  Ebola - Wikipedia, the free encyclopedia
Ebola is believed to be a zoonotic virus, although despite considerable effort by the World Health Organization no animal reservoir capable of sustaining the virus between outbreaks has been identified.
Ebola goes on to cause diarrhea, dark or bloody stools, vomiting blood, red eyes from swollen blood vessels, red spots on the skin from subcutaneous bleeding, maculopapular rash, purpura, and bleeding internally and externally from any orifice, including from the nose, mouth, rectum, genitals or needle puncture sites.

 Ebola Hemorrhagic Fever - MSN Encarta
Ebola hemorrhagic fever is a zoonosis—that is, a disease that animals spread to humans.
Each outbreak of Ebola hemorrhagic fever has been traced to what is known as an index case, a person who became infected by coming into contact with an animal involved in the life cycle of the Ebola virus.
Ebola hemorrhagic fever is diagnosed using a laboratory technique called enzyme-linked immunosorbant assay (ELISA) that searches blood samples for specific antigens (viral proteins) or antibodies made by the infected patient.

 Note on another hemorrhagic fever
Ebola will be a tough disease because it is probably at least a "500 gram disease" but with a disease where anyone survives, the survival rate should be markedly increased with the use of massive doses of intravenous sodium ascorbate.
With the hemorrhagic fevers or any severe infectious disease, the patient's vitamin C is burned up by free radicals so rapidly that they get "acute induced scurvy." One of the symptoms of scurvy is bleeding of course.
The Ebola is probably a 300 to 500 gram disease so it rapidly causes a severe acute induced scurvy which causes bleeding throughout the body, malaise, coma, death, etc. There has recently been discovered a toxin produced by the Ebola virus which damages the blood vessels and causes the bleeding.

 eMedicine - Ebola Virus : Article by John W King, MD
Although agents of the viral hemorrhagic fever syndrome constitute a geographically diverse group of viruses, to date, all are RNA viruses, all are considered zoonoses, all damage the microvasculature resulting in increased vascular permeability, and all are members of 1 of 4 families: Arenaviridae, Bunyaviridae, Flaviviridae, and Filoviridae.
Ebola and Marburg viruses are responsible for well-documented outbreaks of severe human hemorrhagic fever with resultant case mortality rates ranging from 23% for Marburg virus (Marburg, Germany; 1967) to 88% for Ebola virus (Yambuku, Democratic Republic of the Congo [DRC]; formerly Zaire; 1976).
Ebola hemorrhagic fever should be considered in patients with recent travel to areas where Ebola has been reported or in patients with exposure to known cases and who exhibit signs and symptoms consistent with Ebola.

 ISU Veterinarian - "Ebola Hemorrhagic Fever"
Simian hemorrhagic fever virus and a new strain of Ebola virus were isolated concurrently from a group of cynomolgus monkeys housed in a quarantine facility in Reston, VA. The Ebola virus spread slowly within quarantine rooms, with death occurring within 2 to 7 days following the onset of clinical signs.
The infectivity of Ebola virus is stable at room temperature (20°C) but is largely destroyed in 30 minutes at 60°C. The virus can also be inactivated by ultraviolet and gamma radiation, lipid solvents, B-propiolactone, and commercial hypochlorite and phenolic disinfectants.
The solutions to accomplishing these goals are educating the public in regard to the signs of Ebola hemorrhagic fever and developing a practical and effective method of identifying infected persons and carriers of the virus.
