I think the best course of action is to do absolutely nothing. There are literally hundreds of stories every year that predict hundreds if not thousands of deaths due to some unknown/unstoppable disease, etc. I remember several years ago that there was a headline in most of the 'redtop' newspapers which said something to the effect of, �Deadly Flesh-Eating Bug Attacks Britain!�. This apocalyptic headline was accompanied by a skull-and-cross-bones emblazoned on the map of the British Isles. If I remember correctly, about four or five people were affected...
The fact is that scare stories sell newspapers and sell advertising space. It's in the news corporation's interest to tell everyone that they're in immediate danger. Governments also profit from using this tactic too � terrorism anyone?
I'm not saying that another Spanish flu outbreak will not happen again (it almost certainly will and because of the increased population density, it is likely to be even more devastating than the previous one), but what I am saying is that there's nothing you or I or anyone else can do about it so don't let a hypothetical situation freak you out.
