First identified in the middle 1970s in the Democratic Republic of Congo, Ebola virus is named after one of Congo’s rivers, and is known to cause an often-fatal hemorrhagic disease in humans and primates, such as monkeys, gorillas and chimpanzees. According to World Health Organization, Ebola viruses are causing death in 25-90% of all clinically ill cases in Africa, the predominant treatment remaining supportive therapy, as there is no approved Ebola therapy yet. Recently, Canadian researchers have announced a breakthrough in the treatment of the Ebola disease, after succeeding in curing several monkeys infected with the Ebola virus.
