The government's flagship coronavirus 'Test and Trace' system is still failing to reach a quarter of people who test positive, new figures show.
In the three weeks since the system launched on May 28, some 20,968 people in England tested positive for Covid-19 and were logged by contact tracers.
But just 15,225 (73%) were reached and asked to provide details of their recent contacts. Between them, they had just over 128,000 contacts, 89% of whom have successfully gone into isolation.
Yet a further 5,062 people who tested positive couldn't be reached despite having contact details. And another 681 did not have any details they could be contacted on.
