Articulavirales is an order of segmented negative-strand RNA viruses which infect invertebrates and vertebrates. [2] It includes the family of influenza viruses which infect humans. It is the only order of viruses in the monotypic class Insthoviricetes. [3] The order contains two families and eight genera. [1] Metatranscriptomics of aquatic animal samples paired with phylogenetics suggests that Articulavirales exhibits complex cross-species virus transmission and virus-host co-divergence over deep evolutionary time scales. Potentially originating in ancient aquatic animals at least 600 Mya. [4]
The order name Articulavirales derives from Latin articulata meaning "segmented" (alluding to the segmented genome of member viruses) added to the suffix for virus orders -virales. [3] The class name Insthoviricetes is a portmanteau of member viruses "influenza, isavirus, and thogotovirus" added to the suffix -viricetes for virus classes. [3]
Member viruses have segmented, negative-sense, single-stranded RNA genomes. [2]
The order Articulavirales contains two families and eight genera: [1]
