Flaviviridae

The Flaviviridae are a family of viruses that are primarily spread through arthropod vectors (mainly ticks and mosquitoes). They include 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, the single member)
 * Genus Pestivirus (type species Bovine virus diarrhea, others include classical swine fever or hog cholera)—contains viruses infecting non-human mammals

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.

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
