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.
“For example, if a human gets infected with a bird flu and also carries a human influenza A virus, these two viruses can exchange genetic material. This is known as genetic shift ,” Michael says.
Doctors urge people who are experiencing respiratory problems to see a medical professional who can check their symptoms and test to determine what their illness is.
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.
The virus was first detected in poultry in 2013, since then spreading among wild bird populations and poultry around the world. Humans can be infected through unprotected contact with infected birds or contaminated surfaces. The virus transmits by getting into a person's eyes, nose, mouth, and through inhalation. Human infections are rare.
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.
Bird flu can also cause respiratory and classic flu-like symptoms, including cough, runny nose, fever, sore throat, body aches, headaches, fatigue, shortness of breath, and pneumonia, the CDC says ...
H5N1 influenza virus is a type of influenza A virus which mostly infects birds. H5N1 flu is a concern because its global spread may constitute a pandemic threat. The yardstick for human mortality from H5N1 is the case-fatality rate (CFR); the ratio of the number of confirmed human deaths resulting from infection of H5N1 to the number of those confirmed cases of infection with the virus.
