<p> it It will persist, as to become what, depends on its variation. " His research team next step is to continue to study,air max mujer, after which the virus can spread from person to person in the position of evolution, after the discovery on the implementation of tracking, make sure it has no evolutionary trend this talent. Who is susceptible? The law H7N9 virus to infect humans, seems in line with the general rules of conventional influenza. As of April 14,boutique louboutin, 51 cases of infection in people over age 50 account for 75%. But Cohen will star believes that because the sample is less, it can not determine who is susceptible, but he also acknowledged,veste moncler femme, H7N9 infection seems to follow the universal law of the flu. Via Over time, humans against different viral strains develop a lot of special proteins called antibodies,scarpe nike air max prezzo basso, each antibody will involve infection suffered in the past. "Generally,air max italia, the new virus has been able to succeed him in the new species,talon louboutin, because all races of the immune system when confronted with a new vector invasion, have no ready-made antibodies can be against it." Cohen will star said. Influenza viruses can exchange genetic material with each other, merge into a new virus never seen before, this process is called antigenic shift recombination. This is because the genes of the virus is transferred from one body to another virus body virus, new virus evolution complete with an ability to infect the past is no ability to infect species. When an influenza virus enters the body.</p>
<p> antibodies adhered H protruding nail,nike oficial, put the keys to the block, it can not be locked,nike sito ufficiale, and living cells combined. Another group of antibody is adhered on the N-cap mushroom, to prevent the newly generated virus before being forcibly recruited from first erupted out of the host cell. Each antibody upon us will protect us, not to be a secondary infection of a particular strain of influenza virus, but it can not be combined with the new virus strains. In this case, a person's body must form new antibodies. The object of the attack of influenza,air jordan shop, usually non-small That old, because once the older people, the immune system will gradually decline,peuterey donna, more and more difficult to fight against the new virus.</p>
<p> then it implies that there has been spread from person to person; and there are more differences between the viral gene sequences if a patient who has, it implies that every patient has It is alone at the infection from birds. "Shanghai gene sequence of two patients revealed that both patients infected with the H7N9 virus region are very different, that they are from two different birds at infection. A virus in its birthplace of General diverse relatively high,chaussures giuseppe zanotti pas cher, first,louboutin pas cher femme, because the more virus in the longer event birthplace of cases accumulated, and second, because when the spread of the virus is only a small part of the birthplace of spread out, the birthplace of maintaining a higher diversity. This method proved the origin of human beings,air jordan shop, because human diversity is the highest in Africa. If we can find differences in gene sequence between cases somewhere big, is a good proof that here is the birthplace. " he said. In his opinion,piumini woolrich, no one influenza over a year or two completely extinct,air jordan, once the outbreak will last for many years,nike sito ufficiale, even if only in a small area popular, "H7N9 is not the same as the SARS virus after it's gone.</p>
<p> which is a whole two trends flu. And at the same time in the evolution of the virus is ,giuseppe zanotti sneakers, the body will produce its immune response and antibody. "hospital deputy director of the Beijing Respiratory Critical Care Medicine, said Cohen will star. "Proliferation of H7N9 is inevitable, but large-scale infection is hard to say, the lower the probability of the current situation from birds to infect humans, but not spread from person to person,air max italia, so we do not worry." For influenza pandemic risk assessment, the key question is whether there is evidence that the existence of inter-limited or more importantly, sustained interpersonal communication, which was emerging influenza pandemic mark. Andrew Lan Fort believes that because the flu virus mutates quickly, so compare every human patients infected with viral sequences can reveal whether there is a case of human infection with the H7N9 human. If a patient has a lot of very similar gene sequence of the virus.</p>
