世卫组织研究印尼禽流感病例 (WHO Studies Bird Flu Case in Indonesia)

世界卫生组织专家正在对印度尼西亚一个家庭中7名成员死亡禽流感病例进行研究，这是迄今为止禽流感病毒传播中最严重的发展。世卫高级官员说，他们对印尼这个月禽流感传播感染范围程度以及感染源头极为担心。一个家庭中7名成员在过去的3个星期内相继死亡，第8名成员也感染了H5N1禽流感病毒，这起发生在苏门答腊北部死亡事件是已知同时感染禽流感人数最多的病例。

在印尼对病毒样本进行化验的世卫专家说，他们还没有找到证据显示亚洲地区的禽流感病毒已经变异成对人类更具威胁的另一种形式。世卫亚太地区发言人说，目前几乎可以确定，病毒以某种有限的形式在人与人之间传播。这位发言人还说，卫生专家在印尼发生死亡的村庄未能发现动物和家禽中有禽流感。


World Health Organization experts are studying what they say is the most significant development yet in the spread of the bird-flu virus -- the death of seven members of one family in Indonesia. Senior officials of the United Nations health agency say they are extremely concerned about the size and source of the outbreak in Indonesia. With seven deaths in the past three weeks and an eighth family member still infected with the H5N1 bird-flu virus, the case in northern Sumatra is the largest known human cluster of bird-flu infections.

WHO scientists who examined virus samples in Indonesia say they found no evidence of any mutation indicating that bird flu in Asia has changed to a form more dangerous to humans. However, a regional spokesman for the agency says it is almost certain there has been some limited form of human-to-human transmission of the disease. The spokesman says health experts can find no bird flu in animals or poultry in the village where the deaths occurred.
