 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]
