This time the mortality in popular first type H1N1 influenza of the whole world is 0.4%, this is jointly conclusion which the research group draws through calculating that World Health Organization and Britain, Mexican scientist make up. This is smaller than large 2% mortality while prevailing of Spain's influenza of 1918, is much higher than ordinary seasonal influenza by 0.1% mortality. In addition, the research group also extrapolates until the end of April, the number of people that Mexico is infected with influenza virus of new H1N1 is about 23,000, well-above the number (2059 up to May 11) of patient that Mexico has already made a definite diagnosis of at present . The research group assumes the cases of the countries all over the world spread through the tourist from Mexico at first. Then study number of the infected of countries all over the world, count from from Mexico to all parts flight and passenger in the intersection of time,etc. and various data that Mexico stay, and analyzed the change of the virus gene, thus infer and appear to the mortality of this influenza and local number of the infected in Mexico before the end of April. Result of study reveal the intersection of influenza and first the infeted this will infect 1.4 to 1.6 people still, and person-to-person mutual infection is up to for 14 to 73 times by the end of April. From look on being infective, though unable compared with great influenza in 1918, much higher compared with ordinary seasonal influenza. In addition, the research group has also released the morbidity source of this influenza: First case appear on February 15, drawing the intersection of storehouse and the intersection of Lip river and the intersection of profit and inferior village about 200 kilometers east of place lie in the intersection of Mexico and city. (the intersection of reporter and Ge stock, exceed while being old)
