1. Covasim is a stochastic agent-based simulator for performing Covid-19 analyses. This has been modified using Scottish demographic data and contact patterns from the Scottish Contact Survey. Covasim: An agent-based model of COVID-19 dynamics and interventions (plos.org)
2. 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.
3. The cyan bars use Covid-19 test data and purple bars use multiple sources of data. The estimates produce by the Scottish Government are the two on the left. (Green uses wastewater derived data; yellow uses the agent-based model). The UKHSA consensus range is the right-most (red). Data to 11th April 2022. R and growth rate as of 29th March 2022.

10. "DZ Range" indicates the range of values of the risk factor that are observed across datazones (DZ), showing the lower 5th percentile and upper 95th percentile of the range. Changes reflect the relative change in cases compared to the median, when each risk factor is at the two extremes of the DZ range. Data was taken from eDRIS on 11th April 2022, and analysis reflects data from 26th March to 9th April 2022. Percent second vaccine dose uptake defined as the proportion of individual vaccinations recorded per DZ who had received a first dose (similar definition for booster doses). Most important/significant risk factors are in bold.
11. For this graph, a wastewater Covid-19 average using the last 7 days of data is computed at every sampling date. Prevalence estimates and 95% confidence intervals from the ONS Coronavirus Infection Survey is overlaid, with a scale chosen to approximately match recent trends in WW Covid‑19.
12. 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 SARS-CoV-2 RNA levels with the outliers removed. See Technical Annex in Issue 60 of these Research Findings for further details.
