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 ).]

(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]
