"This occurrence's suffering from a swine influenza epidemic situation at the person of Mexico is a typical virus to across a kind of boundary to deliver.From the gene set the result that measured a preface to see, have this year of as to it's didn't the flu vaccine prevent°from a function."On April 26, medium researcher from microorganism graduate school in section hospital, "973" the topics"the animal source sexually transmitted disease poison acrosses the member mechanism of a kind of boundary dissemination" chief the high blessing of scientist to 《 science Times 》mean.According to The Xinhua news agency news, World Health Organization confirms on April 24, more than about a months, Mexico discovers totally more than 880 swine influenza like the sufferer, 62 among those people die.This kind of virus is a kind of new virus of occurrence gene mutation, most make what people worried BE, it has already spread between each human relations.The general manager Chen Ping rich Jean of World Health Organization meant recently that this kind of Swine influenza virus of having spread between each human relations existed to turn into very clearly spread sexually transmitted disease poison of possibility, and the development"inscrutability" of situation.Chen Ping rich Jean says that this kind of the new virus of dissemination makes the mankind face "rigorous situation" between each human relations."The swine influenza epidemic situation this time is very serious, because is learning blood kin the characteristics of last likeness,wholesale MLB snapback also explains according to the pig and the mankind both of the immunity source and antigen are alike.This means that influenza virus if soon adapt to in the pig body, will also soon adapt to so in the human body.It is more more serious than bird flu of the H5 N1 type."Medium microorganism in the section hospital says researcher, Liu Wen Jun, .American disease controls confirmation in the center, Mexican Swine influenza virus is an A/H1 N1 type, this poison stub is a kind of new variation virus, mankind's influenza virus, North America the virus of bird flu, and North America, Europe and the hybrid body of Swine influenza virus in Asia.Blazing with spinal cord ash quality to wait single virus of gene is different, influenza virus constitutes to°from 8 gene parts a gene set, "mainly of two gene parts are pig sources of, other parts are constituted together by the pig source, person's source and birds source, Mexican Swine influenza virus this time is that one is miscellaneous to hand over a body", high blessing explanation.Is miscellaneous to hand over virus is more easily let people comprehend of a kind of call method, the professional technical term is called gene part to weigh a row, were also 8 gene parts to carry on to re- arrange a combination and form a new virus form."This is to cause the epidemic situation let main reason of dismay in the whole world, the another lets an ill at ease factor of people BE, dying the big part in the crowd is an adult."Gao Fu Shuo.At Gao Fu Kan, after several year agos occurrence person suffered from bird flu, the Epidemiology expert has been worrying in 1918 the craze of Spanish flu again repeats, and that of influenza virus is also a same H1 N1 type, discovered, also similarly regarded green prime of life infection as principle in the barracks at the earliest stage."Influenza virus contains two surface structure egg white.The H representative is a blood Ning vegetable egg white, the N represents nerve ammonia sour Mao(have something to do with virus' invading), these two egg whites are also two surface antigens, according to the antigen dissimilarity, also was divided into influenza virus a different model number."Liu Wen Jun says.In addition to 8 gene parts can with source different outside, the gene set fragment of influenza virus can also take place to mutate.This is also influenza virus why difficult defend, vaccine why use no matter reason."The H representative's blood Ning vegetable egg white the whole world have 16 kinds of, N representative of nerve ammonia the sour Mao has 9 kinds, after arranging will produce up to 100 different combinations."Gao Fu Shuo.According to the introduction, person influenza virus of the familiar infection is H1 N1 type and H3 N2 type, not and familiarly have H2 N2 etc..But with others homology, all of pig, horses are to easily be infected these two kinds of viruses.Gao Fu Shuo, swine influenza's occasionally being infected person is passing by to once take place as well, but just send forth, don't form popular trend.This Mexico big area swine influenza happens and also explains that this is a kind of evolution that is miscellaneous to hand over virus to adapt to a human body more.Although is a kind of new virus, its spreading path and former influenza virus is similar and mainly pass air and contact dissemination.French expert then points out that Swine influenza virus afraid heat, eating to burn the familiar pork can't be infected swine influenza."Our a new research result also proves, Swine influenza virus comes from person's influenza virus.The comparison that evolves according to the genetics member, the evolution of person's influenza virus has to be quick than Swine influenza virus.Speak on the other hand, person's getting flu wills also infect to the pig, but still has no evidence."Liu Wen Jun has been being engaged in the member evolution of the etc. virus of animal flu, pathogenic and be infected of across a kind of to spread mechanism and the research of the virussafe medicine and the research of the development.In 2005, Liu Wen Jun made the relativity research of person's flu and Swine influenza virus member evolution comparison in Guangdong region.Discover in this research, the first source is still person's influenza virus of the H3 N2 type virus of swine influenza in same region is a person influenza virus evolution a branch within process."The Swine influenza virus occurrence heavy row will be more multifarious, 5 poisonous stubs that once made analyzed to discover, had 3 to take place among them gene to weigh a row."Liu Wen Jun says.Aim at whether this time Mexican swine influenza will stream into the problem of our country, Liu Wen Jun thinks, because of living creature evolution creation of the long-term orientation relationship with of holdout is different, so differently growing to belong to an easy emotion of is different, and Asian whether will the easy feeling is this time new virus, also return a beard research.In addition, currently also still not the ability keep on time to make to calculate to this time epidemic situation of flu.Currently, our country the equal value virus study.High blessing introduction,cheap oakley sunglasses establish in the 2008 nation of 16 great science and technology particularly in the item, also established an infectious disease graveness particularly item;At the same time, source microorganism in the Chinese science, hospital and immunology point laboratory also established last year, the purpose is a research mankind, animal and interaction between the viruses, and across a kind of boundary to deliver, immunity mechanism etc..
