Jamie Greene’s first point was about the number of tests that have been carried out. The number of pupils in the 12 to 17 age group who tested positive was 77 and the number who tested negative was 11,208. In the five to 11-year-old category, 40 pupils tested positive and 28,664 tested negative. The positivity rate for five to 11-year-olds was 0.1 per cent. The positivity rate for the 12 to 17 age group was 0.7 per cent.

Full contact tracing is undertaken for all positive cases that are detected, and I pay tribute to the enormous industry that is put into that effort by the contact tracers. They have a really difficult job to do; they do it with proficiency and accuracy, and comprehensively.

On Jamie Greene’s other point, in relation to the work that is carried out in schools, every effort is made to understand where infection has come from. On the evidence that I have seen, the virus is contracted mostly in household settings—not in every case, but that is the predominant explanation. It may also involve international travel, which has resulted in quite a number of the cases with which we are wrestling.
