Influenza virus D is a genus in the virus family Orthomyxoviridae, which includes the viruses that cause influenza. The species in this genus is called Influenza D virus. Influenza D viruses are known to infect pigs and cattle; no human infections from this virus have yet been observed. First isolated from pigs in 2011, the virus was categorized as a new genus of Orthomyxoviridae in 2016, distinct from the previously-known Influenzavirus C genus; before then, Influenzavirus D was thought to be a subtype of Influenzavirus C. Cases of infections from the Type D virus are rare compared to Types A, B, and C. Similar to Type C, Type D has 7 RNA segments and encodes 9 proteins, while Types A and B have 8 RNA segments and encode at least 10 proteins.
