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.
H5 N2 is a subtype of the species Influenzavirus A (avian influenza virus or bird flu virus). The subtype infects a wide variety of birds, including chickens, ducks, turkeys, falcons, and ostriches. Affected birds usually do not appear ill, and the disease is often mild as avian influenza viral subtypes go.
Influenza A virus subtype H5N1 (A/H5N1) is a subtype of the influenza A virus, which causes the disease avian influenza (often referred to as "bird flu"). It is enzootic (maintained in the population) in many bird populations, and also panzootic (affecting animals of many species over a wide area). [1]
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 ...
Test results indicated that these animals were likely ill from H5N1 avian flu, which was first seen in wild birds in the United States in 2015," the county health department said on Dec. 11.
Since it was first discovered in birds in 1996, H5N1 has shown itself to be a Swiss Army Knife of a virus, evolving the necessary tools to break into the cells of a growing list of species.
H10N3 has been isolated across a wide geographic distribution, including in species such as domestic poultry (chickens), [2] ducks, [3] [4] other waterfowl, and terrestrial birds. [5] In animals, the viruses display a complex pathology, with complex reassortments and mutations contributing to pathobiology patterns in chickens, ducks and mice ...
The Wildlife World Zoo in Litchfield, Ariz., had six animals test positive for avian flu, with five dying of the infection, the Maricopa County Public Health Department said on Wednesday, Dec. 11.
