What Is A Zombie?
According to Merriam-webster the definition of a zombie is as follows: ZOM-BIE: n. also ZOM-BIES pl. 1. a will-less and speechless human in the West Indies capable only of automatic movement who is held to have died and been supernaturally reanimated. 2.the supernatural power that according to voodoo belief may enter into and reanimate a dead body.
Human beings can turn into zombie once the virus enters the blood stream. This usually happens through either a bite or scratch wound from a zombie. It's important to note that the virus shuts down most vital organs thus killing the infected, only to be reanimated within minutes. A body will not reanimate if not infected before dying.
Depending on the person and the location of the entry point, an infected person may have hours before reanimating. Here is a timetable of symptoms according to Max Brooks: Zombie Survival Guide
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 20:Heart stoppage. Zero brain activity.
Class 1This is a low-level outbreak, usually in a rural area. The number of zombies in this class of outbreak ranges between one and twenty. Total human casualties (including those infected) range from one to fifty. The total duration, from the first case to the last (known), will range between twenty-four hours and fourteen days. The infested area will be small, no larger than a twenty mile radius.
Class 2Urban or densely populated rural areas are included in this level of outbreak. Total zombies will range between twenty and one hundred.
Total human casualties may reach as high as several hundred. The duration of a Class 2 attack may last no longer than a Class 1 outbreak. In some cases, the larger number of zombies will spark a more immediate response. A rural, sparsely populated outbreak may extend to a hundred-mile radius, while an urban outbreak may encompass only several blocks. Suppression will almost certainly be organized. Bands of civilians will be replaced by local, state, even federal law enforcement. Look for an additional, if low-level, military response, the National Guard in the United States or its equivalent abroad. Most often, so as to ease panic, these units will take a more noncombatant role, providing medical assistance, crowd control, and logistical support.
Class 3A true crisis. Class 3 outbreaks, more than any other, demonstrate the clear threat posed by the living dead. Zombies will number in the thousands, encompassing an area of several hundred miles.
The duration of the attack and a possible lengthy mop-up process could last as long as several months. There will be no chance for a press blackout or cover up. Even without media attention, the sheer magnitude of the attack will leave too many eyewitnesses. This is a full-blown battle, with law enforcement replaced by units of the regular military. A state of emergency will be declared for the infested zone, as well as the neighboring areas.
