Daily Data


These daily data sources help to indicate the current picture.  All data sources have biases and limitations. The earliest daily data sources available closest to the time of occurrence are government published figures on laboratory confirmed cases and deaths in hospital.

Numbers of lab-confirmed positive cases presented in this update include those identified by testing in all settings (pillars 1 and 2):

  • Pillar 1: swab testing for those with a clinical need, and health and care workers by Public Health England (PHE) labs or NHS hospitals. 
  • Pillar 2: swab testing for the wider population, as set out in government guidance, run in conjunction with Randox and Deloittes.  

The data relates to individuals who tested positive from 31st March 2020 onwards.

These data are from Public Health England and are published daily at and shows the total number of laboratory-confirmed cases of COVID-19 amongst Bolton residents during the pandemic. Published data for previous days may change. Data on new cases are received by PHE from the labs daily, but will include results for tests undertaken in the previous days. Data for the last 5 days should be considered incomplete; they may be revised.

As the testing regime widens, increasing numbers of cases will be detected. Increases may be due to a true rise in the number of new cases and/or wider availability of testing. Prior to 10th April 2020, hospital patients have been the priority for testing, so data for this period reflects people who required hospital care. From 10th April 2020, figures for positive tests will also include positive test results for key workers. Further information around testing can be found at

Hospital Deaths

These data are the total number of deaths of patients who had tested positive for COVID-19 at Royal Bolton Hospital during the pandemic to date. The data are reported daily by Bolton NHS Foundation Trust to NHS England and published at

The deaths are recorded against the date of death – which means previous data may get updated as records get updated. For this reason, we advise caution about comparison of numbers day to day. These data are incomplete and have not yet been subject to the verification, checking and coding processes undertaken by the Office for National Statistics.

They will include deaths to residents of other local authorities occurring in Royal Bolton Hospital, and will exclude deaths to residents of Bolton where the death occurs in another hospital. These figures do not include deaths outside hospital, such as those in care homes. The horizonal axes in the chart covers the time period from 2nd March 2020 to 30thJune 2020. This period has been chosen to help display the data clearly.
