Hour 1: Pain and discoloration (brown-purple) of the infected area. Immediate clotting of the wound (provided the infection came from a wound).
Hour 5: Fever (99–103 degrees F), chills, slight dementia, vomiting, acute pain in the joints.
Hour 8: Numbing of extremities and infected area, increased fever (103–106 degrees F), increased dementia, loss of muscular coordination.
Hour 11: Paralysis in the lower body, overall numbness, slowed heart rate.
Hour 16: Coma.
Hour 20: Heart stoppage. Zero brain activity.
Hour 23: Reanimation.
3. Transference
Solanum is 100 percent communicable and 100 percent fatal. Fortunately for the human race, the virus is neither waterborne nor airborne. Humans have never been known to contract the virus from elements in nature. Infection can occur only through direct fluidic contact. A zombie bite, although by far the most recognizable means of transference, is by no means the only one. Humans have been infected by brushing their open wounds against those of a zombie or by being splattered by its remains after an explosion. Ingestion of infected flesh (provided the person has no open mouth sores), however, results in permanent death rather than infection. Infected flesh has proven to be highly toxic.
No information—historical, experimental, or otherwise—has surfaced regarding the results of sexual relations with an undead specimen, but as previously noted, the nature of Solanum suggests a high danger of infection. Warning against such an act would be useless, as the only people deranged enough to try would be unconcerned for their own safety. Many have argued that, given the congealed nature of undead bodily fluids, the chances of infection from a non-bite contact should be low. However, it must be remembered that even one organism is enough to begin the cycle.
4. Cross-species Infection
Solanum is fatal to all living creatures, regardless of size, species, or ecosystem. Reanimation, however, takes place only in humans. Studies have shown that Solanum infecting a non-human brain will die within hours of the death of its host, making the carcass safe to handle. Infected animals expire before the virus can replicate throughout their bodies. Infection from insect bites such as from mosquitoes can also be discounted. Experiments have proven that all parasitic insects can sense and will reject an infected host 100 percent of the time.
5. Treatment
Once a human is infected, little can be done to save him or her. Because Solanum is a virus and not a bacteria, antibiotics have no effect. Immunization, the only way to combat a virus, is equally useless, as even the most minute dosage will lead to a full-blown infection. Genetic research is under way. Goals range from stronger human antibodies to resistant cell structure to a counter-virus designed to identify and destroy Solanum. This and other, more radical treatments are still in the earliest stages, with no foreseeable success in the near future. Battlefield experiences have led to the immediate severing of the infected limb (provided this is the location of the bite), but such treatments are dubious at best, with less than a 10 percent success rate. Chances are, the infected human was doomed from the moment the virus entered his or her system. Should the infected human choose suicide, he should remember that the brain must be eliminated first. Cases have been recorded in which recently infected subjects, deceased by means other than the virus, will nonetheless reanimate. Such cases usually occur when the subject expires after the fifth hour of infection. Regardless, any person killed after being bitten or otherwise infected by the undead should be immediately disposed of. (See “Disposal.”)
6. Reanimating The Already Deceased
It has been suggested that fresh human corpses could reanimate if Solanum were introduced after their demise. This is a fallacy. Zombies ignore necrotic flesh and therefore could not transfer the virus. Experiments conducted during and after World War II (see “Recorded Attacks”) have proven that injecting Solanum into a cadaver would be futile because a stagnant bloodstream could not transport the virus to the brain. Injection directly into a dead brain would be equally useless, as the expired cells could not respond to the virus. Solanum doesnot create life—it alters it.
Zombie Attributes
1. Physical Abilities
Too often, the undead have been said to possess superhuman powers: unusual strength, lightning speed, telepathy, etc. Stories range from zombies flying through the air to their scaling vertical surfaces like spiders. While these traits might make for fascinating drama, the individual ghoul is far from a magical, omnipotent demon. Never forget that the body of the undead is, for all practical purposes, human. What changes do occur are in the way this new, reanimated body is used by the now-infected brain. There is no way a zombie could fly unless the human it used to be could fly. The same goes for projecting force fields, teleportation, moving through solid objects, transforming into a wolf, breathing fire, or a variety of other mystical talents attributed to the walking dead. Imagine the human body as a tool kit. The somnambulist brain has those tools, andonly those tools, at its disposal. It cannot create new ones out of thin air. But it can, as you will see, use these tools in unconventional combinations, or push their durability beyond normal human limits.
A. Sight
The eyes of a zombie are no different than those of a normal human. While still capable (given their rate of decomposition) of transmitting visual signals to the brain, how the brain interprets these signals is another matter. Studies are inconclusive regarding the undead’s visual abilities. They can spot prey at distances comparable to a human, but whether they can distinguish a human from one of their own is still up for debate. One theory suggests that the movements made by humans, which are quicker and smoother than those of the undead, is what causes them to stand out to the zombie eye. Experiments have been done in which humans have attempted to confuse approaching ghouls by mimicking their motions and adopting a shambling, awkward limp. To date, none of these attempts have succeeded. It has been suggested that zombies possess night vision, a fact that explains their skill at nocturnal hunting. This theory has been debunked by the fact that all zombies are expert night feeders, even those without eyes.
B. Sound
There is no question that zombies have excellent hearing. Not only can they detect sound—they can determine its direction. The basic range appears to be the same as that for humans. Experiments with extreme high and low frequencies have yielded negative results. Tests have also shown that zombies are attracted by any sounds, not just those made by living creatures. It has been recorded that ghouls will notice sounds ignored by living humans. The most likely, if unproven, explanation is that zombies depend on all their senses equally. Humans are sight-oriented from birth, depending on other senses only if the primary one is lost. Perhaps this is not a handicap shared by the walking dead. If so, it would explain their ability to hunt, fight, and feed in total darkness.
C. Smell
Unlike with sound, the undead have a more acute sense of smell. In both combat situations and laboratory tests, they have been able to distinguish the smell of living prey above all others. In many cases, and given ideal wind conditions, zombies have been known to smell fresh corpses from a distance of more than a mile. Again, this does not mean that ghouls have a greater sense of smell than humans, simply that they rely on it more. It is not known exactly what particular secretion signals the presence of prey: sweat, pheromones, blood, etc. In the past, people seeking to move undetected through infested areas have attempted to “mask” their human scent with perfumes, deodorants, or other strong-smelling chemicals. None were successful. Experiments are now under way to synthesize the smells of living creatures as a decoy or even repellent to the walking dead. A successful product is still years away.
