Bird Flu

The recent growth of bird flu cases popping up around the globe has triggered a world wide concern to prevent the spreading of this lethal disease.

Firstly, avian flu or bird flu caused by the H5N1 virus is a very common affliction with wild birds. Although they are only carriers without being affected by the infection, the disease is deadly for domestic poultry and humans.

Furthermore, the increased number of people affected by avian flu and its high mortality rate prove that the H5N1 virus has the power to mutate and redevelop its structure. The virus can be detected in the saliva and nasal secretions of birds. The possibility of new strains being developed is more likely to happen in under-privileged communities where people live in close quarters with poultry. For example, sharing the same water between various types of domesticated animals can determine animal-to-animal transmission and even more drastically animal-to-human transmission.

Additionaly, even the common flu virus manifests a permanent antigenic shift. For this reason, the vaccines must be constantly updated to be able to fight-back the newest strains of the virus. Until now there have been detected three types of influenza viruses: A, B and C, the former being the most dangerous to humans.

Moreover, immunity deficiency against avian flu can generate a world wide pandemic. Even more the virus does not respond to Amantadine (drugs used to treat flu). Among the manifestations of the infection are: fever, sore throat, muscle aches, headaches, lethargy, conjunctivitis (eye infections), chest pains and breathing problems. Death occurs because of respiratory illnesses in no more than weeks after contacting the infection. The cases of avian flu affecting humans have provoked the killing of millions of domestic birds in South-East Asia in a desperate try to prevent the further spread of the virus.

All in all, the possibility of the H5N1 virus to cause a flu pandemic has put scientists on a tight race to protect human existence by creating an efficient vaccine against this dreadful disease.

Scientists finally create an effective vaccine against Bird flu virus

So far, the public health authorities have been in a continuous alert due to the presence of H5N1, the bird flu virus which affected Asia and infected about 100 humans in the past 18 months, half of the victims not surviving the virus attack. Scientists worry about a possible global pandemic, and so they have been trying to develop an effective vaccine against H5N1. Until now millions of birds were slaughtered in Asia in the attempt of stopping the virus from transmitting itself to animals and humans.

After a long wait, yesterday, a federal health spokesman said that the scientists have finally created an effective vaccine against a strain of the flu virus that is considered to be a possible spark for the beginning of a global pandemic.

The vaccine has been tested on 133 volunteers within a study conducted by US universities, and has proved to be efficient, providing a powerful weapon against the flu virus.

The study has been conducted at the University of Maryland at Baltimore, the University of Rochester in New York and the University of California at Los Angeles.

The conclusions of the study were that two doses of the vaccine are enough to produce the right immunization to neutralize the virus.

Also, a British company is working to produce an effective bird flu vaccine.

The director of the National Institute of Allergy and Infectious Diseases, Anthony S. Fauci declared to be very enthusiastic about the new vaccine and its immunizing properties, also declaring that he considers the tests to be a key step in the world's attempt to stop a possible global pandemic.

Another scientist, Michael T. Osterholm of the University of Minnesota was very relieved when hearing about the success registered by the new vaccine when tested, and declare that he was worried about the fact that two doses of the vaccine might not have been working, that constituting a real problem for the researchers.

More testing will be needed before the vaccine will be ready to be mass produced, and also a method of distributing large quantities will have to be designed.

Scientists are positive that in case of a global pandemic a lot of people will be left unvaccinated due to the existent lacks in the health system, because it is not easy to produce and distribute the vaccine effectively in a short time.

How's and Why's Of Bird Flu Attack

Bird flu attacked many Nations. How and why it actually happened no one knows! The speed with which it spread all over the world was a mystery and confusion confounded. With its universal ?influence? it crippled many, without the distinction of race, color and nationality.

This bird-flu has the capacity to make such a big kill, the casualties of World War I and II put together will be a kindergarten stuff before the possible number of deaths due to bird flu.

With the drugs, antibiotics and vaccines developed so far to combat bird flu having proved ineffective, the alternative is now to search whether the nature has in store some natural herbs. If they are there, how to make their effective use is another matter for the researchers and scientists.

Can the Governments do something for the people to provide a protective cover in such emergent situations? What could do they do during Hurricane Katrina? At the time of Tsunami? That was just a small fraction of the world that was affected. What if the whole world were to be engulfed in bird flu?

Many Nations are at present attacked by bird flu but the damage is limited. As of now, the disease is not transmitted from human to human. Millions of birds and fowl are culled and destroyed in a desperate effort to contain it. But the virus of bird flu is evolving and changing. Sooner or later it will not spare the human beings, why should it? And why should the Nature come to the rescue? Have you been kind to the nature? We continue to exploit it to the hilt! Less said the better about the treatment human beings mete out to the animal kingdom!

The answer to the specific question-how did bird flu happen, I know will draw blank responses from you. I don't blame you. Human history, for that matter human health history is full off such ambiguities. But the projections about the possible consequence of a mass attack of bird-flu will be catastrophic! None has the solution. Nature has varied methods of population control. And when it uses those methods, it uses them ruthlessly.

It is indeed a no-win win situation. The question would no more be how did bird flu happen, the question then would be why did bird flu happen??
