Fig. 1.

Power-law growth model fits to reported deaths for Belgium, China, Denmark and Germany, shown with $\pm$95% confidence interval (CI) bands (shown in green). The data points (filled circles) are generated from a 5 day moving average of number of daily deaths reported by the World Health Organisation (2021), for the first wave of infections in 2020. In each case, the date of the first reported death (day 1) is indicated at $t=0$ on the time axis.
