The performance of the NHS Test and Trace system continues to slide, with just one in seven people having a test at a centre getting their result back in 24 hours.
The new weekly data from the programme shows 15.1% of people who were tested for Covid-19 in England in the week ending October 14 at a regional site, local site or mobile testing unit – a so-called in-person test – received their result within 24 hours.
This is down from 32.8% in the previous week and is the lowest weekly percentage since Test and Trace began.
The figures also show a drop to 59.6% in the proportion of close contacts of people who tested positive who were reached.
This is the lowest weekly percentage since Test and Trace began and is down from 63% in the previous week.
For cases handled by local health protection teams, 94.8% of contacts were reached and asked to self-isolate in the week to October 14.
But for cases handled either online or by call centres, this figure was 57.6%.

The data also shows the positivity rate – the proportion of all tests returning a positive result – has climbed to 7.1% for the week, the highest since Test and Trace began.
According to criteria published by the World Health Organisation, a positivity rate of less than 5% is one indicator that the epidemic is under control in a country.
A total of 101,494 people tested positive for Covid-19 in England at least once in the week to October 14 – a rise of 12% in positive cases on the previous week.
The latest data shows that of 96,521 people transferred to the system, 80.7% were reached and asked to provide details of recent close contacts.
This is up slightly on 79.9% in the previous week.
