Ebola Virus: A notoriously deadly virus that causes severe symptoms, the most prominent being high fever and massive internal bleedingEbola virus kills as many as 90% of the people it infects. It is one of the viruses that is capable of causing hemorrhagic (bloody) fever. Epidemics of Ebola virus have occurred mainly in African countries including Zaire (now the Democratic Republic of Congo), Gabon, Uganda, the Ivory Coast, and Sudan. Ebola virus is a hazard to laboratory workers and anyone who is exposed to it. Ebola virus is transmitted by contact with blood, feces, or body fluids from an infected person or by direct contact with the virus, as in a laboratory. The incubation period --the period between contact with the virus and the appearance of symptoms -- ranges from 2 to 21 days. The initial symptoms are usually high fever, headache, muscle aches, stomach pain, and diarrhea. There may also be sore throathiccups, and red and itchy eyes.
