Ebola is also known as Ebola Virus Disease (EVD) or Ebola Hemorrhagic Fever (EHF). There are five Ebola subspecies, four of which are known to cause the disease. Ebola viral disease is a severe, often fatal disease that affects humans and some animals (like monkeys, gorillas, and chimpanzees). Ebola was first identified in 1976 near the Ebola River in the country now known as the Democratic Republic of the Congo. Since then, outbreaks have appeared sporadically in several African countries.
