Washington, May 23 (Xinhua) ' Reporter Ren HaiJun) According to report of May 23 of U.S.A. " the New York Times ", a result of study announced a few days ago reveals, the pig is the important host of influenza virus, but people's concerns about pig's body inner influenza virus for a long time are not enough. The relevant expert says, in view of first type H1N1 influenza virus and origin of pig's influenza virus, the international community should strengthen and monitor influenza virus in pig's body. It is reported, there are few countries that controls the epidemic situation of pig's influenza in the world at present. United States Department of Agriculture reveals in the beginning of this month, U.S.A. spots check 500 only in 100 million pigs every year, in order to judge the spread situation in American pig's body of relevant virus. It is reported, an international scientific research group delivers a report saying on American Science on May 22, the gene order-checking result that they carry on to 51 first type H1N1 influenza virus samples from U.S.A. and Mexico reveals, the 8 of virus great to make up in the gene including 2 mix with the intersection of bird flu virus and the intersection of pig and the intersection of influenza virus and gene of gene in whom Eurasia find 1979, 3 kinds of pig influenza virus genes found in North America pig's body, new virus gene,etc. formed after 2 kinds have been hybridized by pig influenza virus in North America. So the expert thinks, first type H1N1 influenza virus will probably already be travelled for more than 10 years but not finds on the pigs of some countries. But researchers are not still clear when, where first type H1N1 influenza virus specifically begins to pass from the pig to somebody at present, not clear either how it possesses the ability to spread among persons rapidly. However, genetic analysis shows, first type H1N1 influenza virus is not stronger than other first type influenza virus toxicity. The researchers who deliver this report say, will need strengthening and monitoring influenza virus in pig's body in the future, this kind of virus is a potential source of human influenza virus. U.S.A.'s disease controls and prevents influenza research director Nancy and Cox of the centre but pointed out while commenting on the above-mentioned report, this research proves, global and necessary to monitor influenza virus in pig's body more systematically.
