Etymology

The order name ''Articulavirales'' derives from Latin meaning "segmented" (alluding to the segmented genome of member viruses) added to the suffix for virus orders ''-virales''. The class name ''Insthoviricetes'' is a
portmanteau A portmanteau word, or portmanteau (, ) is a blend of words


Genome

Member viruses have segmented, negative-sense, single-stranded RNA genomes.


Classification

The order ''Articulavirales'' contains two families and eight genera: * '' Amnoonviridae'' ** '' Tilapinevirus'' * '' Orthomyxoviridae'' ** ''
Alphainfluenzavirus '' A virus'' (''IAV'') causes influenza in birds and some mammals, and is the only species of the genus ''Alphainfluenzavirus'' of the virus family '' Orthomyxoviridae''. Strains of all subtypes of influenza A virus have been isolated from wi ...

Betainfluenzavirus ''Influenza B virus'' is the only species in the genus ''Betainfluenzavirus'' in the virus family '' Orthomyxoviridae''. Influenza B virus is known only to infect humans and seals. This limited host range is apparently responsible for the lack ...

Isavirus Infectious salmon anemia (ISA) is a viral disease of Atlantic salmon (''Salmo salar'') caused by ''Salmon isavirus''. It affects fish farms in Canada, Norway, Scotland and Chile, causing severe losses to infected farms. ISA has been a World O ...
