SCP-3XXX-01 clinging to the rock face after coming in contact with SCP-3XXX.

Item #: SCP-3XXX

Object Class: Keter

Threat Level: Orange

Special Containment Procedures: Samples of SCP-3XXX must be held in a refrigerated BSL-2 storage vault at Biological Sector 2 of Area-10 per biohazard protocol. Acacia, oak, and birch trunks (all variable in sizes) infected with SCP-3XXX will be placed in antibacterial containers in an antibacterial polycarbonate chamber. Decontamination of SCP-3XXX's chamber is required when concluding tests. SCP-3XXX's chamber is restricted to Level-3 personnel and testing is restricted to Level-4 personnel.

Deceased subjects will be secured in lightweight cryo-pods and placed in a BSL-2 cryogenics chamber located at Site-22. All security personnel must be wearing antibacterial Level A hazmat suits when containing. In regards to medical treatment, patients with SCP-3XXX will be introduced to Class B amnestics and undergo checkups once a week. Should there be survivors of SCP-3XXX, they must be quarantined and treated immediately. If SCP-3XXX remains in the carrier, they will be placed in an enhanced solitary confinement cell occluding the carrier from the ground.

Description: SCP-3XXX is an infectious retrovirus amalgamating epidermodysplasia verruciformis (EV) and fibrodysplasia ossificans progressiva (FOP) that infects the organism's skin, the muscular and skeletal system into any tree bark that the being is in contact with, transforming them into "tree beings". No treatment or cure is available yet to reverse the effects of SCP-3XXX. SCP-3XXX transmits when a being is in direct or close contact with a branch or trunk infected with SCP-3XXX. It is also shown that when coming in contact with a carrier of SCP-3XXX, that person also becomes infected. Upon contact, SCP-3XXX lies dormant in the epithelial tissue until it has an opportunity to pierce the immune system, which is about two (2) to four (4) days. SCP-3XXX can occur in these five stages:

  1. In between one (1) to five (3) days, carriers will begin to develop bumped lesions around the legs along with plaques around the neck. Warts may grow inside the epidermis of the carrier and force itself onto the quadriceps and the biceps, fatiguing the carrier.
  2. Within 48 hours after stage one, it will begin to maim upper muscles (especially deltoids and the rotator cuffs), forming phloem around smooth muscles to limit the contractility and slow the moment of the carrier. The outer layers will begin to wrinkle around the arms and upper shoulders, displaying its presence.
  3. SCP-3XXX will then begin to alter the skeletal muscles and bones into xylem, fully restricting the carrier's movement. It can only affect the clavicles and scapula (shoulder bones) and the coxal bones, but it may also affect the ribcage given enough energy.
  4. The carrier's epidermis will start to mutate into the periderm of contacted tree bark and will begin to root itself to any surface the carrier is standing on. The epidermis may also become thick and hardened as the old skin withers and the new skin develops.
  5. At the end of the process, SCP-3XXX will entrap the carrier in a wooden cocoon (of the contacted trunk) and crush their body. There is no assurance of surviving SCP-3XXX, but there have been accounts that some have survived.

SCP-3XXX came to the attention of the Foundation after witnesses had reported a "wooden cocoon" by an abandoned campsite. Agents of the Foundation were sent in to recover the anomaly and freed a teenage boy, M███ L████████ (renamed SCP-3XXX-01 (refer to picture)), from the cocoon. The following details were logged and recorded (see Interview Log 3XXX-1) and SCP-3XXX-01 had been sent to Site-██ for medical treatment.

Addendum 1: Site Director ████ and medical officials have prescribed the use of monoclonal antibody therapy to hinder the effects and possibly stop SCP-3XXX's outbreaks. All patients with SCP-3XXX must undergo therapy and treatment immediately.
