The Marburgvirus is the taxonomic home of Marburg marburgvirus, whose members are the two known marburgviruses, and . Both viruses cause Marburg virus disease in and nonhuman , a form of viral hemorrhagic fever. Both are , World Health Organization Risk Group 4 Pathogens (requiring ), National Institutes of Health/National Institute of Allergy and Infectious Diseases Category A Priority Pathogens, Centers for Disease Control and Prevention , and are listed as Biological Agents for Export Control by the .


Use of term
The genus Marburgvirus is a virological taxon included in the family , order . The genus currently includes a single species, Marburg marburgvirus. The members of the genus (i.e. the actual physical entities) are called marburgviruses. The name Marburgvirus is derived from the city of in , (where was first discovered), and the taxonomic suffix -virus (which denotes a virus genus). Even though the virus was named after the city of Marburg, Dr. Ana Gligić, lead virologist at a laboratory in , was first who managed to isolate the virus. NOTE: Marburgvirus is pronounced , and Marburg marburgvirus is pronounced . According to the rules for taxon naming established by the International Committee on Taxonomy of Viruses (ICTV), the name Marburg marburgvirus is always to be , , never abbreviated, and to be preceded by the word "species". The names of its members (Marburg marburgviruses) are to be capitalized, are not italicized, and used without articles; according to Kuhn.


Previous designations
Until 1998, the family contained only one genus, Filovirus. Once it became clear that marburgviruses and ebolaviruses are fundamentally different, this genus was abolished and a genus "Marburg-like viruses" was established for marburgviruses. In 2002, the genus name was changed to Marburgvirus,

and in 2010 and 2011 the genus was emended.

Genus inclusion criteria
A virus that fulfills the criteria for being a member of the family is a member of the genus Marburgvirus if
  • its genome has one gene overlap
  • its fourth gene ( GP) encodes only one protein (GP1,2) and cotranscriptional editing is not necessary for its expression
  • peak infectivity of its virions is association with particles ≈665 nm in length
  • its genome differs from that of by <50% at the nucleotide level
  • its virions show almost no antigenic cross reactivity with ebolavirions

Marburg marburgvirus
The species was introduced in 1998 as Marburg virus.
(2025). 9780123702005, Academic Press.

Because of easy confusion with its virus member , the species name was changed to Lake Viktoria marburgvirus in 2005.

In 2010, it was proposed to change the name to Marburg marburgvirus, and this proposal was accepted in early 2012 by the ICTV.

Marburg marburgvirus (also referred to as Lake Victoria marburgvirus) is a virological taxon (i.e. a man-made concept) included in the genus Marburgvirus, family , order . The species has two members, and . The members of the species (i.e. the actual physical entities) are called Marburg marburgviruses. The name Marburg marburgvirus is derived from the city of in , (where was first discovered), and the taxonomic marburgvirus (which denotes a marburgvirus species).


Species inclusion criteria
A virus that fulfills the criteria for being a member of the genus Marburgvirus is a member of the species Marburg marburgvirus if it has the properties of marburgviruses (because there is currently only marburgvirus species) and if its genome differs from that of (variant Musoke) by <30% at the nucleotide level.
