Reporting for 24 and 31 December

On 24 December a full statistical bulletin is not available and instead a reduced commentary detailing the main points can be found below. This reduced format will also be adopted for publication on 31 December.

Alongside this publication all standard data tables for NHS Test and Trace are available on the weekly collection page. This includes data tables for NHS Test and Trace, regional contact tracing, demographic and regional information for people tested and people testing positive and pillar 2 tests conducted.

NHS Test and Trace will return to a standard reporting from 7 January. For more information on the statistics detailed below see the NHS Test and Trace statistics methodology document.

Main points

Testing in England

People tested, England

1,988,971 people were tested at least once in England between 10 December and 16 December for COVID-19^{[footnote 1]}, a 12% increase compared to the previous week.

173,875 people tested positive for coronavirus (COVID-19) at least once^{[footnote 1]} in England between 10 December and 16 December. The number of people testing positive this week has increased by 58% compared to the previous week with 8.7% of people tested testing positive, a rise from the 6.2% reported the previous week.

A total of 15,256,815 people have been tested at least once since testing began and 1,501,440 people have tested positive for COVID-19^{[footnote 2]} at least once^{[footnote 3]} during the same period^{[footnote 4]}.

Pillars 1 and 2 testing turnaround times, England

Between 10 December and 16 December, 93.9% of pillar 1 test results were made available within 24 hours. This has remained broadly consistent since Test and Trace began but is at its highest in the latest week.

Turnaround times for pillar 2 (virus testing for the wider population) for all in-person testing routes^{[footnote 5]} got shorter between mid-October and the beginning of December, however they have notably increased in the latest week. Turnaround times for satellite and home tests have also increased over the past 2 weeks after decreasing since mid-November.

For all routes combined, 18.6% of tests from all test sites were received within 24 hours of a test being taken. If we consider the day the test was taken, 37.1% of tests results were received the next day after the test was taken compared to 51.7% the previous week.

In the most recent week, for in-person tests (local test sites, mobile testing units and regional test sites), 34.1% were received within 24 hours. If we consider the day the test was taken, 61.0% of in-person tests results were received the next day after the test was taken compared to 91.8% the previous week.

For satellite test centres, 91.1% were received within 3 days after the day they were taken compared to 93.4% in the previous week. In the most recent week, approximately 90% of tests from satellite test centres were care home tests, and therefore removing the 10% of tests from other sites does not substantially change the turnaround figures.

Distance to in-person testing sites for booked tests, pillar 2, England

Between 10 December and 16 December, the median distance was 2.3 miles which has remained broadly consistent since mid-October.

Contact tracing in England

Positive cases transferred to NHS Test and Trace

139,332 people were transferred to the contact tracing system in the latest week, a notable increase from the previous week. The number of people transferred is over 15 times higher than the number transferred at the end of August.

Of the people transferred, 122,779 (88.1%) were reached, 14,749 (10.6%) were not reached and 1,804 (1.3%) had no communication details provided. The proportion of people reached has remained broadly similar over the past 7 weeks. Since Test and Trace launched, 84.8% of all cases have been reached.

Of the cases reached which were not managed by local HPTs between 10 December and 16 December, 47,243 (40.0%) were reached online and 70,827 (60.0%) were reached via the phone. Since Test and Trace began, 39.2% were reached online and 60.8% were reached by phone.

In the most recent week, the median number of contacts provided per case managed by local HPTs was 12, a slight increase from the previous week. For cases not managed by local HPTs the median was 2, and this has been approximately constant since the start of Test and Trace.

Between 10 December and 16 December, 77.3% of cases transferred (91,258) were reached within 24 hours. The proportion of people reached within 24 hours has been approximately consistent across the past 7 weeks.

Close contacts identified by NHS Test and Trace

Between 10 December and 16 December, 287,756 people were identified as recent close contacts, of which 266,549 (92.6%) were reached and told to self-isolate and 21,207 (7.4%) were not reached. Considering only the contacts where communication details were provided, 96.5% were reached and told to self-isolate in the most recent week. This is consistent with 96.6% in the previous week.

Since Test and Trace launched 83.2% of close contacts for whom contact details were provided have been reached.

Of the contacts reached who were not managed by local HPTs, and who weren’t a household contact told to self-isolate by their case, between 10 December and 16 December, 27,084 (54.9%) were reached online and 22,241 (45.1%) were reached via the phone^{[footnote 6]}.

Between 10 December and 16 December, 97.5% of contacts who weren’t managed by local HPTs were reached and told to self-isolate within 24 hours of being identified compared to 97.3% in the previous week.

NHS COVID-19 app in England and Wales

As of 16 December, the app has been downloaded 20,739,925 times and 775,191 QR posters have been generated through the GOV.UK coronavirus QR poster service. These figures cover both England and Wales.

Further information

The purpose of this publication is to provide a weekly update on the implementation and performance of NHS Test and Trace in England and Testing in the UK. Data collected for NHS Test and Trace is primarily for operational purposes and was not designed to track the spread of the virus. Studies into the spread of the virus in the UK are carried out by the Office for National Statistics (ONS). A full explanation of the data sources, terminology and methods used to produce these statistics can be found in the additional NHS Test and Trace statistics methodology document.

In addition to routine revisions, figures for the total number of people tested and testing positive at least once since testing began, which were unavailable last week, are now available. The full revised back series is published in the ‘table 2’ tab of the NHS Test and Trace data tables on the weekly collection page.

1. Deduplicated for the reporting week. For information on how the number of people are tested and tested positive in a reporting week is measured see the NHS Test and Trace statistics methodology. ↩ ↩²

2. Includes a small number of people who had a test under pillar 4 (serology and virus testing for national surveillance). ↩

3. Deduplicated since testing began and the end of the most recent reporting week. People testing positive multiple times in this time period will only be counted once. See NHS Test and Trace statistics methodology for more information. ↩

4. Note that these figures may not always align with other published figures for people tested and people tested positive for COVID-19 under pillars 1 and 2 due to the timing of data cuts. ↩

5. Based on the median turnaround time for in-person tests. ↩

6. The number of contacts reached by the phone and online will not sum to the total number of contacts reached not managed by local HPTs. This is because household contacts where the case has told them to self-isolate are not included, and for some contacts the tracing route is unknown. ↩
