Arenaviruses are enveloped viruses (about 120 nm diameter) with a bi-segmented negative strand RNA genome. The typical image in electronic microscopy showing grainy ribosomal particles (“arena” in latin) inside the virions gave the name to this family of viruses.

In 1933, the first virus of the Arenaviridae family, the Lymphocytic Choriomeningitis (LCM) virus, was isolated in North America from a human with aseptic meningitis. Read more facts about arenavirus
