Year 10 Pupils at Tredegar Comprehensive School were asked to self-isolate after a pupil tested positive for Covid-19.
The pupils and other affected parties have been asked to self-isolate for 14 days as a precautionary measure in line with Welsh Government guidance. All other year groups will continue to attend school as planned.
Procedures are already in place within all Blaenau Gwent schools to limit group numbers and pupil contact, coupled with enhanced cleaning regimes. There is no need for anyone who has not been contacted to self-isolate or be unduly concerned.
All residents are encouraged to remain alert to Covid-19 and continue to follow national guidance to help combat the spread of the virus.
School staff remain vigilant to pupils displaying any symptoms, and are ready to take appropriate action. Parents, carers and guardians can support this by remaining alert and ensuring that children do not attend school if they develop any potential symptoms, however mild.
