    US invokes emergency act to keep H7N9 flu at bay

    THE US government has declared that H7N9 bird flu "poses a significant potential for a public health emergency", and has given "emergency use authorisation" for diagnostic kits for the virus. This means tests can be used that haven't gone through the usual lengthy approval process by the US Food and Drug Administration.

    They are right to be concerned. H7N9 could be a tough adversary: New Scientist has learned that it provokes a weaker immune response than most flu, making vaccines hard to produce.

    Although H7N9 is not, so far, transmissible between humans, it does cause severe disease in people, is easier to catch than other bird flu strains, and may need only a few mutations to go pandemic. The UK has already given doctors instructions on when to test people for H7N9, and how to manage any with the virus.

    The US's emergency authorisation will allow the use of a kit that looks for flu genes using a polymerase chain reaction test, which has been made specific for H7N9. The kit has had preliminary tests but would normally need more exhaustive tests to be approved. Innovative new diagnostics should eventually be authorised too, says Charles Chiu of the University of California in San Francisco.

    This kind of fast, high-throughput screening for pandemic flu, possibly at borders, might allow early cases to be treated with antiviral drugs, potentially slowing the spread of the virus while vaccines are made.

    The next emergency authorisation is likely to be for immune-stimulating chemicals called adjuvants to put in those vaccines. These were used in vaccines in Europe and Canada during the 2009 pandemic, but adjuvants suitable for flu are not currently approved in the US.

    Labs are now making "seed" viruses for manufacturers to create H7N9 vaccine. That process faces the same development delays as in 2009, when vaccine arrived too late for most people.

    But there is another problem: H7 flu is poor at stimulating immunity. Virologists at the European Flu Summit in Brussels last week told New Scientist that early results show 13 times more H7N9 virus is needed to elicit a protective immune response than is needed for ordinary flu. That's bad news: the more virus a vaccine requires, the fewer doses that can be grown in a given time.

    "H7N9 may be a 'stealth' virus that is able to fly under the immune system's radar," says Anne De Groot of the University of Rhode Island at Providence. That's because its surface protein haemagglutinin doesn't contain many short amino acid sequences – called epitopes – that trigger helper T-cells in the body to stimulate antibody-making cells.

    "H7N9 is not very immunogenic, because the epitopes have a very weak signal," says Masato Tashiro, head of flu at Japan's National Institute of Infectious Diseases in Tokyo. People differ genetically in the epitopes their T-cells recognise, and his lab has found that Asian people could be especially vulnerable.

    Adjuvants might make vaccines containing less virus more effective, meaning doses can be produced faster. However, children in northern Europe who received adjuvanted flu vaccines in 2009 had slightly higher rates of narcolepsy than normal. Epidemiological studies so far do not show whether the adjuvant was the cause, says Miriam Sturkenboom of Erasmus Medical Center in Rotterdam, the Netherlands. The US is now funding a large study of countries that used adjuvanted vaccines in 2009 to see if they may have caused narcolepsy.

    Since it doesn't pass from human to human, then,
    I guess that we should stay away from birds?

    Abby, is this the thread you were looking for? http://www.braintalkcommunities.org/...7-NEW-Bird-Flu I thought I'd copy the link so all the info you posted is in one place.

    There is more news but I am not going to be the one to pull the alarm this time

    I don't think any alarms are being sounded. I found this from the US Centers for Disease Control:

    http://www.cdc.gov/flu/avianflu/h7n9-faq.htm#new-strain

    They're saying that there is a danger of a pandemic, and it could spread from person to person, and it could be picked up from eating contaminated poultry but they're also saying that as of now, the risk in the US is low.

    Apparently it's not fatal but it causes serious illness.

    Out of a population of 1.35 Billion people, 126 cases of this bird flu were identified in China from the end of March to the end of April. Shanghai, the "hardest hit city," had 33 cases out of a population of 23 Million people. These statistics support the CDC's statement that "human infections with bird flu are rare."

    The CDC also states: "So far, hundreds of close contacts have been checked, and there has not been any evidence of ongoing spread of this virus from person-to-person."

    This was just published today in Forbes ~ Shanghai Ends H7N9 Bird Flu Measures; Poultry Shares Gain:

    http://www.forbes.com/sites/russellf...hares-recover/

    Yesterday, this article was published in Live Science, stating that the H7N9 Bird Flu cases are declining, and no cases have been seen in the U.S.:

    http://www.livescience.com/29515-bir...e-decline.html

    Remember the Swine Flu? Whatever happened to that? My son was in ICU for 45 days during that outbreak, and not one case of Swine Flu was admitted while he was there. However, the yellow carts popped up in front of many rooms, indicating isolation due to MRSA, C-Diff, hospital acquired pneumonia, etc. By the time my son was discharged, the Swine Flu was ancient history.

    Since I never plan to visit China, and I'm a vegetarian, so I'm never near poultry, I don't think I will worry about H7N9. But, I will continue to worry about MRSA and new Superbugs, as well as the seemingly endless new strains of human flu, all of which present growing, serious threats worldwide.

    Eat nutritious food (accent on fruits and vegetables, grains, nuts and seeds ) and wash your hands regularly. Those are probably our best defenses against most viruses.

    I visited your links. The first one to Bloomberg is dated 4/27. The second link to Fox News is dated 4/22. The third link to the Daily Mail pertains to genetically modified foods, and I'm not sure how that connects to H7N9.

    To alleviate your fears about H7N9, I did a little more Googling today.

    I found an article, published today (5/12) in Medical Daily, which states that an 83 year old woman died from H7N9 in Shanghai on Friday. She was infected a month ago.

    No new human infections of H7N9 have been reported in the past 20 days, which is equivalent to 3 incubation periods for H7N9.

    Additionally, 458 people, who had close contact with the infected individuals have been released from observation, showing no signs of infection.

    http://www.medicaldaily.com/articles...uthorities.htm

    From the current news articles about H7N9, it appears that the concern about this virus is over. To me, the fears of an epidemic or pandemic may have been an overreaction on the part of the media at the first outbreak of H7N9.

    An infection in 126 people out of a population of 1.35 Billion people is minuscule.

    This virus seems to have been isolated to China, related to the handling of live poultry, not transmissible human-to-human, and over within a month. As with all flu viruses, people did die, and likely they were elderly, as the woman mentioned in the article, or were immune compromised.

    I think we're okay now, and we don't need to worry about this flu virus. Another one will come along in due time, unfortunately. At this point, let's just be glad that H7N9 has run its course.

    And, who knows? Maybe scientists and researchers learned something from it, which will be valuable in treating other existing or future viruses. We can hope.
