but many experts believe that it is so effective in preventing the flu before the outbreak worldwide. Currently, Shanghai shut down all poultry market practice, in theory,tn, also be beneficial.Another particularly close watch on the pig. The study found that both avian influenza virus or human influenza viruses can infect pigs,tn, and they can "nurture" very well - this is a good place in the middle of recombinant variation. Therefore,tn, from this point on, do not recommend large-scale pig and poultry rearing plant too close to the plant planning. In fact, at the beginning of 2009 H1N1 virus appeared on a mix of swine flu and avian flu genes from a human influenza virus.Then.
will be getting shorter, spreading the force will be weakened.As ordinary citizens, we should know that the spread of infectious diseases must meet three factors: the source of infection, transmission and susceptible populations,tn, are indispensable.So we usually do not have too much to worry about. Just reduce contact and maintain good health habits,tn, much smaller chance of contracting the disease.In the fight against the virus in the development of major current human therapeutic drugs, is trying to block certain aspects of viruses,tn, and thus inhibit viral reproduction. Currently.
spread through the air; but the situation is somewhat non-airborne,tn, it is difficult to explain.Preventive measures currently published, wear a mask or reduce contact with birds, to a certain extent, can help to prevent avian flu. However, some people go to extreme destroyed nest on what,tn, after all, carry the bird flu virus is in the minority. And if the birds should be ruthless,tn, then pigs, dogs, cats these same potential carriers it possible Moreover, poor thermal stability of the influenza virus. As temperatures rise in the future, the sun's ultraviolet enhanced time they can survive in the environment.
these may be in the body of an infected host, there are other influenza viruses (such as human influenza A virus infected people just another bird flu), then If recombination variation, you can make the avian influenza virus from human influenza viruses out there, get the ability to spread among the population, the consequences could be disastrous.So, culling poultry infected with avian influenza,tn, can reduce the probability of human infection with avian influenza. In 1997 the Hong Kong Government in three days culled millions of poultry in Hong Kong,tn, although some extreme.
two neuraminidase (referred to above is "N") inhibitors,tn, Tamiflu and zanamivir, is considered to be the cure for the treatment of influenza A virus infection. But humans far away once and for fashion,tn, the 2009 pandemic H1N1,tn, had been on these drugs produce drug resistance. Fortunately, H7N9 drug Tamiflu resistance does not seem in it with the help of Shanghai, a 4-year-old boy was cured, of course, this must be in the timely treatment of the condition.In fact, the reason for such a high mortality rate caused by the current H7N9,tn, it is because:One of its early symptoms of lack of specificity.
the virus mutation and evolution, what is the mechanismStill unknown.Known: influenza viruses poor thermal stability, as temperatures rise in the future, the time they will be getting shorter survivalUnknown: Currently on the mode of transmission of influenza,tn, not a thorough understanding of the situation and some non-airborne also difficult to explainCurrently,tn, in the fight against influenza virus in humans is still only on the defensive, but the situation is not very optimistic.Even, the current mode of transmission of influenza, understand and not very thorough. The typical mode of transmission of influenza is spread by coughing and sneezing release of the virus.
