Ground Zero: The infection that ended society. How Did it Start?

[mastafigz]

Hey Figz,

What's your counter argument..sorry, counter point, about it not being Airborne? Humans as the vectors makes it transmitted by fluid doesn't it?
Can you please expand on your comment?

Thanks

I mean that, it's possible, that people can be immune to it while it's just an airborne contaminent, but once it's inside a host who isn't immune, it evolves and can be passed along through biting.
