世界卫生组织于2009年5月12日说,甲型H1N1流感病毒存在变异成更凶猛病毒的可能性。同一天,世卫组织流感专家进藤奈邦子说,世卫组织很快将出临床指南,建议医生不要对所有患者都用抗病毒药,应将抗病毒药优先用于易受病毒攻击的高危人群。种种迹象表面,此次甲型H1N1流感来势汹汹并且可能在较长一段时间里还将继续造成全球性的影响,故而人们切不能掉以轻心。 On May 12, 2009, the World Health Organization said that the H1N1 influenza virus has the potential to mutate into more violent viruses. On the same day, WHO Flu Specialist Naito Fujimoto said that WHO will soon come out with a clinical guideline recommending that doctors not use antiviral drugs for all patients and that antiviral drugs should be given priority for the high risk of being vulnerable to viruses crowd. There are signs that the Influenza A (H1N1) virus is threatening and will likely continue to have a global impact over a longer period of time. Therefore, people should not be taken lightly.
