Swine herds in China bird flu case has been mixed with swine flu is even more worrying

As of yesterday, swine influenza virus in Mexico has resulted in 159 deaths, the world's 10 countries confirmed cases, suspected cases of emerging countries and regions, more than 23. 然而，最坏的时刻也许尚未来临。 However, perhaps the worst of times have not yet the advent of. 香港大学医学院微生物学系教授管轶称，一旦导致猪流感H1N1病毒与业已在亚洲不少国家存在的高致病性禽流感病毒H5N1重配，可能导致灾难性后果。 University of Hong Kong Department of Microbiology, Professor Guan Yi said that once led to H1N1 swine influenza virus and has been there quite a number of countries in Asia, the highly pathogenic H5N1 avian influenza virus re-allocation may lead to disastrous consequences.

据悉，猪气管中存在着可与禽流感、人流感这两种病毒连接的受体，这种受体让猪可以携带禽流感、人流感和猪流感3种病毒，就像混合容器一样成为病毒基因重配的“温床”。 It is reported that pig trachea with the presence of bird flu, human influenza virus to connect these two receptors, this receptor so that pigs can carry the avian flu, human flu, and three kinds of swine flu virus, the same as mixed containers as a virus gene re-allocation of the "hotbed."

病毒由水禽传入猪群 Virus from birds imported swine

虽然H5N1一直被认为是禽流感病毒，但不同研究机构发表的论文都显示，H5N1病毒在中国猪群中早已出现。 Although H5N1 has always been regarded as the avian flu virus, but different research papers have shown, H5N1 viruses in swine in China is already there. 作为养殖大省的山东，近年来各地猪场曾不断发生以呼吸道症状为主要表现的疾病。 As a culture in Shandong province, in recent years, continue to occur around the farm to have respiratory symptoms of the disease as the main performance. 山东农业大学许传田对10个发病猪场的30份血清进行检测发现，该地区猪群H5和H9的抗体检出率为30%。 Shandong Agricultural University, Tian Chuan Hsu incidence of 10 of the 30 farms tested serum was found in the region H5 and H9 swine antibody detection rate was 30%.

2004年1月，中国农业科学研究院哈尔滨兽医研究所研究员李海燕及其同事在《中国预防兽医学报》上发表论文指出，为了解H5N1病毒是否已由水禽传入猪群，该研究团队2003年对广东、福建两省进行H5N1病毒抗体检测，发现这两省已出现H5亚型流感阳性猪群。 In January 2004, the Chinese Academy of Agricultural Sciences researcher Li Haiyan, Harbin Veterinary Research Institute and his colleagues in the "Chinese Journal of Preventive Veterinary Medicine" published a paper that in order to know whether the H5N1 virus from birds imported swine, the research team in 2003 of Guangdong and Fujian provinces antibodies to H5N1 virus detected in these two provinces has been positive for H5 subtype of swine influenza. 他们还从其中一头猪的鼻腔分泌物中分离到一株H5N1亚型流感病毒。 They also a pig from one of the nasal secretions of an isolated influenza virus subtype H5N1.

他们认为，H5N1病毒已传入中国猪群并引起猪流感的发生。 They think that, H5N1 swine virus has been introduced into China and caused the occurrence of swine flu. 而如果H5N1亚型毒株在猪体内获得在哺乳动物间水平传播能力后传入人群，将不仅仅是1997年香港禽流感事件的6人死亡，而将带来另一次瘟疫性人类流感的大暴发。 If the H5N1 subtype virus in pigs was in the capacity of horizontal transmission among mammals introduced to the crowd after, in 1997 to more than just the bird flu incident in Hong Kong 6 people were killed, and will bring another human influenza pandemic and a major outbreak.

应警惕最坏的可能 Should be alert to the possibility of the worst

目前，人们还无法详细了解本轮猪流感A型H1N1是如何发生的。 At present, people can not learn more about the current round of swine influenza A H1N1 How did it happen. 但美国弗吉尼亚理工学院暨州立大学生物医学科学与病理学系教授XJMeng博士认为，H1N1病毒不但能从猪传染给人，也能从人传染给猪。 However, the U.S. Virginia Polytechnic Institute and State University, Biomedical Sciences and professor of pathology XJMeng Dr., H1N1 virus has spread from pigs to humans, who can also spread to pigs. 也就是说，一旦中国、印度尼西亚以及越南这些H5N1的疫区，遭到这一轮重配之后的猪流感侵袭的话，重配就很有可能发生。 In other words, as soon as China, Indonesia and Vietnam the epidemic of these H5N1, has been allocated for this round of re-invasion after the swine flu, the re-allocation is likely to occur on.

广东省疾病预防控制中心黄平研究员认为，流感病毒重配后会存在多种可能，如病毒传播能力及致病性都变弱，但也无法排除最坏的可能，即重配后的新病毒可能同时具备猪流感H1N1的社区传播能力及H5N1的高死亡率。 Guangdong Provincial Center for Disease Control and Prevention researcher Huang believes that the virus will re-allocation of the existence of a wide range of possible transmission of the virus, such as the ability and pathogenicity are weakened, but it can not be ruled out the possibility of the worst, that is, after the re-allocation of the new virus may also have community-based swine influenza H1N1 and H5N1 spread of the ability of the high mortality rate.

据世卫统计，截至2009年4月23日，全球共有421例人感染H5N1病毒病例，死亡257例。 According to WHO statistics, by April 23, 2009, the global total of 421 cases of human infection with H5N1 virus cases, 257 cases of death. 人感染H5N1病毒死亡率达61%，远高于SARS9.6%的死亡率。 Of human infection with H5N1 virus, mortality reached 61%, much higher than the mortality rate SARS9.6%. 《财经》供稿 "Financial" feeds
