I'm a bit unsure of all this.
First, I'm unsure that plot synopsis is even accurate being that they list Fox as being in the cast which he's clearly not, or at least there's not anywhere else that's reporting it.
Secondly, if it is accurate. The hook of WWZ was the socio-political aspect of the aftermath of the zombies wreaking havoc on the world and how people dealt with it and the fact that zombies were a normal part of life even still.
It's not really a sci-fi action thriller where people are racing against the spread of the virus. (even if by film's end that race fails and opens the door for a sequel(s) that explore the aftermath.)
Plus, what the hell would Lane be doing to stop it? He's a journalist not virologist, unless they go and change that too.
