noun, plural: flaviviruses
(virology) A taxonomic genus belonging to the family Flaviviridae that includes species (e.g. medically-important arboviruses such as dengue virus, yellow fever virus, zika virus, and West Nile virus) with positive-sense, single-stranded RNA of about 10,000 to 11,000 bases encased in an icosahedral envelope of about 40 – 65 nm in diameter
Flaviviridae is a taxonomic family comprised of viruses containing monopartite, linear, single-stranded RNA enveloped with icosahedral, spherical structure (about 40-60 nm in diameter). This family includes four genera: Flavivirus, Hepacivirus, Pegivirus, and Pestivirus. The genus Flavivirus includes medically-important species such as the yellow fever virus, dengue virus, zika virus, and West Nile virus. The name Flaviviridae is derived from the Flavivirus species causing the yellow fever disease. These viruses are characterized by having a positive-sense, single-stranded RNA of about 10,000 to 11,000 bases encased in an icosahedral envelope (about 40 – 65 nm in diameter).
This genus is also known as group B arboviruses, making use of mosquitoes or ticks as arthropod vector to reach their hosts. For instance, dengue virus, zika virus, yellow fever virus, and West Nile virus are spread through infected mosquitoes. Flavivirus spread by infected tick is the tick-borne encephalitis virus known to infect a range of mammalian hosts, e.g. ruminants, birds, rodents, horses, humans, etc.
