Ebola virus was first introduced as a possible new strain of Marburg virus in 1977 by two different research teams. At the same time, a third team introduced the name Ebola virus.In 2000, the virus name was changed to Zaire Ebola virus, and in 2002 to Zaire ebolavirus.However, most scientific articles continued to refer to Ebola virus or used the terms Ebola virus and Zaire ebolavirus in parallel. Consequently, in 2010, the name Ebola virus was reinstated. Previous abbreviations for the virus were EBOV Z (for Ebola virus Zaire) and most recently ZEBOV (for Zaire Ebola virus or Zaire ebolavirus). In 2010, EBOV was reinstated as the abbreviation for the virus.
