arena virus

Arena virus is an enveloped, spherical to pleomorphic ssRNA virus 120nm in diameter that causes acute viral hemorrhagic fever. It is transmitted from rodents to humans through contaminated food or rodent consumption and between humans through inoculation or secretions. Symptoms include fever, shock, and increased blood vessel permeability. Prevention focuses on interrupting transmission routes while treatment involves immunotherapy and intravenous ribavirin administration. A vaccine exists for the Junín virus strain using vaccinia virus vectors.
