EBOLA: Disease which causes hemorrhagic fever. It was first seen in the Ebola river region of northern Zaire. The sickness is caused by the Ebola virus and is usually fatal. Little is known about the disease (year 2000). Infections can be transmitted via airborne particles and body secretions such as mucus, saliva and blood, and can be passed through a simple handshake. Four days after exposure, flu-like symptoms set in, followed by bloody diarrhea and vomiting. Ten to 15 days later, the victims "bleed out" through the nose, mouth and eyes. Blood and other bodily fluids also begin seeping through the skin, producing painful blisters. How the first person known to have contracted Ebola in Uganda - became infected is a mystery. In fact, researchers have no idea where the virus lives in between outbreaks, which are often years and hundreds of miles apart. While they know it resides in a host animal or insect that it does not kill, they have not identified the host.
