What is it

Ebola is a rare and deadly disease caused by infection with one of the Ebola virus species1. Ebola can cause disease in humans and nonhuman primates (monkeys, gorillas, and chimpanzees)1. Ebola viruses are found in several African countries, it was first discovered in 1976 and since then outbreaks have appeared sporadically in Africa1.

Who is at risk

People most at risk are those in close contact with infected people including2:

  • Hospital or laboratory staff who do not use proper personal protective equipment when caring for Ebola patients

  • Hemorrhaging (bleeding from inside and outside the body)

How is it spread

Ebola is caused by infection with a virus of the family Filoviridae, genus Ebolavirus. there are five identified Ebola virus species, four of which are known to cause disease in humans1.

Ebola can be spread through contact with1:

  • Blood, body tissue or fluids from an infected person
  • Medical equipment contaminated with infected body fluids, such as needles
  • Medical personnel in health care settings who do not wear proper protective equipment including masks, gowns and gloves
  • Infected animals including bats, gorillas and monkeys
