Article
Ebola is the common term used for Ebola Virus Disease (EVD) – just one of the lethal Viral Haemorrhagic Fevers (VHFs) seen mainly in Africa. Ebola is a classic disease which can be transmitted to humans from animals (a ‘zoonosis’) with persistence of the virus in reservoir species, such as fruit bats, found in endemic areas. Ebola can cause disease both in humans and non-human primates.
Ebola is not new; it was first identified in 1976 in sub-Saharan Africa. Typically fewer than 500 cases have been reported annually, usually in rural areas, and between 1979 and 1994 there were no cases reported. The Ebola outbreak in West Africa, first reported in March 2014, rapidly became the deadliest outbreak of Ebola.
The current virulence of Ebola, epidemic spread in West Africa including in urban conurbations, and sporadic appearances in many geographic locales including North America, Europe and the Antipodes, mainly through infected travellers and healthcare workers, raises grave concerns of an impending pandemic. Although by far most common in the resource-poor west African countries, with the continually increasing global travel, Ebola is appearing or may appear in most countries globally.
