: There was a virus down there, that's the one I'm thinking of, but Blake never

From This Side Toward Enemy:
There's a virus down here which kills Pfhor
in a matter of hours; our S'pht say it was
bio-engineered by their ancestors during
the war against the Pfhor a thousand years
ago. Whatever; it's saving our butts.
That's the last we hear of the virus in the entire trilogy. My best guess is that they had no way to manufacture the virus and because it was so fast in killing Pfhor, it wasn't very effective as an infecting agent. Remember, a really successful virus kills its victims slowly if at all. The longer a victim remains infectious but asymptomatic, the more opportunity the victim will have to spread it to others.
