All zombie media has its own version of a zombie and a zombie virus. To create their unique rendering of the zombie, designers usually add numerous symptoms that an infected person experiences before turning.
Each zombie and zombie virus varies in popular media but the basic ground work of a zombie and virus are as follows
- 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.
- Conditioned behavior, motor controls, and instinctive behavioral mechanisms are damaged, and cognitive abilities are severely weakened 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, pushing, pulling, getting back up when knocked to the ground, stalking, moaning, 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.
