Flaviviridae

Flaviviridae, commonly flavivirus, flaviviral, and flaviviruses, is a family of enveloped positive-strand RNA viruses which mainly infect mammals and birds. They are primarily spread through arthropod vectors (mainly ticks and mosquitoes). The family gets its name from the yellow fever virus; flavus is Latin for "yellow", and yellow fever in turn was named because of its propensity to cause jaundice in victims. The family has five genera. Diseases associated with the group include: hemorrhagic fever, encephalitis, and the birth defect microcephaly.

Orthoflavivirus (Flavivirus prior to 2023; common name orthoflavivirus, orthoflaviviral or orthoflaviviruses) is a genus of positive-strand RNA viruses in the family Flaviviridae. The 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 (ISFs) such as cell fusing agent virus (CFAV), Palm Creek virus (PCV), and Parramatta River virus (PaRV). While dual-host flaviviruses can infect vertebrates as well as arthropods, insect-specific flaviviruse
