I knew one of these days that it would make it back to Hong Kong, after all it is where it all started back in 1997.
During current year several wild birds were discovered dead or positive for bird flu H5N1 virus. It is a predictable event, for this reason HK SAR has in place a surveillance system working all the year, with inspection, sampling, ''rest days'' with deep cleansing activities and more other.
One could only hope that this system is able to avoid a disaster like that in 1997.

4. Serious Response Level depicts two possible scenarios. The first
scenario depicts confirmation of HPAI outbreaks in the environment of or
among poultry population in retail markets, wholesale markets or farms in
Hong Kong due to a strain with known human health impact. Upon the
advice of DAFC or Director of Food and Environmental Hygiene, SFH will
activate this Response Level.
5. The second scenario depicts the confirmation of human case(s) of
avian influenza in Hong Kong without evidence of efficient human-tohuman
transmission. Upon the advice of DoH, SFH will activate this

Hong Kong markets higher risk of human transmission of avian flu
[大纪元June 8 - (Associated Press reported Linyi Hong Kong) Hong Kong Government on June 7 in a market that confirmed H5N1 bird flu virus case, immediately ban the mainland live chickens to Hong Kong three weeks to trace bird Sense of the source. Microbiology experts have said that the incident reflected the avian flu virus increase the risk of human transmission.
Government security, Cheung Sha Wan Road Market 3 chicken vendors in the faecal samples of chickens found the deadly H5N1 bird flu virus immediately after the destruction of the market within nine chicken stalls in a total of 2,700 live chickens, and announced that since the June 9 ban for mainland live chickens in Hong Kong on the 21st, while contingency measures will be upgraded to serious by the alert level. This is Hong Kong since 2002, once again post-mortem samples from the market to the H5N1 avian flu virus.
Chinese University of Hong Kong Department of Microbiology, said Professor Chen Jixiang, the markets found that the avian flu virus is a very strong warning, reflecting the avian flu virus increase the risk of human transmission, "because in chickens in the markets are very dense, so if a virus, usually There will be many chickens will be infected, the virus will be the number of many. There are many other markets and the public will have close contact with birds, chickens infected, pass the relatively high, relatively we fly Bird, chicken bar or find a chicken farm, that a more recent threat to the public. "
Chen Jixiang and pointed out that the chickens have not developed symptoms appear, such as the hidden infection, difficult to find, more threatening.
Chen Jixiang, said: "After the vaccination of chickens will be protected, but there is a situation that is, the chickens were infected, it no symptoms, but also very vigorous, but it is likely that the special stool in the row will have a virus, the virus Will pass near the chickens. Therefore, such as the hidden infection is relatively refractory, because the hidden infection more difficult to be found, hidden in people infected with the more threatening, but also the relatively Refractory . "
He also pointed out that: "If this is a hidden infection of chickens with the virus that may be but no one knows, although the virus to chickens did not pose a problem, but if the viruses to people, we must as a very serious Disease, because now H5N1 spread to humans at high risk of. "
Chen Jixiang do not think that the current vaccine in chickens on the failure, but the effect of a vaccine, there are some complicated factors: "If you do not fight because of the vaccine, if there are varieties of H5N1 in chickens, the chickens will be in The outbreak caused great, great time of the outbreak, the virus is usually the number will be many, many infected with the virus the opportunity to major. Vaccines to fight the outbreak of the reduction, but do not know which chickens on the virus, because it no symptoms Therefore, they are very complex issue. "
Chen Jixiang said that this incident once again proves that central slaughtering is to prevent the outbreak of avian flu and the fundamental approach.

Dr Chow does not deny that there are problems chickens believed to have sold considerable quantities, but yet to find cases of human infection of bird flu, in his view the public as long as the chicken thoroughly cooked, the risk will not be great. Mainland authorities have been informed immediately to the epidemic, Hong Kong has been the strain of avian flu alert level raised to the level of serious strain. He stressed that as long as more than a re-confirmed bird flu case, we will slaughter of chickens in Hong Kong. Information, on a territory-wide slaughter of chickens is 02.
As for the avian chickens come from, Dr Chow said, could not identify the source, which may involve local or mainland farms, does not rule out the smuggling of chickens, but said, the problem is only chickens from the Cheung Sha Wan Temporary Wholesale Poultry Market in five Wholesalers, the authorities are tracing the source, but has no intention of Cheung Sha Wan market closed.

The outbreak of chicken three kilometers markets sell explosive epidemic control as the implementation of this clean, did not kill 70,000 chickens June 9, 2008
Excerpt:
[Ming Pao Daily News - The government has not yet been identified Sham Shui Po On Road Market is a local chicken farms, bird, the import or smuggling of chicken, but only ordered the "infected areas" chicken stalls in the market nine Maiji suspended 21 days,Chicken stalls in the vicinity yesterday will continue to bulk cargo, even bare hands catching chicken customers a high-risk scenes. Administration will start this afternoon chicken stalls in the Rest Day "by knife slaughter of chickens", Hong Kong markets will sell the surplus of about 70,000 chickens culled, but the wholesale markets selling live chickens left in 4000, can still be continued tomorrow subscription.
The government earlier announced a bird flu epidemic explosion "of regional control policies", sets out three km radius of the outbreak within the scope of "prohibited area" to the chicken is prohibited 90 days, but the authorities deal with the security Road in downtown chicken stalls in the epidemic, Only the "prohibited area" to narrow the scope of security Road Market, within a radius of three kilometers of the Tsz Wan Shan, Sham , Kowloon City and Yau Tsim Mong area, or even from the very recent outbreak of the Cheung Sha Wan Temporary Wholesale Poultry Market, the same as yesterday Maiji be business as usual, falls far short of epidemic prevention standards.
Senior officials: Guangdong farms used only for control of the epidemic explosion
AFCD Assistant Director of Veterinary Xuehan for this paper explained that the regional control policies apply only to temporary farm explosive epidemic in Guangdong Province, the local chicken stalls have been vaccinated chickens in bird flu vaccine and bio-security and a constant Regular sampling virus and antibodies to monitor, relatively low risk, I believe that these measures can reduce risk. He said that the security found in three chicken stalls, markets have chicken with avian flu, chicken stalls have not found abnormal chicken deaths or symptoms.
HKU Department of Microbiology, Yuen Kwok-yung, the scope of the outbreak area, the ideal is immediately suspended the sale of live chickens, but the bird incident should not "systemic crash," most likely is the problem of smuggling of chicken, measuring risk , To allow the sale of chicken traders on the 1st yesterday and more chicken, the chicken slaughter rest today a comprehensive Clean, "is not too much," but he reiterated that the authorities must quickly implement central slaughtering chickens policy, can not be further delayed.
Lo Wing-lok: Maiji continue to ignore the risk
Communicable diseases Dr Lo Wing-lok criticized, is still unknown whether the chicken stalls in other markets without security epidemic, but to continue Maiji allow them, is extremely unreasonable and ignoring the risk of bird, more ironic is that the outbreak of chickens from the chicken stalls Cheung Sha Wan Wholesale Market, but the market yesterday continued scattered chickens and sell leftover chicken can be added on sale tomorrow, it is very dangerous.
Mong Kok stall owners: Napster ended March with 410,000 people smuggling selling chicken feet sources said cheap imports 20%
June 9, 2008
[Ming Pao - the avian flu reach our markets, many academics and the industry are attributed to the "smuggling of chicken", this reporter was then made to a number of market poultry stalls for traders in the markets in Mong Kok, the chicken stall operators Ms Chan admitted that criminals have repeatedly been lobbying purchased smuggling chickens, they told her that adequate supply of imported chickens in general bid was 20% cheaper, but each time refused to Ms Chan Hon.

Some industry sources, a few months ago, chicken smuggling is a serious problem. He said that two months ago, customs and the department in Tuen Mun and Yuen Long area containing the intercepted 12 containers of chicken smuggling. He believes that the smuggling of chicken with the market price of chicken as legitimate, it difficult to distinguish between the public, but the profit is three times the legal chicken. General lawless elements from Shekou of Shenzhen into the chicken, then chicken to wholesalers, retailers may also be so innocent, but when the reporter asked again and wholesalers the situation when he was reluctant to say more and more to Mobile phone power shortage because demand interrupted dialogue.
Scholars blasting materials suspected of involvement in smuggling of chicken disease

Hong Kong Poultry Wholesalers Association, president of Mission Xu said, the problem of smuggling of chicken there is often due to the import of live chickens is in short supply, only 30,000 daily, exploited by criminals and the smuggling of live chickens and chicken post, can be beneficial Fig.

FEHD in 2004-2007, the chicken stalls in markets found to have the H9 avian influenza virus samples rate, multiples also soaring, 04 and 05 by only 0.7% and 1.5%, 2.2 to 06 percent, while As of July last year of 12 months, as a ratio of 5.3 percent, microbiologists have warned that the data reflect the decline in the markets of live chickens immunity, once the highly pathogenic H5 virus, the more explosive epidemic crisis.
AFCD Assistant Director of Xue Han pointed out that the Administration was aware of the trend, and the data can be as an indicator, if the virus is higher, may consider stepping up cleansing and improve health. At present, there has been sent to Hong Kong farms blood samples taken from chickens, understand their antibody levels, and understand whether it has collected stool with avian flu virus, the wholesale market will also strengthen the sample tests.
Tracking the source of alleged flawed system
However, Agriculture and Fisheries Members of the Legislative Council questioned Wong Yung-kan, the current system of tracking the source of live chickens is imperfect, markets burst epidemic fundamental points less than the local scene or the chicken, just "broad-brush" full ban, which has seriously affected the operations of industries . He said authorities may refer to the "quality of local fish" approach, coupled with chicken feet in the Central and includes code for tracking. However, the live chicken retailers that this law unreasonable, unless the provisions of local and mainland chickens kept separate cages, otherwise difficile sources.

Bird flu fears recede in Hong Kong as markets are given all-clear
Jun 9, 2008, 11:03 GMT
Hong Kong - Fears of a bird flu outbreak in Hong Kong were receding Monday after tests on all markets in the city of 6.9 million failed to find further traces of the H5N1 virus.
The former British colony went on bird flu alert Saturday after swabs taken at a market in the Shamshuipo district found traces of the virus that led to a deadly outbreak in Hong Kong 11 years ago.
The market was closed down, chickens from mainland China were banned and tests were ordered on all poultry markets in the city, a move which saw the sales of chickens plunge 30 per cent Sunday.
However, the government announced Monday that no traces of the virus had been found at any other market in the city or in farms in Hong Kong or in southern China.
Assistant director for agriculture Thomas Sit said investigations into the source of the virus were continuing and customs officers were checking if affected chickens were smuggled into Hong Kong.
Workers in face masks and protective suits Saturday killed 2,700 chickens at an infected market in a chilling reminder of the bird culls in the city in the 1990s.
Hong Kong was home to the first modern case of bird flu to jump the species barrier and infect humans in 1997 when the H5N1 virus killed six people and infected 12 others.
Since then, thanks largely to stringent checks and mass culls when any cases are discovered, there have been no further cases of humans infected by bird flu in Hong Kong despite regional outbreaks.
Expert Warns Hong Kong Poultry Measures Inadequate
Posted on: Monday, 9 June 2008, 06:00 CDT
Text of report by Radio TV Hong Kong Radio 3 on 9 June
[Newsreader] Chicken traders have been given a temporary reprieve by the government and allowed to sell their remaining livestock - instead of culling them - after the bird flu virus was found in a local market. As Altis Wong reports, the traders were in a last- minute rush to try and sell their stock ahead of the monthly wet market clean-up which began at noon today [0400 gmt].
[Wong] The market clean-up day has been brought forward following the discovery of the H5N1 virus in three stalls in the Po On market in Sham Shui Po on Saturday [7 June]. All chicken traders have been asked to cull all their stocks to prepare for the clean-up. Some of them complained about the rescheduling of the cleansing day, which is usually slated for Wednesdays. The government has imposed a halt on chicken imports for 21 days in a bid to stop the spread of bird flu.
[Newsreader] Yesterday some 2,700 chickens were slaughtered at a market in Tsim Sha Tsui where sick birds were found. But an infectious-disease expert, Dr Lo Wing-lok, said the government action was too late.
[Lo] The government has deferred the control measures by two days by continuing to allow poultry sales in the retail market, in the wet markets [i.e. of live poultry] without at the same time knowing that the poultry on sale in the retail markets are safe. I believe that the measures are inadequate and may cause the virus to spread in the community.
The three local farms which supply chickens to Po On Road Market and Cheung Sha Wan Temporary Wholesale Poultry Market have been confirmed avian flu-free, Assistant Director of Agriculture, Fisheries & Conservation Dr Thomas Sit says.
He told reporters today Mainland authorities have confirmed chickens at six Mainland farms are normal.For local retail markets he said tests are underway, with some samples confirmed free of avian flu.
On chickens at Cheung Sha Wan Temporary Wholesale Poultry Market Dr Sit said they will be released after tests on all samples are confirmed to be virus free, adding test results may be available tonight.
Assistant Director of Food & Environmental Hygiene Chu Lan-ying said the ventilation system at Po On Road Market has been operating smoothly and cleaning will be arranged.
The Food & Health Bureau said Saturday's chicken cull was necessary to safeguard public health and curb the virus spread. Noting the move has affected the live poultry trade, the bureau will consider compensation requests.
Government responds on avian influenza case June 9 2008, 13.52.50
In light of the presence of H5N1 avian influenza virus in environmental samples taken from Po On Road Market in Sham Shui Po during regular surveillance earlier, the Government has adopted special measures promptly to protect public health, a spokesman for the Food and Health Bureau said today (June 9).
"We understand the measures introduced would have some impact on the traders and we have received their request for compensation.
The Government will consider the traders' request before taking a decision later," the spokesman said.
The detection of avian influenza virus in Po On Road Market showed that the existing surveillance system has been working effectively to allow the Government to eliminate the virus, cleanse the markets and trace the source of the virus promptly so that the threat of the virus could be minimised, the spokesman added.
In addition, the Agriculture, Fisheries and Conservation Department (AFCD) and the Food and Environment Hygiene Department (FEHD) have been actively tracing the source of avian influenza virus found in the Po On Road Market.
From the invoices of the three affected stalls, FEHD staff have traced back to the wholesalers, then traced further so far to three local farms and six mainland registered farms which supply chickens to Hong Kong.
According to AFCD, there was no abnormality in the three local farms that supply chickens to the wholesalers involved.
The six Mainland registered farms were checked and so far the Mainland inspection and quarantine authorities confirmed that there were no abnormalities.
FEHD had sent staff to Mainland registered farms and processing plants with the aim to ascertain that chickens and poultry meat for supply to Hong Kong would not be affected.
There was an allegation that the Government had taken a long time to make public the test results of the environmental samples from the Po On Road Market.
The spokesman explained that the treatment of environmental samples was different from dead birds.
Under the regular surveillance, virus isolation was used to test environmental samples and this took at least a few days.
The environmental samples were taken on June 3 and the results were announced on June 7.
We understand that the time taken by AFCD to test the samples was comparable to the time required by the local tertiary institutions when conducting similar tests.
The spokesman pointed out that all legal live chicken imports and local chickens from registered farms had to undergo random checks before entering the Cheung Sha Wan Temporary Wholesale Poultry Market.
Only those with satisfactory test results were allowed to be sold to retailers.
Emphasising that the Government had all along been sparing no effort in cracking down on illegal import of live poultry and birds, the spokesman said the Government would not tolerate illegal chicken imports which pose threats to public health.
The Customs and Excise Department together with the relevant departments would conduct a comprehensive special investigation and step up actions to deter smuggling activities.
The Customs and Excise Department called on members of the trade and the public to report any smuggling of poultry and any intelligence to the Customs Information Hotline 2545 6182.

Dr. Niman,
I know that the clade in Indonesia is different, than the one in China. I still keep remembering this news. When they say "mixing with the other virus" could the clades combine? Is their any connection here between Indo & China poultry?
