Combination strategies can be used to reduce the global spread of the influenza virus [12, 13] . Redistribution of limited antiviral drugs can help contain pandemics or reduce the global attack rate (AR) [12] . If global antiviral stockpiles are limited, non-cooperative strategies where countries keep their antiviral stockpiles for their own use can only contain a pandemic influenza virus with Ro less than 1.5; in contrast, if redistribution of 25% of stockpiles from countries that have them to countries that do not, a pandemic with Ro up to 1.9 may be contained, and overall AR reduced by 25% at higher Ro [12] .
