Ebola virus, discovered in 1976 during an outbreak in Zaire (now Democratic Republic of the Congo), was first isolated from Myriam Louise Ecran, a 42-year-old Belgian nursing sister working at the Yambuku Mission Hospital who died caring for people with this unknown disease. When the international commission considered the name “Yambuku virus,” Karl Johnson and Joel Breman noted that naming the Lassa virus after the Nigerian village where it was discovered brought stigma to the community. Johnson suggested naming the virus after a nearby river, and the rest of the commission agreed (Figure 1).. The Belgian name for the river, l’Ebola, is actually a corruption of the indigenous Ngbandi name Legbala, meaning “white water” or “pure water” (J.G. Breman, L.E. Chapman, F.A. Murphy, P.E. Rollin, pers. comm.) (Figure 2).

The Ebola virus, originally described as “Marburg like,” was determined to be a related filovirus (from the Latin filum, “thread”), named for the elongated, flexible shape. The virus was first described in 3 back-to-back articles in The Lancet in 1977.
