What is Ebola Virus Disease (EVD)?
Ebola virus disease (also known as Ebola hemorrhagic fever) is a very serious, often deadly disease in humans and in infected animals such as monkeys, gorillas, and chimpanzees. A very large outbreak of EVD began in March, 2014 and is continuing. What are the symptoms of EVD? Symptoms may appear anywhere from two to 21 days following exposure, but often appear between eight and 10 days following exposure.
People are contagious as long as their blood and bodily fluids contain the virus. People who do not have symptoms are not contagious.
How is EVD spread?
It is not known how EVD is first spread to humans, but it is thought to be spread through close contact with the blood, secretions or other body fluids of an infected animal. Once the virus has been spread to humans, it is spread from person to person by contact with the blood or body fluids (e.g. stool, urine, sweat, semen, and breast milk) of an infected person; by contact with an object that is contaminated with the infected body fluids (e.g., used needles); or by contact with a deceased EVD patient.
