With the way folks jet all over the world,all it's gonna take is for a mutated strain to wind up in somebody hacking on a plane to a central hub somewhere.It'll spread like wildfire.
I'm not preparing for bird flu alone:I've always tried to be ready for ANYTHING:natural disasters,civil unrest,unemployment,etc
We've tried to live as self -sufficiently as possible.
Raise/hunt most of our own meat,canning,etc
Have PLANTY of nitrile gloves,N95 masks,seasoned wood,food,water,meds,etc
I've always had at least a month worth of everything on hand,but have stepped it up to two.
