Overview
The Ebola virus was named after the Ebola River Valley in the Democratic Republic of the Congo (formerly Zaïre), near the site of a 1976 outbreak at a mission run by Flemish nuns.[1] Since the initial discovery of the virus, five subtypes have subsequently been identified.
Historical Perspective
Discovery
- The Ebola virus was first recognized in 1976 as a result of outbreaks of Ebola hemorrhagic fever in Zaire and Sudan.
- The fist description of ebola virus disease was made by Doctor Ngoy Mushola, in his daily log:
| “ | The illness is characterized with a high temperature of about 39°C, hematemesis [the vomiting of blood], diarrhea with blood, retrosternal abdominal pain, prostration with "heavy" articulations, and rapid evolution death after a mean of three days... | ” |
- The virus was named after the Ebola river located in Yambuku, Democratic Republic of the Congo (formerly Zaire).
- The first outbreaks occurred almost simultaneously in Sudan between June and November 1976, due the so-called Sudan ebolavirus, and in Democratic Republic of the Congo (formerly Zaire) between August and November 1976 due the so-called Ebola Zaire.
- The table below summarizes the ebola virus strains identified until now:
| Ebola Virus Strain | Place of Discovery | Date Identified |
|---|---|---|
| Sudan ebolavirus | Nzara and Maridi, Sudan | Between June and November 1976 |
| Zaire ebolavirus | Yambuku, Democratic Republic of the Congo | Between August and November 1976 |
| Reston ebolavirus | Reston, Virginia, US. | November 1989 |
| Ivory Coast ebolavirus | Tai Forest, Ivory Coast. | November 1994 |
| Bundibugyo ebolavirus | Bundibugyo District, Uganda | November 2007 |
Notable Cases
- Nurse Mayinga N'Seka was the index case in an Ebola epidemic in Democratic Republic of the Congo and may represent the only case of airborne ebola virus infection.
- The non-fatal case of a Swiss 34-year-old female ethologist, in the Taï National Park, Ivory Coast, was due to an infection by what was later recognized as a new strain of ebola virus after she performed a necropsy on a chimpanzee found dead with signs of hemorrhage.[2]
Bioterrorism
A potential risk associated with the Ebola virus is bioterrorism. Ebola does not have a vaccine, therefore it would be a good candidate for a major bioterrorist attack. Given the fact that Ebola is lethal and has no approved vaccine or treatment, it is classified as a Biosafety Level 4 agent, as well as a Category A bioterrorism agent[3] and a select agent by the CDC.
