MeSH Heading: Influenza A virus
Tree Number(s): B04.820.480.968.405.400
Unique ID: D009980
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D009980
Annotation: infection: coordinate IM with INFLUENZA, HUMAN (IM) in humans or ORTHOMYXOVIRIDAE INFECTIONS (IM) in animals other than birds; infection in birds = INFLUENZA IN BIRDS; ALPHAINFLUENZAVIRUS is also available
Scope Note: The type species of the genus ALPHAINFLUENZAVIRUS that causes influenza and other diseases in humans and animals. Antigenic variation occurs frequently between strains, allowing classification into subtypes and variants. Transmission is usually by aerosol (human and most non-aquatic hosts) or waterborne (ducks). Infected birds shed the virus in their saliva, nasal secretions, and feces.
