The demon virus, Wraith virus or The Black Plague is a disease in The Outbreak Story.

Profile
It's not known how the Wraith virus came to be, though SPDF log information traces its origin back to the

Stage 1
The infected victim begins to develop symptoms similar to a bad case of the flu, with extreme fever, fatigue and lack of motivation, after which the victim becomes depressed and frustrated with its surroundings. In this stage, the victim can still be cured, though this is a painful experience to the infected person.

Stage 2
The fatigue, depression and frustration begins to devolve into paranoia and agitation as the flu-like symptoms gradually fade. Sooner or later, the victim will begin to lose its grip and become homicidal. It becomes dangerous to interact with the infected and it is difficult to tie them up, due to the fact they will become more and more aggressive and it is hard to predict how they will act at a time. The person begins to act like a rabid dog in the end. It is still possible to cure the infected person, but it'll become near-to-impossible once the victim is close to the end of Stage 2, in the "rabid" state.

Stage 3
In the final phase, Stage 3, the infection is not reversible anymore and the victim is soon to die from the illness. The infected can be killed, commit suicide in its rabid state or die from the infection, but if the victim dies in Stage 3, the dead body will come back as a soulless, deranged Wraith. It is possible for them to retain a part of their human memories, thought processes and appearance, but almost all Wraiths are only driven by an insatiable hunger to eat flesh, mainly human meat, and the lack of a soul has taken all of their humanity. The newborn Wraith is now going to infect other people with the virus, leading to the infected people going through the same process all over again.
