in 1999 over 400 million people. From the history of mankind, the only 20th century,http://www.simu001.cn]addontv.it/]hogan sito ufficiale], there have been three times the worldwide influenza pandemic: in 1918, 1957, 1968. Where in 1918 - 1919 that the most serious. This flu,http://www.simu001.cn]infosite.it/stivali-hogan/]stivali hogan], also known as the Spanish flu, because the Spanish media and public attention and the name, but in fact spread to most parts of the world, and it took more than a year,http://www.simu001.cn]culligansmartsensor.fr/]moncler veste], 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,http://www.simu001.cn]infosite.it/hogan-interactive-donna/]hogan interactive donna], but they are still slightly different, not the same strain that caused too much harm. This by far the largest human influenza origin has been controversial. But one thing is now certain: That the virus is likely to be, first spread in animals,http://www.simu001.cn]mywe.it/]hogan rebel], after variation, gain the ability to spread from person to person,http://www.simu001.cn]siasprint.it/scarpe-hogan-outlet/]scarpe hogan outlet], and interpersonal communication,http://www.simu001.cn]infosite.it/hogan-olympia-donna/]hogan olympia donna], 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.this one, called "virus." It is human, has long been entangled. This is only a hundred years,http://www.simu001.cn]quvi.it/]scarpe hogan], a hundred million people were killed there in 1918 the Spanish flu pandemic in 2009, including women and children, "a flow", and China has reported dozens of cases of this yesterday,http://www.simu001.cn]akura.it/]hogan online 2015], "H7N9". This is what exactly? Why it seems every few years will come about? Variation in the end how it happened? How does it spread? Compared to "H several N a few" how to name, perhaps the public is more concerned about: we can not really get it right? Why would always vulnerable to attack? Is it possible to completely "inside Iraq so special (Shanghai dialect, meaning: kill)"? Well-known science society "scientific squirrel" authors, and experts with friends, to the newspaper provided a science report. In addition to the known.
pension system between Europe and America. Multi-level and market-oriented system to meet the different needs of various groups, they have their place, no problem. From this perspective, the United States of pension as an integral part of the national governance system of play is positive energy,http://www.simu001.cn]becatendevarese.it/]hogan scarpe], enhance the country's competitiveness,http://www.simu001.cn]vrouwentellen.nl/category/parajumper-jas/]parajumper jas], for China,http://www.simu001.cn]vrouwentellen.nl/category/parajumpers-winkels/]parajumpers winkels], in particular, is worth learning.? (The author is director of the Institute of American Studies Chinese Academy of Social Sciences& Nbsp; & nbsp; & nbsp; text / Ho Po spend Ge Jun Hao Ran Integration / reporter Liang JiangangThere are all kinds of poison in the world.
they said a lot of unknown. The beginning of the report, is a called the most "pit father" of the name in history. It is known: influenza, and usually cold, are two completely different disease Unknown: 1918 flu virus,http://www.simu001.cn]elbrellin.it/hogan-prezzi/]hogan prezzi], whether to pass people from the bird Bird flu's full name, is a "bird avian influenza,http://www.simu001.cn]spot2013.nl/category/pjs-jassen/]pjs jassen]," it simply is suffering from bird flu. Not yet directly observed, the spread of bird flu among humans, but the virus can sometimes spread to birds in direct contact with people or animals,http://www.simu001.cn]spot2013.nl/category/parajumpers-jas-dames/]parajumpers jas dames], diffusion. 1997 Hong Kong emerged H5N1, resulting in 18 people infected, six people were killed, it is the case. Human bird flu had, in essence simply belong died of a flu. But in fact, the flu and ordinary flu (seasonal influenza), are two completely different disease! Apart from some initial onset of symptoms similar outside source and trigger the symptoms of these two diseases, 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.
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", that is, the four influenza virus, the most powerful "Influenza" Unknown: from H1N1 to H7N9,http://www.simu001.cn]enotecheregionalipiemonte.it/hogan-napoli/]hogan napoli], 170 kinds of combinations of pandemic influenza virus,http://www.simu001.cn]elbrellin.it/hogan-outlet-on-line/]hogan outlet on line], 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), 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, the above is also like a hedgehog, there are several processes. We also know that these types of models, the most powerful is the "alpha." Influenza A viruses can infect humans, 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, 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,http://www.simu001.cn]criminal-minds.it/hogan-scarpe-uomo-amazon/]hogan scarpe uomo amazon], 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, numbered H1 to H17, which last two --H16 was found in 2004.
