    <p> the above is also like a hedgehog,outlet hogan italia, there are several processes. We also know that these types of models, the most powerful is the "alpha." Influenza A viruses can infect humans,hogan online outlet, other mammals and birds, the most prone to mutation, the root causes of major influenza pandemic is a few times. Influenza A viruses are the largest family,hogan rebel, it is divided into several different subtypes, usually written several N H a few (a few changes in the figures). H and N mainly depicted are some of the characteristics of the virus surface projections. Like pattern on the special clothes, scientists rely on these "patterns" to give virus collation. So we saw a few N H a few saying that it refers to a certain type of influenza virus. Specifically: - "H", the English initials hemagglutinin. Currently known 17 kinds (subtypes) of influenza hemagglutinin, according to human discovery order of time,hogan online outlet, numbered H1 to H17, which last two --H16 was found in 2004,hogan outlet online, only carry influenza from Sweden and Norway and other countries Black-headed Gull flu detected; H17 is 2012 found in fruit bats in; - "N", is in alphabetical neuraminidase. It is wrapped in the shell of the virus another substance that can help the virus is released from the host cell. You know - this is an important step in the virus invades cells. Currently,outlet hogan, humans detected neuraminidase total 10 kinds. Therefore, such a calculation, influenza virus,scarpe hogan scontate, in theory,hogan bambino, could have 17 multiplied by 10 kinds of combinations, that is, 170 kinds, and each is different. So there was no so-called H7N9 is an upgraded version of the H1N1 he said. But such a large portfolio, indeed completely overcome human influenza virus,hogan world, causing great difficulties. However, "the suffering of sadness" that the actual species far less than this figure,hogan milano, a lot of combination type.</p>

    <p> first spread in animals, after variation, gain the ability to spread from person to person,hogan online, and interpersonal communication,scarpe uomo hogan, the toxicity was enhanced once again, that has caused such serious consequences. In other words, the virus, really fickle; and it transformed much borne. In 2007, scientists have used the 1918 H1N1 strain to infect monkeys, monkeys in just a few days, then died. Blood immune proteins, reached a very high level. Thus informed that this virus, the immune system attacks the organism, so that the other high-load operation or even "overload", thereby detonating vivo "immune factors storm", resulting in patient death. This is the description from the pathology, and how this virus will poison, and why such a terrible flu powerful. Once the immune system collapse, as did the castle moat, not a computer "firewall." But we still unknown how this virus production. Known: who called "H several N a few",calzature hogan, that is, the four influenza virus, the most powerful "Influenza" Unknown: from H1N1 to H7N9,jas parajumpers, 170 kinds of combinations of pandemic influenza virus, and exactly how the ever-changing We know that this virus long-sawed. Currently, people under the inherent characteristics of the virus, will all find the human influenza virus, divided into A (A),scarpe hogan uomo, B (B), propyl (C) III. These viruses are the size of 10 to 300 nanometers (a nanometer is one billionth of a meter) in pellets or fibrous, surface membrane.</p>

    <p> are not the same. Influenza virus infection, often have systemic symptoms, and fever. If the flu when treating the common cold, it is more likely to lead to serious consequences. Therefore, the body cold symptoms occur, can judge for themselves what so preliminary. If the symptoms are very obvious, do not "carrying", it is best to go to the hospital. World Health Organization survey figures show: global deaths due to influenza each year 250 000 -50 million, in 1999 over 400 million people. From the history of mankind, the only 20th century,parajumpers jas dames, there have been three times the worldwide influenza pandemic: in 1918,hogan store, 1957, 1968. Where in 1918 - 1919 that the most serious. This flu, also known as the Spanish flu, because the Spanish media and public attention and the name,hogan prezzi, but in fact spread to most parts of the world, and it took more than a year, 50 million and 100 million people were killed, a heavy blow to the global political and economic. It was also said that this flu, the real reason is to promote "a war" ended. 1918 pandemic caused by pathogens, later determined to be H1N1, which is a global pandemic of 2009 H1N1 flu the same, but they are still slightly different, not the same strain, the harm caused is far greater. This by far the largest human influenza origin has been controversial. But one thing is now certain: That the virus is likely to be.</p>
