What is Ebola?
The Ebola virus causes viral hemorrhagic fever,
which according to the US Centers for Disease Control and Prevention,
refers to a group of viruses that affect multiple organ systems in the body and
are often accompanied by bleeding.
The virus is named after the Ebola River in the
Democratic Republic of Congo (formerly Zaire), where one of the first outbreaks
occurred in 1976. The same year there was another outbreak in Sudan.
The WHO says there are five different strains of the
virus named after the areas they originated in. Three of these have been
associated with large outbreaks of hemorrhagic fever in Africa.
