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.
Bird flu is a scary illness with a high mortality rate. But so far, infections in the U.S. have been relatively mild—until now. A patient in Louisiana has been hospitalized with a severe case of ...
What we think of as the seasonal flu in humans is caused by types A and B. Bird flu falls under the umbrella of influenza A viruses. The strain currently spreading in the U.S. is H5N1, an HPAI ...
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]
[2] [12] In November 2013, the U.S. Food and Drug Administration (FDA) approved an experimental H5N1 bird flu vaccine to be held in stockpiles. [22] [23] In a clinical trial including 3,400 adults, 91% of people age 18–64 and 74% of people age 65 or older formed an immune response sufficient to provide protection. Reported adverse effects ...
Bird flu in humans may look similar to a regular flu or upper respiratory infection, said Babcock, or a person may have no obvious symptoms. It can also lead to pneumonia, respiratory failure and ...
Transmission and infection of H5N1 from infected avian sources to humans has been a concern since the first documented case of human infection in 1997, [1] due to the global spread of H5N1 that constitutes a pandemic threat. Infected birds pass on H5N1 through their saliva, nasal secretions, and feces. Other birds may pick up the virus through ...
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.
