北京确诊首例H7N9病人 H7N9禽流感在中国首都北京确诊的首例病例是一名7岁女童。 据官方报纸新华日报报道，在所有43个病例中，其中11个致命的都发现于华东地区。 新华日报称最后发现的病例是由当地卫生机构汇报，并由中国疾病控制和防疫中心确诊的。 中国官方在2周前首次宣布这种疫情在人类身上发生。 卫生部门说他们不确定疫情是怎么扩散的，相信应该是在中国一部分城市由于家禽而引发。 自从上海确定20个病例以来已经停止买卖和宰杀活家禽，其他一些华东城市也纷纷效仿。 专家担心这种病菌会变异为一种更容易在人类彼此之间传播的病菌从而引起大型瘟疫。 本周世界卫生组织宣称并没有证据显示禽流感在人类彼此之间传播的迹象。 世界卫生组织的分属机构动物健康机构在星期四说：“H7N9禽流感出现一个特殊的情况，这种病菌虽然危机人类，但并未发现对鸟类有任何影响。 中国宣称在接下来的几个月应该可以研制出疫苗。 http://www.abc.net.au/news/2013- ... ustralianetworknews Beijing confirms first case of H7N9 bird flu A seven-year-old girl in Beijing has been infected with H7N9 bird flu, the first confirmed case in the Chinese capital. Until the announcement, which came via the state-run news agency Xinhua, all 43 previous human cases of the H7N9 outbreak - 11 of which have been fatal - had been confined to eastern China. Xinhua said the latest infection was announced by local health authorities and was confirmed following a test by the Chinese Centre for Disease Control and Prevention. China officials announced nearly two weeks ago that they had found the strain in humans for the first time. Health authorities in the country say they do not know exactly how the virus is spreading, but it is believed to be crossing to humans from birds, triggering a mass culling of poultry in several Chinese cities. Shanghai has had 20 confirmed cases so far and was the first to halt trading in live poultry and cull birds last week, followed by other cities in eastern China. Experts fear the prospect of such viruses mutating into a form easily transmissible between humans has the potential to trigger a pandemic. The World Health Organisation (WHO) said earlier this week that there was as yet no evidence of human-to-human transmission. The World Organisation for Animal Health (OIE) on Thursday said H7N9 bird flu posed an "exceptional situation", explaining that the virus, while dangerous to humans, was hard to detect in the avian host. China has said it expects to have a vaccine ready in seven months. |
