• Genus Flavivirus (type species Yellow fever virus, others include West Nile virus)
• Genus Hepacivirus (type species Hepatitis C virus)

The genome of the Flaviviridae viruses is a monopartite, linear, single-stranded RNA of positive sense that is 10,000-11,000 nucleotides long. The 5'-terminus carries a methylated nucleotide cap or a genome-linked protein. The virus itself is enveloped and spherical, about 40-60 nm in diameter.
