世卫组织:新冠病毒变异后的影响还未确定

世卫组织举行新冠肺炎例行发布会,世卫组织卫生紧急项目负责人迈克尔·瑞安表示,新冠肺炎大流行以来,不同动物感染过新冠病毒,也有可能再传回人类。令人担心的是,水貂这样的哺乳动物是很适合新冠病毒的动物宿主,新冠病毒可能在这些物种内逐渐变化。需要在农场内确保生物安全,避免新冠病毒再从动物传给人类。现有证据显示,变异后的新冠病毒行为并无不同,只是在具体特征上可能有轻微区别,但仍是同一种病毒,其具体影响还需要很长一段时间才能确定。

世卫组织首席科学家苏米娅·斯瓦米纳坦表示,世卫组织已对超过17万个新冠病毒基因序列展开追踪,还没证据显示此次水貂体内新冠病毒出现的变异会影响疫苗效力,目前尚不能得出结论。
