Avian influenza, also known as avian flu or bird flu, is a disease caused by the influenza A virus, which primarily affects birds but can sometimes affect mammals including humans. [1] Wild aquatic birds are the primary host of the influenza A virus, which is enzootic (continually present) in many bird populations.
Avian influenza virus can survive for 100 days in distilled water at room temperature, and 200 days at 17 °C (63 °F). The avian virus is inactivated more quickly in manure, but can survive for up to two weeks in feces on cages. Avian influenza viruses can survive indefinitely when frozen. [57]
At the present moment, we are at phase 3 on the scale, meaning a new influenza virus subtype is causing disease in humans, but is not yet spreading efficiently and sustainably among humans. [29] So far, H5N1 infections in humans are attributed to bird-to-human transmission of the virus in most cases.
The disease presents in two very different forms: acute and chronic. Birds with chronic avian cholera, more common in domestic fowl, exhibit prolonged illness with more localized infections. Chronic infection has been demonstrated in snow geese, and these individuals are believed to be long term migrating reservoirs for the disease.
Virulent Newcastle disease (VND), formerly exotic Newcastle disease, [1] is a contagious viral avian disease affecting many domestic and wild bird species; it is transmissible to humans. [2] Though it can infect humans, most cases are non-symptomatic; rarely it can cause a mild fever and influenza-like symptoms and/or conjunctivitis in humans.
Polyomaviridae is a family of viruses whose natural hosts are primarily mammals and birds. [1] [2] As of 2024, there are eight recognized genera. [3]Fourteen species are known to infect humans, while others, such as Simian Virus 40, have been identified in humans to a lesser extent.
