A Mt Aspiring College pupil is being treated for meningococcal disease in Dunedin Hospital.
In a letter to parents and pupils, Southern District Health Board medical officer of health Dr Marion Poore said the health board did not believe there was a increased risk to staff and pupils, but people did need to be aware of the symptoms and signs of meningococcal disease.
Close contacts of the pupil had already been identified and been offered antibiotics to reduce the risk of contracting the disease.
Principal Wayne Bosley said the school had been advised to continue as usual and to reassure and support the pupils.
It was a difficult time for the school community and everyone's thoughts and wishes were with the pupils and her family, Mr Bosley said.
