Item #: SCP-XXXX
Object Class: Euclid
Special Containment Procedures: Due to the nature of SCP-XXXX, containment procedures are focused on monitoring medical research related to antibiotics, memory, and pain in humans and animals, and eliminating any outbreaks of SCP-XXXX-B. Should an SCP-XXXX-B outbreak occur, MTF Beta-7 "Maz Hatters" will contain the outbreak and administer amnestics as necessary. Any animals or persons with active SCP-XXXX-B infections should be treated as extremely contagious, quarantined, and brought to the nearest Foundation site.
At least 100 cranial injectors filled with SCP-XXXX-A and a growth medium will be kept in the medical wing of every Foundation site. Four designated medical personnel at each site will be assigned to SCP-XXXX and are to refamiliarize themselves with the SCP-XXXX documentation and administration procedures in 2 person teams every six to 12 hours, or as necessary to maintain constant site awareness of SCP-XXXX. Any knowledge of SCP-XXXX-A lasting longer than 12 hours should immediately be reported to the site head medical director.
Description: SCP-XXXX is the designation given to two biohazardous anomalies. SCP-XXXX-A is a bacteria (Latin name █. █████████) that lives in the brain and nervous system of all animal life, including humans. SCP-XXXX-B is a bacteriophage (Latin name █. ███████████) that specifically targets SCP-XXXX-A. SCP-XXXX-A is assumed to be present in all animal life, as all studies have found SCP-XXXX-A in living creatures, the only exceptions being those infected with SCP-XXXX-B. SCP-XXXX-B outbreaks have been recorded on every major landmass except Antarctica, Madagascar, and Greenland.
SCP-XXXX-A exhibits antimemetic properties, causing it to slowly fade from a person's memory after six to twelve hours. The bacteria survives by consuming memories from the host, primarily the memory of pain and the memory of itself. However, the longer SCP-XXXX-A lives inside of a host, the greater the chance of it mutating to consume other types of memories. This generally causes long term memory loss, though some cases of short term and even immediate memory loss have been reported.
SCP-XXXX-B is a bacteriophage that targets SCP-XXXX-A. SCP-XXXX-A can be spread through almost any means including through inhalation, ingestion, contact with bodily fluids, and contact with mucus membranes. Additionally, SCP-XXXX-B can survive up to 48 hours outside of a host before becoming nonhazardous. Once introduced to a SCP-XXXX-A host, SCP-XXXX-B will quickly spread throughout the nervous system and brain, killing off all instances of SCP-XXXX-A. This process takes between 48-72 hours depending on how SCP-XXXX-B is introduced, with ingestion having the longest incubation period. Additionally, recent research indicates that SCP-XXXX-B may be able to hibernate inside a host, becoming active in response to unknown circumstances.
SCP-XXXX-A was discovered in 2004 after medical researchers at ██████ Pharmaceutical accidentally created SCP-XXXX-B during research into phage therapy. Embedded foundation personnel responded quickly but due to the limited knowledge of SCP-XXXX-A at the time, SCP-XXXX-B infected personnel were unknowingly released from Foundation custody. Since then SCP-XXXX-B outbreaks have been occurring with increasing frequency.
While SCP-XXXX-B doesn't cause harm to living things, the absence of SCP-XXXX-A has extremely detrimental effects. Because SCP-XXXX-A feeds off of the memory of pain, its absence causes subjects (hereafter referred to SCP-XXXX-C) to be able to remember and re-experience pain. In animals this is expressed as an increase in irritability, confused and aggressive behavior, and eventually death from shock. The effects have been better studied in humans, and various tests have been done to fully understand SCP-XXXX-C instances.
After SCP-XXXX-B has run its course, SCP-XXXX-C will begin acquiring memories of any pain they experience. Recalling the memory will cause SCP-XXXX-C to re-experience the pain in full. This generally causes distress in SCP-XXXX-C instances as it becomes more and more difficult for SCP-XXXX-C to avoid recalling painful events. Due to the nature of SCP-XXXX-C, it is assumed that sufficiently large outbreaks of SCP-XXXX-B would cause societal breakdown, mass suicide, and possibly a GK "Dead Greenhouse" scenario, as isolated animal and all plant life would continue to survive. Because of the danger presented by mass outbreaks of SCP-XXXX-B, Foundation medical researchers are currently attempting to create a variant of SCP-XXXX-A that is resistant to SCP-XXXX-B. Research into the possibility of using variants of SCP-XXXX-A to eliminate pain entirely is also ongoing.
TESTING LOG
Test A - 11/04/2005
Subject: D-8135
Procedure: D-8135 is infected with SCP-XXXX-B, infection allowed to run its course. D-8135 then given various physical stimuli including reflex tests and being pricked with a needle in various places, and then asked to recall the experience.
Results: D-8135 confirmed to be able to recall and re-experience pain, SCP-XXXX-C designation created.
Analysis: Further testing to establish full effects of SCP-XXXX-C status needed.
Test B - 20/04/2005
Subject: D-12081, who required amputation of a gangrenous foot.
Procedure: D-12081 is turned into an instance of SCP-XXXX-C, then put under anesthesia and the gangrenous limb surgically removed. After awaking from anesthesia D-12081 was asked to recall the removal of his leg.
Results: D-12081 was unable to recall the pain of the amputation, but over the course of the next 5 days became more and more distressed. D-12081 reported ever-increasing pain in the amputation. After degenerating into moans of pain and then unconsciousness SCP-XXXX-A was reintroduced into D-12081's brain. D-12081 went on to make a full recovery.
Analysis: Anesthesia appears to prevent the memory of pain being retained, but all conscious pains are remembered. The regular pain of an amputation seemed to constantly remind D-12081 of the previous pain, causing it to build exponentially.
