Estimates of excess mortality rates attributable to pandemic influenza based on all‐cause mortality rates across 25 provinces of Chile. Excess mortality estimates for each wave were computed using a seasonal regression model applied to monthly mortality and presented as rates per 10 000 as described in the text. Provinces are sorted by latitude from north to south Chile
