Bird flu is a general term for some strains of influenza (flu) that are

that are found in poultry and other birds. It is more properly called Avian Influenza. There are two strains of this kind of influenza virus are known to infect humans in very rare circumstances. H5N1 is one of the specific strains of bird flu that infects humans. H7N9 is the other and new strain just discovered in humans in Spring 2013.


Flu viruses are a group of RNA viruses categorized to the three main types of influenzaviruses found in humans and other animals. These are classified as Influenza Types A, B, and C. "Bird flu" refers to an illness caused by any of the many different strains of Type A flu viruses that are endemic in birds.

All known bird (or avian) flu viruses are Influenza A viruses. Inf

luenza A viruses have been isolated from many species, including humans, pigs, horses, marine mammals, and a wide range of domestic birds but because wildfowl and shorebirds are thought to form the main influenza virus reservoir in nature, infections resulting from Influenza A viruses are sometimes termed "bird flu."

The Influenza A virus genome consists of negative-stranded RNA, which codes for 11 proteins. These viruses are classified on the basis of two of these proteins which are expressed on the surface of the virion (virus particles); these are the hemagglutinn (HA) and neuraminidase (NA) glycoproteins.

Sixteen different HA and 9 NA subtypes have been isolated from viruses in wild birds and poultry throughout the world. These can be found in numerous protein combinations (for example: H2N2, H16N3, H5N1, H7N9). Mature HA proteins mediate binding of the virus particles to host cells.

Influenza viruses of subtypes H5 and H7 are highly pathogenic and contagious in birds and can cause outbreaks of bird flu in wild fowl and poultry. People have been known to contract H5N1 bird flu by contamination through bird handling and roughly 50% of those have died. It does not usually transmit from human to human. Since 2003 360 people have died worldwide of H5N1 bird flu and tens of millions of birds have died.

H5N1 is but one subtype of "bird flu" which happens to be especially contagious and pathogenic. It is rare in humans.

At Easter time in 2013, another and more rare strain (H7N9) was found to be the organism that caused two deaths in Shanghai, China. These are the first two known human infections and deaths by avian flu viruses other than H5N1. A third victim is critically ill, also in China. None gave the flu to the others and no close contacts of any of the three have been infected. Studies are rapidly getting underway to learn more about the new strain.

What is the difference between the flu and H5N1?

H5N1 influenza virus is an avian flu, it is often called bird flu and is more specific than "the flu". Usually when people refer to the flu they do not specify (and most often don't know) which strain of the flu it is, they use "flu" (influenza) to refer to viral respiratory infections in a more general way.So, H5N1 is a flu, an influenza virus, but all strains and types of flu are not H5N1. For example, another subtype of influenza virus is the now well-known 2009 pandemic swine flu, which is identified as Human Influenza virus Type A-H1N1-09. There are other strains that also have the protein configuration H1N1 as the subtype (this is how they are named), and there are many strains for each of them. H1N1 viruses are the viruses that have been involved in pandemics and are commonly included in the seasonal flu vaccines.There is no real difference in treatment for the different influenza viruses in humans, therefore, it most often is not necessary in medicine to do the lab testing to identify the specific virus involved.


What is the name of the virus that causes influenza?

It is simply known as the flu virus generally, but each individual strand has its own name, like H1N1 is the swine flu, and H5N1 is the bird flu.

Is there a vaccine or cure or treatment for bird flu?

Currently there is no cure for the bird flu (H5N1), but the symptoms are treated. There has been a vaccine developed for the US, but it is stockpiled by the government in case there is a pandemic, so it is not available as a preventive vaccine yet.


How has each person with bird flu contracted the virus?

People catch bird flu by close contact with birds or bird droppings. This is just the flu that infects birds. The bird flu that people often call the bird flu is not the same. That one is passed from person to person.Some people have caught H5N1 from cleaning or plucking infected birds. In China, there have been reports of infection via inhalation of aerosolized materials in live bird markets. And some infections have occurred in people who handle fighting cocks.There have been a few cases where one infected person caught the bird flu virus from another person -- but only after close personal contact. So far, there has been no sustained human-to-human spread of H5N1.

What is the importance of the hygiene and sanitation for broiler chicken?

hygiene and sanitation is very important for broiler chicken as they are very susceptible to diseases. wild bird carry H5N1 virus(bird flu) and broiler are vulnerable to such virus. so during winters and the peroid when migration of birds take place...special care is taken in chicken farms to avoid such dangerous incident of H5N1 flu. H5N1 virus is present in the blood, saliva and other secretions of bird(including excreta). This virus can be spread by footwear also. any contact with the secretions of bird will result in such a disaster. so sanitation is very important.


Is Avian Flu the only disease caused by the H5N1 virus?
