LP14402-9   Influenza virus A+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. Aquatic birds harboring avian IAV are the likely natural reservoir for all known IAV subtypes and are probably the original source of all human pandemic IAV strains. IAV maintained in wild birds have been associated with stable host switch events to novel hosts including most often to domestic poultry but also to horses, swine, toothed whales and humans, among other species. Although influenza virus B has been isolated from seals, type B is isolated almost always from humans. Influenza C virus has been isolated from pigs and dogs. While influenza B and C virus also cause illness in humans, host switch events and high mutation rates among IAV types causes respiratory infections in humans ranging from asymptomatic to fatal and are the cause of the influenza pandemics in the 20th and 21st centuries. Pandemics are attributed to "novel" viruses which possess a viral hemagglutinin (HA) to which humans do not have immunity. [PMID:25812763] [CDC:flu/about/viruses/types] Source: Regenstrief LOINC
