The staff member had been working at the school for several months before becoming ill and was diagnosed with TB at the end of April.
All 84 pupils, aged 4 to 11, at Tan-y-Grisiau Primary School in Blaenau Ffestiniog and staff members were given skin-prick tests on 5 May to see if they were infected. Eleven children had a 'grade 1 result' which indicated possible exposure to the bacterium, according to Dr Robin Davies, consultant paediatrician with Gwynedd Community Health Trust.
The children have been X- rayed and given clinical examinations. None is said to be serious. The remaining children will be tested again next month to see if any have subsequently developed the infection.Reuse content
