Hong Kong raises bird flu alert after H5 cases
Tue Dec 9, 2008 12:36pm GMT
By Donny Kwok
HONG KONG (Reuters) - Hong Kong health authorities raised the city's bird flu alert level to "serious" Tuesday after the H5 virus killed dozens of chickens at a farm, prompting the cull of 80,000 birds.
Laboratories in the city were now trying to determine the precise identity of the virus. A leading expert said it was likely to turn out to be the highly pathogenic H5N1 strain, which turns up regularly in flocks in Asia, parts of Europe and Africa.
"It's highly likely it's the highly-pathogenic H5N1 strain because others (other H5 strains) don't kill chickens like this. But this has to be confirmed," virologist Malik Peiris at the University of Hong Kong said.
Although H5N1 is mainly a disease among birds, it may mutate into a form that spreads easily among people.
If that happens, it could trigger a pandemic and kill millions. Even in its current hard-to-catch form, H5N1 has infected 387 people since 2003, killing 245 of them.
The city's Health Secretary York Chow said the affected farm was in Hong Kong's northern Yuen Long district near the border with China, which reported the unusual deaths of 60 chickens Monday.
"After a series of tests, we have confirmed this morning that the chickens died from the H5 virus," Chow told reporters, adding three dead chickens were tested and 20 faeces samples were taken.
CULLING
Workers clad in masks, white medical suits and black rubber gloves began the mass cull of some 80,000 birds at the farm on Tuesday afternoon, and were shown stuffing piles of chicken carcasses into black bin bags.
All chickens within a 3 km radius of the farm will be destroyed, along with birds at a wholesale market, Chow said.
Chicken farms in Hong Kong observe strict biosecurity measures to prevent disease and cross-infection between species, and chickens are vaccinated against the H5N1.
It was not immediately known how the chickens became infected. "It could be injection (of the virus) from wild birds. These (incidences) increase in winter. But it is not the only possibility," Peiris said.
The scenes were reminiscent of previous culls in 1997 and 2001, when the H5N1 virus prompted the slaughter of more than one million birds each time. In the 1997 outbreak, six people died.
Chow also ordered a precautionary three-week ban on poultry imports to contain any potential spread of the virus.
"We will ban all the outlets of all chickens from our farms for 21 days and also suspend all the imports of chicken and poultry including birds for the next 21 days," Chow added.
The last bird flu outbreak at a Hong Kong farm occurred in early 2003.

(AP) <!-- sphereit start -->Three dead chickens tested positive for bird flu in Hong Kong, prompting the city to suspend poultry imports for 21 days and begin slaughtering 80,000 birds, an official said Tuesday.
"We feel that Hong Kong is facing a new alert for bird flu," said York Chow, secretary for food and health.
Chow said the chickens, found Monday at a farm with 60,000 birds, had the H5 virus and further tests were being done to see if they had the deadly H5N1 strain.
The farm and neighboring poultry operations were declared part of an infected zone, and about 80,000 birds in the area would be killed to prevent the spread of the disease, Chow said.
He added that the 21-day ban on poultry imports would last through the Christmas holiday, a time when chicken is an important dish in celebratory dinners.
Hong Kong's biggest bird flu outbreak was in 1997, when the H5N1 strain jumped to humans and killed six people. That prompted the government to slaughter all 1.5 million poultry in the territory.
In 2001, the government also carried out a massive poultry slaughter, killing 306,000 birds in wholesale and retail markets and 951,000 in local farms to eradicate an outbreak of bird flu. The city now has 600,000 birds, Chow said.
At least 245 people have died of bird flu worldwide since 2003, according to the World Health Organization.
Hong Kong's government has been encouraging retailers to stop selling live birds, and the majority of shops have given up their licenses to sell live poultry. But eating fresh chicken is an important part of the culture and many shoppers still want freshly slaughtered birds.

Re: Hong Kong reports bird flu outbreak
HK reports first H5 bird flu cases on local farm in 6 years
HONG KONG, Dec. 9 (Xinhua) -- Dead chicken found at a Hong Kong farm have tested positive for the H5 strain of the avian influenza virus, which were the first confirmed bird flu cases on a local farm in about six years, health authority said Tuesday.
"Three dead chicken found at a chicken farm at Yuen Long district were H5 positive after our laboratory tests," York Chow, Secretary for Food and Health of the Hong Kong Special Administrative Region (HKSAR) government, told a press conference.
The alert level for bird flu has been raised to level "serious", he added.
Chow said two chicken farms in the areas have been closed down following the H5 cases and the HKSAR government has declared the areas within 3 kilometers of the affected farm an infected place and ordered the culling of about 80,000 chickens on the two chicken farms as well as on live poultry markets in the affected areas.
Health authority has decided to suspend the imports of live poultry to the city and the trading of live poultry on local markets for 21 days starting Tuesday.
"Those staff in close contact with live poultry in the farms are in good health now without any syndromes of H5 infection," Chow said, "but we will closely monitor the situation."
The Food and Health Bureau had put all local hospitals on high alert and require them to report timely the possible suspected human cases of bird flu infection.
"I also call on the public to observe personal hygiene," he added.
The Leisure and Cultural Services also announced on Tuesday the temporary closure of the Aviary Pagoda, or a bird watching site, in Yuen Long Park, which is within 3 km of the affected chicken farm as a precautionary measure.
Health staff have also been dispatched to clean certain local markets.
Chow said the local health authority has yet to make further tests to decide whether there has been any mutation in the strain of the bird flu virus involved.
The deadly H5N1 strain of the bird flu virus has killed many people worldwide over the past decade, in addition to leading to the culling of millions of domestic birds. Scientists worry that a mutation in the virus could enable its transmission from human to human, thereby leading to pandemic that could potentially kill millions.
Hong Kong has recently seen cold and dry weather conditions, in which the bird flu virus is typically more active, an epidemiologist at the University of Hong Kong said, adding that the risks of the bird flu cases spreading to retail markets were low. Hong Kong has been on high alert against a potential bird flu outbreak in the past years, with precautionary measures and an alert system that responds quickly. It has been trying to retrieve some of the live chicken trading licenses over the past months and centralize the processing of live chicken before they hit the market.

Re: Hong Kong reports bird flu outbreak
About vaccinated chickens:
Excerpts from today HK Secretary of Food Health press conference (Full: http://www.flutrackers.com/forum/sho...12&postcount=3)
Reporter:
Does that mean the vaccine is useless?
Secretary for Food and Health:
We cannot confirm this yet, but according to the facts received, there are also chickens with vaccination affected. So we have to investigate on both, whether the virus has changed or whether the vaccination has changed the immunity of them.
Reporter:
... or any changes of the...?
Secretary for Food and Health:
We cannot conclude in just a couple of days. Usually, virus sequencing would take actually a few days, or up to two or three weeks before we can be certain. We will be doing more tests on this virus and we are also working with the Hong Kong University on this.

H5N1 On Hong Kong Farm
Recombinomics Commentary 11:55
December 9, 2008
"We have discovered up to 60 dead chickens in that farm. After a series of tests we have confirmed this morning that the chickens did die from the H5 virus," health secretary York Chow told reporters.
The above comments strongly suggest that the confirmed H5 on the farm in Hong Kong will be H5N1. Hong Kong has strict control measures which keep H5N1 out of farms, and this is first case in six years.
However, H5N1 is detected in wild birds in Hong Kong at this time of year. In past years bird conservation groups have tried to link the annual outbreaks to religious ceremony release of birds, but in the past few years the outbreaks have been too early in the season to link to religious groups (and prior linkages were simply based on pure speculation, although the speculation was widely distributed by ProMED).
Recently, sequences from last years outbreak were released. The H5N1 was the Fujian strain (clade 2.3), but some isolates were clade 2.3.4 while others had a clade 2.3.2 HA and clade 2.3.4 for other genes. This reassortant subsequently appeared in the spring of this year in whooper swans in northern Japan, as well as outbreaks in South Korea and southeastern Russia, firmly linking the Hong Kong outbreaks to migratory birds and defining transport along the East Asian flyway.
However, this season the H5N1 in Hong Kong could be clade 0, which was detected in a fecal sample at the Qinghai Lake Nature Reserve this summer.
Release of sequence data from the Hong Kong outbreak would be useful. India has also reported a massive outbreak in Assam, which has been attributed to wild birds, and that outbreak is also early in the season, which may be signaling continued record outbreaks as seen in India, Bangladesh, and South Korea in the 2007/2008 season.

Hong Kong H5N1 Alert Raises Vaccine Concerns
Recombinomics Commentary 13:15
December 9, 2008
Hong Kong last had an outbreak on a farm in February 2003, showing the Government's prevention measures have generally been working well. However, Dr Chow said he is very concerned about the factors leading to this new outbreak as the first chickens to die were those which had not been vaccinated. The incident is being investigated.
The above comments from the Hong Kong alert raise concerns over the vaccine status of the H5 fatal infections of 60 chickens on a Hong Kong farm. Hong Kong had a major outbreak in 1997, which lead to human fatalities, and after a series of poultry outbreaks, instituted strict controls. Consequently, there have been no reported H5N1 outbreaks on farms in Hong Kong since 2003.
However, H5N1 in wild birds in Hong Kong has been reported at this time of the year for the past several years, raising concerns of a significant H5N1 reservoir, which has been kept off Hong Kong farms due to protective measures, which includes vaccination.
Consequently, the death of 60 chickens has led to the culling of over 80,000 and has raised vaccine concerns. There have been outbreaks in adjacent Guangdong Province, and concerns about failed vaccinations were also raised.
The earlier outbreaks in wild birds involved the Fujian strain (clade 2.3), which included clade 2.3.4 and 2.3.4/2.3.2 reassortants. Clade 2.3.2/2.3.4 reassortants were also identified last spring in northern Japan, Southeast Russia, and South Korea. The South Korean outbreak was the largest reported to date and included a symptomatic soldier/culler who was H5 PCR confirmed. Similarly, earlier Guangdong outbreaks were also linked to human cases in Shenzhen in 2006 or a case in 2008.
Thus, the latest outbreak in Hong Kong, which is almost certainly H5N1, raises additional vaccine issues and human infections in the area. Similarly, these outbreaks in the Hong Kong regions also raise concerns about the lack of reports of H5N1 infections in China.

Yuen Kwok-yung: vaccine failure is not surprising
。 He said Hong Kong had been detected in wild birds and chicken stalls in the market samples of the bird flu gene is H5NI, but the vaccine in Hong Kong in 2001, the use of H5N2, it is also not surprising that failure to start the vaccine。
He suggested that the Government discuss with the mainland authorities in Hong Kong can follow the example of the use of the Mainland H5NI vaccine to prevent bird.
