Since the natural reservoir for the virus is unknown, how Ebola first appeared in humans is not currently not known. Scientist believe that infection in humans started after exposure to the animal reservoir. After initial infection, the disease can pass from person to person in several ways. Ebola can be transmited through contact with infected blood. Also, needles with infected secretions can provide a route for infection.
