As we see headline after headline about Ebola, and the looming threat of ISIS and instability in the Middle East it is worth considering other (possible more mundane, if no less serious) threats facing the US - namely the flu. A deadly seasonal strand of influenza would wreck far more damage than these other threats - especially considering that the US Dept. of Homeland Security focuses far more on anti-terrorism initiatives than it does on pandemic preparedness. At a certain emotional level, terrorist attacks are far more threatening than the flu. But statistically, the flu is much bigger threat to public health and homeland security.
