context_page_description: Flavivirus is a genus of viruses in the family Flaviviridae. This genus includes the West Nile virus, dengue virus, tick-borne encephalitis virus, yellow fever virus, Zika virus and several other viruses which may cause encephalitis, as well as insect-specific flaviviruses such as cell fusing agent virus, Palm Creek virus, and Parramatta River virus.
  Flaviviruses are named from the yellow fever virus, the type virus for the family; the word flavus means "yellow" in Latin and the yellow fever in turn is named from its propensity to cause yellow jaundice in victims.
  Flaviviruses share several common aspects: common size, symmetry, nucleic acid, and appearance in the electron microscope.
  Most of these viruses are primarily transmitted by the bite from an infected arthropod, and hence are classified as arboviruses. Human infections with most of these arboviruses are incidental, as humans are unable to replicate the virus to high enough titers to reinfect the arthropods needed to continue the virus lifecycle – humans are then a dead end host. The exceptions to this are the yellow fever, dengue, and zika viruses.
context_section_description: The (+) sense RNA genome of Flavivirus contains 5' and 3' untranslated regions (UTRs).
