Speculation over the cause of 'zombie-ism' is rife here at the C.Z.R.G. We can only assume what the causes are due to lack of information and specimen research. To this day, the governments of the world seems to have done their job protecting us from a zombie outbreak or the incidents we have seen are just a part of a controlled experiment. Would there even be an outbreak caused by a virus? Is it even a virus? We have little evidence to suggest such a thing, however, it seems to be the most logical assumption.
What kind of virus could it be? What would cause a human to become so violent and invincible at the same time? Evidence suggests that zombies have a hunger for human flesh and can only be eliminated by destroying the brain. How can this be? This defies the science that the 'mainstream' world knows.
What about some sort of mutant form of rabies? Rabies has been reported to infect human beings and almost always is fatal without vaccination. Rabies is usually but not always passed around when a bite is inflicted. In many cases the affected animal is exceptionally aggressive, may attack without provocation, and exhibits otherwise uncharacteristic behavior.
After the virus enters the body, it attacks nerve endings and continues to attack the nervous system all the way up to the brain. Once it reaches the brain, encephalitis takes place. Once symptoms become obvious it takes about 10 days for the human to succumb to the virus.
Now we can safely assume that a zombie is not simply a rabid human. Where does the hunger for flesh come in and the invincibility? Enter the mutant strain of rabies.
This would probably consist of a parasitic form of the rabies, in that, the rabies would travel to the brain and the parasitic properties would begin to take place. The strain would take control of the r-complex or 'reptilian brain'.
The 'reptilian brain', evolutionarily speaking, is the part of the human brain that is responsible for the most basic and primitive in human skill, instinct, and survival. Rage, fight-or-flight responses, and xenophobia are a few functions contributed to by the r-complex. The mutant strain of rabies latches on to this part of the brain and begins to break down the rest of the brain. This becomes the main 'housing' of the parasite. This may also explain the sudden death of a zombie once it's brain has been destroyed. You see, its not the brain that you are destroying, its this parasitic hive that has formed on the r-complex. From here the parasitic virus takes control of mostly all of the bodily functions and feeds on whatever the parasite needs to survive. (Read this interesting article, In Our Messy, Reptilian Brains).
This is probably blood and other bodily fluids. This could mean that when the fluids of the host body have been consumed, the parasite's hunger for more leads to the murderous, cannibalistic nature we have seen in zombies. Its not necessarily the human flesh that they are after, its the bodily fluids.
Now, the question remains. Why is it then that a zombie is only stoppable when the brain is destroyed? This defies my logic and only time will tell.
