Data on UK tests, positive cases and deaths.

Breakdown of testing by testing strategy ‘pillars’:

• Pillar 1: swab testing in Public Health England (PHE) labs and NHS hospitals for those with a clinical need, and health and care workers
• Pillar 2: swab testing for the wider population, as set out in government guidance
• Pillar 3: serology testing to show if people have antibodies from having had COVID-19
• Pillar 4: serology and swab testing for national surveillance supported by PHE, ONS, Biobank, universities and other partners to learn more about the prevalence and spread of the virus and for other testing research purposes, for example on the accuracy and ease of use of home testing

More information can be found in the government's testing methodology document.

General notes

The source data this listing relates to is updated by PHE daily at 2pm London-time, or shortly after. The figures for test results and for deaths are compiled from different sources. This is why the figures for deaths are reported from an earlier point in time than the figures for test results.

Daily totals reflect actual counts reported for the previous day. Each day there may be corrections to previous reported figures. This means that previously published daily counts will not necessarily sum to the latest cumulative figure. It also means that today’s cumulative count may not match the previous day’s cumulative count plus today’s daily count.

Notes on deaths figures

From 29 April, figures for deaths include all cases where there is a positive confirmed test for coronavirus. The figures include deaths with lab-confirmed COVID-19 in all settings, not just those in hospital, and this provides us with a single figure on an equivalent basis for the whole of the UK.

These UK figures are compiled from validated data provided by each of the four nations of the UK. Figures from Health Protection Scotland, Public Health Wales and the Public Health Agency (Northern Ireland) have always included tested cases outside hospital. Figures for England from 29 April onwards are provided by Public Health England and draw together several different data sources, including data from NHS England and Improvement, to produce this broader measure.

This approach allows us to compile deaths data on a daily basis using up-to-date figures across all settings. The data includes deaths with lab-confirmed COVID-19 reported as at 5pm the previous day. The amount of time between occurrence of death and reporting in these figures may vary slightly and in some cases could be a few days, so figures at 5pm may not include all deaths for that day.

The PHE method draws on data from 3 data sources and individual records of deaths are included in the figures as soon as they are available in any of these 3 sources.

In addition to these figures, the Office for National Statistics (ONS) publishes weekly counts of deaths in which COVID-19 was mentioned on the death certificate. This publication is issued every Tuesday, starting on 31 March 2020. The ONS series includes cases in all settings, and also includes some cases where COVID-19 is suspected but no test has taken place. ONS detailed data covers England and Wales only, but from 28 April their publication includes a headline summary of registered deaths in the whole of the UK. Their report each Tuesday covers deaths registered up to 11 days before publication.
