禽流感

       　禽流感是由A型感冒病毒引起的，主要波及鸟类和家禽，根据感染的病毒株、宿主和环境情况的不同禽流感可能出现轻度症状甚至无症状，或者高死亡率、迅速扩散。禽流感病毒主要出现在Waterfowl 的肠道和粪便中，其他易感鸟类通过呼吸道或接触传染。流感病毒对大多数清洁剂和消毒剂敏感，通过加热和烘干很容易使之失活，但是有机材料可以保护流感病毒不失活，有传染性的病毒在肥料中最多可以存活105天，所以去除有机材料是有效消毒步骤的一部分。在大多数情况下感染鸟类的流感病毒不会感染人类，反之亦然。但是在1997年，香港的一种禽流感病毒对人类和鸡均具有感染性。亚洲最近出现了禽流感的流行，越来越多的人们关心是否一种新的传染病会在全球肆虐？为此CMBI检索了2002年以来禽流感相关文献，集结成辑供参考。此外CMBI曾在特别报道124期有过关于流感的特别报道，其他相关资料请参见WHO官方网站，并可用相关关键词（如：Influenza）通过CMBI文献查询获得。
