[@AdobeFlash]exactly vampires still breath and eat, and to move around everything they need blood. The disease gives them enhanced everything else so at the very least we could do something with they are putting so much into those powers that blood producation is massively damages. The disease is trying to weaken a demon and instead is infecting a person bringing their powers up, but with all of that in frail human they get side effects.

so basically, what happened is in some backwater corner of the infernal plane or whatever some fuckwit was like: imma kill my friends, so he made a disease but like dropped it in the human world and boom vampires (its 2am and im on cold medication sorry)
