As Somercotes Academy is a relatively small school, this involves the whole of Year 10.
Frances Green, Principal of Somercotes Academy, said: “Letters have been sent to all parents and carers of those affected.
“The Academy remains open to all other year groups and pupils should still attend if they remain well and have not been asked to isolate.
“We have followed national public health guidance around preventing the spread of coronavirus in school.
“Social distancing, frequent hand washing, wearing of face masks in communal areas, and regular cleaning is being rigorously practised right across the Academy, and we have robust risk assessments in place.”
As reported earlier this week, eight students had already been asked to self-isolate as a precaution after one member of staff tested positive for Covid-19.
