swine [swain]做名词 的意思是猪　 讨厌鬼, 下流坯, 猪猡

Flu是流感的意思swine influenza就是猪流感。也可以简称为swine flu。猪流感病毒swine influenza vinus也可以简称SIV，我们以前都听说过H5N1型高致病性禽流感，这次的猪流感病毒类型为H1N1型。H被称为红细胞凝聚素，N被称作神经氨酸苷酶，它们都是糖蛋白，分布在病毒表面。H有1-15个亚型，N有1-9个亚型（在甲型病毒的情况下）。由于H和N的组合不同，病毒的毒性和传播速度也不相同。

　　我们顺便说说和"猪"有关的词，swine，pigs和hogs，这三个词都可以指猪这种动物。swine是"猪"比较通用的说法，而pig可以侧重指小猪，hog就可以偏指那些份量已经可以上市或者接近上市的猪。被阉割的公猪叫barrow，小母猪叫做gilt，不要以为知道一个pig就可以横扫英语世界哦。

新闻报道 ： WHO declares swine flu outbreak "public health emergency

　　 The World Health Organization (WHO)on Saturday declared the swine flu outbreak in Mexico and the United States a "public health emergency of international concern" and urged countries to be alert.

　　　　 Based on the advice of a WHO emergency committee, Director-general Margaret Chan "has determined that the current events constitute a public health emergency of international concern," the UN agency said in a statement.

　　　　 The WHO chief is recommending, on the advice of the committee, that all countries intensify surveillance for unusual outbreaks ofinfluenza-like illness and severe pneumonia, the statement added.

　　　　 However, more information is needed before a decision could be made concerning the appropriateness of the current "phase 3" alert level of a pandemic risk, according to the advice of the committee, which is composed of international experts in a variety of disciplines.

　　　　 The WHO's pandemic alert includes altogether six phases. "Phase3" means "no or very limited human-to-human transmission."

　　　　 The emergency committee was established in compliance with the International Health Regulations (2005). It convened its first meeting on Saturday to assess the swine flu situation and advise the WHO chief on appropriate responses.

　　　　 After reviewing available data on the current situation, committee members identified a number of gaps in knowledge about the clinical features, epidemiology, and virology of reported cases and the appropriate responses, the WHO statement said.

　　　　 The committee also noted that answers to several specific questions were needed to facilitate its work.
