Genus: Orthoflavivirus
Family: Flaviviridae
Genus: Orthoflavivirus
Distinguishing features
The 5′-end of the genome possesses a type I cap (m7GpppAmp) not seen in viruses of the other genera. Most orthoflaviviruses are transmitted to vertebrate hosts by arthropod vectors, mosquitoes or ticks, in which they replicate actively. Some orthoflaviviruses transmit between rodents or bats without known arthropod vectors.
