Instead of THE GUBBMINT being evil by LOCKING EVERYTHING DOWN in some scary QUARANTINE ZONE or the like, imagine a “got to build up zombie bite immunity” response, or one with pseudoscientific treatments, or pretty much anything so 
can feel like things are back to normal while zombies are just a thing that continues happening.
Add your own ideas if you like. 
Yeah, everything you are suggesting there ; BBC has you covered
Nice! Never heard of this before, I’ll check it out!
I was thinking the same thing. There have actually been a few zombie films/shows that have a similar premise to what joaomarrom was suggesting, at least the part about a cure having been found and former zombies trying to reintegrate back into society. Along with In The Flesh, another one that comes to mind is The Cured which starred and was produced by Elliot Page.
