2. A credible interval gives an indication of the uncertainty of an estimate from data analysis based on a sample population. 95% credible intervals are calculated so that there is a 95% probability of the true value lying in the interval.

5. No R value was published for the week beginning 27 December 2021 as publications were paused over the festive period. The most recent data point for R is dated 23 March 2022, reflecting the R value as at 8 March.

15. Please note different reference dates for Scotland and other three nations. The ONS aims to provide the estimates of positivity rate that are most timely and representative of each week, and decides the most recent week to report on based on the availability of test results. On most occasions, the reference dates align perfectly, but sometimes this is not feasible. For more information see section "11.

33. Results are taken from questions run on behalf of Scottish Government on the YouGov online omnibus survey. Question 'Coronavirus tests typically take two forms – Rapid 'Lateral Flow or LFD' tests (sometimes called Antigen Tests), which give a test result in 30 minutes and are usually self-administered, or PCR Tests mostly conducted at official Test Sites (but also available as a 'Home Kit) – processed by a laboratory, with results available within 48 hours. In both tests, a swab of nose and/or throat is needed. Which of the following applies to you in relation to testing for Covid-19 in the past week (i.e. since 8 March)?'

34. Question -Thinking about the last lateral flow/antigen test you did in the past week…Which of the following best describes you in relation to that test? (Base: 533 - All who have taken a Lateral Flow/antigen test in the last week)

36. The sample is demographically and geographically representative of adults 18+ across Scotland, with circa 1000 responses each week fieldwork is conducted. YouGov apply weighting to the data to match the population profile to adjust for any over/under representations and to maximise consistency from wave to wave. Parameters used include age, gender, social class, region and level of education.

37. The sample is demographically representative of adults 18+ across Scotland, with circa 3000 responses over two alternating panels. This is modelled to represent the Scottish population.

39. ICU includes combined ICU/HDU figures and both patients with length of stay 28 days or less and with length of stay more than 28 days. Please note that only patients with length of stay 28 days or less in ICU were recorded until 20 January 2021. From 20 January 2021 ICU short and long stay includes both ICU or combined ICU/HDU with length of stay 28 days or less and with length of stay more than 28 days.

40. Before 9 February 2022, patients were only included if they had a recent positive laboratory confirmed PCR test. Hospital and ICU occupancy includes reinfections from 7 March 2022 onwards.

41. The State of the Epidemic report incorporates data up to and including 23 March 2022, so any revisions since then will not be included in this report.

45. Covid-19 related admissions have been identified as the following: A patient's first positive test for Covid-19 up to 14 days prior to admission to hospital, on the day of their admission or during their stay in hospital. If a patient's first positive test is after their date of discharge from hospital, they are not included in the analysis. An admission is defined as a period of stay in a single hospital. If the patient has been transferred to another hospital during treatment, each transfer will create a new admission record.

46. Before 9 January 2022, hospital admissions were only included if the patient had a recent positive laboratory confirmed PCR test. ICU admissions rely on PCR testing only. Hospital admissions data in the chart now includes reinfections and has been updated to include this methodology retrospectively to the start of the pandemic.

47. Greatest revisions are likely to impact the latest two weeks of data; however, longer time periods could be subject to revision.
