Question: How does Ebola spread and which virus causes its spread?

Bernerd Fulanda answered on 5 Jul 2017:

Ebola is caused by the Ebola virus disease (EVD), formerly known as Ebola haemorrhagic fever; a severe, often fatal illness in humans
The virus is transmitted to people from wild animals and spreads in the human population through human-to-human transmission.
It is thought that fruit bats of the Pteropodidae family are natural Ebola virus hosts.
Ebola is introduced into the human population through close contact with the blood, secretions, organs or other bodily fluids of infected animals such as chimpanzees, gorillas, fruit bats, monkeys, forest antelope and porcupines found ill or dead or in the rainforest.
Ebola then spreads through human-to-human transmission via direct contact (broken skin or mucous membranes) with the blood, secretions, organs or other bodily fluids of infected people, and with surfaces and materials (e.g. bedding, clothing) contaminated with these fluids; that means the virus can also be sexually transmitted
