The Orthomyxoviridae (orthos, Greek for "straight"; myxa, Greek for "mucus") are a family of RNA viruses that includes five genera: Influenzavirus A, Influenzavirus B, Influenzavirus C, Isavirus and Thogotovirus. A sixth has recently been described. The first three genera contain viruses that cause influenza in vertebrates, including birds (see also avian influenza), humans, and other mammals.

The Orthomyxoviridae (orthos, Greek for "straight"; myxa, Greek for "mucus") are a family of RNA viruses that includes five genera: Influenzavirus A, Influenzavirus B, Influenzavirus C, Isavirus and Thogotovirus. A sixth has recently been described. The first three genera contain viruses that cause influenza in vertebrates, including birds (see also avian influenza), humans, and other mammals. Isaviruses infect salmon; thogotoviruses infect vertebrates and invertebrates, such as mosquitoes and sea lice.
The three genera of Influenzavirus, which are identified by antigenic differences in their nucleoprotein and matrix protein infect vertebrates as follows:
In a phylogenetic-based taxonomy the "RNA viruses" includes the "negative-sense ssRNA viruses" which includes the Order "Mononegavirales", and the Family "Orthomyxoviridae" (among others). The genera-associated species and serotypes of Orthomyxoviridae are shown in the following table.
There are three genera of influenza virus:...
