There has been a confirmed case of Covid-19 at Malmesbury School.
Those who have been in direct, prolonged contact with the confirmed case will be self-isolating for 14 days.
The school remains open for everybody else.
A letter sent to parents yesterday by headteacher Rupert Moreton stated: “We are continuing to monitor the situation and are working closely with Public Health England.”
The school is the latest to confirm coronavirus cases. A pupil and teacher from Sir William Romney’s School in Tetbury have also recently tested positive.
