Flavivirus |

The Flaviviridae are a family of viruses that are primarily spread through arthropod vectors (mainly ticks and mosquitoes). The family gets its name from Yellow Fever virus, a type virus of Flaviviridae; flavus means yellow in Latin. (Yellow fever in turn was named because of its propensity to cause jaundice in victims.).[1]
Flaviviridae have monopartite, linear, single-stranded RNA genomes of positive polarity, 9.6- to 12.3-kilobase in length. The 5'-termini of flaviviruses carry a methylated nucleotide cap, while other members of this family are uncapped and encode an internal ribosome entry site. Virus particles are enveloped and spherical, about 40-60 nm in diameter.
Taxonomy
This family includes the following genera:
- Genus Flavivirus (type species Yellow fever virus, others include West Nile virus and Dengue Fever)—contains 67 identified human and animal viruses
- Genus Hepacivirus (type species Hepatitis C virus,[2] the single member)
- Genus Hepatitis G Virus (The GB agent and the hepatitis G virus (HGV))
- Genus Pestivirus (type species bovine viral diarrhea virus, others include classical swine fever or hog cholera)—contains viruses infecting non-human mammals
Clinical importance
Major diseases caused by the Flaviviridae family include:
- Dengue fever
- Japanese encephalitis
- Kyasanur Forest disease
- Murray Valley encephalitis
- St. Louis encephalitis
- Tick-borne encephalitis
- West Nile encephalitis
- Yellow fever
- Hepatitis C Virus Infection
