Man suspected of contracting bird flu in Thai north

http://news.xinhuanet.com/english/2008-02/08/content_7582065.htm

BANGKOK, Feb. 8 (Xinhua) -- A man in Thailand's northern province Phichit was suspected of contracting bird flu as he was found with high fever for two days after contact with dead chickens, media here reported Friday.

Khanueng Limchai, 32, was admitted to the Phichit Provincial Hospital at 11 p.m. (1600 GMT) Thursday night, according to news network The Nation.

He had high fever for two days after he found dead chickens stuffed in a bag and took them home to feed his dogs. His wife earlier took him to a clinic and the clinic sent him to the provincial hospital on suspicion that he had contracted bird flu.

His blood sample has been sent for checking. The result of blood test would be known in two days.

On Jan. 24, Thai authorities confirmed a new bird flu outbreak has been detected at a farm in northern province Nakhon Sawan neighboring Phichit, after laboratory test found H5N1 Virus in dead chicken at the farm.

Bird flu takes heavy toll on Andhra poultry sector

http://www.commodityonline.com/news/topstory/newsdetails.php?id=5372

HYDERABAD: With the poultry products’ movement coming to a halt due to the spread of bird flu in West Bengal, Andhra Pradesh’s poultry sector is struggling to survive.

The ban on poultry movement in north-eastern states has already hit the Andhra producers badly. However, now
Maharashtra and Chhattisgarh governments are also planning to stop entry of poultry products to the respective states.

The ban could lead to sharp increase in the prices of egg and broiler chicken in Mumbai in the next few days.

Andhra Pradesh sends nearly 50 lakh eggs to Maharashtra every day. Sudden stoppage could trigger the price hike.

Though the ban notifications would not mention the name of any state, Andhra Pradesh is going to be the biggest sufferer of such restrictions.

Of the 5.5 crore eggs the state produces, 1.40 crore eggs go to West Bengal and North-East, and another 1.30 crore lakh to the central and northern states.

Worried, a delegation met Andhra Pradesh Chief Minister Y S Rajasekhara Reddy to ask him to take up the issue.

They urged the chief minister to talk to Union Agriculture Minister Sharad Pawar and Maharashtra Chief Minister Vilasrao Deshmukh and persuade them to lift restrictions on poultry movement.

Addressing a press conference after meeting the chief minister, the delegation said there was no absolute problem either in Maharashtra or in Andhra Pradesh. There is no rationale behind the ban.

The National Egg Coordination Committee, Andhra Pradesh, said that local traders’ lobby might have brought pressure on Maharashtra to impose the ban on poultry traffic.

"Several of these dogs were found dead in a large pool of blood, and when we did autopsies on them their lungs were full of blood, they had other organs involved," said Pizano.

The above comments describe dogs dying of a “mystery illness” in Miami Dade county in Florida. Although a bacterium, Streptococcus zooepidemicus, has been isolated, the deaths are almost certainly due to influenza, which is likely to be H3N8.

H3N8 has been causing problems at kennels for several years, with multiple outbreaks in Florida.

Identification of the serotype and release of sequence data would be useful.

Bird flu affects Indian camps

http://www.straitstimes.com/Free/Story/STIStory_204685.html

NEW DELHI - BIRD flu could claim some unlikely victims - the aspirations of India's badminton players.

The Badminton Association of India (BAI) announced on Thursday that it was calling off training camps ahead off this month's Thomas and Uber Cup qualifiers due to a shortage of quality feather shuttlecocks.

It sent home over 30 players, after blaming the state-run Sports Authority of India (SAI) for not supplying the stock and stopping the federation from importing.

The qualifiers are due to be staged in Ho Chi Minh City, Vietnam, from Feb 19-24.

India, who qualified for the Thomas Cup Finals last time, are in Group C with Japan and Pakistan.

Three months ago, India's agriculture ministry barred the import of feathers because of the bird flu menace in Asia.

Top shuttlecocks are made with goose feathers, which are derived mostly from China and Taiwan.

Since then, the association has been unable to buy feather shuttlecocks, said BAI president V.K.Verma.

'It is a very lackadaisical attitude,' he said. 'They're supposed to provide shuttlecocks, but are doing the game a great disfavour.

'We can't have our 30 best shuttlers, juniors and seniors, twiddling their thumbs with only five tournaments left to qualify for the Olympics.'

Manufacturers had offered to ship chemically-treated shuttlecocks that passed a bird flu inspection by Hong Kong authorities, but the Indian government has yet to lift the ban.

Verma said the state agency had not even done the initial paperwork on a request forwarded six weeks ago.

The shuttlecock shortage could also affect the Indian Open, which is scheduled for April 1-6 in the southern Indian city of Hyderabad.

Fowl death alerts Thai northeastern province

http://news.xinhuanet.com/english/2008-02/10/content_7586001.htm

BANGKOK, Feb. 10 (Xinhua) -- Twenty-six districts of Thailand's northeastern province of Khon Kaen were on high alert of deadly bird flu after local fowl died mysteriously last week, the provincial governor said on Sunday.

The 26 districts of the province which have been put on the watch list are being observed particularly closely, with x-rays and health checks being carried out rigorously by authorities, Governor Panchai Bawornrattanapran said.

Panchai was quoted by the Bangkok Post's web news as saying that15 chickens were reported dead in Muang Kao district in the past week alone but maintained preventative measures have already been taken.

"Over 200 chickens within a five-kilometer radius of places where chickens died mysteriously have already been destroyed," he said.

He urged locals to help authorities look out for symptoms of the virus and underlined the importance of eating cooked chicken meat and eggs.

Thailand is among the countries hardest hit by the deadly H5N1 virus, having recorded 24 human cases, including 16 fatalities, since the outbreak in 2004.

Bird flu spreads to another Bangladesh district

http://news.yahoo.com/s/nm/20080210/sc_nm/birdflu_bangladesh_dc

DHAKA (Reuters) - Bird flu has spread to another district in Bangladesh despite efforts by authorities to contain it, taking the number of affected districts to 40, officials said on Sunday.
ADVERTISEMENT

Health workers culled nearly 12,000 fowls after tests confirmed some chickens had died from the avian influenza virus in the northeast, livestock officials said.

The H5N1 virus, first detected in Bangladesh in March last year, was quickly brought under control through aggressive measures, including culling. But follow-up monitoring eased in later months prompting the disease to reappear, experts say.

So far, no human infections have been reported in Bangladesh, a densely populated nation with millions of backyard poultry and thousands of chicken farms.

The interim government has enhanced compensation for poultry farmers to encourage them to report and kill sick birds.

More than half a million birds to be culled across the country, but the virus has spread to more than half the South Asian country's 64 districts partly due to a lack of awareness.

Media reports said many children were seen smiling and playing with dead poultry. Even health workers have been seen burying dead birds without any protective gear.

The World Health Organization worries that the H5N1 strain, which has already killed more than 220 people worldwide since 2003, could mutate into a form that passes easily between humans and infect and kill millions.

Suspect H5N1 in Orissa India

http://www.recombinomics.com/News/02100803/H5N1_Orissa_Suspect.html

Recombinomics Commentary 22:52
February 10, 2008

Official sources , including KC Sasmal, chief district veterinary officer confirmed reports of bird deaths at a farm near Kesinga. "At least 55 birds have died over two days",he said.

The above comments describe suspect H5N1 in Orissa (see satellite maps here here here). Orissa has not confirmed H5N1, although there have been excessive poultry deaths in border areas and a precautionary cull has been ordered. The deaths described above are well south of the border with West Bengal, and would cause alam if H5N1 was verified.

The level of H5N1 in west Bengal poultry and wild birds suggests that the culling in West Bengal and Bangladesh will not prevent H5N1 from spreading into adjacent regions, with or without border culling.

Suspect H5N1 in Nadia West Bengal

http://www.recombinomics.com/News/02100802/H5N1_Nadia_Suspect.html

Recombinomics Commentary 18:18
February 10, 2008

over 1,300 chickens died of a mysterious disease in different poultry farms in Ranaghat-II block in Nadia. The symptoms of the disease are similar to avian influenza. The district authorities sent a team to collect samples and take note of the situation.

The above comments describe suspect H5N1 deaths in Nadia, West Bengal. Although there has been extensive culling in India in the region, H5N1 confirmations have been high in adjacent Bangladesh, in poultry and wild birds (see satellite maps here here here)

The likelihood that culling and border sealing will stop the spread is low. The most effective halt of confirmed H5N1 has been to limit testing.

KARACHI: Hospitals lack capacity to handle bird flu patients

http://www.dawn.com/2008/02/11/local1.htm

By Mukhtar Alam


KARACHI, Feb 10: No government hospital in the city is in a position to offer the much-needed treatment to bird flu patients in isolation, according to medical professionals who see the H5N1 virus that appeared in the country a couple of years ago as a serious threat to public health.

Questioning the major government hospitals’ capacity to handle bird flu cases, the experts say that in a situation when a majority of hospitals in the public sector are not up to the mark in critical care facilities, including isolation wards, biohazards protection wears and equipment, respirators and ventilators, it will be unwise to expect that they will to do the needful in case of bird flu pandemics.

Karachi is now included in the rank of cities of the world where the pathogenic avian influenza has crept in to stay for some time and as such danger to human paramedics should be a major concern, says an official expert on bird flu.

Poultry farmers, workers and consumers, however, appear not very much frightened of the infectious disease while the doctors conscious of the danger of avian influenza underline the need for a dedicated programme on bird flu cases in humans, proper funding, demarcation of suspected areas, and specialisation in the disease in addition to enhancing the hospitals’ capacity for handling such patients, says an official.

In December, the federal health ministry and the World Health Organisation confirmed the first death of one of the eight people, who were tested positive for the H5N1 bird flu virus, in the NWFP since October last.

Referring to the development, experts say that a single human case across the country may be a start and as such the hospitals needed to get ready. To study the traces of bird flu, there is also a need that patients who arrive with flu symptoms and have a relation with poultry should be routinely asked about their recent activities and environment they work in.

A senior doctor at a government hospital says that if and when the pandemic bird flu H5N1 strikes a hospital it should be able to respond to an influx of potentially contagious persons, panic-stricken victims and their families by keeping them calm, safe and secure.

CDC guidelines

According to the guidelines recommended by the Centres for Disease Control and Prevention, avian flu H5N1 patients need to be placed in a private room that has monitored negative air pressure in relation to the corridor and anteroom.

Moreover, experts say that a medical team handling the bird flu patients should include a lung specialist, a paediatrician, an anaesthetist, a clinical pathologist, a microbiologist and specially trained nurses and have high-tech isolation rooms that can accommodate up to six patients with biohazards protection facilities.

A survey of major hospitals, run by federal, provincial and district governments, suggests that none of them are prepared to handle and provide relief to bird flu patients. They have less space for a major modification as they are already over-occupied with routine exercises and procedures and would hardly be able to spare staff and necessary machines for the purpose.

Dr Rashid Jooma, Executive Director of Jinnah Postgraduate Medical Centre, said that it was not possible for the hospital to dedicate some wards exclusively for isolation purpose. “Besides, we shall have to spare respirators and ventilators for bird flu patient, which is surely a costly affair,” he added.

He said that the medical centre was ready to receive only the confirmed bird flu cases. “Two rooms have been demarcated in a ward to accommodate two patients at the maximum with the view that the JPMC cannot work as a frontline hospital and the Sindh government must have a full-fledged isolated ward or centre for infectious disease patients,” he added.

In reply to a question, Professor Jooma said that he had heard that the federal government was sending special equipment and protection gadgets to hospitals in Sindh, but nothing had reached here so far.

A senior citizen recalls that a hospital exclusively for infectious diseases functioned under the municipality some 25 years back at a site where the Civil Hospital Karachi’s out-patient department works today. The authorities failed to understand the significance of establishing such a centre or maintaining the existing one and as such hospitals are not prepared for an extra ordinary situation, he added.

CHK’s Medical Superintendent Dr Kaleem Butt said that although the hospital lacked a well-equipped ward for the purpose, the administration had started gearing up through its available resources to take burden of three to four bird flu patients in cubical rooms. He agreed that the existing isolated cubical rooms and the hall did not have ventilators and other systems required for bird flu patients with severe respiratory problems. But, he added, in extreme emergencies such patients could be shifted to the coma care centre or the intensive care unit of the hospital for ventilators.

Six isolation wards

An official of the city government had indicated some weeks ago about the government’s plan to establish six isolation wards, each housing two patients of bird flu. He had mentioned that the federal government had been approached for special training of the personnel concerned and supply of relevant wears and equipments. However, the scheme is still a far cry of doctors, says an insider.

What next for bird flu in Jakarta?

http://www.thejakartapost.com/detailcity.asp?fileid=20080212.C05&irec=4

More "visitors" have been visiting Jakarta than ever during the last three years.

First and foremost among these visitors are floods and the H5N1 virus, which are both more prevalent during the rainy season.

Hype surrounding the virus, or bird flu as it is more commonly known as, follows the same pattern every year. The media kicks off the frenzy with reports on bird flu cases. It also offers ideas as to how victims may have contracted the virus. The central and local governments then jump on board, offering promises and policies almost identical to what they offered the previous year. Then the wet season ends, cases decrease and the hype dies down.

Responding to the latest cases of bird flu in Jakarta this month, Governor Fauzi Bowo had nothing better to say than echo promises his predecessor Sutiyoso made a year ago.

"We will strengthen restrictions on backyard farming and speed up the relocation of poultry farms from the city," he said.

The new location for these farms was to be the same as last year: Rawa Kepiting in East Jakarta.

Even after President Susilo Bambang Yudhoyono and his ministers visited City Hall to discuss the bird flu issue and flood control recently, the first directly elected governor had nothing new to say.

During Fauzi's first 100 days in office, bird flu certainly did not appear to be on the top of his list of priorities.

The draft of this year's city budget includes no special arrangements to tackle bird flu, nor does it mention anything about the poultry industry. Fauzi chose to focus on fighting dengue fever during the first few months of his tenure.

But if you were in Fauzi's position, it is likely you would also find it hard to make bird flu an emergency issue. Bird flu seems trivial compared to other illnesses that have plagued the city for decades, including dengue fever and diarrhea.

In 2006 when 11 cases of bird flu were recorded in the city by the health agency, 24,266 cases of dengue fever were reported with 46 fatalities.

The hype surrounding bird flu is generated more by the central government, which is more tuned in to international panic regarding the illness.

It is, of course, very reasonable to worry about bird flu.

Unlike dengue fever, which can be caused by just three viruses, researchers have proven that the H5N1 virus could easily mutate into more powerful viruses resistant to existing medication.

No researcher has found proper vaccines to prevent bird flu, with evidence suggesting the H5N1 virus is resistant to the medication used to treat it -- oseltamivir.

European public health specialists have also identified that the H5N1 virus is significantly resistant to the drug Tamiflu, which is the world's most widely purchased influenza medicine.

These reports are certainly frightening, but are they enough to get the administration to wake up to the threat bird flu poses?

I certainly doubt it. The recycling of last year's policies regarding bird flu by the current administration strongly backs up this belief.

Fauzi restated his policy regarding bird flu to the media to soothe the troubled minds of members of the public -- and members of the international community -- in light of the fact the number of bird flu victims in Jakarta is rapidly increasing.

It would not be that hard for the administration to battle bird flu. It made a good start last March when it closed down most backyard poultry farms in the city.

The Jakarta Health Agency recorded no new cases of bird flu between April and August 2007. One could argue that the absence of rain was the main reason for this, but compared to 2006 when the city recorded at least one case of bird flu per month, perhaps the policy worked to an extent.

The problem is that Fauzi, just like any other democratically elected leader, reacts according to the impact of problems on the community. And in the case of Jakarta, dengue fever and traffic congestion seem to affect more people than bird flu. Sure, these problems are less deadly, but they have the potential to give the governor a large headache when fingers are pointed at him.

Bird flu and the gauntlet of other existing diseases in the city should be viewed as a sign that the bar should be raised in terms of quality of life.

Of course the administration could work harder to eradicate bird flu from the city, just like administrations in the past eradicated other illnesses. But bird flu would not be the last illness to scare the residents of Jakarta.

Perhaps -- God forbid -- Fauzi will wait until bird flu affects the number of people currently inconvenienced by Jakarta's traffic chaos before he does anything about it.

Most of districts in Bangladesh affected by bird flu

http://news.xinhuanet.com/english/2008-02/12/content_7592796.htm

DHAKA, Feb. 12 (Xinhua) -- The bird flu which is spreading fast in Bangladesh recently has so far affected 40 out of the total 64 districts of the country, leading English newspaper The Independent reported Tuesday.

According to latest statistics, 560,000 poultry birds of 228 poultry farms in 40 districts have been culled across the country since the detection of the bird flu in Bangladesh in March last year.

Special Assistant in charge of the Livestock Ministry Maniklal Samaddar said on Monday that the government had taken all-out steps to check the spread of the bird flu.

Earlier, Samaddar said that so far 823 people were tested in the country but no bird flu virus was detected among them.

However, he urged the traders of kitchen markets to extend cooperation to the government in building awareness among the public.

In this regard, he mentioned that local government representatives, teachers of educational institutions and Imams of mosques were sent letters to create awareness regarding bird flu.

The avian influenza virus was first detected in a poultry farm in Savar, about 30 km northwest of Dhaka, in March 2007.

The situation has been getting worse since last month as the bird flu virus is spreading fast across the country, according to local media reports.

Indonesia confirms 127th case of human bird flu

http://www.abs-cbnnews.com/storypage.aspx?StoryId=109024

Agence France-Presse

JAKARTA - The 14-year-old daughter of an Indonesian woman infected with bird flu last month was also confirmed as carrying the virus on Wednesday, the health ministry said.

The teenager, the nation's 127th case, was in a critical condition at Jakarta's Persahabatan hospital, where her 38-year-old mother was admitted for treatment on February 1, the ministry and doctors said.

The often deadly H5N1 strain of bird flu has claimed 103 lives in Indonesia, making it the worst-hit nation.

"She tested positive in both test results," health ministry spokeswoman Lily Sulistyowati told AFP, referring to the girl.

Two positive results of tests on blood and tissue samples are needed before Indonesian authorities confirm a human bird flu infection.

Muchtar Ikhsan, a doctor treating the latest case, told AFP that the teenager was admitted on February 8 and was gravely ill, but her mother was improving.

"The girl... is in an ICU (intensive care unit) and is being assisted by a ventilator," he said.

The mother and daughter came from West Jakarta's Kaliderest district, which lies next to the satellite city of Tangerang.

Nine people have died from bird flu in Indonesia so far this year, all of them from Jakarta and its surrounding sprawl.

Earlier, the ministry said that the infected mother lived in a neighbourhood where backyard poultry are kept, but the health ministry spokeswoman said Wednesday that the pair had visited relatives where neighbours kept poultry.

Experts fear that the virus, which is usually spread directly from a bird to a human, could mutate into a form easily transmissible between people, sparking a deadly global pandemic.

The concern stems from past influenza pandemics -- one in 1918, just after the end of World War I, killed 20 million people worldwide.

Bird flu is now officially endemic across nearly all of Indonesia.

Bird flu kills a man in northern Vietnam, heron in Hong kong

http://hosted.ap.org/dynamic/storie...ME&TEMPLATE=DEFAULT&CTIME=2008-02-14-05-42-23

By MICHAEL CASEY
AP Environmental Writer

BANGKOK, Thailand (AP) -- Health officials in Vietnam warned Thursday that bird flu could spread after the virus killed its 49th victim in the country while a dead gray heron found in Hong Kong tested positive for the virulent H5N1 strain of the disease.

The 40-year-old man from Vietnam's Hai Duong province died Wednesday. The World Health Organization says at least 226 people have died worldwide from the virus since 2003. That number does not include the latest death in Vietnam.

The man died six days after being admitted to the national tropical disease hospital in the capital, Hanoi, said Nguyen Huy Nga, director of the Ministry of Health's Preventive Medicine Department.

"The danger of the bird flu virus spreading further remains very high," Nga said "We have repeatedly urged people to report sick poultry to animal health authorities and to refrain from eating sick birds."

Dong Van Chuc, director of the Department of Animal Health in Hai Duong, about 60 kilometers (40 miles) southeast of Hanoi, said nine of the man's 12 fighting cocks had died since late January.

Meanwhile, tests confirmed a grey heron found dead in Hong Kong had the H5N1 virus after it was discovered near the territory's border with mainland China last Friday, the Agriculture, Fisheries and Conservation Department said in a statement.

The gray heron is a water bird that frequently visits Hong Kong in the winter.

The city's famed Mai Po bird sanctuary and aviaries in popular Ocean Park were closed for three weeks in late January after two bird carcasses found nearby were infected with the virus.

Most avian flu cases have been linked to contact with infected birds, but health officials believe limited human-to-human transmission has occurred among some family members in close contact.

On Wednesday, the WHO said the daughter of an Indonesian women who tested positive for bird flu has also contracted the virus in what could be a case of human-to-human transmission.

The 14-year-old girl was in critical condition at a Jakarta hospital, the WHO said on its Web site. The girl's mother has been hospitalized with the bird flu virus since Jan. 26.

Bird flu kills second Vietnamese this week

http://www.straitstimes.com/Latest+News/Asia/STIStory_206826.html

HANOI - BIRD flu has killed a second Vietnamese man this week, raising the country's death toll from the virus to 50, health officials said on Friday.

Hoang Van Doan, 27, from northern Ninh Binh province, 'died of H5N1 on Thursday evening,' said Nguyen Gia Binh, a senior official at Hanoi?s Bach Mai Hospital, where the man had been treated since early last week.

'Doan died of bird flu and became the 50th death in Vietnam so far,' said Nguyen Huy Nga, director of preventive medicine at the Health Ministry, adding that people close to Doan were now being tested for the virus.

Doan had slaughtered two chickens on January 31 and fell ill two days later, said Hoang Van Nam, deputy director of the Animal Health Department.

He was admitted to a provincial military hospital and was moved to the Hanoi hospital on February 12, where he later tested positive for the H5N1 strain of the virus.

He became Vietnam's third bird flu victim this year after a 40-year-old man died of pneumonia and kidney failure Wednesday at a Hanoi hospital, and a 32-year-old man died of similar symptoms on January 18.

Northern Vietnam has been in the grip of a month-long cold snap that experts say aids the spread of flu and other respiratory diseases because immune systems are weakened and people tend to spend more time indoors together. -- AFP

Dominican authorities have yet to control bird flu outbreak, the UN says

http://www.dominicantoday.com/dr/lo...-yet-to-control-bird-flu-outbreak-the-UN-says



SANTO DOMINGO.- The Dominican authorities still don’t have the sanitary control over bird flu, according to a the United Nations FAO report on the handling of that virus in the country, and says that in addition to Higüey and Santo Domingo, cases have been detected La Vega, San Pedro, Peravia, Barahona and San Juan provinces.

The document –which contains FAO’s conclusions and recommendations - also criticizes the authorities for failing to issue the decree which gives the Livestock Agency the power to automatically proceed to eradicate, restrict and slaughter birds.

To date the birds affected have been sacrificed, except in two farms of fighting roosters first identified in Higüey, outbreak which the FAO says continues open since the date it was reported.

Bird flu spreads to another Bangladesh district

http://www.reuters.com/article/latestCrisis/idUSDHA255572

DHAKA, Feb 15 (Reuters) - Bird flu has spread to another district in Bangladesh despite massive culling by authorities to contain the outbreak, officials said on Friday, bringing the number of affected districts to 42 out of 64.

Veterinary workers culled nearly 25,000 fowls after tests confirmed some chickens had died from the avian influenza virus in Comilla, in the south east, livestock officials said.

The H5N1 virus, first detected in Bangladesh in March last year, was quickly brought under control through aggressive measures, including culling. But it reappeared few months ago, apparently because of lax follow-up monitoring, experts say. Officials said the government was taking measures to contain the spread of the disease, but ignorance among millions of farmers across the impoverished country remained a stumbling block.

The government has raised compensation for poultry farmers to encourage them to report and kill sick birds as part of efforts to stamp out the outbreak.

More than 600,000 birds have been culled across the country against the virus since March 2007, but it continues to spread and now covers nearly two-thirds of the country of more than 140 million people.

So far no human infections have been reported in Bangladesh, a densely populated nation with millions of backyard poultry and thousands of chicken farms.

Experts fear the H5N1 strain could mutate or combine with the highly contagious seasonal influenza virus and spark a pandemic, especially in countries such as Bangladesh where people live in close proximity to backyard poultry.

Humans usually contract the virus only after close contact with infected birds, with the virus killing nearly two-thirds of the people it infects. The disease has killed more than 220 people worldwide since 2003. (Reporting by Ruma Paul; Editing by Alex Richardson)
