually a mild illness from which most children will recover without complications, especially if the condition is properly treated with antibiotics.

“In very rare cases, group A streptococcal infection can cause iGAS, a rare complication which affects fewer than 20 children in Wales each year.  Although iGAS is a worrying condition, the majority of these children will recover with proper treatment.

“The best thing that parents can do is to provide the care they would usually provide for a child with cold and flu like symptoms, but to familiarise themselves with the symptoms of scarlet fever and iGAS as a precaution.

“It is also important that children from two years upwards are protected from seasonal flu, and have the vaccine.”

Symptoms of scarlet fever

The symptoms of scarlet fever include a sore throat, headache, fever, nausea and vomiting.  This is followed by a fine red rash, which typically first appears on the chest and stomach, rapidly spreading to other parts of the body. Older children may not have the rash. 

On more darkly pigmented skin, the scarlet rash may be harder to spot, but it should feel like 'sandpaper'.  The face can be flushed red but pale around the mouth.

Parents who suspect their child has symptoms of scarlet fever are advised that they should:

  • Contact their GP, visit 111.wales.nhs.uk, or call NHS 111 Wales as soon as possible
  • Make sure their child takes the full course of any antibiotics prescribed by the doctor
  • Keep their child at home, away from nursery, school or work and follow any guidance provided by their GP on how long they should remain absent from these settings.

Symptoms of iGAS

  • Fever (a high temperature above 38°C)
  • Severe muscle aches
  • Localised muscle tenderness
  • Redness at the site of a wound.

Parents are being advised to contact their GP or get medical advice straight away if they think their child has any of the signs and symptoms of iGAS disease.
