2004年元旦刚过,一种被命名为H5N1的高致病性禽流感病毒迅速席卷了整个亚洲,给刚刚从非典噩梦打击中苏醒的人们当头一棒。目前,禽流感尽管得到了各国政府的广泛重视和强力控制,世界卫生组织等国际机构也纷纷把注意力集中在禽流感上,但禽流感依然在亚洲,乃至世界蔓延。禽流感到底会造成多大的危害,依然还是一个大大的未知数。禽流感是禽流行性感冒的简称,它是一种由甲型流感病毒的一种亚型(也称禽流感病毒)引起的传染性疾病,被国际兽疫局定为甲类传染病,又称真性鸡瘟或欧洲鸡瘟,而本次在亚洲流行的病毒被命名为H5N1高致病性禽流感病毒,尤以其对禽类的感染性大、死亡率高(达100%)而让人谈病色变。到底禽流感是怎样引起的?它怎样传播、怎样致病?它能否给人类造成巨大的危害?禽流感到底有多可怕?打败禽流感最关键的问题是什么?我们应该怎样防治禽流感?带着这一系列的问题,我们广泛听取了从事禽流感研究、预防一线的专家意见,他们几乎异口同声地表示:禽流感并不可怕,预防是关键!
Just after New Year’s Day in 2004, a highly pathogenic avian influenza virus named H5N1 swiftly swept across Asia, giving a big blow to the people just waking up from the SARS nightmare. At present, despite the widespread attention and strong control of bird flu in many countries, international organizations such as the World Health Organization have also focused their attention on the bird flu. However, the bird flu is still spreading in Asia and even the world. The extent of the bird flu will cause much harm, still is a big unknown. Bird flu is short for avian influenza. It is a contagious disease caused by a subtype of influenza A virus (also known as bird flu virus). It is also classified as Class A infectious disease by the OIE, also known as Genoevirus or European poultry plague, and the virus that is endemic in Asia is named as H5N1 HPAI, especially in birds with high infectivity and high mortality rate (up to 100%), change. How does the bird flu cause? How does it spread? How can it cause disease? Can it cause great harm to human beings? How horrifying the bird flu is? What are the key issues to fight against the bird flu? How should we prevent the bird flu? With this series of questions, we have listened extensively to the opinions of experts who are engaged in the research and prevention of bird flu. They almost unanimously said: Bird flu is not terrible and prevention is the key!
