Smallpox is a terrible disease that ravaged the world for roughly 3,000 years.   Its symptoms include vomiting, nausea, fatigue, backache, headache, and rarely hallucinations.   The incubation period is 12-14 days.       Between this time the victim will begin to develop a red blistering rash.   In the most severe cases the victim will start to have patches of skin that seem charred and black.   This is known as Hemorrhagic Smallpox or the Variola Major virus.   The skin is black because blood is collecting under the skin.   The eyes of the victim will also turn from white to red to black (if they live long enough).   During this strain of the disease the victim has a 96% chance of dying.   In the less severe (but still deadly) strain of the Variola Major virus the victim will develop small zit like sores around the body during the incubation period.   Around day eight, these zits will take two very different courses.  They will either be Hemorrhagic or normal smallpox.   The least deadly form of smallpox is known as the Variola Minor Virus in which the victim only has one percent chance of dying.
