Ebola Virus Disease

Ebola Virus Disease (EVD) is a rare and deadly disease in people and nonhuman primates. The viruses that cause EVD are located mainly in sub-Saharan Africa. People can get EVD through direct contact with an animal with EVD (bat or nonhuman primate) or a sick or dead person with EVD.

How is Ebola spread?

Ebola is spread through direct contact of the following items.

  • Blood or Secretions of someone who is:

    • Ill and Exhibiting symptoms or

    • By exposure to objects such as needles that have been infected with contaminated secretions.
