Age-prioritized use of antivirals during an influenza pandemic in Italy: excess mortality. Expected excess mortality as obtained by assuming two different age-specific case fatality rates, similar to those estimated for the 1918–19 influenza pandemic in Copenhagen and for the 1969–70 influenza pandemic in Italy respectively, for baseline simulations (green), for antiviral treatment provided to index cases of all age classes (blue) or provided only to specific age classes (cyan, Y = young, A = adults, E = elderly), and for post-exposure prophylactic treatment provided to all age classes (red) or only to specific age classes (orange, Y = young, A = adults, E = elderly).
