Ebola first appeared in 1976 in simultaneous outbreaks in Nzara, Sudan, and in Yambuku, DRC. The latter was in a village situated near the Ebola River, from which the disease takes its name. Fruit bats are considered to be the natural host of the Ebola virus. The case-fatality rate varies from 25 to 90 percent, depending on the strain.
If contracted, Ebola is one of the world’s most deadly diseases. It is a highly infectious virus that can kill up to 90 percent of the people who catch it, causing terror among infected communities.
Since the Ebola outbreak in West Africa was officially declared on March 22 in Guinea, it has claimed 4,919 lives in the region. The outbreak is the largest ever, and is currently affecting four countries in West Africa: Mali, Guinea, Liberia, and Sierra Leone (MSF).
