Coronavirus (COVID-19): modelling the epidemic (issue no. 70)

Footnotes

1 On 16 September 2021, daily data on new cases and tests were not refreshed due to a technical issue affecting the availability of the data.

2 Using data to 20th September.

3 Particular care should be taken when interpreting this estimate as it is based on low numbers of cases, hospitalisations, or deaths and / or dominated by clustered outbreaks. It should not be treated as robust enough to inform policy decisions alone.

4 The cyan bars use Covid-19 test data and purple bars use multiple sources of data. The estimates produced by the Scottish Government are the two on the left. (Yellow uses confirmed cases from PHS and deaths from NRS; green uses wastewater data).The UKHSA consensus range is the right-most (red). Data to 20th September R, incidence and growth rate as of 7^th September.

5 Deaths, Cases and Hospitalisations from PHS COVID-19 daily cases in Scotland dashboard.

6 Vaccination and contact data for the 0-17 age cohort is not presented due to the vast majority of this age group not being offered vaccinations and the SCS excluding contacts between children.

7 All scenarios are based on current vaccine roll-out plans and efficacy assumptions. Data to 20th September.

8 The actual positive tests are adjusted to coincide with the estimated day of infection.

9 Actual data does not include full numbers of CPAP. ICU bed actuals include all ICU patients being treated for Covid-19 including those over 28 days.

10 Three week projections are provided here: Scientific evidence supporting the government response to coronavirus (COVID-19) - GOV.UK (www.gov.uk)

11 The exceptions are Na h-Eileanan Siar, Orkney Islands and Shetland Islands.

12 Values are included in Table 1 in the Technical Annex.

13 Please note fewer models have contributed than in previous weeks to generate the Local Authority forecasts, which should be considered when using this week’s findings.

14 Advancements in detection and interpretation practices allow us to identify when outlying results are anomalous rather than indicators of spikes in Covid-19 levels. Table 2 provides population weighted daily averages for normalised WW Covid-19 levels both with and without the outliers removed. See Technical Annex in Issue 60 of these Research Findings for further details.

15 Coverage as at the week beginning 15th September 2021, when outliers are excluded.
