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 slow onset, fever, muscle pain, rash, petechiae, hemorrhage, delirium, hypotension, and ulcers of the mouth. Some arenaviruses are associated with secondary person-to-person infection. Treatment is supportive; there is no specific antimicrobial agent or vaccine. Fluid and electrolyte balance, rest, and adequate nutrition are the goals of treatment.
