Algselt klassifitseeriti flaviviirused arboviiruste hulka. Flaviviiruste perekond koosneb rohkem kui 70 erinevast viirusest, millest umbes 50% levitavad sääsed.
Flaviviruses have enveloped and spherical virions (virus particles) that are between 40 and 60 nm (1 nm = 10−9 metre) in diameter. The flavivirus genome consists of nonsegmented single-stranded positive-sense RNA (ribonucleic acid). Flaviviridae contains three genera: Flavivirus, Hepacivirus, and Pestivirus.
