致死率很高的新型H7N9病毒,在2013年的春天,唤醒了人们十年前的梦魇。截至4月10日,全国检测H7N9患者33例,死亡9例。虽然中国政府信息公开和积极应对赢得各方的称赞,但H7N9莫测的传播方式、超过30%的死亡率还是让人们依稀看见SARS的影子。面对高速变异的病毒,科学家和医生们无法拿出一劳永逸的方案。于是,一次次公共卫生事件的发生,与新病毒斗争的同时,也往往是为公众普及科学知识的良机。 The new fatal H7N9 virus, in the spring of 2013, awakened the nightmare of a decade ago. As of April 10, 33 cases of H7N9 were detected nationwide, 9 of them died. Although the open and positive response from the Chinese government won the praise of all parties, the unpredictable transmission mode of H7N9 and the death rate of more than 30% still make people vaguely see the shadow of SARS. The face of high-speed mutation of the virus, scientists and doctors can not come up with once and for all solutions. As a result, time and again public health incidents, fighting new viruses, but also often is an opportunity for the public to popularize scientific knowledge.
