- Reopening schools without better test and trace ‘threatens second wave’
Reopening schools without an improvement in test and trace could result in a second coronavirus wave more than twice the size of the first, a Lancet study suggests.
Researchers said pubs may have to be closed or millions of people urged to work from home if significant progress in tracking the spread of the virus is not made in the next month.
The study, by University College London and the London School of Hygiene and Tropical Medicine, simulated how the virus might spread when schools open at the start of September. It found that, if test and trace was more successful – so that 68 per cent of the contacts of positive cases were traced – the spread could be held in check.
Researchers warned that just 50 per cent of contacts of positive cases are currently reached. They said only one in seven infections in the country is being detected by the programme when its results are compared with surveillance sampling.
