A NUMBER of students at a Braintree secondary school are self-isolating after a child tested positive for coronavirus.

Notley High School confirmed on Tuesday a student had tested positive for the virus in a letter posted on the school's website.

Executive headteacher Rob James said in the letter: "We have been advised by Public Health England that there has been a confirmed case of Covid-19 within the school.

"We know that you may find this concerning but we are continuing to monitor the situation and are working closely with Public Health England.

"This letter is to inform you of the current situation and provide advice on how to support your child.

"Please be reassured that for most people, coronavirus will be a mild illness.

"The small number of students who have been in direct prolonged contact with the confirmed case will have received an individual letter and will be staying at home for 14 days.

"The school remains open and your child should continue to attend if they remain well."
