SCP - 008: Zombie Plague

Name: SCP-008 or Zombie Plague Virus Features: Signs of infection include: Flu-like symptoms with high fever, plus severe dementia in later stages. Coma onset approximately 20 hours after first symptoms appear and 12 hours after noticeable dementia. Coma onset will be considered onset of death. A period of sporadic cellular necrosis occurs which comes to resemble gangrene. Surviving tissue assumes its original function and is highly resilient. Red blood cells greatly increase oxygen storage capacity, resulting in slower blood flow and increased muscle endurance and strength. Nervous and muscular systems are unaffected by total organ failure for several hours. Metabolism may decrease to extremely low levels, allowing subject to survive for over 10 years without nutrition. High blood viscosity results in negligible blood flow from gunshot, puncture, and slashing injuries. Personality of those infected: Conditioned behavior, motor controls, and instinctive behavioral mechanisms are damaged, and cognitive abilities are severely retarded and erratic. Animals experience excessive brain necrosis and are inactive. Subject can adapt to its damaged nervous systems but is limited to basic physical activities, including standing up, balancing on two legs, walking, biting, grabbing, and crawling. Subject will energetically move towards sights, sounds, and smells it associates with living humans. Subject will attempt to ingest living humans if physical contact is made. Neutralizing fully-infected subjects requires significant cranial trauma. Backstory: The virus was accidentally released while within a host. The host made it to Shi no Miyako, but not before attacking and infecting other train passengers. Before long, the whole train got infected and everyone was unleashed on the city.
