Ebola Disease Basics
What it is
Ebola disease is caused by a group of viruses, known as orthoebolaviruses (formally ebolavirus)1.
How to prevent ebola
These viruses can cause serious illness that, without treatment, can cause death. Orthoebolaviruses were discovered in 1976 in the Democratic Republic of the Congo and are found primarily in sub-Saharan Africa.
Types
There are four orthoebolaviruses that cause illness in people:
- Ebola virus (species orthoebolavirus zairense) causes Ebola virus disease.
- Sudan virus (species orthoebolavirus sudanense) causes Sudan virus disease.
- Taï Forest virus (species orthoebolavirus taiense) causes Taï Forest virus disease.
- Bundibugyo virus (species orthoebolavirus bundibugyoense) causes Bundibugyo virus disease.
Some orthoebolaviruses do not cause illness in people.
Reston virus (species Orthoebolavirus restonense) can cause illness in nonhuman primates and pigs. Bombali virus (species Orthoebolavirus bombaliense) was identified in bats, but scientists don't know if it causes illness in animals or people.
