Item #: SCP-2546
Object Class: Keter
Special Containment Procedures: SCP-2546-1 through -600 are stored in a standard BSL-3 facility within Site-234. All work with these samples is carried out in appropriate BSL-3 personal protective equipment and conditions. Personnel assigned to work with SCP-2546 samples should have a minimum of 5 years experience working with retroviruses, of both anomalous and non-anomalous nature. Requests for creation of additional aliquots are subject to level 4 review.
In the event of accidental exposure, affected individuals are to be placed on anti-retrovirals, and monitored for changes in: cell surface receptors, genetic markers, bloodstream hormone levels, and behavioral patterns. Should affected individuals begin displaying any physical or mental alterations consistent with SCP-2546 infection, they are to be placed under level 2 humanoid quarantine. Once an infected individual's viral load has fallen below infection thresholds, they are to receive minor plastic surgery, and comprehensive class C amnestic treatment.
In the event of an outbreak, MTF-Chi-7 "Plague Tamers" are to be deployed, and Protocol Anthro-Lenti 5 enacted. Due to the slow-acting nature of SCP-2546, infections may not be detectable or become apparent until several weeks following exposure. Containment of infection following exposure1 is of the highest priority. Individuals exposed to SCP-2546 strains corresponding to high ranking Foundation Employees should be monitored closely by medical personnel. When these individuals fall below the infectious threshold, they are to be briefed on their current situation, and offered facial reconstruction and employment in a post of their choosing.
Foundation reconnaissance personnel identifying any individual consistent with the description of PoI-2546-A are to alert MTF's Chi-7 and Tau-9 (Bookworms). Attempts to capture and/or neutralize PoI-2546-A are to observe utmost caution.
Description: SCP-2546 is the collective designation for 600 identified, and an unknown number of unidentified, anomalous retroviruses. All SCP-2546 instances are retroviruses of the genus lentiviridae, and are structurally similar to other retroviruses within the group, especially HIV. All SCP-2546 have a capsid 720 nm in diameter2 and are capable of binding to the surfaces of all cells within the human body, regardless of cell surface profile. SCP-2546 primarily spreads, in the wild, through sexual/intimate contact, and/or accidental bloodstream exposure, making person to person spread primarily limited to sexual partners. Unlike other viruses, both anomalous and non-anomalous, SCP-2546's primary function is not only to propagate itself, but also to alter its host. SCP-2546's genome is thus quite large, and codes for an additional 34 proteins which perform its primary anomalous effect.
SCP-2546's anomalous effects begin upon infection of a single cell within the host's body. Upon entry, the virus makes its way to the center of the cell, where it will begin shedding its protein shell. SCP-2546 will then proceed to dismantle the existing chromosomes, utilizing 34 proteins to unwind, destroy, and replace the host's chromosome utilizing the denatured particles as building blocks. It is unclear how exactly these proteins are able to synthesize and organize these new chromosomes without a template; however, thorough analysis has pinpointed several repeated sequences/structures which are unique to each virus and may be related to this process.
The average time between initial infection and chromosome replacement is estimated to be between 3-5 days.3 Altered cells produce virus continuously for a period of 3 months, at the end of which they become impermeable to further infection with the same virus. SCP-2546 primarily spreads through the body via the immune system, where it takes advantage of the close proximity necessary for immune cells to fulfill their functions, and by proxy prevents the host's immune cells from negatively reacting with cells possessing replaced chromosomes.
As a direct result of SCP-2546's chromosome replacement, infected individuals are subject to a long, painful, and severely distressing transformation wherein on the genetic, physical, and mental levels they undergo complete transmogrification into the corresponding person.4 This transformation's length varies based on the viral load that the individual was originally exposed to, ranging anywhere from 1-10 years. Symptoms of infection vary from individual to individual, and many may not be noticeable immediately due to the lengthy reproductive cycle of each virus; however, some of the more notable symptoms are detailed below:
- Alterations to skeletal structure including loss/gain of height.
- Increase/decrease in muscle mass and fat content.
- Muscle aches/fatigue, sharp and/or chronic pain in the bones.
- Progression/Reduction of ageing.5
- Physical dissociation/loss of sense of self.
- Changes in skin pigmentation.
- Behavioral alterations/personality shifts/changes in preferences.
- Slow loss of personal memories, and gradual gain of the corresponding person's memories.6
- Changes to internal organs affecting their function.
- Hormone level fluctuations.
- Reproductive organ alterations.
- Confusion, disorientation, inability to recognize themselves and/or significant cognitive dissonance.
- In rare cases, death due to internal trauma.
SCP-2546 was first discovered by Foundation personnel implanted amongst ████ University local medical center. Kyle ███████, officially dubbed "patient zero", came to the center seeking medical treatment for a variety of symptoms now known to be associated with SCP-2546.
