- Ebola, also known as Ebola virus disease (EVD) or Ebola hemorrhagic fever (EHF), is a viral hemorrhagic fever of humans and other primates caused by ebolaviruses.
- It is transmitted to people from wild animals and spreads in the human population through human to human transmission.
- Ebola virus was first discovered in 1976 near the Ebola River (the present Democratic Republic of Congo)
- Transmission: Fruit bats of the Pteropodidae family are natural Ebola virus hosts.
- Animal to Human Transmission: Ebola is introduced into the human population through close contact with the blood, secretions, organs or other bodily fluids of infected animals such as fruit bats, chimpanzees, gorillas, found ill or dead or in the rainforest.
