禽流感病毒-新世纪人类的头号敌人日前世界卫生组织(WHO)全球流行性感冒计划负责人史托尔提出警告,他认为继SARS之后,下一轮人类面对的新传染病很可能是禽流感,禽流感病毒(H5N1)近年遍及亚洲多国地区,许多传染病专家提出警讯禽流感病毒可能有机会变异成为「人传人」的流感病毒,估计H5N1型病毒产生变异时,可能会感染全球多达30%的人口,并导致200万至700万人丧生,超过十亿人罹病,因此国际粮农组织、畜牧组织与世界卫生组织在二月下旬共同在越南胡志明市召开第二次国际防疫会议,邀集近30个国家地区约150位专家商讨对策,达成支应亚洲地区防范共识,期能避免发生更大的疫情。流感病毒造成全球近亿人死亡流感病毒可分为A、B、C三型,抗原为H(15种)与N(9种),H与N再组合成为复杂不同的病毒型态侵犯细胞。A型较容易发生变异,抗原转变多,容易引发大规模流行,病毒可存在人、动物之间,通常大的突变就是发生在人与禽类交互感染时,而猪就是人与禽间交互感染重要的媒介。人类几次流感大流行,约计造成全球近亿人死亡,分别为1918、1957、1968、1977年皆已被定为A型流感。
Bird flu virus - the number one enemy of humankind in the new century A few days ago, World Health Organization (WHO) head of the global influenza program Stoll warned he believes that following the SARS, the next new round of human infectious diseases is likely to be birds Influenza virus (H5N1) has spread to many Asian countries in recent years. Many epidemiologists have warned that the bird flu virus may have the opportunity to mutate into “human-transmitted” influenza virus. It is estimated that when the H5N1 virus is mutated, the virus may be infected more globally Reaching 30% of the population and killing 2 to 7 million people and leaving more than 1 billion people affected. Therefore, the second international conference on epidemic prevention was held in Ho Chi Minh City, Vietnam in late February by the International Organization for Agriculture, Animal Husbandry and Fishery (FAO) and the World Health Organization (WHO) Some 150 experts from nearly 30 countries and regions were invited to discuss countermeasures so as to prevent the common understanding in Asia and prevent a bigger epidemic. Influenza virus causes nearly one billion deaths worldwide Influenza virus can be divided into A, B, C three types of antigens H (15 species) and N (9 species), H and N recombined into a complex different virus type violations of cells. A type is more prone to mutation, antigen transformation and more likely to lead to pandemic, the virus can exist between humans and animals, usually a large mutation occurs in humans and birds interact when infected, and pigs are important for the interaction between humans and birds Media. Hundreds of human flu pandemics have caused the death toll of nearly 100 million people in the world, 1918, 1957, 1968 and 1977, respectively.
