Seems a bit harsh, although once a virus is airborne I think it's fair to say that they'd all be doomed... Gasmask card maybe?
just a mutated strain from one zombie.
besides.. there are 'reach' cards for the hero's now to fight zombies in an adjacent square... plus it's actually less effective than the 'bitten' card as it only dupes it, plus the zombie actually has to hit.. and there is no wound either..
