1 in 560 positive in England, 1 in 300 in Wales (ONS survey just out).
School year 7 - 11 have the highest incidence, 1 in 200. The graph is an interesting shape, levelling off a bit last week- then I remembered it was half term of course.
Poor kids, especially the CEV/ CV ones.
There is also an echo of this curve in people aged 35-49, presumably parents and teachers.
