SCP-610 Overview and Containment

Sep 9, 2025

Overview

This summary outlines the properties, containment, and exploration of SCP-610, a horrifying, highly contagious disease in the SCP universe. The disease causes extreme bodily deformation, aggressive behavior, and rapid environmental spread, leading to several fatal encounters by Foundation personnel.

SCP-610 Overview and Containment

  • SCP-610 is a Keter-class anomaly, considered impossible to contain.
  • The infection is currently isolated in southern Siberia, Russia, mainly around Lake Baikal.
  • Transmission occurs primarily through physical contact, not water or air.
  • Standard response is immediate termination of infected individuals using small arms and incendiary weapons from a distance.

Initial Outbreak and Discovery

  • The Russian government notified the Foundation after people, police, and an agent disappeared in the affected region.
  • Early symptoms include rashes and itching; the disease quickly covers the body with scar tissue.
  • Infected individuals experience death and rapid bodily mutation, often developing new limbs or splitting body parts.

Transmission and Infection Behavior

  • Some infected seek out and attack humans, spreading the infection.
  • Others root themselves and create hospitable environments for further disease growth and spread.
  • Infection can rapidly terraform environments, notably increasing local temperatures.

Exploration Logs and Encounters

  • Remote drones (e.g., "Herbie") and human teams conducted multiple explorations of infected villages and underground tunnels.
  • Notable observations: infected individuals interacting, material consumption rituals, aggressive assaults on non-infected, and signs of organized behavior.
  • D-Class personnel missions documented rapid fatal infection, destruction of infected masses, and environmental responses such as explosions and seismic events.

Major Incidents and Discoveries

  • Destruction of a major infected mass caused simultaneous events at multiple sites, killing surface-level infections but triggering underground activity.
  • Exploration of tunnels revealed deep infection networks, mutated creatures, and an apparent village constructed entirely of SCP-610 material.
  • Underground expeditions faced ambushes from 610 entities, with only incendiary weapons proving effective.

Underground Village and Final Assault

  • A hidden village featured a church with captive, partially infected humans and ritualistic feeding on living tissue.
  • Team members were ambushed by mutated entities, suffering heavy casualties and equipment loss.
  • No expeditions have been attempted since; all field teams were lost or presumed dead.

SCP-610 and Broader Context

  • SCP-610 is theorized to be linked to the fictional Sarkic cults and the "Red Death," tying into larger SCP lore.
  • The infection is notable for its complexity, horror, and environmental impact compared to real-world diseases.
