    Of Ducks, Feathers, and H5N1

    Of Ducks, And Feathers, And H5N1

    Quote from afludiary.blogspot.com
    Ducks and other aquatic birds are a major reservoir of the H5N1 virus, with some species capable of carrying the pathogen without ill effect. H5N1 is generally a gastrointestinal malady in birds, and the belief is that the virus is usually spread via infected feces.

    In 2006, however, we became aware of a cluster of human H5N1 infections (7 cases, 4 fatalities) in Azerbaijan which were ultimately linked to the harvesting of feathers from dead swans.


    And more recently, in June of this year, we saw a study (see Birds Of A Feather . . . .) in PLoS One, suggesting that waterfowl may be acquiring and spreading avian flu viruses because their preening oils bind the virus to their feathers.

    ...the H5N1 virus may persist on the dropped feathers from infected ducks and that they may spread the virus to the environment.

    Study: What Makes Avian Flu So Deadly

    Quote from afludiary.blogspot.com
    Avian flu, particularly H5N1, has our attention because unlike regular influenza, it has a very high mortality rate. Among those we know to have been infected, roughly 60% have died.

    A rate well over 100 times higher than with regular flu.

    Apoptosis is programmed cellular death, while Scribble is a protein the body’s immune system uses to promote the early death (apoptosis) of virally infected cells.

    In this way, the immune system can help limit viral replication while it develops defenses (antibodies, cytokines, etc.) against the invader.

    In the case of H5N1, the virus’s PDZ binding-motif works to deactivates the host’s apoptosis defense mechanism, giving the virus a decided advantage.

    cairo, egypt - case #112

    h5n1: egypt: a new case of human h5n1

    if she is not responding to tamiflu, let us hope that they will use relenza or peramivir for this unfortunate woman. as we all know by now, the adult cases in egypt frequently do not survive but the toddlers do. and, we have to ask, why is the tamiflu not working?
    was she treated too late or is this strain of h5n1 tamiflu resistant (which is always a hugh concern)?

    Quote from crofsblogs.typepad.com
    the patient, a female resident of the qalyubiya governorate, is currently receiving treatment at a cairo hospital.
    according to a ministry statement, her symptoms include high fever and breathing difficulties. she contracted the illness after coming into contact with poultry suspected of having been infected with the virus, the statement noted, adding that she remained in critical condition despite having been treated with the anti-viral drug tamiflu on arrival to the hospital.

    the last time an egyptian succumbed to the h5n1 virus was in april. that case brought the total number of bird flu fatalities in egypt to 34.

    Ferreting Out the Transmissibility of H5N1

    Quote from afludiary.blogspot.com
    One of the (many) unanswered questions about H5N1 avian flu is why it doesn't more easily infect humans and why is human-to-human transmission so rare?

    We think we know part of the reason:

    Avian adapted influenza viruses bind preferentially to Alpha 2,3 receptor cells, which are commonly found in the digestive tract of birds. This explains why most avian flu viruses are gastrointestinal infections in birds.

    Human adapted viruses have an affinity for the alpha 2,6 receptor cell, which populate the upper airway and lungs. This is why influenza is a respiratory virus in humans.

    But of course, we've got at least 500 exceptions to the rule. H5N1 does, on rare occasion, find a home in a human host.

    Indonesia: Two New Reports

    Two New Reports Out Of Indonesia

    Quote from afludiary.blogspot.com
    Getting bird flu news out of Indonesia can be particularly difficult since the Health Ministry decided several years ago that constantly talking about their H5N1 problem was bad for the country's image (see Indonesia To Stop Announcing Bird Flu Deaths).

    Today Ida has two stories.

    First, the suspected Bird Flu infection of a young girl in West Kalimantan, which if you will recall, was the location of a suspected bird flu fatality in July...

    A second report details steps that are being taken in Luwu Timur, South Sulawesi to try to combat an outbreak of H5N1 in domestic birds, where thousands of birds have recently died.

    In response, the Health Service has formed a special avian influenza treatment unit in anticipation of possible human cases.

    This story also suggests that standard control measures in Luwu Timur, such as the spraying of disinfectant, have failed to control the outbreak.

    Spain: H5 Avian Flu In Doves

    I am having a little problem understanding how and why this happened. The virus is a highly pathogenic avian influenza (HPAI), and an H5. Highly pathogenic means a high mortality rate.

    Is it H5N1, "the bird flu" of Egypt, Indonesia, Vietnam, China and Cambodia or another virus? They are not saying. It would be useful to know as humans are at risk if it is H5N1.

    The normal host of avian flu viruses are ducks, and other water birds. Doves are not the usual victims of this virus. Chickens that have become infected have a high mortality rate if they become infected. They make great victims. Doves, though, kind of unusual to hear of this...Btw, pidgeons are a type of dove, rock doves specifically. I seem to remember that as another name for the common pidgeon.

    Quote from afludiary.blogspot.com
    Pigeons, however - which are of the same bird family (Columbidae) - have gotten somewhat more attention over the past few years, partially because they (and their feces) are so ubiquitous in many population centers.

    Around the world, opinions vary over the threat these city dwellers present. In Bangladesh pigeons, along with ducks and chickens, are routinely culled in their fight against bird flu.

    The good news is, since we haven't seen more than a few pigeon or dove related bird flu stories over the years, the evidence is scant that they pose much of a health threat to humans.

    Of course, the H5N1 virus is constantly changing and evolving, and so that assessment could change in the future.

    Russia - Virus killed 1000+ birds in Krasnoyarsk lake - FluTrackers

    Quote from www.flutrackers.com
    machinetranslated

    Unknown virus in Krasnoyarsk lake killed 500 birds

    KRASNOYARSK, September 20. On the shore of Lake Tagar in the Krasnoyarsk Territory ornithologists found dead migratory birds.

    Among the dead birds - ducks (mallard, Cherokee, shelohvost) and crows. According EMERCOM Russia in Krasnoyarsk region, only found about 500 animals.

    In connection with the emergency on the lake and 100-meter zone of sanitary quarantine. 2 posts were put up DPS and get information boards. Moreover, in Minusinsk District banned the hunting passes Ngs.ru

    Causes of death of the birds are being investigated. Presumably, the death of the birds could occur as a result of acute viral disease. In this regard, there are already several reports on the return of bird flu.

    south sulawesi, and east java, indonesia

    first we have this story:

    a bad week for indonesian chickens

    Quote from afludiary.blogspot.com
    malili - avian influenza or bird flu h5n1 attacked kabupaten (municipal) luwu timur, south sulawesi. at least twenty-four thousand birds in nine sub-districts, kecamatan wotu, burau, tomoni, mangkutana, tomoni timur, kalaena, malili, angkona and wasuponda had been infected.

    so far, the virus is not transmitted to human.
    and now this one:

    watching indonesia again

    Quote from afludiary.blogspot.com

    the newshounds on flutrackers are watching reports out of indonesia today on 8 people with flu-like symptoms in the region (pinrang) where thousands of chickens recently died from the h5n1 bird flu (see a bad week for indonesian chickens).

    reports like these usually end up being something other than bird flu - since seasonal flu, along with many other illnesses - can produce similar symptoms.

    still, human cases and even clusters have occurred in indonesia in the past, and so reports like these are taken seriously by local health officials and are watched closely by the rest of the world.

    The Ongoing Bird Flu Flap in Indonesia

    The Ongoing Bird Flu Flap In Indonesia

    Quote from afludiary.blogspot.com
    The situation in Indonesia over night appears to be evolving, but `into what' isn't easy to say.

    The headline - if it can be trusted - is that the number of people being `monitored' with flu-like symptoms in the area where thousands of birds have recently died has grown to 18.

    But exactly what criteria is being used to decide who to monitor, and how seriously ill any-or-all of them are is difficult to determine.

    Hong Kong - 59 year old woman infected with bird flu

    For those of you concerned about H5N1, a press release today


    Press Release



    Woman infected with H5 in serious condition
    *******************************************
    The serious response level under the Government's Preparedness Plan for influenza pandemic was today (November 17) activated as the Centre for Health Protection (CHP) of the Department of Health (DH) investigated a case of influenza a H5 infection affecting a 59-year-old woman.

    The patient developed running nose since November 2 and fever and cough on November 5. She sought medical attention from the Accident and Emergency Department of Tuen Mun Hospital (TMH) on November 12. On November 14, she was admitted to TMH for persistent fever and productive cough with blood-stained sputum. She was diagnosed to have pneumonia and is now in serious condition.

    A spokesman for the CHP said that the nasopharyngeal aspirate taken from the woman tested positive for Influenza A (H5). Further studies on the virus were in progress.

    Investigation revealed that the patient travelled to the Mainland with her husband and daughter between October 23 and November 1, during which she did not have any contact with live poultry contact and had not visited farms.

    Her 60-year-old husband had history of running nose and productive cough but has recovered.

    "The CHP has stepped up surveillance by testing all severe pneumonia cases for H5," the spokesman said. The serious response level under the Government's Preparedness Plan for influenza pandemic has been activated. A telephone hotline 2125 1111 has been set up to answer public enquiries.

    "The CHP is also closely liaising with the Mainland authorities and the Hospital Authority to monitor the situation."

    He advised members of the public that the best way to combat influenza infection was to build up body resistance by having a proper diet with adequate exercise and rest.

    "Good ventilation should be maintained to avoid the spread of respiratory tract infection.

    "Members of the public should seek medical consultation promptly if they develop influenza-like illness.

    "Members of the public should also avoid direct contact with poultry and birds, and if contacts have been made, they should wash hands thoroughly with soap and water," the spokesman said.
