    <p> H2 and H3 type) or a human-type and recombinant avian influenza virus type (such as H5 and H7 type, etc.). In August 1997,hogan rebel, scientists in China, Hong Kong A 3-year-old child flu deaths in vivo isolated the H5N1 highly pathogenic avian influenza virus.</p>

    <p> we Chinese people became sentry people. "Guan said. (Reporter _ Xuzhuo Jun) Q: H7N9 virus would endanger the life? It will evolve into a pandemic it? # # # Dissemination capabilities mortality # A: H7N9 is unclear the real death rate, as are currently found in critically ill patients, can not determine the number of hidden cases or mild cases. Now,spaccio hogan, with the increase of patients,sneakers hogan, H7N9 mortality rates began to decline. In the case of human to human transmission can not be, H7N9 is difficult to cause a pandemic. H7N9 virus is a low pathogenic virus, and H5N1 is the highly pathogenic virus, but that does not mean harm H7N9 smaller than H5N1. Highly pathogenic or low pathogenic virus virus is based on the power of the virus to poultry categories. For humans, low pathogenic avian influenza virus H7N9 but more difficult. Once infected with the highly pathogenic virus in poultry.</p>

    <p> the virus must try to make it to retain a certain number of hosts for its infection, the virus is no way to survive,outlet hogan, after all, in the case of loss of the host. (Reporter _ Xuzhuo Jun) Q: WHO says, H7N9 bird flu virus mutation occurs,hogan interactive, it becomes easy to infect humans. What factors determine the avian influenza virus to infect humans? # Mutant # A: Bird flu virus could mutate so that the avian influenza virus hemagglutinin protein can bind to human type sialic acid receptors, so there may be infected with the avian influenza virus in human airway epithelial cells. Any kind of virus infection has a host-specific,outlet hogan italia, depending on many factors, one of which the most important is whether the combination of the virus-specific host cell membrane surface receptors. Influenza virus infection is generally considered to host specificity,hogan outlet, no cross-species transmission. Influenza viruses can infect humans typically human influenza virus (such as H1.</p>

    <p> will be a large area of death, humanity easier to find the source of the virus. And poultry H7N9 infection and have no symptoms occur,hogan outlet online, poultry can carry and spread the virus secretly, are not known, it is difficult to find a human or find the source of the whole virus, there is no way to eradicate the virus,hogan scarpe, the virus may be present in poultry in vivo long-term, continue to infect humans. H7N9 virus seems powerful, at the beginning of the time found people infected with the virus, the death rate was 60%,hogan online, with an increase in patient mortality began to decline. In fact,hogan donna, doctors do not know its true death rate,sito hogan, as are currently found in critically ill patients,hogan donna, is not some hidden cases or mild cases, is still unknown. In general, the higher the death rate of the virus, its destructive power will be higher. But specific to influenza, it seems just the opposite. "Defeat bird flu,hogan scontate," a book that the author Ai volts, when the virus begins to decrease mortality rates, such as down to 10% or less, the environment was ripe to might plague pandemic phase occurs. For example,outlet hogan italia, in 1918 it caused the 2500-4000 Spanish flu million deaths, the death rate is not high,scarpe tipo hogan, 2.5% -5%, but billions of people infected worldwide. When the virus spread from person to person more and more proficient at the time,hogan sito ufficiale, it will be wonderful to decrease mortality rate, the purpose is to allow the host species can continue to spread the virus,hogan store, if the virus while maintaining a high mortality rate, but also easily in human spread of infection they will be in danger of extinction of species. From an evolutionary perspective.</p>
