ar·bo·vi·ral \-rəl\ adjective


noun    (Concise Encyclopedia)

Any of a large group of viruses that develop in arthropods (chiefly mosquitoes and ticks). The name derives from “arthropod-borne virus.” The spheroidal virus particle is encased in a fatty membrane and contains RNA; it causes no apparent harm to the arthropod host. Arboviruses are transmitted by bites to vertebrate hosts, in which they establish infections and complete their growth cycle; they include the agents responsible for yellow fever and equine encephalitis. See also togavirus.
