Fla·vi·vi·ri·dae

(flā'vī-vī'ri-dē),
A family of enveloped single-stranded positive sense RNA viruses 40-60 mm in diameter formerly classified as the "group B" arboviruses, including yellow fever and dengue viruses; maintained in nature by transmission from arthropod vectors to vertebrate hosts.

Flaviviridae

/Fla·vi·vi·ri·dae/ (fla″vĭ-vir´ĭ-de) the group B arboviruses: a family of RNA viruses with a single-stranded positive-sense RNA genome; there is a single genus, Flavivirus.

Flaviviridae

Virology A large group of small viruses that have their entire life cycle in cytoplasm, without an intermediate DNA form Examples Dengue, Omsk hemorrhagic, St Louis encephalitis, West Nile, yellow fever viruses

Flaviviridae

a family of viruses comprising three genera, Flavivirus, Pestivirus, and Hepacivirus. They are single-stranded, plus sense RNA viruses. The type species of the genus Flavivirus, which are arthropod borne viruses, is the yellow fever virus of humans (flavi = yellow); other viruses cause encephalitis in humans and some cause encephalitis in animals. Amongst the viruses in the genus which affect animals are: West Nile virus, St. Louis encephalitis—a disease of humans but the virus has been isolated from animals; Japanese B encephalitis virus; California encephalitis of humans, but viremia detectable in feral animals; louping ill; Central European tickborne fever and Murray Valley encephalitis, both diseases of humans and the viruses that occur in small ruminants; wesselsbron disease, Israeli turkey meningoencephalitis; Powassan disease; and the Tahyna virus. The genus Pestivirus includes classical swine fever (hog cholera), bovine virus diarrhea-mucosal disease and ovine border disease viruses. The genus Hepacivirus includes human hepatitis C virus. Pestiviruses and hepaciviruses are not arthropod borne.
