Ebola is a member of the filovirus family (Marburg virus). Filovirus can cause severe hemorrhagic fever, which symptoms are, fever, vomiting, prostration, petechial hemorrhages, hypotension, and muscle pain. There are only two members of this virus family (Ebola & Marburg virus). Ebola have five strains with one Ebola-Reston not causing severe disease in humans.

The Filovirus was discovered in 1967 in Germany and Yugoslavia. Researchers were analyzing tissue of a green monkey, which had the disease. Researchers contracted the disease. This virus was named after where the outbreak occurred Marburg, Germany. Ebola was first discovered in 1976 in Africa. There is some evidence that it was originally contracted from bats. Once humans are infected, it spreads from person to person.
Death rate is 23 to 90%. To reduce risk of contracting from another human wear PPE, do not have contact with bodily fluids such as blood, and other secretions. Do not expose yourself to animals out of Africa, which may have the disease.

Currently the medical community is working on a vaccine. Researchers at Howard Hughes Medical Institute have developed at blood test (Virscan) which will tell doctors the patient complete viral history.
