A school in Kent has introduced 'Covid-style' rules to tackle the Strep A infection sweeping the nation.
A five-year-old girl, from Belfast, Northern Ireland, became the ninth child in the UK to die from the infection on Monday.
Now teachers have started to take coronavirus-style precautions in a bid to stop it from spreading among students.
Classroom "bubbles" have been reintroduced at Temple Grove Academy where two pupils have been infected with Strep A.
PE and assemblies have been cancelled, which avoids large gatherings, and lunch will be provided in classrooms instead of a communal hall.
Headteacher Isabel Ramsay wrote to parents informing them of the cases and of the measures in place to help keep their children safe.
She explained that the school, in Tunbridge Wells, Kent, was reverting to "similar protocols that were in place during Covid".
"There will be no PE or music, and playtime will be separated into zones to keep classes in their bubbles," Ms Ramsay said in her letter.
"There will be no assemblies. Please do not come to school for any assembly you were invited to as they will not be running this week.
"Further information will be communicated on Friday."
Ms Ramsay told parents to "remain vigilant" for any of the symptoms, referring them to guidance enclosed with the email.
"It is really important to be vigilant and inform us if you think your child is presenting with any of the symptoms alongside contacting your GP for antibiotics if necessary and keeping your child at home along with any siblings," she wrote.
One parent praised staff for "acting fast" and going "above and beyond to support those affected" at school for three to 11-year-olds.
"The school have acted fast and have implemented this," they said.
"Unlike any other school, Temple Grove has gone above and beyond to support those affected and to keep the children safe.
"I fully trust the senior leadership team to look after the welfare of the children and prioritise this.
"It’s a worrying issue, however parents should remain calm and seek medical advice as soon as the symptoms show."
Group A Strep bacteria can cause many different infections ranging from minor illnesses to deadly diseases including impetigo, scarlet fever and strep throat.
While the vast majority of infections are relatively mild, the bacteria can sometimes cause a life-threatening illness called invasive Group A Streptococcal disease.
Scarlet fever is usually a mild illness, but it is highly infectious.
Parents are being urged to look out for symptoms in their child such as a sore throat, headache, and fever along with a fine, pinkish or red body rash with a sandpapery feel.
The rash can be more difficult to detect visually on darker skin but will have a sandpapery feel.
Parents of children with scarlet fever are advised to keep them at home for at least 24 hours after the start of an antibiotic treatment to avoid the spread, according to the government website.
