    agoH7N9 bird flu spreads much like ordinary fluBy Maggie Fox, Senior Writer, NBC News

    The H7N9 bird flu can spread from one mammal to another – meaning it could also spread person to person, an international team of researchers reported Thursday.


    Researchers haven’t been exactly sure how H7N9 is spreading. They know it can infect people – it’s infected more than 130 people and killed more than 30 of them – but they have suspected most of the victims had some sort of contact with infected poultry.

    The research team, led by Yi Guan of the University of Hong Kong, tried infecting ferrets – the animals closest to humans when it comes to catching flu.

    The animals could infect one another by direct contact in cages. And one ferret kept in a separate cage was infected as well, they report in this week’s issue of the journal Science.

    “Under appropriate conditions human-to-human transmission of the H7N9 virus may be possible,” they wrote.

    Dr. Anthony Fauci, director of the U.S. National Institute of Allergy and Infectious Diseases, says he is not too worried by the findings. “We already know you can infect mammals,” said Fauci, who was not involved in the research.

    “That is what influenza does. We know that. You are talking about a handful of ferrets. You can’t make major extrapolations.”

    Officials are keeping a close eye on H7N9 because it has the potential to cause a human pandemic. So far, it doesn’t seem to infect people easily and people who are infected do not seem to spread it to others much, if at all. But influenza viruses change quickly and unpredictably and if one starts passing easily from one person to another, it could spread.

    The experiment also showed that the ferrets could pass the infection before they started showing symptoms. Human flu does this too – that’s why it spreads so quickly and easily every year, because people are out and about, touching others, before they know they are sick.

    “If this virus acquires the ability to efficiently transmit from human-to-human, extensive spread of this virus may be inevitable, as quarantine measures will lag behind its spread,” the researchers wrote in Science.

    “Assuming that poultry is the source of the H7N9 virus, continued prevalence of this virus could lead to it becoming endemic in poultry as has occurred with the Asian highly pathogenic H5N1 and H9N2 virus lineages," they added. Endemic viruses are established and cause constant outbreaks.

    "If so, the opportunities for the H7N9 virus to evolve to acquire human-to-human transmissibility, or to be introduced to pigs, would greatly increase. To prevent this happening, it may be advisable to reconsider the management of live poultry markets, especially in the urban areas.”

    New H7N9 infections appear to have trailed off in China. World Health Organization officials say it might be because officials are closing poultry markets and cleaning them. Or it could be because it’s spring and influenza tends to die down in the spring.

    Marc-Alain Widdowson of the U.S. Centers for Disease Control and Prevention says the virus doesn’t make poultry sick, so it could spread quietly and easily.

    “One thing that we are particularly worried about is there is a tremendous amount of poultry that goes from China into Vietnam,” said Widdowson, who visited China with a CDC team to investigate the outbreak.

    “One of the things we are looking at is ramping up surveillance in bird markers and in the population.”

    People who buy an infected chicken won’t know, because H7N9 doesn’t make the birds sick they way H5N1 does, Widdowson says. “It worries me substantially,” he said.

    “There’s absolutely no doubt it has got some very concerning mutations which suggest it may be adapting to human receptors. These make it closer to what we are all fearing, which is a virus that can spread sustainably humans to human and cause severe disease.”

    The New Bird Flu Will Spread More Easily Among Humans Than Other Bird Flu Strains
    Jennifer Welsh | May 23, 2013

    A girl, who was previously infected with the H7N9 bird flu virus, waves as she is being transferred to a public ward from the ICU at Ditan hospital in Beijing, April 15, 2013.
    Close contact with someone infected with the new bird flu strain, H7N9, is likely to get you sick, according to a new study published today, May 23, in the journal Science.

    The virus isn't that great at passing through the air, though, so in order to contract the virus you would need to stand and talk with the sick person for about 15 minutes.

    Currently, 131 people have gotten sick with the new virus, and 36 have died. Hong Kong researchers are guessing that 90 to 120 more cases could exist, though cases have slowed in recent weeks.

    "This study was designed to give us clues about the transmission of H7N9 which has affected some humans in China," study researcher David Kelvin, of the University of Toronto, said in a statement.

    That study included infecting ferrets with the virus in the lab. They use ferrets as the animal model for human flus because they are mammals like us, they get the same viruses, and they show symptoms of the infection.

    They also tested the virus on pigs, because they are often incubators for influenza viruses. It didn't pass between them as well as it did in the ferrets, though.

    "The animals used in the study had very mild clinical symptoms as a result of their exposure to the virus and it was clear that very close contact was required for transmission. It also appears that this virus in its present form does not transmit very well through the air."

    Scientists are worried that it could mutate and gain that ability, since it's already more evolutionarily adapted to spread among humans than other bird flus they've seen. They've already started seeing changes to the molecules on the outside of the virus that control how it enters cells, according to NPR's Shots blog.

    "These findings suggest that the novel virus had been evolving and might, with a few amino acid mutations, adapt to humans," write the authors of the report in the New England Journal of Medicine, published May 22.

    These "stepwise" adaptations — where small mutations happen over time — are similar to the way the 1918 and 1957 flu viruses adapted and caused pandemics. These mutations happen as the virus lingers in animal populations. Though there are fewer new human cases, the virus needs to be wiped off the face of the Earth, and quickly.

    "There's a bit of a worry in my mind that the urgency to do something about this will drop," study researcher Richard Webby, of St. Jude Children's Hospital and the Word Health Organization, told Shots. "We really need to get on top of this virus and get it out of animal populations. Otherwise it's just not going to go away."

    I would stay away from crowds (even though they have not gone public with the human to human YET) stock up on flu meds (beat the rush) and lots of surgical makk ans gloves I have some clorex wipes whixh I am using for door knobs and stuff get some water and food put back for an emergency in case of worse case.
    I'm feeling better and better about spending the vbg bucks on this IQ Air filter

    Just use good sense do some planning and not worry about it. thats what I am doing but to do nothing is really stupid!

    get some water and food put back for an emergency in case of worse case.
    Very good idea anyway even without flu to worry about.

    In earthquake areas like the one I live in, people are advised to do this. That's a lot of water to store if you don't have much space, and so I haven't been good about storing water. I used to keep it on hand but sometimes the plastic containers spontaneously broke, and space was a problem.

    I always try to have enough food on hand to get through several days even if it's mainly peanut butter and crackers.

    Anyone have suggestions about types of food that are good for storing? Canned goods, pasta, rice?

    ((((((Abby & All Concerned))))))

    After a little Google scouting for information, I discovered some reassurance about the H7N9 bird flu.

    Isolated to China
    No new cases since May 8, 2013
    Contracted by living in the habitat of/or handling wild and domestic birds, as well as live poultry
    Not transmitted human to human


    A Centers for Disease Control (CDC) Graphic explaining the Genetic Evolution of H7N9 Flu in China:

    http://www.cdc.gov/flu/images/avianf...nt-diagram.jpg

    The people, who contracted H7N9 flu in China, acquired the flu by sharing the habitats of wild and domestic birds, and/or in live bird/poultry markets.



    The CDC tested two antiviral medications, Tamiflu and Relenza, which are used for seasonal flu, against the H7N9 virus, and these medications were effective in treating H7N9:

    http://www.flu.gov/about_the_flu/current_flu/index.html



    The World Health Organization (WHO) update on H7N9 (dated May 17, 2013):

    http://www.who.int/csr/don/2013_05_17/en/index.html

    No new H7N9 cases have been reported to WHO since May 8, 2013. The WHO states: "So far, there is no evidence of sustained human-to-human transmission."


    Neither the CDC nor WHO have recommended restrictions on travel to China, because of H7N9.




    Seasonal Flu Facts:

    1. Annual percentage of U.S. population (over 3 million people) who will get the seasonal flu: 5 - 20%

    2. Annual average number of persons in U.S. hospitalized with seasonal flu: 20,000

    3. Annual number of people in U.S., who die from seasonal flu: 3,000 - 49,000

    http://www.webmd.com/cold-and-flu/flu-statistics


    H7N9 infected 131 people in China, with a population of 1.5 Billion people. About 36 of those infected people died. Thus far, it doesn't appear to be transmitted by human to human contact.

    In the study of H7N9 with ferrets and pigs, it appeared that the transmission required close contact, the symptoms in the animals were very mild, ferrets passed the virus better than pigs, and airborne transmission of H7N9 isn't easy.

    The seasonal flu is far more concerning, given the number of deaths from it annually, and that it is contagious and highly transmissible between humans.

    Scientists are studying H7N9 in an effort to eradicate it from birds/poultry. It would seem that if they can prevent birds from getting it, humans will have less reason to worry about it affecting us.

    Like any flu virus, our best defense is washing our hands frequently, avoiding crowds during flu season (usually reaches its peak in January and February), eating nutritiously, taking Vitamins, and getting proper rest and sleep. With H7N9, the best thing we probably can do is avoid handling live birds or buying food at a live poultry market. Another reason why I am happy to be a vegetarian.

    Its only a airplane ride away ar all rimes.

    There is a cheaper way ro stock up but its a bit harder to do

    You go to bakeries at grocery stores ask for thie old icing buckets (usually they just throw them awau) yoi clean them out buy big bags of rice/beans etc and some dried ice fill them up and put dried ice in to kill bugs ( just a small piece of ice will do) and then you lay the top of pail on top for awhile before you seal it.
    Buyine organic would br optium ,

    Then buy the cream of this and that soups - only problem with this is to have to cook that rice and if you can't the dried rice comes in handy - then theres learning how to cook in a thermos

    Life will change and we will have to adapr and make do

    Hundreds of people infected with H7N9 as virus continues to spread - Is a real flu pandemic on the horizon?
    Tuesday, May 28, 2013 by: Jonathan Benson, staff writer


    http://www.naturalnews.com/040510_H7..._pandemic.html



    (NaturalNews) The ongoing spread of H7N9 avian flu across Asia could be much more serious than the mainstream media is currently leading on, as some reports now suggest that the actual number of infections and deaths may be at least double what is being reported. Researchers from the University of Hong Kong (UHK) say there could already be as many as 120 adults with H7N9 that are flying under the radar due to milder infections that have not yet been detected.

    As of last month, the World Health Organization (WHO) is reporting 109 confirmed cases of H7N9 infection and 22 deaths from the disease. The majority of infections have thus far emerged in Zhejiang, Shanghai, and Jiangsu, but the first confirmed case of H7N9 outside of China was recently identified in nearby Taiwan. And according to reports, the condition is striking primarily elderly males, with younger populations less susceptible to infection.

    But if you add another 120 mild cases of H7N9 to the mix, the overall number of infected individuals more than doubles to 229 cases. According to Benjamin Cowling, an associate professor at UHK's Public Health Research Center, this figure is likely more accurate than the official one, and there could even potentially be many more infections that have yet to emerge and be reported.

    "One thing that is very striking is the age distribution of the cases," says Cowling, as quoted by Bloomberg.com. "They're very different from the confirmed infections of H5N1," he adds, noting that H5N1 has mostly afflicted younger people in their 20s and 30s.

    You can monitor the spread of H7N9 using Bloomberg's graphic tracking module:
    http://www.bloomberg.com/infographic...-bird-flu.html


    People vaccinated with seasonal, H1N1 flu vaccines more susceptible to serious H7N9 infection
    With a current mortality rate of about 20 percent, H7N9 appears to be a particularly virulent flu that many health experts are concerned may lead to a pandemic. The infamous 1918 Spanish Flu, according to The New Yorker, is estimated to have killed as many as 100 million people worldwide in three deadly waves, and it only had a roughly two-percent mortality rate.

    "It could be that hundreds of other people have mild infections" with H7N9, says Tom Frieden, Director of the U.S. Centers for Disease Control and Prevention (CDC), confirmed the UHK researchers' assessment of the situation.

    But what is even more disturbing is the fact that people who have already been vaccinated for seasonal flu or H1N1 swine flu may be more susceptible to serious infection or death from H7N9, should they contract it, compared to those who have not been vaccinated. A paper recently published in the journal Eurosurveillance explains that flu vaccines can prevent neutralizing antibodies from recognizing new pathogens, resulting in weakened immunity and higher susceptibility to more serious infection.

    "Sometimes - and for reasons that aren't well understood - an earlier viral infection can set the host up for a more serious infection when exposed at a later date to a similar virus," explains the paper. "The problem usually comes later, when a person is infected with a different serotype," it adds, referring to closely-related, yet distinct, viruses that can cause more serious infection down the road.

    What this means, of course, is that all those people who rushed to their local flu clinics to get jabbed for H1N1 swine flu back in 2008 and following could be the ones most seriously affected by H7N9, should it spread globally.
