First sheds and in taking place one at present The expert thinks first flows in this summer and does not know " Prevail "
Www.zjonline.com.cn was reported recently on April 29, many citizens have found, first flows and fades out in the sight slowly. Reporter yesterday (the 28th) Department of public health knows from the province, receive the notice of Ministry of Public Health, since April 21, the epidemic situation has flowed to prevent and control and already enter and summarize and assess stage in our country first. Originally the epidemic situation of a newspaper every week changes into a newspaper per month too. According to the monitoring data of influenza, the expert of Ministry of Public Health thinks, the first type H1N1 influenza of our country is low at present to take place for period, the virus is monitored and has not found that obviously make a variation. This main crowd has inoculated first and flowed vaccine has played crowds and resisted diseases on the function of protective screen? Will first flow to still stage a comeback? Yesterday, the famous virology expert of our country of staff reporter's special visit, academician of the Chinese Academy of Sciences, medicine courtyard honorary president Mao JiangSen in Zhejiang Province. The group that he led succeeded in developing hepatitis A vaccine of autonomous innovation, was appraised as one of ten major news the Chinese scientific and technological circle in 1995. Will not suddenly present the new virus family's reporter: In recent years, flow from SARS to bird flu, the first, more and more like new virus, what is the matter? Mao JiangSen: In most recent 30 years, viral disease seems to increase, bring some misunderstandings to everybody too, think the new virus has come, but new viral disease does not equal the new virus, the virus may exist in the world in this one for a long time, the appearance of the virus is earlier than the mankind, the relation between virus and people has been in evolution all the time. The appearance of the new virosis is that the prevailing virus was infected to on people among human because not originally mostly. There are 23 big families of the virus altogether, will not suddenly appear in a new virus family. SARS and first flowed the virus upload from animal's body on people. Most virus is the very stable asking: The virus transfers to life from the animal, because did the virus make a variation? A: Where to infect dying of illness known alone to report the virus makes a variation, virulence has been strengthened. In fact generally speaking the virus and genetic stability are a mainstream, it is a result that must be evolved every year, the variable gene is easy to be eliminated in evolution instead. Why sometimes the virulence displayed on this person is strong then, the reason is not that the virus makes a variation, but this person's immunological function is worse than others, or there are certain immune defects. Get up to very important factor in people's immunological function is pathogenic in virus, the virus is pathogenic to mainly show: First, see in which position the target cells of the virus are, if in the important internal organs, it is dangerous and high; Second, relate to the fact that the reproductive capacity duplicate ability. First flows can't ask to prevent and control only by isolating: The first type H1N1 influenza that popular to last year, the tactics of prevention and control of every country were different, also there are many sounds that review, how do you see? A: I want to talk about the tactics of prevention and control of our country. When first type the intersection of H1N1 and influenza appear just, measure that our country expect at first whom virus refused except country. This kind of idea can certainly be understood, but from the viewpoint of virology, it is not feasible. Because of such a upper respiratory tract virus, symptoms shown are fewer and slighter, it is very difficult to be discerned and isolated that these people are. This whether virus, in evolve the intersection of infection and characteristic that obtain in the course for a long time, virus have such skill all, the gene has been eliminated, can not survive for more than several ten million years for a long time. So, though H1N1 is like SARS, the virus comes from the animal first, but their two have very big difference, what SARS virus is attacked is the immune cells of lung cell, the dominance is a main fact, the case fatality rate is relatively high, it is obvious to isolate the result. H1N1 virus has a large amount of recessiveness to infect, will not be managed and healed and it is difficult to achieve the goal of preventing to isolate after infecting. One prevails in infectious disease can predict that ask: Each infectious disease has high one of one, is that all right to predict? A: There is a prevailing course in influenza, a size prevails and can roughly be calculated, but need a lot of parameters, for example virus can bring in body how long it will be poison, virus list amount of quantity, cell can duplicate virus what quantity have, factors such as more easily infected group's quantity,etc.. Can be in order to probably estimate, can know in this way how long it can probably prevail from these data, if have unexpected, H1N1 may know, withdraw from, prevail situation in this summer, go, change, depend on profit and equilibrium of fraud artificially. In fact, dealing with H1N1 virus our focal point should be put to on the treatment of the serious disease case, especially should pay attention to protecting person and disadvantaged groups with low immunological function well, offer kind treatment, pay more concern. Scientist Mao JiangSen belongs to brief introduction of famous virology family, academician of Chinese Academy of Sciences, American virus academician, chemical academician of U.S.A.. Institute's honorary president of medicine of Zhejiang, doctoral supervisor. He has made important contribution in the countermeasure of prevention and control which is infected with to the virus disease, for instance research to diseases such as poliomyelitis, A -type hepatitis, SARS, measles, influenza, encephalitis B,etc.. There are important achievements in basic theoretical research of virology, go against the hereditary gene and duplicate, the research in respects such as the single member's impact on virus structure and function,etc. obtains 6 patents, 1 international monopoly.
