Figure 1.

All-cause mortality estimated using 10-year (2010–2019) and 5-year (2015–2019) weekly average mortality estimates. Average all-cause mortality in the previous 10 years (mortality_10: 2010–2019) and previous 5 years (mortality_5: 2015–2019), further split into the following timeframes: pre-outbreak (weeks 1–12); outbreak (weeks 13–27); post-outbreak (weeks 28–42). The point-estimates using the 10-year baseline are somewhat higher (although not statistically significant) than those using the 5-year baseline, but the variability is much less when the 10-year average is used.
