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.Some people are tested more than once for clinical reasons, therefore the number of tests completed is higher than the number of people tested. For serology testing (Pillar 4), some protocols allow for samples to be tested repeatedly. Samples are anonymised prior to sending to the lab for testing, therefore the identification of individuals tested is not possible in the current reporting process, and so the number of people tested is not reportedDaily 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. The figure for the number of “tests” excludes data from Northern Ireland.16 April notesThe difference between the cumulative numbers from today and yesterday for “number of tests” is 68 off the daily increase figures, this is due to PHEcorrecting some errors in their historical data.The difference between the cumulative numbers from today and yesterday for “number of positive cases” is 1 off the daily increase figures, this is due to Wales removing duplicates from their historic data.Incorporating figures on swab testing for critical key workersFrom 10 April, figures for positive tests include positive case results from swab testing for key workers and their households (pillar 2). Data on positive case results from swab testing for key workers and their households between 25 March and 9 April is available below.DatePositiveWed 25 March0Thurs 26 March0Fri 27 March5Sat 28 March10Sun 29 March69Mon 30 March46Tues 31 March241Wed 1 April243Thurs 2 April278Fri 3 April222Sat 4 April265Sun 5 April296Mon 6 April341Tues 7 April254Wed 8 April374Thurs 9 April331Notes on deaths figuresThe figures on deaths relate in almost all cases to patients who have died in hospital and who have tested positive for COVID-19. Slight differences in reporting in devolved administrations may mean that they include a small number of deaths outside hospital. The figures are compiled from validated data provided by NHS England and Improvement, Health Protection Scotland, Public Health Wales and the Public Health Agency (Northern Ireland).These figures do not include deaths outside hospital, such as those in care homes, except as indicated above. This approach allows us to compile deaths data on a daily basis using up-to-date figures. The data includes confirmed cases 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.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. It includes cases outside hospital and also some cases where COVID-19 is suspected but no test has taken place. ONS data will initially cover England and Wales only and will report on deaths registered up to 11 days before publication, so up to 20 March for their first release.Material published by PHEPHE updates a daily dashboard to show trends in UK data on positive tests and deaths and to provide confirmed cases in each local authority and NHS region in England.Risk levelThe risk to the UK has been raised to high.
