Flavivirus

a genus of flaviviruses of worldwide distribution, containing about 75 species in 9 serogroups. It includes the viruses that cause yellow fever, dengue, Japanese B encephalitis, Kyasanur Forest disease, St. Louis encephalitis, tick-borne encephalitis, and West Nile encephalitis. Mosquitoes are the most common vector, with some species being tick-borne and some having no known vector.

flavivirus

A member of the flavivirus genus of the Flaviviridae family. Flaviviruses are arthropod-borne (arbor) viruses and can cause encephalitic or meningitic diseases including Japanese encephalitis, West Nile virus encephalitis, St. Louis encephalitis and Murray Valley encephalitis.
