Wrath of God behind Israel bird flu, says rabbi
JERUSALEM, March 21 (Reuters) - An outbreak of deadly bird flu in Israel is God's punishment for calls in election ads to legalise gay marriages, according to Rabbi David Basri, a prominent sage preaching Kabbalah or Jewish mysticism. "The Bible says that God punishes depravity first through plagues against animals and then in people," Basri said in a religious edict quoted by his son. Basri said he hoped the deaths of hundreds of thousands of turkeys and chickens would help atone for what he called the sins of left-wing Israeli political parties, the son, Rabbi Yitzhak Basri, told Reuters, a week before a national election. The bird flu outbreak stemmed from far-left political parties "strengthening and encouraging homosexuality," Rabbi Basri's son quoted him as saying. One of the parties aired an election commercial depicting two brides kissing. Some campaign advertisements also called for homosexual marriages to be legalised in Israel. Basri is a prominent Kabbalist and author of commentaries on the Zohar, the main Kabbalah mystical text. 211227 Mrz 06 ENDOFMSG #102Posted 2006-03-21 18:45:16
Malaysia fears bird flu may spread nationwide: junior minister
ATTENTION - ADDS PM's quotes, nationwide testing /// KUALA LUMPUR, March 21, 2006 (AFP) - A Malaysian deputy minister warned Tuesday that the deadly bird flu virus may spread nationwide after two more outbreaks were reported in a northern state. "There is always the possibility (of this)," Deputy Agriculture Minister Mah Siew Keong told reporters. "We hope there will be not be many more new cases. We are taking all the steps. The ministry is concerned at the outbreaks." An official in the northern state of Perak reported two new outbreaks of the H5N1 strain there, at Changkat Legong and at Titi Gantung, which is 60 kilometres (37 miles) west of Changkat Legong. But no birds have died of the disease in the two areas, Perak agriculture committee chairman Mohamad Radzi Manan was quoted as saying by Bernama news agency. Mohamad Radzi said veterinary officials have began to slaughter poultry in the two areas and expect to kill some 3,000 birds. Separately, Prime Minister Abdullah Ahmad Badawi told reporters the outbreak was under control and that he had met with Agriculture Minister Muhyiddin Yassin and Health Minister Chua Soi Lek following the latest outbreaks, one of which is not far from his own constituency. "Both of them are managing the situation very well," he said adding that Malaysia was always in a state of readiness to deal with new outbreaks. Muhyiddin said authorities would start taking samples from fowls nationwide for H5N1 after the latest outbreaks. "We have instructed all state veterinary directors to carry out comprehensive samplings. Previously, we tested only the affected areas but now each state must do it," he was quoted as saying by the Bernama news agency. He said a comprehensive plan would be drawn up to deal with the possibility of a nationwide outbreak. In the first outbreak in Malaysia in more than a year, H5N1 was detected last month in 40 free-range chickens in four villages in Gombak near Kuala Lumpur. Last Thursday Malaysia announced outbreaks of H5N1 in an eco-park and at Changkat Tualang, which is within five kilometres of Changkat Legong. On Monday an outbreak of H5N1 was announced in Permatang Bagak village in Penang state bordering Perak. "Unfortunately, yesterday the bird flu was confirmed in mainland Penang. So it means since last month's outbreak in Gombak, it has spread to Perak and now it is confirmed in Penang," Mah said, adding that authorities have yet to confirm how the birds were infected. He said neighbouring Singapore had banned poultry imports from Perak, which is one of Malaysia's biggest exporters of poultry. Officials have slaughtered tens of thousands of birds at the site of outbreaks. No human cases of bird flu have been reported so far in the country. About 100 people have died from bird flu since 2003, most of them in Asia. ey-hh/mtp AFP 211045 GMT MAR 06 #103Posted 2006-03-21 18:48:29
Humans test negative in India's bird flu-hit stat
MUMBAI, March 21 (Reuters) - All four people quarantined in western India for flu-like symptoms have tested negative for bird flu, officials said on Tuesday, as fears of human infection from avian influenza eased in the world's second most populous nation. The four people, including a doctor and a five-year-old girl, were from Jalgaon district in Maharashtra state where India's second outbreak of the H5N1 strain of bird flu in poultry was reported last week. Jalgaon is next door to Nandurbar district where the first outbreak occurred last month. "The test results of the four under observation are negative, but they are being given Tamiflu as a precaution," T.P. Doke, Maharashtra's health director, said, referring to the drug used to fight bird flu in humans. So far, India has reported no human infections from bird flu. Officials say another 95 human blood samples from Jalgaon had been sent for testing, but termed the tests a matter of "academic interest". More than 90,000 birds have been culled in Jalgaon and authorities were concentrating their efforts on cleaning up four villages spread over 1,100 square km (425 square miles) in the district where backyard poultry was found infected with bird flu. "We are disinfecting homes and cleaning up backyards and the drainage systems," Bijay Kumar, the state's animal husbandry commissioner, said #104Posted 2006-03-21 18:50:58
Why is Europe so neurotic about bird flu?
by Isabel Parenthoen PARIS, March 21, 2006 (AFP) - Bird flu has come to Europe and, if the newspapers are any guide, many Europeans are running around like, well, headless chickens. In some countries, sales of poultry have hit the floor. Panicky pet-owners have dumped their dog or cat, fearing that felines and canines can somehow pass on an avian virus. And police are fed up with fielding calls from terrified people who have spotted a dead pigeon or a stork building its nest -- and, in one case in eastern France, an owl that made a menacing hoot. The daftness gives the lie to a continent that prides itself on having the world's richest history in science, the most educated population and a communications system that is second to none. But there is no surprise among historians and food experts, who say this irrationality has deep roots. From the 14th-century plague known as the Black Death to cholera, typhoid and killer influenza, Europe has experienced waves of deadly pandemics that, like bird flu, came from abroad, they say. And, over the past 20 years, confidence in food safety and government reassurance has been badly undermined by a series of scares. "We mistrust the authorities and their utterances," says French historian Madeleine Ferrieres. Antoine Flahault, who runs a French doctors' watchdog group called Sentinels for Disease Surveillance, agrees. "There is a certain logic which says you're better off not eating chicken, when you think about all the past lies and present confusion," he said. "When you are being told that there is zero risk, you remain on your guard, he said. The source for much of Europe's edginess was the April 1986 Chernobyl disaster. The stricken Soviet nuclear reactor spewed radioactive dust over swathes of Europe and spurred the rise of the green movement, which feeds on worries about food and environmental safety. In France, Chernobyl is recalled for the government's blithe assurance that no contamination had fallen on French soil. As wags suggested, this meant the cloud had obediently stopped at the national border. Then along came bovine spongeiform encephalopathy (BSE), which dealt a blow to Britain's beef industry that endures to this day. Britons today recall the moment in 1990, at the height of the scare, when the then agriculture minister, John Gummer, thrust a fairground beefburger into his child's mouth to prove that the meat was safe. Other episodes have been dioxin-tainted chicken and worries about US hormone-treated beef and genetically-modified crops. But on other continents, these opinion-shaping events either have not happened, nor have they been elevated to public consciousness by a powerful green movement. A contributing factor has been big changes in European eating habits, thanks to better hygiene and just-in-time supermarket delivery. In Europe "we have no longer know how to deal with suspicious foods," noted Ferrieres. In the past, she said, meat in Europe was boiled or stewed for a long time, both to tenderise it and kill bugs, but this folk wisdom has disappeared in favour of lightly cooked flesh demanded by modern recipes. Fanning the worries has been the emergence of terrifying new diseases that the authorities in Europe, as elsewhere, have so often fumbled. They include AIDS, in which for a while HIV-contaminated blood was allowed to enter blood banks, and Severe Acute Respiratory Syndrome (SARS). Rene Favier, a historian who writes on human responses to catastrophes, said the present alarm has an ironic tinge: People mistrust their government yet at the same time turn to it for help. "The risk is that governments are fearful of looking inactive so they launch big public-awareness campaigns to inform and reassure. This turns out to be counter-productive because it ends up up boosting people's worries," said Favier. ih-ri/ns/wdb AFP 210844 GMT MAR 06 #105Posted 2006-03-21 18:52:56
Nigeria's bird flu woes reveal poor country weaknesses to
deadly virus LAGOS, Nigeria (AP) _ The five weeks since a deadly bird flu virus was first detected in Nigeria provide a troubling illustration of what can happen when H5N1 hits an undeveloped country with a weak and often corrupt political system and two few resources devoted to health. Officials have been overwhelmed, responding too late and with too little as the disease spread quickly across Africa's most populous country and then on to its neighbors. Each week seems to bring more questions than answers _ How far has it already spread? Have humans been infected? International health officials fear the H5N1 strain will evolve into a virus that can be transmitted easily between people and become a pandemic. H5N1's spread to places like Nigeria, where monitoring is difficult, has been particularly worrying. Nigeria has yet to deploy medical teams equipped to take blood samples and systematically determine whether H5N1 has infected humans living near farms where the virus has been found in birds. 211011 mar 06GMT #106Posted 2006-03-21 18:56:14
France confirms new case of deadly bird flu strain in wild
duck PARIS (AP) _ A new case of the deadly H5N1 strain of bird flu has been found in a wild duck in a part of southeastern France already hit by the disease, the Agriculture Ministry said Tuesday. The duck was found dead on March 15 in the town of Divonne-les-Bains, near the Swiss border, in the Ain region that has already taken broad measures to prevent the spread of avian flu. The discovery, which prompted authorities to set up a security zone, was in the area where another H5N1 case was found late last month in another wild duck, the ministry said in a statement. At least 32 wild birds have been found in France with the flu. France also detected the lethal H5N1 flu last month on a turkey farm, the first commercial poultry in the European Union hit by the virus. Last week, as fears of the virus were subsiding, the state administrator for the Ain region announced that some poultry could go on sale again after a temporary ban following the first cases of the bird flu. 211049 mar 06GMT #107Posted 2006-03-21 19:00:53
Vietnam successfully synthesizes key ingredient for bird
flu drug HANOI, Vietnam (AP) _ Vietnamese scientists have successfully synthesized the main ingredient for the antiviral drug Tamiflu, which the country hopes to mass produce in the next two years, an official said Tuesday. Tran Van Sung, director of the Chemistry Institute said his agency, which has been working on the project for more than five months, has synthesized 2.5 grams of oseltavimir phosphate from anise. Sung said the Ministry of Science and Technology is expected to provide the institute with funds for more research on the manufacturing process. Sung said his project is separate from an agreement reached between Vietnam and Swiss drugmaker Roche last year, where Roche agreed to provide the country with the raw drug materials so that it could be put in capsule form in the communist country. 211046 mar 06GMT #108Posted 2006-03-21 19:27:08

Get vaccine or face mass bird culls -UK farmers
By Elizabeth Piper LONDON, March 21 (Reuters) - Britain's organic farmers urged the government on Tuesday to prepare stocks of vaccines to protect free-range chickens from bird flu, saying no one could stomach the mass culls seen during the foot-and-mouth outbreak. They praised the government for showing "more flexibility" about using vaccination for controlling any outbreak of the deadly H5N1 virus than it did in 2001 against foot and mouth, but said an expanded vaccination policy should be launched now. "There is nothing left in the kill, kill, kill armoury used to fight foot-and-mouth," a spokesman for organic campaign group the Soil Association said. "Government has already got some vaccine stockpiled mainly for exotic birds and those in zoos. That should be extended." Organic poultry farmers say vaccination is the only way to protect their growing market, where production has increased by 35 percent over the past year. By bringing poultry indoors for more than three months to escape infection, producers would lose their free-range status. "Securing the long-term future of sustainable, welfare-friendly systems is essential if we are to build up over the longer-term livestock which are...resistant to the seemingly endless cycle of diseases that challenge our farming industry," Patrick Holden, the association's director, said. The Netherlands, France and Russia have launched vaccination drives to fight bird flu, which has spread from Asia to the Middle East, Africa and Europe. It has killed more than 90 people and millions of birds. But many Dutch farmers have chosen to wait, fearful that vaccinated poultry might turn off consumers, and in France the programme has been limited to a southwest region and to geese and ducks. Russia is vaccinating domestic fowl. Britain's government has said it would keep an open mind on using vaccination -- which some say would reduce the spread of the H5N1 virus if it hit Britain -- but officials and advisers say as yet there is no vaccination that is efficient. They say vaccination would take too long to administer and could spread the disease by masking its symptoms. "Our position hasn't changed. We are keeping emergency vaccination under consideration," a spokesman for the UK Department for Environment, Food and Rural Affairs said. The government's chief scientific adviser, David King, said for the time being his advice would also be to hold off. "My advice is...not to use the current vaccine except to protect zoo birds that are caged and maintained in such a way that they can be carefully observed," he told Reuters. "If you use the current vaccine, you are faced with one which has not got a high efficiency of operation. It is highly likely that vaccinated birds would become ill and would shed the virus so that they can spread the virus to other birds." REUTERS 211427 Mrz 06 ENDOFMSG #110Posted 2006-03-21 21:10:52
Romania detects H5 bird flu in poultry near Bucharest
BUCHAREST, Romania (AP) _ Several chickens in a village located just a few kilometers from the Romanian capital have tested positive for an H5 subtype of bird flu, the Agriculture Ministry said Tuesday. Further tests were underway in Bucharest to confirm the diagnosis, which was made by a mobile laboratory in the Pruni village, and determine the strain of the virus. If the outbreak is confirmed, the village will be placed under a strict quarantine, health officials have said. The virus, which is believed to be the deadly H5N1 strain, was detected this month in 12 villages near the Black Sea. Health authorities were discussing Tuesday a set of measures to be taken to contain the virus, the Agriculture Ministry said. Experts fear that the virus could infect pet birds and poultry on the edges of Bucharest, a crowded city of 2.3 million where quarantine measures would be difficult to enforce. Romania reported its first cases of H5N1 in domestic fowl in October in its eastern Danube Delta region, which is transited by hundreds of thousands of migratory birds. No human cases have been reported in the country. 211240 mar 06GMT #111Posted 2006-03-21 21:18:06
US increases bird flu tests on wild birds
WASHINGTON, March 21, 2006 (AFP) - The US government has decided to sharply increase testing of wild birds for the deadly H5N1 strain of bird flu in the hope of quickly detecting its arrival and preventing an epizootic. As the disease spreads in Asia, Europe and Africa, health authorities in Washington calculate that bird flu could reach US shores this year or by the beginning of 2007, most likely through birds migrating from Asia to North America by way of Alaska. "We do not know for sure what role wild migratory birds play in the movement of this virus, but the potential exists for them to carry this virus to North America, and we have a responsibility to prepare for that possibility," said Secretary of the Interior Gale Norton when she unveiled Monday an Interagency Strategic Plan for the early detection of H5N1. "Working closely with our state, local and federal partners, we can detect and respond to disease events involving wild birds and screen birds for highly pathogenic H5N1 virus," Norton said. "These actions will help us provide an early warning to the agriculture, public health and wildlife communities if the virus is detected in migratory birds," she told a news conference, flanked by the secretaries of agriculture and health, Mike Johanns and Mike Leavitt. After bird flu was first detected in Southeast Asia in 1997, US experts have tested more than 12,000 birds in the Alaska flyway since 2000, and almost 4,000 birds in the Atlantic flyway. All those birds tested negatively for H5N1, the experts said. Under the new strategic plan, the US Department of Agriculture and its cooperators plan to collect between 75,000 and 100,000 samples from live and dead wild birds. They also plan to collect samples of water or feces from high-risk waterfowl habitats around the United States. Authorities say they will test birds shot by hunters and live fowl on farms and birds sold on the market. If an infection is detected, health authorities said they will place the affected area under immediate quarantine and destroy all birds potentially infected with the H5N1 virus. The primary goal is to prevent all contact between the infected birds and people living in the area, as well as limiting the devastating economic damage it could inflict on the 30 billion dollar-a-year poultry industry. The epizootic currently affecting Asia, Europe and Africa has prompted the destruction of tens of millions of chickens. The wild bird monitoring plan is part of President George W. Bush's National Strategy for Pandemic Influenza Preparedness. Bush allocated 29 million dollars for implementation of the wild bird monitoring plan. Since 2003, about 200 people have been infected with H5N1, half of whom have died. The disease so far is spreading by direct contact with infected birds, not by person-to-person transmission. However, experts fear the virus may mutate to a human variant, increasing the likelihood of a pandemic. js/fgf/gd AFP 211157 GMT MAR 06 #112Posted 2006-03-21 21:23:31
Russian authorities began vaccinating birds at Moscow's
Zoo MOSCOW (AP) _ Russian authorities vaccinated birds at Moscow's Zoo on Tuesday as part of a mass program for domestic fowl aimed at preventing the spread of deadly bird flu in Russia. But they had to catch them first, a task which proved beyond some of the zoo's workers, who chased after the uncooperative ones with nets. Workers hoped to safeguard the birds in case the deadly H5N1 virus spreads to Moscow. «We put the vaccine in the syringe and inject it into the bird's chest,» said Nataliya Istratova, the zoo's press secretary. «It's stressful for (the birds), but better to be in the hands of a doctor than in death's grip.» Russia's lower house, the Duma, heard testimony Tuesday from the country's leading sanitary specialist on measures being taken to deal with the spread of bird flu. Gennady Onishchenko told deputies that the country had «sufficient» supplies of vaccine and had set up a nationwide monitoring headquarters. «The situation is under control,» Onishchenko assured lawmakers. 211347 mar 06GM #113Posted 2006-03-21 23:02:19
WHO figures for bird flu cases in humans
March 21 (Reuters) - The World Health Organisation (WHO) said on Tuesday that bird flu has killed five people in Azerbaijan. Samples from 11 patients under investigation in Azerbaijan for possible H5N1 infection have now been tested at the WHO collaborating laboratory in the United Kingdom. Positive H5N1 results were obtained for seven of these patients. Five cases were fatal. The bird toll consists of some 200 million birds which have been culled. Following is a list of confirmed human cases of H5N1 from the WHO in Geneva. Total cases includes survivors.

More detailed testing by government laboratories or those affiliated with the WHO can take a week or more. The H5N1 virus remains mainly a virus of birds, but experts fear it could change into a form easily transmitted from person to person and sweep the world, killing millions within weeks or months. So far, most human cases can be traced to direct or indirect contact with infected birds. REUTERS 211628 Mrz 06 #114Posted 2006-03-21 23:07:37

CAIRO, March 21 (Reuters) - Egypt reported a fourth suspected case of bird flu in humans on Tuesday, in a 17-year-old boy whose father had an outbreak of the disease on his chicken farm in the Nile Delta on Saturday and Sunday. Health Minister Hatem el-Gabali, quoted by the state news agency MENA, said the boy was taken to hospital in the town of Tanta on Sunday and was receiving Tamiflu treatment. His condition is "good and stable", he added. Laboratories are testing samples from the boy for the deadly virus, the minister said. 211625 Mrz 06 ENDOFMSG #115Posted 2006-03-22 17:45:47
Poor nations need help fighting bird flu
By Jim Loney ATLANTA, March 21 (Reuters) - Fewer than three dozen nations are capable of the early detection and quick response needed to contain rapidly spreading bird flu and other viruses that could threaten humans, a health official said on Tuesday. Combating the spread of the H5N1 avian influenza, which has killed 103 people worldwide since it reemerged in 2003, has become critical to governments across the globe because experts fear it could become a pandemic that could kill millions and cause catastrophic economic damage. "Developed countries are in position to practice satisfactory early detection and rapid response. Worldwide, only 20 to 30 countries are able to do that currently," said Dr. Bernard Vallat, director-general of the World Organization for Animal Health. "All the others, 140 or more, need help." Rich countries need to help poorer ones with detection programs and compensation for farmers to prevent the global spread of "zoonoses," diseases that can spread from animals to humans, Vallat said at the International Conference of Emerging Infectious Diseases in Atlanta. At a January conference in Beijing, governments and organizations pledged $1.9 billion for a global "rapid containment" program for bird flu. The World Health Organization said on Tuesday that bird flu killed five young people in Azerbaijan, taking the global death toll to 103 since it reemerged in late 2003. The virus has spread with alarming speed in recent weeks, pushing into Europe and Africa. The United States said this week it expects to see its first cases of bird flu this year. Scientists say the virus is mutating and could evolve into a form that would pass easily from human to human, potentially causing a pandemic that could kill millions because people would have no immunity. The issue of ways to contain it has been a primary topic of debate between hundreds of health experts from some 80 nations gathered in Atlanta this week for the infectious disease conference. Vallat named European Union nations, the United States, Canada, New Zealand and Australia as having the ability to respond quickly to an outbreak of bird flu or another threatening virus. Experts say outbreaks can be contained by early detection and a quick response. U.S. wildlife officials, for example, are monitoring Pacific bird migration routes for signs of bird flu with the hope of tracking infected birds and giving advance warning to U.S. poultry producers. But in many poor countries, it is nearly impossible to know what diseases are circulating because of poor surveillance programs. "There are parts of Africa without any surveillance," Vallat said. "Diseases can circulate for weeks in some parts of Africa without being known by the authorities in the capital." One of the keys to early detection is a plan to compensate farmers if governments decide to destroy infected flocks. Outbreaks of H5N1 have forced the destruction of more than 200 million birds. But in poor countries, farmers may be reluctant to report mysterious deaths in their flocks because they are uncertain whether they will be paid for the lost birds. "You can't go to poor areas and take away the people's livelihoods and the food supply and not have them compensated. It's just not right," said Dr. Keiji Fukuda of the World Health Organization. European nations such as France, Germany and the Netherlands have compensation plans, as do Vietnam, Thailand and other Asian countries. But many nations have not addressed the issue. Vallat said the World Bank and other international financing organizations were working to develop "sustainable" compensation programs. For example, the World Bank made a loan to Vietnam on the condition that it establish a sustainable compensation plan for farmers. REUTERS 212306 Mrz 06 ENDOFMSG #116Posted 2006-03-22 17:51:48
WHO says China to release bird flu samples following
criticism BEIJING (AP) _ China has agreed to give the World Health Organization bird flu samples from animals following complaints that Beijing was hampering vaccine research by withholding such samples, WHO officials said Wednesday. The agency expects to receive about 20 virus samples within a few weeks, Dr. Julie Hall, an official of the WHO office in Beijing, said at a news conference. Experts say such samples are critical to research on diagnostic tools and vaccines, and they have criticized China's Agriculture Ministry for refusing to release them to foreign scientists. Chinese officials have been accused of withholding samples to boost the status of China's own scientists and possibly increase chances that they might develop a potentially lucrative vaccine. The WHO regional director for Asia, Dr. Shigeru Omi, also said China has to improve its surveillance of animals for possible bird flu outbreaks. None of China's 15 human cases of bird flu occurred in areas where authorities had warning of possible infection due to outbreaks detected in poultry, Omi said at a news conference. 220349 mar 06GMT #117Posted 2006-03-22 18:00:42
Vietnam cracks down on smuggled poultry from China
HANOI, Vietnam (AP) _ Vietnam has stepped up its crackdown against poultry smuggled from China in an effort to prevent the bird flu virus from reinfecting domestic flocks, officials and state-controlled media reported Wednesday. Agriculture Minister Cao Duc Phat was quoted by Nong Nghiep (Agriculture) newspaper as telling the National Steering Committee on Bird Flu Prevention and Control on Tuesday that smuggled poultry from China is a «direct threat» to Vietnam. «Due to huge differences in the price of poultry domestically and that in China, smuggling of poultry across the border has been very active,» Phat was quoted as saying «This is a direct threat and it must be prevented at any price.» Vietnam has reported no bird flu outbreaks in poultry over the past three months and no human infections since last November. Phat urged authorities in the four northern border provinces, considered major consumers of smuggled poultry, to eliminate places where smuggled poultry were sold, it said. The minister also said several government teams will be set up this week to inspect the smuggling situation, the newspaper said. 220536 mar 06GMT #118Posted 2006-03-22 18:25:52
Resolved: Why bird flu virus is not contagious between humans
by Richard Ingham PARIS, March 22, 2006 (AFP) - Virologists say they understand why bird influenza in its present form does not spread among humans, and the finding suggests the world may have a precious breathing space to prepare for any flu pandemic. The reason lies in minute differences to cells located in the top and bottom of the airways, the team report in Thursday's issue of Nature, the weekly British science journal. To penetrate a cell, the spikes that stud an influenza virus have to be able to bind to the cellular surface. The virus spike is like a key and the cell's docking point, called a receptor, is like a lock. They both have to be the right shape for the connection to happen. Scientists in the United States and Japan, led by Yoshihiro Kawaoka of the University of Wisconsin at Madison, found that avian influenza viruses and human influenza viruses home in on slightly different receptors. The receptor preferred by human flu is more prevalent in cells in the mucous lining of the nose and sinus as well as the throat, trachea and bronchi. But the receptor preferred by bird flu tends to be found among cells deep in the lung, in ball-like structures called the alveoli. It means H5N1 is likely to hole up in a part of the airways that does not cause coughing and sneezing -- the means by which the flu virus is classically transmitted among humans. Bird flu is lethal to poultry and dangerous for humans in close proximity to infected fowl. It has claimed more than 100 lives, according to a World Health Organisation (WHO) toll. But, apart from a few anecdotal cases, the mortality has occurred exclusively by direct transmission from birds to humans and not among humans themselves. To acquire that contagiousness would open the way to a pandemic. "Our findings indicate that H5N1 virus... can replicate efficiently only in cells in the lower region of the respiratory tract, where the avian virus receptor is prevalent," the paper says. "This restriction may contribute to the inefficient human-to-human transmission of H5N1 viruses seen to date." So what would turn H5N1 into a pandemic virus? First and foremost, it would need mutations in the spike, the haemagglutinin (HA) molecule, to enable the virus to bind to cells in the upper respiratory tract. This would enable the virus to spread via coughs and sneezes and nasal mucus, which are caused by irritation to the upper airways. To boost its pandemic potential, the virus also needs changes in its PB2 gene, which controls an enzyme essential for efficient reproduction. "Nobody knows whether the virus will evolve into a pandemic strain, but flu viruses constantly change," said Kawaoka. "Certainly, multiple mutations need to be accumulated for the H5N1 to become a pandemic strain." The findings suggest scientists and public health agencies may have more time to prepare for an eventual pandemic of avian influenza, the team believe. Kawaoka's team exposed various tissues from the human respiratory tract to a range of viruses in lab dishes. The viruses were the human strains H1N1 and H3N2 and the bird strains H3N2 and H4N6. In addition, there were two H5N1 samples, one taken from a human victim in Hong Kong and one from a duck in Vietnam. Flu viruses reproduce sloppily, which induces slight changes in their genetic code. This movement is called antigenic drift, and explains why seasonal flu viruses keep changing and new updated vaccines are needed. But they can also make big changes, called antigenic shift, in which new genes are brought in, thus creating a new pathogen against which no one has immunity. A novel flu virus that emerged after World War I killed as many as 50 million people. By closely monitoring viruses from people infected with avian flu, scientists can get a early warning as to whether these strains are mutating into forms that will make it easier to fit into human receptors, Kawaoka said. ri/bm AFP 220558 GMT MAR 06 #119Posted 2006-03-22 18:32:06
India completes bird flu tests, clean-up progresses
MUMBAI, March 22 (Reuters) - India has checked and cleared more than 400,000 people for bird flu in western India, officials said on Wednesday, as a massive clean-up drive to contain a second outbreak in poultry neared completion. The latest outbreak -- in backyard poultry in the Jalgaon district of Maharashtra state -- was the highly pathogenic H5N1 strain of bird flu, but it has not infected people so far. "We have completed monitoring 440,000 people in and around the four affected villages of Jalgaon. The week-long vigil is over and there are no human cases," Vijay Satbir Singh, Maharashtra's top health official, told Reuters. Of the hundreds of thousands of people monitored, only four were quarantined in Jalgaon either with flu-like symptoms or as a precaution, but they were expected to be discharged later on Wednesday after their test results were negative for bird flu. More than 90,000 birds have been culled in Jalgaon and authorities are concentrating their efforts on cleaning up four villages spread over 1,100 square km (425 square miles) in the district where backyard poultry were found infected with bird flu. The clean-up operation -- disinfecting homes, backyards and drains -- could be over in two days, officials said. Jalgaon is next door to Nandurbar district where the first outbreak occurred last month. #120Posted 2006-03-22 18:35:53
US schools urged to take bird flu preparations seriously
WASHINGTON (AP) _ U.S. schools _ recognized incubators of respiratory diseases among children _ are being told to plan for the possibility of an outbreak of bird flu. Federal health leaders say it is not alarmist or premature for schools to make preparations, such as finding ways to teach children even if they've all been sent home. Other issues include working out who closes schools and quarantines children, who will keep the payroll running and how to provide food to children who count on school meals. The deadly H5N1 strain of bird flu has infected more than 170 people and killed roughly 100. Officials say bird flu is likely to arrive in U.S. birds this year. Experts fear the virus could change into a form that passes easily among people. In North Carolina on Tuesday, Education Secretary Margaret Spellings joined Health and Human Services Secretary Mike Leavitt to encourage schools to prepare. Spellings said schools must be aware that they may have to close their buildings _ or that their schools may need to be used as makeshift hospitals, quarantine sites or vaccination centers. 220832 mar 06GMT #121Posted 2006-03-22 18:41:24
Indonesia bird flu campaign exposes loopholes
By Tomi Soetjipto PURWAKARTA, Indonesia, March 22 (Reuters) - Armed with vaccines and green rubber boots, veterinarian Sri Wuryasturati is ready to hit the road for Indonesia's anti-bird flu campaign. Except she doesn't have the most essential item to get going: a motorcycle. Dressed in a crisp brown civil servant's uniform and scarf, the 42-year-old eventually takes off hours later to join hundreds of veterinarians at the forefront of efforts to contain bird flu in Indonesia, which has the world's second highest number of human deaths from the disease. "We have got the vaccines ready," she said, pointing to a refrigerator full of vaccines for poultry. "But sometimes some of us can't go out because there are no vehicles." Without motorcycles, it is impossible for vaccinators to reach villages in the morning before locals release their backyard chickens into the fields. And there are lots of villages in Indonesia, a country of 220 million people spread across thousands of islands. Although Indonesia has launched high-profile, door-to-door checks of poultry and birds in some provinces, the country remains vulnerable because of poor planning and surveillance. Jakarta has set up a national team to combat bird flu, but its members and volunteers only reach areas in the capital while those in provinces rely on their own networks of vaccinators. WEAKNESS Yoke Sudarbo, a programme manager at Partnership, a U.N.-sponsored non-governmental organisation, said lack of coordination mirrored the state of bureaucracy in Indonesia. "The weakness in handling bird flu is an example of inadequate public services in Indonesia and it highlights the country's poor infrastructure," said Sudarbo. Government officials in Jakarta said they were in control. "Support systems such as two-wheeled and four-wheeled vehicles will be provided, we are working on that," said Mathur Riyadi, head of the Agriculture Ministry's poultry department. He added the government had distributed leaflets to government offices, outlining basic health and hygiene procedures and safe ways to cook chicken. Indonesia has had 22 confirmed deaths from the H5N1 strain of the avian flu virus since 2003 and half of those deaths have occurred this year. The rising toll is worrying U.N. health officials who fear the more the virus spreads in birds, the more human cases there will be and the greater the risk H5N1 might mutate into a form that could pass from person to person. If such a mutation occurs, it could spark a pandemic in which millions could die. Globally, the virus has killed at least 103 people since 2003, the majority in Asia where many people live side-by-side poultry. For the moment, it remains hard to catch from birds. In Indonesia, most bird flu cases in humans have been in or around Jakarta. But the virus has been detected among poultry in about two-thirds of the country's 33 provinces. HOSTILITY A big stumbling block is opposition to the control campaign from villagers. "People get hostile sometimes. Some even hide their chickens, which is silly because we can still hear the noise," said Sri the veterinarian. Despite a 30 billion rupiah ($3.3 million) scheme to cull fowl within a kilometre radius from the point where the virus is found, some workers are afraid to kill the birds as there is no legal apparatus to act freely. Moreover, there is no monitoring system as in Thailand to alert authorities in case of a suspected outbreak. In Thailand, the government has tagged its bird flu monitoring efforts onto a nationwide network of 800,000 health volunteers, set up decades ago as a first line of defence against ailments such as diarrhoea, tuberculosis and chickenpox. With each volunteer assigned to monitor between 10 and 20 households in Thailand, as well as educate them about the risks and symptoms of bird flu, officials are confident any outbreak in either poultry or humans will not go unnoticed for long. "If a chicken dies unusually, we will know about it within the day," said 58-year-old Manop Sungyont, who has been a health volunteer for 29 years in Suphan Buri province, 100 km (60 miles) northwest of Bangkok. In the event of a possible outbreak, the likes of Manop pass the information up a command chain to either animal or human health officials, triggering the swift arrival of expert teams to collect samples, treat victims or start culling.

Afghanistan begins bird flu cull
KABUL, March 22 (Reuters) - Afghan workers in protective suits and masks fanned out through a Kabul neighbourhood of low, mud-brick homes on Wednesday, rounding up chickens and spraying disinfectant, hoping to stamp out the H5N1 birdflu virus. The H5N1 virus was confirmed in chickens in the capital and an eastern province last week and is assumed to have spread to at least three other provinces, officials said. The cull was delayed for several days while impoverished Afghanistan tried to find protective suits for the teams. Eventually, the U.S. military provided enough to get going. "Two cases were confirmed in this village, some chickens already died here, some pigeons also died here," Azizullah Osmani, chief of the Agriculture Ministry's veterinary department, told reporters as the cull was launched. Bird flu has killed 103 people since late 2003, most of them in Asia. Although difficult for humans to catch, experts fear the virus could mutate into a form that passes easily between people and trigger a pandemic that could kill millions. There have been no human cases in Afghanistan but there is concern that, with veterinary and health sectors still recovering from decades of conflict, the country could struggle to contain an outbreak. Many Afghan chicken farmers and traders are illiterate and have little knowledge of the disease. Authorities have yet to produce much public information on the danger. Osmani said that as well as collecting and culling all chickens in the area, pens and yards were being sprayed with disinfectant. Teams would monitor a zone 5-10 km (3-6 miles) from the site of the cull, he said, and if sick chickens were found, the process would be repeated there. Culls would be conducted in at least three other areas of Kabul province, he said. Residents of the neighbourhood in the west of Kabul, where many people keep a few chickens in back yards, appeared resigned to losing their birds. One man, Mohammad Ibrahim, said his 20 chickens had all suddenly died as had a cat that ate one of the carcasses. Officials have said it will be important to compensate people whose chickens are culled. Afghanistan's poultry industry was decimated by several years of drought up to 2005 and is small-scale with only an estimated 12 million chickens in the country.

H5N1 bird flu spreads to Gaza Strip - official
RAMALLAH, West Bank, March 22 (Reuters) - The deadly H5N1 strain of bird flu which struck Israel last week has spread to the Gaza Strip, a Palestinian agriculture official said on Wednesday. The official offered few other details about the outbreak except that the virus was detected in areas close to the Israeli border. The H5N1 virus has also been detected in neighbouring Egypt. Israel has been culling hundreds of thousands of turkeys and chickens after an outbreak of the deadly avian virus at several farms near the Gaza Strip. The Palestinian Authority on Tuesday declared a state of emergency in hope of preventing the spread of the virus. The virus has rippled out from Asia to the Middle East, Europe and Africa in recent months, with migratory birds seen as the main culprits in spreading bird flu. Experts fear the virus will mutate into a form that passes easily from person to person, sparking a pandemic in which millions could die and which could cripple the global economy. Bird flu can infect people who come into close contact with infected poultry and has killed nearly 100 people since late 2003. Egypt reported a fourth suspected case of bird flu in humans on Tuesday. Israeli officials have said there have been no cases of humans contracting the virus in Israel. 221344 Mrz 06 ENDOFMSG #124Posted 2006-03-22 21:58:04
New H5N1 bird flu case found in Romania
BUCHAREST, March 22, 2006 (AFP) - Twelve new cases of the potentially deadly H5N1 bird flu virus have been confirmed in domestic poultry in a village near Bucharest, the local veterinary health authority said Wednesday. The village, Magurele, 15 kilometers (nine miles) from Bucharest, was put under quarantine and authorities began culling over 1,000 poultry Wednesday as a result, it added. "Disinfection filters were placed at the entrance and exit of Magurele and residents are forbidden from leaving the village for a period of two to three weeks," local veterinary health authority chief Valentin Viocu told AFP. "It is necessary to respect the quarantine to prevent the virus from spreading towards Bucharest," he added. The H5N1 virus has been found in some 50 villages in Romania, making it one of the European countries most affected by the disease. lc-ssw/msa/smc AFP 221440 GMT MAR 06 #125Posted 2006-03-23 19:28:39
the avian flu in israel was apparently spread by sub cntractor that provides services to the turkey coop industry;
gaza chicken growers refuse to destroy any chickens until they actually get money in their hands (pretty dumb of them id say since they can die just like us - my own comment; bina) and most people in gaza raise chickens like in issaan thailand: running loose in the yard, crowded conditions and 'primitive' hygiene methods... new case of turkeys in moshav bekaa (in the jordan valley).... wait and see.... |
