Where we are: Since 2004 some 170 humans have been infected with bird flu, with about 90 fatalities, mostly in Asia, according to the World Health Organization.\n\nBackground: With the flu spreading around the world, the virus has turned up in birds in Asia and Europe, and, most recently, Africa. So far, bird flu has only been passed from birds either to other birds or, in isolated cases, to humans. However, if the flu mutates into a strain that can pass from human to human, people will have no immunity and the flu will probably pass rapidly from person to person, creating a pandemic. Flu vaccines can only be made to protect against a particular virus, and, since the virus has yet to be passed from human to human, no vaccine can be developed.\n\nIn Asia, many people live with ducks and chickens in their homes and in their yards. Health and veterinary officials worldwide recently announced that a key way to stop the spread of the disease is to improve farming practices, segregating poultry from humans, and culling birds that have been infected with the deadly virus.\n\nWhat's next? When asked for predictions as to the seriousness of the pandemic, should one occur, experts have based their projections on a similar pandemic that occurred in 1918-1919. Up to a billion people fell ill, and nearly 100 million died worldwide. Translating to today's figures, they project that some 30-60 percent of the world's population could be infected by the virus, and over 300 million people worldwide could die. In the meantime, good hygiene remains the best prevention: keep hands well-washed, and avoid contact with people who have been infected with the virus.

From your description I'd say it was run over. So no bird flu. \nBut it might be a good precaution if you just generally stayed away from all and sundry dead animals. Just to get in the habit. \nBy the way, so far people have only picked up bird flu from birds, not from any other animal despite the fact that other animals (e.g. cats) can get it. Don't worry too much.

it was called the "Spanish Flu"  And it was a couple of years earlier... It affected the whole world.. That is why The "Bird Flu' was such a HUGE concern...\n\nThe global mortality rate from the 1918/1919 pandemic is not known, but is estimated at 2.5 – 5% of the human population, with 20% of the world population suffering from the disease to some extent. Influenza may have killed as many as 25 million in its first 25 weeks; in contrast, AIDS killed 25 million in its first 25 years. Influenza spread across the world, killing more than 25 million in six months; some estimates put the total killed at over twice that number, possibly even 100 million.\n\nIn the U.S., about 28% of the population suffered, and 500,000 to 675,000 died. In Britain 200,000 died; in France more than 400,000. Entire villages perished in Alaska and southern Africa. In Australia an estimated 10,000 people died and in the Fiji Islands, 14% of the population died during only two weeks, and in Western Samoa 22%. An estimated 17 million died in India, about 5% of India's population at the time. In the Indian Army, almost 22% of troops who caught the disease died of it.\n\nWhile World War I didn't cause the flu, the close quarters and mass movement of troops quickened its spread. It has been speculated that the soldiers' immune systems were weakened by the stresses of combat and chemical attacks, increasing their susceptibility to the disease.

very concerned, think about chain reactions. lets say i have a infected chicken, and i skin it. i give the feathers to a pillow company and the rest to a processing company. lets say that a woman with three children buys the chicken, and she works at a school. think of all those people the workers and children pass by at work/school, and the people they love. that is serious.\n\nYes we should, unfortunately, we dont have antibodies for the avian flu. Yet.

After consulation with members of the health protection agency (UK), i disagree with the last guy to answer. The general consensus of opinion is that bird flu will mutate, and it is obly a matter of time. However, it may mutate and lose its virility; it may end up no more annoying than a cold. It may have even already mutated, but we just havent noticed it in the population...\n\nHow do i plan to prepare? the best advice is to take any flu jabs OFFERED, and have a few extra tin goods in the house, so you can stay inside longer than normal, but there is no need to panic buy.\n\nBird flu has currently got a death rate of 56%, which is very high for any disease, and avain flu's have a habit of mutating into a mammalian form, so we should be on our guard.

UPDATED The H5N1 strain of influenza - often referred to as bird flu - is first known to have jumped from chickens to humans\n\nin 1997. Since 2004 it has ripped through poultry and wild bird populations across Eurasia, and had a 53% mortality rate in the first 147 people it is known to have infected. Health authorities fear this strain, or its descendent, could cause a lethal new flu pandemic in people with the potential to kill billions.\n\nFlu has been a regular scourge of humanity for thousands of years. Flu viruses each possess a mere 10 genes encoded in RNA. All of the 16 known genetic subgroups originate in water birds, and especially in ducks. The virus is well adapted to their immune systems, and does not usually make them sick. This leaves the animals free to move around and spread the virus - just what it needs to persist.\n\nBut sometimes a bird flu virus jumps to an animal whose immune system it is not adapted to. In chickens - originally a forest bird and not a natural host - it causes a moderate disease but can readily mutate to a more severe, highly pathogenic strain. Just such a strain of H5N1 flu, named after its surface proteins, began rampaging through large chicken farms in east Asia sometime before 2003.\n\nThat was of concern because, in 1997, scientists found for the first time that H5 flu could infect humans. It was found in 18 people, six of whom died. All the poultry in Hong Kong were destroyed to stop the threat. But it continued to circulate, especially in China.\n\nThere were further human cases in China in 2003. Then in early 2004 Vietnam reported widespread poultry outbreaks and some human cases. After initial denials, Cambodia and Thailand admitted they had outbreaks too, followed by Indonesia, then China. That was immediately after China had denied a New Scientist report that scientists strongly suspected Chinese outbreaks.\n\nThe infection also reached Japan, Malaysia and South Korea, but mass culling stopped it spreading there. But outbreaks continued in China, Indonesia and Vietnam, where the virus persisted, most probably in ducks. In 2005, China and Indonesia reported their first human cases.\n\nEuropean invasion\nIn summer 2005 the virus swept across birds in Russia and Kazakhstan, reaching the Ukraine by January 2006. However, there were no reported human c ases outside East Asia until December 2005. Then, the virus suddenly appeared in poultry all over Turkey accompanied by the fastest upsurge in human cases yet seen.\n\nBut scientists insisted that the virus’s arrival in Europe did not pose a greater threat of a pandemic than its continued spread in Asia.\n\nAttempts to blame the rapid spread of the virus in the Far East on wild birds were discounted early on, so efforts to explain its spread across Eurasia in that way were greeted with suspicion. But in May 2005, thousands of geese died of H5N1 at Qinghai Lake in north-central China. The virus was very similar to isolated samples from southeast China, showing, despite official denials, that it originated there. But it had distinctive differences. This same strain then turned up in H5N1 isolates from poultry and wild birds across Russia, Turkey and Romania, suggesting that this time it probably was being carried by wild birds.\n\nMeanwhile east Asian H5N1 turned up in imported Taiwanese birds in quarantine in Britain. This, combined with a near-miss with infected eagles smuggled into Belgium, led to a European clamp-down on wild bird imports.\n\nThe virulent strain could to revert to a relatively harmless wild type in wild birds. However, while it is there, it could be carried to poultry far and wide. It has now reached Africa - where it is feared it could run riot. Wild birds are also implicated in its spread across Europe.\n\nYet governments resisted repeated UN calls for money to eradicate the poultry infection in poor countries. The World Bank renewed calls for such aid in early 2006, while all afflicted countries struggled to s

To be perfectly honest, im not sure why it has spread now. However it is likely to be due to the amount of H5N1 in the bird population slowly increasing. It has been around in china since 1997, and I guess now, people are more vigulant in looking for it.\n\nIt is entirely possible that the virus has undergone genetic drift, making it easier to pass between birds, enabling it to spread faster in the wild bird populaton.\n\nThe rapid spread is something to be concerned about since it will mean a greater chance of the H5N1 infecting a mammalian cell, at the same time as a mammalian flu. If this happens, genetic shift can take place, which could allow the H5N1 to spread between humans.\n\nThe wider it is spread, the less chance we have of controlling any outbreak....\n\nHope that goes someway to answering your question

Key Facts About Avian Influenza (Bird Flu) and Avian Influenza A (H5N1) Virus\nE-mail this page\nPrinter-friendly version\nWhat You Should Know About Avian Flu\nKey Facts\nInfections in Humans\nQuestions & Answers\nCurrent Situation\nThis fact sheet provides general information about avian influenza (bird flu) and information about one type of bird flu, called avian influenza A (H5N1), that has caused infections in birds in Asia and Europe and in humans in Asia. Also see Questions and Answers on the CDC website and Frequently Asked Questions (FAQs) on the World Health Organization (WHO) website.\n\nAvian Influenza (Bird Flu)\nAvian influenza in birds\nAvian influenza is an infection caused by avian (bird) influenza (flu) viruses. These influenza viruses occur naturally among birds. Wild birds worldwide carry the viruses in their intestines, but usually do not get sick from them. However, avian influenza is very contagious among birds and can make some domesticated birds, including chickens, ducks, and turkeys, very sick and kill them.\n\nInfected birds shed influenza virus in their saliva, nasal secretions, and feces. Susceptible birds become infected when they have contact with contaminated secretions or excretions or with surfaces that are contaminated with secretions or excretions from infected birds. Domesticated birds may become infected with avian influenza virus through direct contact with infected waterfowl or other infected poultry, or through contact with surfaces (such as dirt or cages) or materials (such as water or feed) that have been contaminated with the virus.\n\nInfection with avian influenza viruses in domestic poultry causes two main forms of disease that are distinguished by low and high extremes of virulence. The “low pathogenic” form may go undetected and usually causes only mild symptoms (such as ruffled feathers and a drop in egg production). However, the highly pathogenic form spreads more rapidly through flocks of poultry. This form may cause disease that affects multiple internal organs and has a mortality rate that can reach 90-100% often within 48 hours.\n\nHuman infection with avian influenza viruses\nThere are many different subtypes of type A influenza viruses. These subtypes differ because of changes in certain proteins on the surface of the influenza A virus (hemagglutinin [HA] and neuraminidase [NA] proteins). There are 16 known HA subtypes and 9 known NA subtypes of influenza A viruses. Many different combinations of HA and NA proteins are possible. Each combination represents a different subtype. All known subtypes of influenza A viruses can be found in birds.\n\nUsually, “avian influenza virus” refers to influenza A viruses found chiefly in birds, but infections with these viruses can occur in humans. The risk from avian influenza is generally low to most people, because the viruses do not usually infect humans. However, confirmed cases of human infection from several subtypes of avian influenza infection have been reported since 1997. Most cases of avian influenza infection in humans have resulted from contact with infected poultry (e.g., domesticated chicken, ducks, and turkeys) or surfaces contaminated with secretion/excretions from infected birds. The spread of avian influenza viruses from one ill person to another has been reported very rarely, and transmission has not been observed to continue beyond one person.\n\n“Human influenza virus” usually refers to those subtypes that spread widely among humans. There are only three known A subtypes of influenza viruses (H1N1, H1N2, and H3N2) currently circulating among humans. It is likely that some genetic parts of current human influenza A viruses came from birds originally. Influenza A viruses are constantly changing, and they might adapt over time to infect and spread among humans.\n\nDuring an outbreak of avian influenza among poultry, there is a possible risk to people who have contact with infected birds or surfaces that

Flu is caused by an adenovirus virus which is transmitted by human contact usually in the winter - its usually an epidemic between school and college students since a big group of them is usually found together in the same room and the virus can transmit more easily.\n\nCough & Fever are symptoms of the flu .. along with possible nausea, exhaustion, headache and nose congestion.

Relax.  The media in the US is making people crazy about bird flu.  The rest of the world isn't concerned. Turn off the tv.

Lots of things can. Flu can cause it. Taking some medicines such as some cholesterol drugs can do it. If this is a problem, ask a doctor.

Also, if u don't eat birds (if ur a vegetarian) u won't get the bird flu. Vegetarianism also has a lot of other benefits. The PETA and Vegan Outreach websites have a lot of info on that.

It is called the foot and mouth diseae which attackes cattle like pigs, cows, goats and so on. Looks like livestocks, including chickens that spread the bird flu are not to be taken for the time being. If you worry, take fish only or opt to be a vegeterian instead.Meantime, protection yourself by taking lots fruits becos they contain Vit.C and eating raw garlic or pills form of it.
