尚未证实H7N9禽流感病毒可持续人际传播

2017-02-20 张淼 新华社

世界卫生组织驻华代表处2月17日表示,近来中国再次出现H7N9禽流感疫情,但还没有证据表明H7N9禽流感病毒具备持续性人际传播能力,减少接触感染病毒的活禽与关闭相关活禽市场是疫情防控关键。

世界卫生组织驻华代表处2月17日表示,近来中国再次出现H7N9禽流感疫情,但还没有证据表明H7N9禽流感病毒具备持续性人际传播能力,减少接触感染病毒的活禽与关闭相关活禽市场是疫情防控关键。

世卫组织驻华代表处在接受新华社记者书面采访时指出,自2013年首次在中国发现人感染H7N9禽流感病毒病例后,中国先后经历了5次H7N9禽流感病毒在冬春季的季节性流行。中国国家卫生计生委按国际要求通报了疫情信息。

世卫组织驻华代表处说:“绝大多数患者通过接触感染病毒的禽类或活禽市场等环境感染了H7N9病毒。基于现有报告的信息,没有证据表明该病毒具备持续性人际传播能力,病毒属性和患者的病理学特征也没有显着改变。”

世卫组织驻华代表处表示,只要禽流感病毒在禽类中存在,出现偶发性人类感染病例或小规模疫情的可能性也就存在。考虑到禽流感病毒可能会持续演变和重组,人们对新出现的禽流感病毒保持警惕尤为关键。

该机构称,中国建立了发现与报告H7N9禽流感等传染病的体系,并且有能力分析病毒的变化发展。此次禽流感疫情暴发后,中国政府宣布采取多项措施强化监测与疫情防控,其中包括关闭相关活禽市场。此前禽流感疫情防控中,关闭活禽市场与保持市场卫生安全的举措发挥了重要作用。

世卫组织驻华代表处表示,对普通大众而言,重要的是做好预防工作。鉴于普通大众很难断定禽类感染了何种类型的禽流感病毒,因此人们在处理、宰杀和准备食用禽类时需要执行严格的卫生安全措施。(张淼)
