82170-2Influenza virus B RNA [Presence] in Nasopharynx by NAA with non-probe detectionActive

Term Description

Qualitative detection of nucleic acid sequences in Influenza virus B RNA in nasopharyngeal swabs by target amplification and non-probe detection methods, such as melt curve analysis. This term was created for, but not limited in use to, the submitter's test kit, FilmArray Respiratory Panel (RP) v1.7.

Part Description

LP14240-3   Influenza virus B
Influenza virus from the family Orthomyxoviridae are enveloped negative-strand RNA viruses with segmented genomes containing seven to eight gene segments. Of the five genera in the family, only influenza A virus (IAV), influenza B and C viruses are medically relevant to humans. Influenza A and B viruses have a similar structure whereby these viruses each contain eight discrete single-stranded RNA gene segments, each encoding at least one protein. While having a close phylogenetic relationship, influenza virus types A and B manifest very differently. While IAV infects birds, humans and other mammals, influenza B only infects humans and seals. Although both viruses cause human respiratory infection seasonally in temperate climate regions and more continually in the tropics, influenza B is normally less prevalent and causes less severe disease than IAV viruses. Research is ongoing to determine the evolutionary and epidemiological factors that shape the genetic diversity of influenza B virus.
