Origin: The original source of the infection is unknown; Though theories abound. Some in Great Britain believe it is a mutated strain of the Mad Cow Disease. Meanwhile there are areas in the United States that believe it was a government weapon that they lost control of. There are of course theories of aliens, ghosts and religious punishments. A number of tribes have legends generations old that speak of the walking dead.

What is known is that the infection had reached epidemic status long before the outbreak became public. This is evident in the massive amount of attacks that happened in a short period of time globally. It is hard to believe that in an age offering easy access to most information that such a thing could happen. However in a retrospective consideration the rational explanations assigned to the initial attacks were enough to disguise the growing threat.

Symptoms: While the symptoms are always the same there are some differences in the amount of time taken before they show. There are theories on how to slow the spread of the infection through the body. Unfortunately, none of these theories have proven consistent. The following times are an estimated average; Again however these times are not 100% accurate.

Spoiler: Timetable after infection. 


Transmission: The infection is spread through bodily fluids. Saliva and blood being the usual transferal method. The smallest exposure results in infection, the source appears to spread quickly. The infection can not be spread through the ingestion of infected material (given the ingestor has no open sores in their mouth.) However the infected material is highly toxic.

Interspecies infection has remained unwitnessed. It is believed the same aspect of the infection that turns toxic when ingested prevents the infection from taking hold in animal life. Additionally most animals seem capable of detection the infected, and attempt to avoid them. Long term effects remain unknown; Especially on life forms that survive on carrion.

Stages: The infection in truth has three stages. Though typically two are recognized as components of the infection; As the initial stage shares symptoms similar to the flu. The stages related to the infection will be discussed below.

Spoiler: Stage 1 


Spoiler: Stage 2
