Ebola virus (formerly officially designated Zaire ebolavirus, or EBOV) is a virus that causes ebola virus disease.
The Zaire ebolavirus is the most dangerous of the five species of Ebola viruses of the Ebolavirus genus.
Ebola virus has been found in African monkeys, chimps and other nonhuman primates.
A milder strain of Ebola has been discovered in monkeys and pigs in the Philippines.
Marburg virus has been found in monkeys, chimps and fruit bats in Africa.
Ebola is a rare but deadly virus that causes bleeding inside and outside the body.
As the virus spreads through the body, it damages the immune system and organs. Ultimately, it causes levels of blood-clotting cells to drop. This leads to severe, uncontrollable bleeding.
Transmission
Ebola virus is transmitted to an initial human by contact with an infected animal's body fluids. Human-to-human transmission can occur via direct contact with blood or bodily fluids from an infected person (including embalming of an infected dead person) or by contact with contaminated medical equipment, particularly needles and syringes.
