Two children have been treated for meningitis at a school in Crowthorne.

Safety advice has been issued to parents after one child aged three and another aged four were struck with the illness at Our Lady’s Preparatory School and Nursery in The Avenue, Crowthorne, Berkshire.

Public Health England has confirmed two children from the nursery have had confirmed cases of a meningococcal infection, which can cause meningitis as well as septicaemia.

Symptoms of the illnesses include fever, vomiting, delirium and extreme sleepiness.

Both can prove fatal if left untreated.

The outbreak is being handled by Public Health England, which is working closely with Our Lady’s Preparatory School and Nursery, Bracknell Forest Council, Wokingham Borough Council and NHS partners.

As a precaution, antibiotics and vaccines are being offered to children in the same age group and members of staff at the nursery to prevent the further spread of infection.

A spokeswoman for Public Health England insisted there is no need for anyone who attends or works at the nursery to change their daily routine.

Dr Kitty Mohan, consultant in Health Protection for Public Health England South East, said: "We understand that there will be concern among parents and staff following these cases and we’re following national guidelines to ensure close contacts are offered antibiotics to reduce the risk of the infection spreading.

"The best advice remains for everyone to be aware of and alert to the signs and symptoms of meningococcal infection.

"Early recognition of meningitis and septicaemia symptoms can greatly improve the outcome of the disease.

"Although meningococcal disease is uncommon, people should be aware of the symptoms which can include a fever, headache, rapid breathing, drowsiness, shivering, vomiting and cold hands and feet.

"It can also cause a characteristic rash which does not fade when pressed against a glass.

"People who are concerned about any of these symptoms should seek medical advice immediately by calling their GP or NHS 111.

"The Meningitis B vaccine has been introduced into the childhood vaccination schedule for children in England born on and after Friday, May 1, 2015.

"If you are unsure if your child has had the vaccine, please contact your GP."

Parents across the area including Reading, Berkshire are urged to be vigilant for any signs of the symptoms.
