Most who contract XV-1013 will die. Their bodies undergo an extreme physiological transformation. The virus travels through the circulatory system until it reaches the brain where it begins the transformation in which it attempts to take over the host.
The virus symptoms roughly occur in the following order from the time of the infection:
- 1-2 Hours – Pain and discoloration in the immediate area of infection, slight fever
- 3-5 Hours – Fever rises to nearly fatal levels, vomiting, acute pain
- 6-9 Hours – Numbness radiating from infection sight, dementia, tremors, accelerated heart rate
- 10-12 Hours – Extreme pain, total dementia, hyper-accelerated heart rate
- 12-16 Hours – Paralysis, all vital signs decrease
- 16-20 Hours – Coma
- 20-48 Hours – Stage Two, or recovery
Once a victim enters Stage Two, or XV-1013 Bravo, they become ambulatory and should be considered extremely dangerous. They will have lost all capacity for any thought other than the seemingly unquenchable need to feed. The Infected will then attack any human that it can and will consume their flesh.
It is believed that XV-1013 transforms the body but in the process, destroys its natural processes. The virus needs to consume living tissue in order to survive, and this is why the stage two infected appear to be cannibalistic. Once a victim is in Stage two their blood will have gelled and is considered to be a low risk contaminant. However the saliva, thicker than in a non-infected persons, appears to be the medium of transmission, but only for a limited amount of time before the virus dies. There is no recovery from a stage two infection, the only outcome is death.
XV-1013 does have weakness. Oxygen is extremely toxic to VX-1013 Bravo. If oxygen (air) is introduced into the brain cavity the virus will die rapidly, and all ambulation of the victim stops, in essence the infected is dead.
Most everyone exposed to XV-1013 will display the above symptoms roughly along the given timeline. However, between hours 20 – 48 the victim will either progress to stage two, or they will begin recovery. A small percentage (unable to determine the exact percentage at this time) of those infected have been able to make full recoveries within two weeks of the infection. During the recovery period they are extremely weak and require nearly constant fluids and rest. It is believed, but not confirmed that those that recover are thereafter immune to XV-1013 and XV-1013 Bravo. Also unconfirmed at this time are reports that some people are naturally immune to XV-1013 and XV-1013 Bravo.
