Contagion Lyrics

Lyric discussion by Orichalcon 

Cover art for Contagion lyrics by Fear Factory

I think it's more of a metaphor. It sounds more like the writer is talking about the need for humanity to fight and wage war, and how that need/desire for violence is like a contagion, or a terminal illness.

"We must find the cure before we die" ie: our violent nature will eventually cause us all to kill each other.
