MeSH Heading: Influenza B virus
Tree Number(s): B04.820.480.968.407.410
Unique ID: D009981
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D009981
Annotation: infection: coordinate IM with INFLUENZA, HUMAN (IM) in humans or ORTHOMYXOVIRIDAE INFECTIONS (IM) in animals; BETAINFLUENZAVIRUS is also available
Scope Note: Species of the genus BETAINFLUENZAVIRUS that cause HUMAN INFLUENZA and other diseases primarily in humans. Antigenic variation is less extensive than in type A viruses (INFLUENZA A VIRUS) and consequently there is no basis for distinct subtypes or variants. Epidemics are less likely than with INFLUENZA A VIRUS and there have been no pandemics. Previously only found in humans, Influenza B virus has been isolated from seals which may constitute the animal reservoir from which humans are exposed.
Entry Term(s): Betainfluenzavirus influenzae; FLUBV; Human Influenza B Virus; Influenza Viruses Type B; Influenza virus type B; Orthomyxoviruses Type B
