- Although it was never discovered how the first human became infected with the Ebola virus in 1976, researchers theorised that it was through contact with an infected animal.
- According to research, Ebola first spreads to humans by contact with the skin or body fluids of an infected animal (like a monkey, chimpanzee or fruit bat), then it moves from person to person through the same means.
- A person who has Ebola but no symptoms cannot spread the disease. Persons with Ebola are most contagious in the later stages of the disease.
- Ebola is transmitted through direct contact with broken skin, tissues, blood or other bodily fluid (secretion such as stool, saliva, urine and semen) of infected persons or animals.
- The incubation period – that is, the time interval from infection with the virus to onset of symptoms – is two to 21 days.
