Abstract excerpt
The genus Orthoflavivirus within the family Flaviviridae includes mosquito-borne flaviviruses (MBFs) and dual-host affiliated insect-specific flaviviruses (dISFs). MBFs infect both vertebrates and mosquitoes, while dISFs are thought to infect only mosquitoes, despite their phylogenetic proximity to MBFs. Some dISFs have been shown to be capable of infecting mammalian cells in the setting of a suppressed immune...
