How does the Ebola virus manage to survive through periods between epidemics (e.g., 1979-1994 when no epidemic was documented)?

  1. Ebola virus disease (EVD) is a zoönosis, in other words it is an animal disease that occasionally jumps into humans. It affects many primates other than humans, but the reservoir species is now thought to be several species of bats. A true reservoir species does not suffer from the disease (or to a lesser extent), and the agent (a filovirus) can probably exist for long periods in a bat colony.

    Hence, EVD probably cannot be eradicated, as smallpox was. Smallpox, polio, measles, mumps are examples of diseases for which no other species can act as a reservoir.
