Jq Ez6_{0An outbreak of highly pathogenic avian influenza caused by H5N1 virus occurred in Vietnam, Japan and Korea, commencing in December, 2003. By February, 2004, it has been distributed widely in Asia and brought heavy losses. H5N1 are ball-like RNA viruses, birds can shed them via respiratory system, ocular secretions and feces, sometimes transferred to human and cause lethal infection. H5N1 patients have prominent features of reactive hemophagocytic syndrome,bronchiolar inflammation, necrosis of bronchial epithelium and organizing,diffuse alveolar damage with interstitial fibrosis.

2003年12月，H5N1型禽流感病毒在越南、日本和韩国爆发，到2004年2月，该病毒已在亚洲广泛蔓延并带来了巨大损失。H5N1是球型RNA病毒，禽类间可通过呼吸系统、眼分泌物和粪便传播，也可传染人类甚至导致死亡。H5N1感染者的特征是反应性噬血细胞综合征、细支气管炎症、支气管上皮坏死和机化、弥漫性肺泡病变和间质纤维化。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
