Data and confirmed daily cases charts in panels 3-4 sourced from https://coronavirus.data.gov.uk/. According to this source “COVID-19 cases are identified by taking specimens from people and sending these specimens to laboratories around the UK to be tested for COVID-19 antigens. If the test is positive, this is a referred to as a lab-confirmed case. If a person has had more than one positive test they are only counted as one case. Data can be presented by specimen date (the date when the sample was taken from the person being tested) or by reporting date (the date the case was first included in the published totals). The availability of each of these time series varies by area.” They also note that “on 2 July, case data from pillars 1 and 2 of the testing programme were combined and de-duplicated, resulting in a step decrease in the cumulative number of cases reported.” Charts in the panels reused under the Open Government Licence v3.0.
