Ebola Virus Disease


​Ebola disease is caused by the Ebola virus and is one of a number of hemorrhagic fever diseases. Ebola disease causes severe illness in which 50-90 percent of those infected die. Ebola disease was first discovered in 1976 in what is now the Democratic Republic of Congo near the Ebola River.

Ebola symptoms include fever, headache, joint and muscle aches, weakness, diarrhea, vomiting, stomach pain and lack of appetite. Some patients have a rash, red eyes, hiccups, cough, sore throat, chest pain, difficulty breathing or swallowing, or bleeding inside and outside the body.

Symptoms usually start 4-10 days after coming into contact with Ebola virus but can occur as early as 2 days to up to 21 days after exposure.

Health care providers caring for Ebola patients and family and friends in close contact with an ill person are at highest risk because they may come into contact with blood or body fluids.
