Die Gattungen Alpha-, Beta-, Gamma- und Deltainfluenzavirus aus der Familie Orthomyxoviridae sind behüllte Viren mit einer einzelsträngigen, segmentierten RNA von negativer Polarität als Genom. Unter den Gattungen finden sich auch die Erreger der Influenza oder „echten“ Grippe. Zu medizinischen Aspekten der Influenzaviren und Grippe-Erkrankung siehe Influenza. Gemäß International Committee on Taxonomy of Viruses (ICTV, Stand: November 2018) haben alle vier Gattungen jeweils nur eine Spezies, und zwar der Reihe nach Influenza A-Virus (FLUAV) bis Influenza D-Virus (FLUDV).

Influenza A virus, or IAV, is a pathogen with strains that cause seasonal flu in humans; it can also infect birds and some mammals. Strains of IAV circulate constantly in bats, pigs, horses, and dogs, while other mammals may be infected occasionally. It has also been the cause of a number of pandemics, most notably the Spanish Flu pandemic from 1918–1920.
Subtypes of IAV are defined by the combination of the molecules on the surface of the virus which provoke an immune response; for example, "H1N1" denotes a subtype that has a type-1 hemagglutinin (H) protein and a type-1 neuraminidase (N) protein. Variations within subtypes affect how easily the virus spreads, the severity of illness, and its ability to infect different hosts. The virus changes through mutation and genetic reassortment, allowing it to evade immunity and sometimes jump between species.
