More fatal reason is announced after first flows the virus makes a variation
London, October 22 (Xinhua) ' The reporter is yellow) British kingdom Institute of Technology publishes the press Communique and says, its researcher found more fatal reason after a certain variation takes place in first type H1N1 influenza virus on the 22nd. The communique said, once a kind of code happened in albumen of surface of first type influenza virus was " D222G " Variation,will become this virus fatal. World Health Organization statistics show, have infected this kind of variation virus in the first type influenza case only less than 2%, but the death toll that it causes accounts for about 7% of total death toll of patient. Researchers find, the reason why this kind of variation virus is more fatal is that stronger that it invades the ability of the cell of the respiratory tract cilium. Usually the cilium in people's respiratory tract will be swung constantly, take various foreign matters which enters the respiratory tract to the larynx, then list it outside the body through coughing. But if cilium cells are infected by this kind of variation virus, the cilium will be lost and swung ability, then the self- clean mechanism of the respiratory tract is weakened, virus and bacterium can drive straight in, reach the lung and initiate pneumonia and cause higher mortality finally. Researchers say, if this kind of variation virus travels extensively, the consequence will be relatively serious. Though World Health Organization has already announced global influenza has been over greatly and prevailingly, but people still can't relax vigilance, because first type H1N1 influenza virus probably makes a variation constantly, once pathogenic and spread very strong new variation type appears, may still lead to the fact influenza prevails big.
