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

    Singapore to Stockpile Bird Flu Vaccine

    http://afludiary.blogspot.com/2010/0...u-vaccine.html

    Quote from afludiary.blogspot.com
    THE Health Ministry will be buying about one million doses of H5N1 avian flu pre-pandemic vaccine soon.

    The World Health Organisation's director-general, Dr Margaret Chan, had recently said that countries remain ill-prepared for mass outbreaks of the bird flu virus, which affects humans in contact with sick birds.

    It has a mortality rate of more than 60 per cent, leading to fears that a pandemic with this strain of virus could prove lethal. Scientists also fear that it could achieve efficient human-to-human transmission at any time and trigger a pandemic.

    Avian Influenza A (H5N1) in Humans: Lessons from Egypt

    Quote from www.eurosurveillance.org
    ...in the group of the 20-39-year-olds, women had a greater tendency to be infected and more women died post infection. Fifteen of 21 infected women in this age group died. These groups face the highest risk of exposure as it is mainly they who are involved in home slaughtering and defeathering of chicken and preparation of food, farm work and visits to infected farms. A recent study has analysed the age and sex bias with regards to the situation in Egypt [4], and it has been reported that farmers from other infected African countries believe that there is little or no risk of infection from culling, defeathering, home slaughtering and visit to infected premises [8,9]. In addition, failure of the government to pay compensation in Egypt for culled birds and the practice of keeping of poultry on rooftops and in close association with humans may have played a role. Although no association has yet been established between the level of exposure to avian influenza A(H5N1) and fatalities in Egypt, reports on workers in Asia showed that a high prevalence of infection in the poultry population is associated with a higher incidence of infection in humans, and that controlling such outbreaks of H5N1 influenza in the poultry flocks can stop human infection [7,10,11]. In addition, genetic characterisation of viruses from both the human and avian populations in Asia revealed that the viruses from both species were very similar [9,10].

    According to our analysis, early hospitalisation following infection increased the chances of recovery. Children tend to be hospitalised earlier than adults and this may have contributed to the significantly lower death rate in the children (only two cases in children under the age of 10 years were fatal). Similarly, although 62 of the 85 cases were under 19 year-olds, this does not represent national demography since only approximately 32% of the population are 15 years and younger [12]. In most parts of Africa, people are known to visit a hospital less frequently as they advance in age, and supposedly non life-threatening conditions such as seasonal influenza are often treated at home and therefore underreported [8].

    The overall case fatality in this study was 32% (27/85). This percentage may appear small when compared with statistics from other places, for example 82% in Indonesia (115/141), 68% in Thailand (17/25), 66% in China (25/38) and 50% in Vietnam (56/111). Nevertheless, with the exceptional surge in number of cases (especially in children) arising in Egypt in 2009 and the recent reoccurrence of human cases of avian influenza A(H5N1) in China and Vietnam despite an intensive control programme in the poultry populations, the pandemic potential of this virus is still very evident. Case fatality was significantly higher in females compared with males, but whether this is related to exposure dose can not be confirmed in this analysis.

    Indonesia: Residents Worry Over Poultry Deaths

    http://afludiary.blogspot.com/2010/0...r-poultry.html

    Quote from afludiary.blogspot.com
    Residents in South Lampung are panicking following the sudden deaths of thousands of chickens owned by poultry company PT Central Avian Pertiwi, despite the birds having been previously cleared of avian flu.

    However, after samples were re-tested at the Lampung Livestock and Animal Husbandry Agency lab, they were tested positive for H5N1.

    The egg-laying hens, totaling more than 12,000, have currently been culled and tens of thousands of others have been isolated.

    Indonesia: Changes in the H5N1 Virus

    This is a discussion on the controversial but widespread practice of using vaccines to protect poultry from H5N1. The consequences of this practice are becoming more apparent. The results are potentially dangerous for all of us. Read the full commentary at the link to understand why this is a cause for concern.

    Quote from afludiary.blogspot.com
    Poultry vaccination against the H5N1 bird flu virus has been the subject of considerable debate over the years, with many scientists warning that the the overuse of vaccines could backfire.

    Vaccination, it is feared, could hide the infection and allow it to silently spread, and may actually drive the evolution of the virus.

    For developing countries with poverty and food insecurity issues, however, vaccination is often considered preferable to wholesale culling.

    In Avian influenza and vaccination: what is the scientific recommendation?, the OIE reiterates their strong recommendation that humane culling be employed to control avian influenza, and advising that vaccines should only be used as a temporary measure.

    cambodia: h5n1 outbreak in ducks?

    Quote from crofsblogs.typepad.com
    via the phnom penh post: fowl play: takeo orders destruction of ducks. ducks are known carriers of h5n1, but it doesn't always kill them--or even make them sick. so this outbreak is of interest.

    the takeo province agriculture office has ordered the farmers of domesticated ducks across the province to incinerate their birds and temporarily suspended the sale of the animals’ meat until the results tests for the h5n1 virus (also known as bird flu), come back from phnom penh this week following mass deaths of the fowl.

    thai ly, takeo province’s chief officer of domesticated animals, said that 16,442 ducks had died since the outbreak began, and that roughly 31,000 more have fallen sick.

    Indonesia: A Bad Month for Bird Flu

    http://crofsblogs.typepad.com/h5n1/2...-bird-flu.html

    Quote from crofsblogs.typepad.com

    About 2,751 chickens had died of bird flu virus within previous month in Riau. This has folded the number of bird flu cases in chicken by 600 percent compare to number at same period of last year outbreak, 441 chickens.

    Head of Livestock Service of Riau Province, Patrianov said massive chickens deaths had been reported from six municipals/cities in Riau: Kampar 1,995 chickens; Siak 351, Indragiri Hilir 234, Indragiri Hulu 128, Rokan Hulu 22, and Pekanbaru 14. The shift of rainy season had influenced the replication of the virus.

    Several areas in Riau were still drowned by flood which had increased the rate of virus spread, added Patrianov. In the days of flood, people had trouble to diminish or bury dead chickens, so they preferred to dispose the chicken’s body to flowing water or puddle around their residences.

    Quote from www.thehimalayantimes.com
    Detection of bird flu in Pokhara has spread panic in the Lake City. Ministry for Agriculture and Cooperatives, in a press meet held in Kathmandu today, stated that ducks and chickens were dying in Pokhara due to bird flu and a high alert has been sounded in Pokhara and the surrounding areas.

    They had to be sent to London as there were no facilities for such tests in Kathmandu. Spokesperson for the ministry, Dr Hari Dahal, stated that the preliminary report of the tests showed that the ducks and chickens had died due to bird flu (H5N1 virus). Dr Dahal said the Rapid Response Team had begun its task to curb the spread of the disease in the affected area. Claiming that the flu would be controlled within seven days,

    ...the police had already stopped the movement of birds in and out of Pokhara and security personnel had been deployed on major highways and roads connecting Pokhara with other parts of the nation.

    Many migratory birds come to Pokhara, increasing the threat of bird flu. District Veterinary Office has assured the poultry entrepreneurs that the disease can be prevented if proper measures are adopted.

    media report: two more bird flu cases in egypt

    Quote from http://afludiary.blogspot.com
    if confirmed, this would make the 7th case reported in 2010, getting egypt off to a fast start in the new year. last year, egypt reported a total of 39 cases (4 deaths). the year before, just 8 cases (4 fatalities).

    machine translations into english, whether from arabic, chinese, or any other language, can sometimes be difficult to decipher. nuances and details don’t always survive the translation process.

    which is why i use them only cautiously, accepting the fact that some of the details may be `muddy’ or inaccurate. still, they have been a valuable tool as well watch disease activity around the world.

    we are fortunate, therefore, to have twall - a moderator at flutrackers - who lives in egypt, is fluent in arabic, and who offers this clarification:

    this group of words (التاميفلو المقاوم للمرض ) really means that tamiflu is used to treat the diseases of bird flu.
    it also reads like they were forced to transfer the person because of how sick they were.
