Avian influenza refers to disease in birds caused by infection with avian (bird) influenza (flu) Type A viruses. (cdc.gov)
Avian influenza A viruses have been isolated from more than 100 different species of wild birds around the world. (cdc.gov)
These viruses occur naturally among wild aquatic birds worldwide and can infect domestic poultry and other bird and animal species. (cdc.gov)
Wild aquatic birds, especially dabbling ducks, are considered reservoirs (hosts) for avian influenza A viruses. (cdc.gov)
Wild aquatic birds can be infected with avian influenza A viruses in their intestines and respiratory tract, but some species, such as ducks, may not get sick. (cdc.gov)
However, avian influenza A viruses are very contagious among birds, and some of these viruses can sicken and even kill certain domesticated bird species, including chickens, ducks and turkeys. (cdc.gov)
Infected birds can shed avian influenza A viruses in their saliva, nasal secretions, and feces. (cdc.gov)
Avian influenza A viruses are classified into the following two categories: low pathogenicity avian influenza (LPAI) A viruses, and highly pathogenic avian influenza (HPAI) A viruses. (cdc.gov)
Low pathogenic avian influenza viruses cause either no signs of disease or mild disease in chickens/poultry (such as ruffled feathers and a drop in egg production). (cdc.gov)
Most avian influenza A viruses are low pathogenic and cause few signs of disease in infected wild birds. (cdc.gov)

Sanmenxia Clade 2.3.2.1c-like H5N1 viruses possess the closest genetic identity to A/Alberta/01/2014 (H5N1), which recently caused a fatal respiratory infection in Canada with signs of meningoencephalitis, a highly unusual symptom with influenza infections in humans. (nature.com)
Due to the geographical location of Sanmenxia, these novel H5N1 viruses also have the potential to be imported to other regions through the migration of wild birds, similar to the H5N1 outbreak amongst migratory birds in Qinghai Lake during 2005. (nature.com)
The Qinghai-like Clade 2.2 virus was found to possess a high genetic relationship with viruses isolated from other countries on the migratory flyway of wild birds 4 , suggesting that the migration of wild birds played an important role in circulating H5N1 HPAIV viruses between the different avian populations.

Avian influenza is a viral disease caused by various strains of avian influenza viruses that can be classified as low pathogenic avian influenza (LPAI) or highly pathogenic avian influenza (HPAI). (usgs.gov)
The USGS National Wildlife Health Center (NWHC) in collaboration with multiple partners conducts research into the ecology of avian influenza virus and surveillance for highly pathogenic avian influenza (HPAI) viruses leading to several significant findings towards early detection and response to HPAI. (usgs.gov)
Wild birds, in particular certain species of waterfowl and shorebirds, are considered to be the natural reservoirs for avian influenza viruses. (usgs.gov)
In domestic birds, however, some AI viruses can be more pathogenic and mutation or recombination of a virus acquired from wild birds can increase disease potential. (usgs.gov)
Avian influenza viruses (AIV) are classified by a combination of two groups of proteins found on the surface of the virus: hemagglutinin proteins (H), of which there are 18 (H1-H18), and neuraminidase proteins (N), of which there are 11 (N1-N11). (usgs.gov)
Additional information on avian influenza viruses are available in the Field Manual of Wildlife Diseases . (usgs.gov)
It has been thought that Eurasian strains of avian influenza viruses enter the United States through the Pacific Flyway (Alaska to Baja California) and that this route is the most likely avenue for emerging Eurasian AIV strains to enter North America. (usgs.gov)
However, AIV also frequently infects domestic poultry and wild ducks in Europe and Africa and migrating wild birds that use the east Atlantic flyway may also risk introducing Eurasian strain viruses to North America via this route. (usgs.gov)
The USGS National Wildlife Health Center, in collaboration with the National Institutes of Health Centers of Excellence for Influenza Research and Surveillance (CEIRS), the University of Iceland, and other partners, has explored the ecology and movement of AI viruses in the North Atlantic region since 2010.

This research has demonstrated the importance of the migratory bird flyways in this region to the intercontinental movement of viruses between Europe and North America. (usgs.gov)
AI viruses from both continents, as well as recombinations of both strains, were isolated in Iceland, sometimes from within a single flock of birds, showing that this region is a hotspot of virus movement and genetic reassortment. (usgs.gov)
Highly pathogenic AI viruses have been frequently found in wild and domestic European birds, significantly in 2006, and annually since then. (usgs.gov)
Avian influenza viruses have been around for a very long time, but the Highly Pathogenic Avian Influenza (HPAI) virus strain (H5N1, clade 2.3.4.4b) that has been circulating in birds across much of the globe since 2021 has been the most long-lasting, widespread and severe on record.

however, because other bird flu viruses have infected people, it is possible that human infections with these viruses could occur. (cdc.gov)
Bird flu viruses can infect people when enough virus gets into a person's eyes, nose, or mouth, or is inhaled. (cdc.gov)
Avian influenza viruses (AIV) have been frequently detected in live bird markets (LBMs) around the world, primarily in urban areas , and have the ability to spillover to other species, including humans . (bvsalud.org)
On rare occasions, these bird viruses can cross over and infect other species, including cats, pigs and humans and can be a potential cause of pandemics. (who.int)

Avian influenza virus (AIV) gained a high profile after the unprecedented bird-to-human transmission of highly pathogenic AIV (HPAIV) subtype H5N1 in 1997. (cdc.gov)
Originating in Asia, HPAIV (H5N1) subsequently caused widespread deaths among wild and domestic birds in Southeast Asia and westward throughout Europe and Africa in 2005 and 2006. (cdc.gov)
Although the role of wild birds in HPAIV maintenance remains controversial ( 8 ), the magnitude of the subtype H5N1 epidemics increased the demand for early recognition of potential threats to humans and poultry and an understanding of the natural history of AIV in wild birds. (cdc.gov)
