H5N6 is a subtype of the species Influenza A virus (sometimes called bird flu virus). Infected birds shed the virus in their saliva, mucus, and feces. The virus was first detected in poultry in 2013, since then spreading among wild bird populations and poultry around the world.
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, or bird flu, is a broad term that refers to several types of influenza that normally infect birds. The bird flu that’s been making news in the United States is a virus called H5N1.
Bird flu cases are mainly restricted to commercial poultry and cattle, data shows. Eggs, meat, cheese and milk that are sold commercially are safe to eat , according to Harvard Medical School.
This colorized electron microscope image provided by the National Institute of Allergy and Infectious Diseases in 2024 shows avian influenza A virus (bird flu) particles, red-yellow, grown in ...
Although a wide variety of bird species have been shown to contract and spread Influenza A virus subtype H5N1, from waterfowl to poultry and birds of prey, mammalian infections have been of particular interest to researchers due to their potential to develop mutations that increase the risk of mammal-to-mammal spread and transmission to and among humans.
While other H5N1 influenza strains are known, they are significantly different on a genetic level from a highly pathogenic, emergent strain of H5N1, which was able to achieve hitherto unprecedented global spread in 2008. [1] The H5N1 strain is a fast-mutating, highly pathogenic avian influenza virus (HPAI) found in multiple bird species. It is ...
What is the bird flu? Bird flu, also known as highly pathogenic avian influenza (HPAI), is caused by a virus that can result in serious illness and death in birds and mammals.
