It has come to my attention that after a transition to zombie state, the zombie's penile organ will swell to a large diameter, thus this is a tool the zombie will use to lure uninfected women. Studies have shown that the virus IS transmitted in a sexual manner, and the emitting of some kind of pheromone makes it hard to resist, so training should be implemented on how to resist such a lure. The lack of sexual satisfaction, due to the male population being occupied with the extermination, will cause females to be easley wooed by the well hung infected male population. In order to keep a large infection free pool of breeding females, a holding facility should be planed, or other means of preventing visual contact with the organ in question should be arranged. If interaction is enviable a good supply of Lysol should be kept on hand.
