Articulavirales is an order of segmentednegative-strand RNA viruses which infectinvertebrates andvertebrates.[2] It includes thefamily of influenza viruses which infect humans. It is the only order ofviruses in themonotypicclassInsthoviricetes.[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 nameArticulavirales derives from Latinarticulata meaning "segmented" (alluding to the segmented genome of member viruses) added to the suffix for virus orders-virales.[3] The class nameInsthoviricetes is aportmanteau of member viruses "influenza, isavirus, andthogotovirus" added to the suffix-viricetes for virus classes.[3]
Member viruses have segmented, negative-sense, single-stranded RNA genomes.[2]
The orderArticulavirales contains the following two families and 10 genera:[5]
