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.
