,hogan rebel uomo<p> transmission and susceptible populations, are indispensable. So we usually do not have to worry too much about. Just reduce exposure, to maintain good health habits,hogan sneakers, the chances of infection is much smaller. In the fight against the virus, the current human development out of the main treatment is to try to block the intrusion of certain aspects of the virus, thereby inhibiting the virus reproduction.</p>
<p> gain the ability to spread among the population, the consequences could be disastrous. Therefore, the culling of poultry infected with bird flu, it is possible to reduce the probability of human infection with avian influenza. In 1997 the Government will be in 3 days, millions of poultry culled in Hong Kong, although a bit extreme, but many experts believe that is the case only effectively prevents outbreaks worldwide. Currently, Shanghai closed all poultry market practices, in theory,hogan on line, is also useful. Another particularly close watch on the pigs. The study found that both the bird flu virus or human influenza viruses,scarpe hogan outlet online, pigs can be infected with,hogan outlet, and could they be "training" very well - it was a good place in the middle of the recombinant variation. Therefore, from this perspective, it is not recommended for large-scale pig and poultry farmers plant too close to the plant planning. In fact, the emergence of early 2009 H1N1 virus, on a mix of swine flu and avian flu genes from the human influenza virus. So, the virus mutation and evolution, what is the mechanism? Still unknown. It is known: influenza virus thermal stability is poor, as temperatures rise in the future, the time their survival will become shorter Unknown: Currently on the mode of transmission of influenza, not a thorough understanding of the situation and some non-airborne also difficult to explain Currently.</p>
<p> constantly, "beyond recognition." Again only learn these new variations. The probability of survival of the virus, thereby increasing. Human risk of illness, therefore increased. And there is evidence that the virus protein molecule that is recognized by the immune system,hogan, the variation faster than other parts. The role of the immune system also seems to accelerate their rate of change, eliminate even harder. In addition to the high mutation rate, a recombinant influenza virus among different species,hogan donna 2015, but also to make it easy variation. Current knowledge, the influenza virus genome distributed on eight RNA chain. If someone also infected the body of two or more viruses, restructuring it may occur at any time, such as H1N1 H2N3 might encounter after swaps, in theory, the formation of H1N3, H2N1 and other new subtypes. At the same time, infectious and pathogenic virus gene exchange may also occur, the virus becomes more weak,hogan donna, or, worse, become more powerful ... This is why now,hogan sito ufficiale, when the outbreak of avian flu, we become nervous. Especially when a human or other animal was infected with bird surprise, possibly in the infected host body, there are other influenza viruses (such as a human influenza virus infection who,hogan spaccio, just another bird flu), then In the event of restructuring variation, you can make the bird flu virus from a human influenza virus there.</p>
<p> in the fight against the flu virus in humans is still only on the defensive,hogan outlet online, but the situation is not very optimistic. Even, the current mode of transmission of influenza to understand it is not very thorough. A typical mode of transmission of influenza, through coughing and sneezing release of the virus, spread through the air; but the situation is somewhat non-airborne, it is difficult to explain. Preventive measures being announced, wear a mask or reduce exposure to birds,scarpe hogan, to a certain extent, can help to prevent avian flu. However, some people go to destroy the nest or something on the extreme, after all, carry the bird flu virus is in the minority. And if the bird should be ruthless, then pigs,hogan scarpe, dogs,hogan scarpe 2015, cats, these may be potential carriers do the same? In addition, poor thermal stability of influenza virus. With temperatures rising in the future, the sun's ultraviolet enhanced time they can survive in the environment, will be shorter and shorter, the spread of power will diminish. As ordinary citizens, we should know that the spread of infectious diseases must meet three factors: the source of infection.</p>
<p> So in the face of influenza virus, human This "intricate" animals, indeed should remain vigilant heart. Humans have immune system against the disease,hogan donna outlet, then usually too sick,hogan scontate, the body will remember, and generate resistance, so the possibility of a second suffering from the same disease, it is very low. Influenza can be chosen is an exception. Influenza virus is special in that it is recognized that part of the immune system, often silently produce a change, if you can evade the immune system to kill the memory and general - Most people infected with the flu in the next few years, will The new generation of variant strains, once again lose resistance. The reason for this, is the influenza specific genetic way. We, including all plants and animals, genetic material is called a double helix molecular structure of DNA, the above carrying the "genetic code." The two share mutual supervision,scarpe hogan outlet, to ensure that genetic information is accurate. But the genetic material of influenza viruses,hogan donna, but it is worse than the stability of DNA "RNA molecule." Coupled with the influenza RNA during replication to the next generation, there is a very "bad" helper --RNA polymerase, so the next generation of newly synthesized RNA, often wrong. This is like a group of students careless text transcriptions, after numerous transcribed, and the resulting article had and text sweeps clean. This is the accumulation of the virus to mutate. This can be hard on the immune system. Originally had in mind to destroy the object.</p>
