arenavirus

 [ah-re´nah-vi″rus]
any member of a family of spherical or pleomorphic RNA viruses containing host cell–derived ribonucleoproteins, including viruses that cause lassa fever and lymphocytic choriomeningitis; the natural hosts are rodents.

Arenavirus

/Are·na·vi·rus/ (ah-re´nah-vi″rus) arenaviruses; a genus of viruses of the family Arenaviridae that includes lymphocytic choriomeningitic (LCM) virus, Lassa virus, and viruses of the Tacaribe complex.

arenavirus

(ăr′ə-nə-vī′rəs, ə-rē′nə-, ə-rē′nə-vī′rəs)
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.

Arenavirus

[er′inəvī′rəs]
a genus of viruses usually transmitted to humans by contact with or inhalation of aerosolized excreta of wild rodents. Individual arenaviruses are identified with specific geographic areas, such as Bolivian hemorrhagic fever in one river valley in Bolivia; Lassa fever in Nigeria, Liberia, and Sierra Leone; and Argentine hemorrhagic fever in two agricultural provinces in Argentina. Arenavirus infections are characterized by a slow onset of fever, sweats, malaise, headache, retro-orbital pain, muscle pain, rash, petechiae, hemorrhage, delirium, hypotension, and ulcers of the mouth. In rare cases in health care and family settings, some arenaviruses are associated with secondary person-to-person infection. Treatment is supportive, such as fluid and electrolyte balance, rest, and adequate nutrition. Preventative measures include rodent control. An effective live attenuated vaccine has been used in Argentina. Further trials with other vaccines are underway.

arenavirus

Any of the family of Arenaviridae of viruses which includes those causing LASSA FEVER and LYMPHOCYTIC CHORIOMENINGITIS. The name derives from the sand-like appearance of the internal granules seen on electron microscopy.
