influenza type D virus
Also known as: Influenzavirus D
Quick Summary
Influenza D viruses are a type of influenza virus belonging to the family Orthomyxoviridae. While influenza types A, B, and C can infect humans and cause illness, influenza D viruses have primarily been observed in pigs and cattle and are not known to infect humans.1
These viruses, like other influenza viruses, are RNA viruses. Influenza viruses are classified into types A, B, C, and D, which, despite causing similar symptoms, are antigenically unrelated, meaning infection with one type does not provide immunity against others.21
