Of the 20,968 people assigned to England’s 25,000 contact tracers, only 10,058 have actually given information that the tracers could follow up (48 per cent).
In its report this week, the Department of Health said the people who were unable to give contact details were ones who had only come into contact with complete strangers, such as on the bus.
The staggering number suggests that an app – which automatically links people’s phones so it can alert people who don’t know one another – may be necessary for contact tracing to work perfectly.
From the infected people who have been successfully contacted themselves, two thirds of them were able to give details of one or more close contacts.
Between June 17 and the system’s launch at the start of the month, 15,225 confirmed coronavirus patients have been successfully reached by contact tracers.
But more than one in three – 5,167 people – were ‘not able’ to give details of a single person they may have come into close contact with. A further 5,062 people who tested positive could not be reached at all by contact tracers – who phone, text and email someone 10 times a day to get hold of them.
Today’s update revealed that a total of 134,893 people – people who have tested positive, and their contacts – have been in touch with NHS Test and Trace in three weeks.
One scientist said the statistics today were ‘worrying’ and 바카라사이트 could only be solved with better co-operation from the public – not by the Government.
Department of Health data shows that fewer than half of people referred to NHS Test and Trace so far have actually given details of any contacts they had before they were diagnosed
The Department of Health admitted in its report today that many people who were successfully contacted by Test and Trace, but didn’t give any details of contacts, simply didn’t know how to reach people they had been close to.
It said: 카지노사이트추천 ‘The number who were not able to give any recent close contacts refers to people who were successfully reached by NHS test and trace, but could not provide details of close recent contacts to pass on for further contact tracing (for example, 카지노사이트쿠폰 recent close contact with strangers on the bus).’
Until last week the NHS had been working on a mobile app which would automatically record and link the smartphones of people who came close to one another.
This would have allowed technology to keep records of people’s contacts, and could overcome the obstacle of people being unable to give details of strangers.
But the app was abandoned after ‘technical challenges’ during a trial on the Isle of Wight which revealed it could only spot four per cent of iPhones nearby.
Since test and 바카라 trace launched, only two thirds of people who picked up the phone have actually given any contact details for people they came close to.
When the number of infected people who couldn’t even be contacted is factored in, the proportion of people with Covid-19 giving useful information falls below 50 per cent
