I have a very responsive immune system, and I believe in evolution.
If I catch it I'll ride it out with the rest of the poor people.
If I survive I can get to repopulatin'.
There has been some very good advice given already on this thread, sensible advice.
As far as alternate escape routes, that's an especially salient point. Pick a location to live that has enough seclusion, combined with enough
methods to evacuate.
I live in a mountain valley with two convergent highways nearby, as well as a river and a nearby underground tunnel that leads out to it. The hills
on all sides are impassable to vehicles. Less than a block away there's a watchtower that overlooks the entire town, along with an escape tunnel,
two functional bomb shelters, a warehouse full of heavy earthmoving machinery and fuel, as well as food, water, and tools.
Basically, choose the best location possible for every potential survival situation.
If a flu pandemic does wipe out half the country, the great thing about living in a town like mine is that you wouldn't be able to tell the
difference. Basically nothing would change, except the price of fresh corn and cattle would rise because of demand. No worries.
Being prepared is also about being unafraid of death. If your fear controls you, it's even easier to die, totally self-defeating. One should
recognize fear and take it to heart, fear is a natural reaction and can be very useful, it can help you avoid danger. But if it blinds you in a
crisis you will falter, and stumble at the critical moment.
The best thing to do is be cautious, but unafraid. This is NOT an endorsement of recklessness, lemme be clear about that. Just keep your thinking
cap on during any crisis, if you want to raise the odds of survival for yourself.
