Also known as the bird flu, avian influenza is a disease that once infected only
birds. However, the new avian flu virus that has emerged in Asia can be
transferred from fowl to humans and has acquired the ability to infect humans
with deadly results. As a result, the World Health Organization and the Centers
for Disease Control and Prevention are closely monitoring what could be the next
deadly flu pandemic. If this virus mutates further, it may acquire the ability
to be transmitted from person to person.
It is a very real threat and every government on every level has been preparing for it for years. Avian influenza, or bird flu, is a major concern for public health authorities and is an increasing threat to public health. With the bird flu war being fought and starting to fail, we really can't win a Biological War, you can never be too careful especially if you own ducks, chickens, birds, poultry farms.
The highly pathogenic influenza A virus subtype H5N1 virus is an emerging avian influenza virus that has been causing global concern as a potential pandemic threat. It is often referred to simply as "bird flu" or "avian influenza" even though it is only one subtype of avian influenza causing virus.
H5N1 has killed millions of poultry in a growing number of countries throughout Asia, Europe and Africa. Health experts are concerned that the co-existence of human flu viruses and avian flu viruses (especially H5N1) will provide an opportunity for genetic material to be exchanged between species-specific viruses, possibly creating a new virulent influenza strain that is easily transmissible and lethal to humans.
Since the first H5N1 outbreak occurred in 1997, there has been an increasing number of HPAI H5N1 bird-to-human transmissions leading to clinically severe and fatal human infections. However, because there is a significant species barrier that exists between birds and humans, the virus does not easily cross over to humans, though some cases of infection are being researched to discern whether human to human transmission is occurring. More research is necessary to understand the pathogenesis and epidemiology of the H5N1 virus in humans. Exposure routes and other disease transmission characteristics such as genetic and immunological factors, that may increase the likelihood of infection, are not clearly understood.

I'm not really familiar with t his kinds of flu unil I saw it on the news. It is a warning for us to be always safe and keep ourselves healthy and protected against this kind of diseases.
