ar·e·na·vi·rus

 (ăr′ə-nə-vī′rəs, ə-rē′nə-)
n.
Any of a family of single-stranded RNA viruses that cause chronic infections in rodents and when transmitted to humans cause various hemorrhagic diseases, including Lassa fever.

[Latin arēna, sand; see arena, virus (so called because when an arenavirus virion is viewed in cross section under an electron microscope, the ribosomes acquired from the host cell appear as fine granules ).]

ar•en•a•vi•rus

(ˌɑr ɛnˈeɪˌvaɪ rəs)
n., pl. -rus•es.
any of various RNA-containing viruses of the family Arenaviridae, usu. transmitted to humans by contact with excreta of infected rodents.
[1971; earlier arenovirus (1970) < Latin (h)arēn(a) sand + -o- + virus; so called from the RNA granules seen in cross sections of the virion]

Lymphocytic choriomeningitis viras (LCMV) is an arenavirus, discovered by Armstrong and Lillie in 1933 (1) that chronically infects small rodents.

Hookipa Biotech AG, a biotech company pioneering a new class of immunotherapeutics and vaccines based on its proprietary arenavirus vector platforms, today announces the award of a fifth major grant from the Austrian Research Promotion Agency (Forschungs-Forderungs-Gesellschaft, FFG), the leading public funding agency for translational research in Austria.
For example, while Leptospira and Lymphocytic choriomeningitis arenavirus are transmitted by urban rodents such as Rattus rattus and Mus muscullus, recent evidence suggests that wild rodents such as the New World Sigmodontins are chronic carriers of these roboviruses.

1] A small number of nosocomial outbreaks have occurred in SA: Marburg virus disease (MVD) in Johannesburg in 1975, CCHF near Cape Town in 1984, EVD in Johannesburg in 1996, and the Lujo virus, a newly identified arenavirus, in Johannesburg in 2008 [7-10] (these are dealt with in detail in the 'Clinical Alert' article in this issue of SAMJ [11]).
Examples include the discovery of a novel arenavirus in liver and kidney transplant tissue (2) and genome reconstruction of an epidemic strain of Shiga toxin-producing Escherichia coli found in stool samples (3).
Examples in which NGS strategies have identified likely causal agents in idiopathic conditions (not all in humans) include Heartland Bunyavirus, titi monkey adenovirus, Bas-Congo virus, Theiler's disease-associated virus, Lujo arenavirus, and many others.
Sometimes an arenavirus, such as the one that causes Lassa hemorrhagic fever, will infect a human.
