CASES of scarlet fever have been confirmed at a school in Swindon.

The Dorcan Academy has written to parents after four people reported having the infection.

A spokesman said: "We have been advised to make you aware that there is currently a high level of infection amongst both students and staff.

"This has been reported to the UK health authorities in line with guidance.

"There is no need for alarm or for your child to be kept away from school at this time, unless they are unwell.

"We have stepped up infection control procedures in school and will keep you informed of any updates.

"Please ensure that you read the information. Thank you for your continued support."

The school has been contacted for further comment.

Scarlet fever and Strep A: Everything you need to know

The NHS advises people with scarlet fever to stay away from nursey, school or work until 24 hours after you take the first dose of antibiotics.

Symptoms include a sore throat, headache, and fever, along with a fine, pinkish or red body rash with a sandpapery feel.

Parents should contact NHS 111 or their GP if they suspect their child has scarlet fever because early treatment with antibiotics helps reduce the risk of complications such as pneumonia or a bloodstream infection.

It can be a serious illness, but thanks to antibiotics, it is easier to treat.

The UK Health Security Agency has seen an unexpected increase in the number of reported cases for this type of infection in the last few months, possibly due to high amounts of circulating bacteria and social mixing.

Scarlet fever is caused by the strep A infection.

Deputy director of the UKHSA Dr Colin Brown said: "We are seeing a higher number of cases of Group A strep this year than usual.

"The bacteria usually causes a mild infection producing sore throats or scarlet fever that can be easily treated with antibiotics.

"In very rare circumstances, this bacteria can get into the bloodstream and cause serious illness – called invasive Group A strep (iGAS).

"This is still uncommon; however, it is important that parents are on the lookout for symptoms and see a doctor as quickly as possible so that their child can be treated and we can stop the infection becoming serious.

"Make sure you talk to a health professional if your child is showing signs of deteriorating after a bout of scarlet fever, a sore throat, or a respiratory infection."

There were 851 cases reported up to the 46th week of this year, compared to an average of 186 for the preceding years.
