Wild bird found dead with H5 in HK shopping district

04 Jan 2007 10:16:22 GMT


HONG KONG, Jan 4 (Reuters) - A wild bird found dead in a shopping district in Hong Kong has tested positive for H5 avian influenza and government experts said on Thursday it might have been infected by migratory birds flocking south.

"Preliminary tests show H5 but we will make further tests to confirm ... if it's H5N1," said a government spokesman.

The munia was found dead along with five others in Causeway Bay district on New Year's Eve, but the others tested negative.

"This is a local bird. It is possible that migratory birds, while stopping here, could have come into contact with our local birds and infected them," said Thomas Sit, assistant director of the Agriculture, Fisheries and Conservation Department.

The H5N1 virus made its first known jump to humans in Hong Kong in 1997, killing six people. So far, it cannot be passed easily from human to human, but experts fear the virus could mutate and cause a pandemic, killing millions.

Fujian H5N1Bird Flu Spread to Hong Kong

Recombinomics Commentary
August 10, 2006

Earler this year there were reports of H5N1 bird flu in various wild birds in Hong Kong. Today the sequences of those isolates were released at Los Alamos. The released sequences were from poultry and wild bird isolates. All HA sequences were 98-99% identical with the Fujian strain of H5N1 which had been reported in patients in China in 2005 and 2006.

In addition, H5N1 sequences from Laos and Malaysia were also released earlier and those sequences were also closely related to the sequences from the patients in China. The HA sequence has a novel cleavage site which is missing a K. H5N1 sequences from China missing a K in the HA cleavage site have been reported since late 2003. These sequences have bee frequently found in Hunan and Fujian province as well as the quarantined birds in England.

However. most of these isolates have a slightly different gene sequence, although the sequence of the cleavage site is the same, RERRRKR. The Fujian bird isolate, A/Duck/Fujian/1734/05 however, has the genetic match for the human sequences. This genetic match is also in the sequences from Laos, Malaysia, and the newly deposited sequences from Hong Kong (see list below).

The widespread presence of the Fujian sequence in China, Hong Kong, and southeast Asia is cause for concern. New bird and human cases are being reported in Thailand, and bird outbreaks have recently been reported in Laos and Vietnam.

More information on the sequences of these isolates would be useful. Indonesia is also reporting new outbreaks in birds and humans. However, the human cases have a novel HA cleavage site, RESRRKKR, which does not match the Fujian sequence or any other public sequence, including the sequences deposited today from the lab in Australia,

Tests on dead bird in Hong Kong point to avian flu

HONG KONG (AFP) - Early results of tests being carried out on the carcass of a wild bird found in Hong Kong indicated it was infected with H5 avian influenza, the government has said.

Six carcasses of a local species of wild bird called scaly-breasted munia were found in the busy shopping area of Causeway Bay on Sunday.

Only one tested positive for the virus, but further tests were being conducted on all six, said Thomas Sit, assistant director of the agricultural department.

Sit said winter time was the migratory bird season, posing higher risks for bird flu.

"I suspect many animal health authorities around the world (believe) that migratory birds may be the first to carry the viruses," he said Thursday.

While he reminded the public to observe good personal hygiene, Sit said patrols around wet markets -- where the dead infected bird was found -- would be stepped up.

He urged local farmers, pet traders and owners to take necessary precautionary measures and avoid contact with wild birds.

Sit said inspections would also be stepped up in villages, where poultry might be kept. A curb on so-called backyard farming was enacted last year following the discovery of eight birds and chickens that had died of the H5N1 virus.

Hong Kong was the scene of the world's first reported major bird flu outbreak among humans in 1997, when six people died of the then unknown mutation of the avian flu virus

</TD></TR><TR><TD class=theme_text vAlign=top align=left>The Agriculture, Fisheries & Conservation Department has bolstered inspection and control measures against avian flu after one of six bird carcasses found on Leighton Road, Causeway Bay, tested positive for the H5 virus.

Assistant Director of Agriculture, Fisheries & Conservation Dr Thomas Sit told reporters today more tests are being conducted on the dead spotted munias collected on December 31. He expects results in the coming days.

As they are a wild bird residing in Hong Kong, they are more vulnerable to avian flu from January to March due to cross-contamination with migratory birds.

The department has enhanced checks on farms and pet shops, with no abnormal incidents observed so far. Farm and shop owners have been urged to be vigilant and adopt bio-security measures, while their workers should ensure good hygiene.

More measures
Meanwhile, inspection of imported poultry and market stalls will be strengthened, and doctors will be informed of the latest situation. They must notify the Centre for Health Protection of any suspected avian flu cases.

To stop people keeping backyard poultry, Dr Sit said a new round of village inspections will be conducted.

He called on the public to ensure good hygiene, avoiding contact with and feeding wild birds. People should wash their hands thoroughly.

Scaly-breasted Munias are among the most common Munias and are now quite common in Singapore too. They are found even in urban areas as well as cultivated lands, grasslands, scrub, secondary growth. But they were not so common in earlier records, suggesting that they could have been introduced.

Scaly-breasted Munias specialise in eating grass seeds and sedges, and have large conical beaks adapted for this purpose. They feed both on seeding heads on grass stems, as well as on ripe seeds that have fallen to the ground. They may also snack on small berries, such as those of the Lantana bush. Some have been seen picking at road kills.

Scaly-breasted Munias are highly gregarious and forage in small flocks, sometimes with other Munia species.[/FONT]

Hong Kong wild bird has H5N1 virus

Hong Kong (dpa) - A wild bird found dead in urban Hong Kong has tested positive for the avian flu virus, government officials confirmed Thursday.

The bird, discovered in Causeway Bay on Hong Kong island, is the first this winter to be discovered in Hong Kong with the virus which has killed 157 people mainly in Asia since 2003.

Dr Thomas Sit of the Agriculture, Fisheries and Conservation Department, said tests on the bird revealed it had died of the H5N1 virus and that it could signal the start of the bird flu season in Hong Kong.

"I would suspect, as would many animal health authorities in the world, that migratory birds may be the first to carry the virus and then infect wild birds," he said.

He said doctors had been asked to watch for possible human cases while his staff would step up monitoring of the wild bird population.

Re: Wild bird found dead with H5 in HK shopping district

None of the posted articles mentions that these birds were found in a wet market (i.e. a more likely source of infection than flocking with wild birds).

Furthermore, scaly-breasted munias are also a common cage bird sold in markets in other asian countries like Thailand (talked about in this article from scidev.net). Without detailed information on these birds (age, sex, molt, etc.) it would be hard to know for sure if they were even wild.

If anyone out there is in Hong Kong, it would be great if you could shed some light on whether munias are also common cage birds in HK.

Re: Wild bird found dead with H5 in HK shopping district

There is a wetmarket at Causeway Bay:

Causeway Bay

Bordered by Victoria Park, a typhoon shelter, the Hong Kong Stadium and the Royal Hong Kong Yacht Club, Causeway Bay is one of the busiest areas of Hong Kong by day or night. Modern department stores stand alongside open-air markets, cooked-food stalls, cinemas, bars and restaurants.

Hong Kong has many wet markets and if you have never been to one, you are in for a treat! Yes, all five of your senses will be activated! I personally like the one in Causeway Bay (near Times Square)

These are from wild birds and happen every year at this time in Hong Kong. The prime mover of H5N1 sequences is wild birds and the infection of these birds every year at this time has nothing to do with wet markets.

In 2003/2004 new sequences flew into Hong Kong that were not present in 2001. Wild birds transport the sequences, and recombimnation drives the evolution of H5N1 (via acquistion of polymorphisms from wild birds).

I think that they sell these finches at my local Petsmart. I thought it looked familiar. They say that they are not wild caught, but rather bred for sale. Looks like the same bird with the scaley breast.

H5N1 in Wild Bird in Hong Kong
Recombinomics Commentary
January 4, 2007

http://www.recombinomics.com/News/11090602/H5N1_RBD_Hunan.htmlDr Thomas Sit of the Agriculture, Fisheries and Conservation Department, said tests on the bird revealed it had died of the H5N1 virus and that it could signal the start of the bird flu season in Hong
Kong.

"I would suspect, as would many animal health authorities in the world, that migratory birds may be the first to carry the virus and then infect wild
birds," he said.


The above comments describe the first reported case of H5N1 in 2007. The finding was not unexpected. Each season migratory birds pass through Hong Kong at this time of the year, and H5N1 infected dead wild birds are typically found. Last year the birds were infected with the Fujian (Clade 2 sub clade 3) strain of H5N1, and similar findings would be expected, although the Qinghai strain has been reported in South Korea, so that strain may also be expanding to the south. In the recent PNAS report, only one Qinghai isolate was reported for southern China, but the limit detection was likely due to the source of the samples, which was largely limited to wet markets.

The new season will lead to new polymorphisms, as was seen in the human H5N1 isolate in Egypt. That isolate had M230I, which is adjacent to the receptor binding domain and is found in all three human serotypes (H1N1, H3N2, and influenza B). The new acquisition creates an exact match with positions 226-230 (QSGRI) in influenza B.

Recently, the largest cluster reported to date in Egypt was just 12 miles from the index case, suggesting M230I will also be present in that cluster. This would be a cause for concern because other changes in the receptor binding domain were found in Qinghai isolates from patients in Egypt (S227N), Turkey (S227N), Azerbaijan (N186K), and Iraq (N186S and Q196R). In addition V223I has been found in a bar-headed goose in Mongolia, and K222R was in a cat in Dagestan. Similarly A188E has been found in chickens in Lagos while A189E has been found in an ostrich in Nigeria. The chnages have also been found in H5N1 isolates in northern, and southern China, which link to migratory birds carrying the Qinghai strain.

Since all of these changes in or near the receptor binding domain in Qinghai isolates, which also has PB2 E627K, migration of these sequences into new regions are likely to cause new problems.

Hong Kong on Bird Flu Alert
Hong Kong was on bird flu alert Friday after a wild bird found in a busy shopping area was tested positive for the avian flu virus .

Officials confirmed Thursday that preliminary testing of a dead bird found in Causeway Bay had indicated it was suspected to have died of H5 avian influenza.

Further confirmatory tests are being conducted, but officials have stepped up monitoring and precautionary measures and advised doctors to be on the lookout for human cases.

The carcass of the Scaly-breasted Munia was one of six dead birds found in the same area.

A spokesperson for the agriculture, fisheries and conservation department said they would conduct a fresh round of visits to local poultry farms and pet bird shops to ensure precautionary measures against bird flu were in place.

"In view of this suspected case, we have phoned poultry farmers reminding them to maintain precautions against avian influenza. Letters have also been issued to the farmers, pet bird shop owners, licence holders of pet poultry and racing pigeons reminding them that proper precautions must be taken," he said.

"We will visit villages again to ensure that no poultry is being kept illegally."

This is the first case to be discovered in wild birds in Hong Kong since March last year.

Between Jan 10 and March 22 2006, 15 wild birds, one backyard chicken and a chicken smuggled from China tested positive for the virus.

However, no human cases were detected of the deadly virus, which according to the WHO has killed 157 people, mainly in Asia, since 2003.

Hong Kong has stringent precautionary measures in place to guard against an outbreak of bird flu since 1997 when the virus crossed the species barrier in the former British colony and infected 18 people, of which six died.

I can appreciate the fact that migratory birds may play a role in the dispersal of H5N1 to new locations; however, to outright dismiss the role of poultry density and importation, fomite contamination, and the wild bird trade with an offhand comment about wet markets having "nothing to do" with it is a bit flippant.

For example, nearly every year in the days leading up to the solstice, the importation of poultry into HK from the mainland doubles (check out the news report here). Hmmmm. That sort of got me thinking that, maybe, just maybe, there are some other logical, rational, and valid hypotheses about H5N1 vectors, that are based on something other than arm-waving.

The sequences are quite real and fly into Hong Kong each season.
