Hepacivirus"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.) [http://microbewiki.kenyon.edu/index.php/Flaviviridae Accessed July 22,2008] .
They include the following genera:
Flavivirus" (type species " Yellow fevervirus", others include " West Nile virus" and " Dengue Fever")—contains 67 identified human and animal viruses
Hepacivirus" (type species " Hepatitis C virus", the single member)
Pestivirus" (type species " Bovine virus diarrhea", others include classical swine feveror hog cholera)—contains viruses infecting non-human mammals
"Flaviviridae" have monopartite, linear, single-stranded
RNA genomesof positive polarity, 9.6- to 12.3- kilobasein length. The 5'-termini of flaviviruses carry a methylated nucleotidecap, 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.
Major diseases caused by the "Flaviviridae" family include:
Kyasanur Forest disease
Murray Valley encephalitis
St. Louis encephalitis
West Nile encephalitis
Hepatitis CVirus Infection
