Staff reporter Zheng dexterous On June 11, World Health Organization claims to warn the rank of first type H1N1 influenza and rise to superfine 6 grades, claim global influenza is great to prevail and already come. Will it be at dusk 12, WHO stationed in China represent ZhuoSheng Han emphasize, large to warn rank, promote as most high while being prevailing in Beijing, having reflected the geographical range that the virus propagates, but not the severity of disease. As to this, how to understand correctly on earth? China CDC ( Center for Disease Prevention and Control) Deputy Director, China CDC first type H1N1 influenza prevention and control director of office of leading group researcher Yang WeiZhong pointed out when being interviewed by staff reporter a few days ago, WHO promotes first type H1N1 influenza and warns the rank to there are double intension at most, the epidemic situation alarm of awakening the deaf that it rings, blow science and prevent and control the clarion call of the new influenza too. The epidemic situation will be said in more swift and more violent Yang Wei while spreading, this first type H1N1 influenza epidemic situation of spreading in the whole world, an outstanding characteristic is that the virus propagates the force strongly. Since in April of this year WHO reported formally that made a definite diagnosis of the case in first type H1N1 influenza, among short 2 months, this virus spreads in the whole world rapidly at the surprising speed promptly, the range of spreading goes to more than 70 countries five continents. At present, except Mexico and U.S.A., Australia, Britain, Spain, Japan, Chile confirm it appear first type the intersection of H1N1 and the intersection of influenza and colony nature to a certain degree travel within the border. The situation prevails so, has already reached the top cordon that WHO has delimited previously. Yang WeiZhong claims, first type H1N1 influenza propagates the strong suggestion for the extremely quick speed, in front of this new influenza virus, the mankind has no immunity, the infection incident is ill. In a situation that it is such close to sow scattered, the whole world so extensively to integrate in the epidemic situation, the first type H1N1 influenza epidemic situation will further spread with higher speed irresistibly. The low case fatality rate of the serious disease rate is too low to change to tell reporters in Yang Wei, appraise the severity of a certain infectious disease, need to see two respects. One is to propagate the force, a severity that is pathogenic. Though the spread strength of the first type H1N1 influenza is very strong, its serious disease rate, case fatality rate are not high. Yang WeiZhong says as to this global first type H1N1 influenza epidemic situation how to develop in the future, it is still unable to predict at present. But observation so far, display while being overall at the clinical disease this serious disease rate low still and case fatality rate low. Lian Yue will come, is having virus to separate in samples that the first type H1N1 influenza patient gather of various countries out constantly. All examining reports reveal, initiate regional crowd's ill causing the etiology, what prevailed caused the pathogenic homology to be up to more than 99% with U.S.A., Canada and Mexico; On the virulence of the virus, have not found the critical intensity increases; In drug resistance, first type the intersection of H1N1 and influenza virus pitch the intersection of rice and Wei that to neural the intersection of amino acid and the intersection of enzyme and inhibitor medicine (the intersection of Damien and Philippines) The response is still sensitive. Vaccine no knows and fails to producing the invalid worry because of virus transmutation of first type H1N1 influenza vaccine that is hit because of virus transmutation, WeiZhong Yang say influenza virus will morph constantly, but virus namely sudden change to vaccine to it invalid possibility big totally during that vaccine produce several month. Can believe, future several months later, effective vaccine can produce the protective action on key crowd and high-risk group. At present, China CDC adds this vaccine and researches and develops the group on one hand; On the other hand, are launching the immune tactics of first type H1N1 influenza to study actively too, guarantee to inoculate safe and effectively after these vaccine prepare, succeed in. The strategy of prevention and control changes to and monitors first type H1N1 influenza and warns the rank and rises to superfinely conventionally, undoubtedly indicate the mankind should enter the new stage to this great epidemic disease. Prevention and control strategy, too from meet an urgent need, fight, turn protracted war to, change regular to monitor, prevent and control for a appropriate sustainable one, monitor variation, condition and death of virus especially, control to break out epidemic situation community. WeiZhong Yang brief on, WHO promote first type the intersection of H1N1 and influenza, warn rank to while being most high, prevail global influenza situation divide 3 kinds into. First, have already taken place in the countries and regions which the extensive community of first type H1N1 influenza has propagated, such as Mexico, U.S.A., Canada, Britain, Japan, Australia,etc.. Second find, input case into but find country that extensive community propagate yet already, such as China and most Asian countries. Third, does not find that report the country of the case yet at present, such as most African countries. WHO requires different countries of epidemic situation state, according to the concrete reality in this country, adopt and is suitable for and with more sustainability the action more. Yang WeiZhong passes on the public through this newspaper, national influenza monitors the network and monitors the epidemic situation tendency tightly, country all related departments in close joint defence unite accuse of hand in hand. As the public individual, needn't be panic at all, it is easy to get used to but need to be correlated with the country to point out and form the hygiene, reduce the possibility of infecting the epidemic situation, avoid passing disease to others while protecting one's own too.
