The Congo saw 318 cases of infections in one month alone in that same year, which caused 280 deaths.
There were further outbreaks in the two countries in 1977 and 1979.
Since then, over 1,500 cases have been spotted altogether, with about 1,000 of those ending in death.
What's it got to do with monkeys?
It's thought Ebola is carried by monkeys too - their numbers have been badly affected by the virus.
But they were infected from another source, which scientists aren't sure about yet.
Have there been bad outbreaks recently?
There have been more recent outbreaks including:
- 1994-95: One human case and several cases in chimpanzees in Côte d'Ivoire
- 1995: 315 human cases, 244 died in the Democratic Republic of the Congo
- 1994 and 1996: First human cases in Gabon
- 2000: Outbreak in northern Uganda.
What are the symptoms?
Symptoms of Ebola happen fast.
This is usually followed by more serious symptoms:
- Sudden fever
- Muscle pain
- Sore throat
- Bad kidney and liver function
- Internal and external bleeding - this is where the "haemorrhagic" bit comes in.
How do you get it?
In a similar way to HIV, you can catch it through direct contact with the body fluids of an infected person.
