H5N1, Bird Flu Updates - page 19

Tracking Bird Flu Cases Bird flu deserves its own thread for tracking suspected and confirmed cases. It's not the pandemic virus, but it is still an ongoing and significant threat because of its virulence. As Margaret Chan,... Read More

    Sittwe, Burma


    Quote from www.narinjara.com
    Sittwe: Over 1,000 chickens have been culled in Sittwe Township in Arakan State after a tough strain of H5N1 virus was detected at a poultry farm, officials and a witness report.

    A witness said, "Many chickens from around ten poultry farms in Tae Chaung Village were culled on Monday. The culling was conducted by the health department. I'd guess over 1,000 chickens were killed by the authority."

    The authority has culled chickens from many poultry farms in Bumay Village Tract that are located around one kilometer from the original affected farm.

    South Korea


    Quote from www.arirang.co.kr
    A state of emergency has been declared on Tuesday here in Korea as bird flu continues to spread.

    According to the agriculture ministry, the flu is spreading rapidly throughout South Jeolla and Gyeonggi provinces.

    As preventive measures, chicken and ducks within a three-kilometer radius of the affected farms will be put down, and sales of these animals will be banned in traditional markets starting Thursday until the 27th of this month.

    Quote from arkanoidlegent.blogspot.com
    There were 23 new outbreaks of H5N1 highly pathogenic avian influenza (HPAI), across the western side of the country, particularly in the far south-west.

    The authorities sent Follow Up Report No. 4 dated 17 January to the World Organisation for Animal Health (OIE).

    All outbreaks reported were on farms and started between 6 and 13 January. Most were on ducks farms in the regions of Jeollabuk-do (North Jeolla), Chungcheongnam-do (South Chungcheong) and Gyeonggi-do."

    Lampung, and West Java, Indonesia


    Quote from birdflucorner.wordpress.com
    Kalianda Desa (village) Sidomakmur, Kecamatan (sub-district) Way Panji in Lampung Province stated as bird flu endemic area after 17 chickens and 4 swans had suddenly died. Confirmation was done through rapid test by Livestock Service.

    Indramayu Livestock Service (Distankan) stated fifty percent of Kabupaten Indramayu, West Java province, as bird flu endemic area.

    The disease is feared to spread among birds during rainy season. According to 2011 data of Distankan Kabupaten Indramayu, of 31 sub-districts, 18 are bird flu endemic. The endemic status was made based on the bird death data.

    As I read this, I was remembering that every living pig was culled in Egypt because of swine flu, and milions of birds have been exterminated because of bird flu in the affected areas

    The Koreans have been especially thorough in culling all living animals whenever H5N1, avian influenza hit regions of their country. It does not surprise me that the cullers would suffer emotional trauma from mass extermination of animals and birds. It must be truly terrible to be involved in so much killing, and to bury these animals alive...Is it possible to kill thousands of animals in a humane way?

    Quote from crofsblogs.typepad.com
    Via The Korea Times, a disturbing report: Quarantine officials mentally traumatized. While the story deals with culling pigs and cattle, I suspect the same effects are experienced by those destroying poultry in Korea's latest B2B H5N1 outbreak: Excerpt:

    Nearly 70 percent of government officials, who participated in the slaughter or the live burial of animals on farms infected with foot-and-mouth disease (FMD), are suffering severe mental trauma, a survey showed Friday.

    The results came amid soaring criticism that quarantine officials have buried hundreds of thousands of cows and pigs alive. The authorities explained the inhumane action was inevitable with the spread of the disease outpacing the authorities’ slaughter capacity before a proper burial.

    Japan Escalates Bird Flu Battle

    We are talking millions of birds at risk. Such an incredible waste if they must be destroyed...


    Quote from afludiary.blogspot.com
    After the discovery of H5N1 at a second Miyazaki Prefecture poultry farm over the weekend (see sidebar news item), the decision has been made to cull another 400,000 birds in a bid to contain the virus.

    The number of chickens within these quarantine zones varies depending upon the news source. Estimates run anywhere from 1.5 million to 4 million birds.

    As Japan battles this latest outbreak, the Hong Kong government has announced the immediate suspension of the processing of applications for the import of poultry and poultry products from Japan.

    EID Journal: H5N1 Branching Out


    Quote from afludiary.blogspot.com
    In the relatively short history of the H5N1 bird flu virus, the huge bird die off in 2005 at Qinghai lake was a watershed moment. Up until then, the H5N1 virus had been pretty much limited to southeast Asia; Hong Kong, Vietnam, Thailand, Laos, and China.

    But suddenly, and unexpectedly, we learned that waterfowl (brown headed gulls, cormorants, ducks, geese, etc.) – species that normally carry avian flu viruses with little ill effect – had died by the thousands at Qinghai lake.

    Something had obviously changed with the virus.

    And over the next 18 months, this new clade managed to spread widely – likely on the wings of migratory birds - across Asia, and into Europe and Africa.

    Experts warn avian flu could persist in Japan


    Actually, I don't know why they seemed surprised by the possibility of birds flying south to Japan.

    This is the 5th outbreak in two months, and 150,000 birds will be culled.

    Quote from www.asahi.com
    So far, highly pathogenic viruses were believed to be brought to Japan by migratory birds arriving in early spring from Southeast Asia, where bird flu is widespread.

    But after a highly pathogenic H5N1 strain, closely connected to one found in Mongolia, was detected in wild duck droppings in Hokkaido last October, experts started to suspect northern routes of infection.

    "There is a possibility that migratory birds infected in Russia and elsewhere are flying south (to Japan)," said Koichi Otsuki, an avian flu expert at Kyoto Sangyo University.

    The Bird Flu Situation in Egypt

    For those of you who are not aware the Egyptian Government cut off all internet access into and out of Egypt because of the civil unrest two days ago (link). This means that there are no news reports on suspected bird flu cases nor is the official Egypt Ministry of Health site on line. see http://www.mohp.gov.eg/

    The 122nd human case of bird flu in Egypt was reported on January 26 (link). Egypt now only lags Indonesia in the number of human infections among all of the world's countries. Right now we are in the middle of "bird flu" season in Egypt.

    The lack of timely health information and information on bird flu infections from Egypt is a grave public concern for people all over the world.

    H5N1 S227R In 2011 Whooper Swan In Hokkaido Japan


    Some acquisitions of H5N1 increase concerns about the possibility of transmission of the virus to humans in Japan, but given the severity of the culling in both Japan and Korea, I am thinking this will not go anywhere though we could see some cullers have positive cultures. It is also likely that they would be be protected with prophylactic Tamiflu. I don't think that they would allow any chance of human to human spread.

    With that said, if the environment, (such as the water) is contaminated in the areas where wild birds are bringing the virus in, what can they do about that?

    Quote from www.recombinomics.com
    A 2011 H5N1 sequence, A/whooper swan/Hokkaido/4/2011, has been released by Hokkaido University at Genbank. The sequence is clade 2.3.2, as expected, but it has the receptor binding domain change S227R.

    In 2005, the acquisition of S227N by clade 2.2 was predicted, based recombination between donor sequences in H9N2 in the Middle East and Qinghai H5N1. The ability of H5N1 with S227N to bind to human receptors led to the prediction of human cases in the Middle East, which was confirmed in the sequence from the index cases in Turkey in 2006. S227N was in two of the four human sequences in Turkey and appeared in subsequent human H5N1 sequences in Egypt.
