Fig. 2: The time series of weekly COVID-19 cases and growth rates, population mobility, symptom searches, and the COVID-19 vaccination coverage.

The five panels present various input data included in the analysis aggregated across the UK, including weekly COVID-19 cases (a), log scaled weekly COVID-19 growth rates (b), Google searches of the eight base symptoms (c), Google mobility metrics (d) and the COVID-19 vaccination coverage (e). Due to the missingness of the baseline searches before the pandemic, we were unable to estimate the changes in Google symptom searches of the eight base symptoms in week 1/31.
