  arborvirus
       n : a large heterogeneous group of RNA viruses divisible into
           groups on the basis of the virions; they have been
           recovered from arthropods, bats, and rodents; most are
           borne by arthropods; they are linked by the epidemiologic
           concept of transmission between vertebrate hosts by
           arthropod vectors (mosquitoes, ticks, sandflies, midges,
           etc.) that feed on blood; they can cause mild fevers,
           hepatitis, hemorrhagic fever, and encephalitides [syn: arbovirus]
