From BBC UK but of no interest to BBC England or BBC Scotland:

Researchers from UCL and the London School of Hygiene and Tropical Medicine used computer models to see how the virus might spread in the UK as pupils returned to the classroom and their parents were more able to go back to work or resume other activities.

They found fault and suggested that:

Current testing and contact tracing is inadequate to prevent a second wave of coronavirus after schools in the UK reopen.

However, on more thorough reading, it becomes apparent that this warning is only explicitly for England and the ‘UK’ Government:

‘Doesn’t look good enough’

However, the researchers said NHS test and trace in England was falling short.

They estimate only half of contacts are being traced and while it is harder to know the percentage of people being tested, they say this also appears too low.

“It is not achieving the levels we have modelled. It doesn’t look good enough to me,” said Prof Chris Bonell, from the London School of Hygiene and Tropical Medicine.

Dr Jasmina Panovska-Griffiths, from UCL, added: “With UK [English] schools reopening fully in September, prevention of a second wave will require a major scale-up of testing to test 75% of symptomatic infections – combined with tracing of 68% of their contacts, and isolation of symptomatic and diagnosed cases.”

No critical comments are directed at the test and trace systems in the three devolved areas, all of which are based on integration within existing public health bodies as opposed to the privatised model adopted in England..
