【冠状病毒19】俄罗斯女子体内发现多达18种变异病毒
根据俄罗斯《消息报》报导,俄罗斯研究人员在一名47岁,患有淋巴瘤的女子体内中发现多达18中变异病毒。
据了解,女子去年4月在一次化疗中染疫,但截至9月9日前,其检测结果一直为阳性。
而在她体内发现的变异病毒,与此前所观察到在免疫功能较弱的患者的突变病毒相同,且部分变种毒株与英国的变异毒株相同。
另外她体内还与两种同丹麦水貂所携带的变异毒株吻合;但她和水貂相关感染群并无关联。
对此,西伯利亚联邦大学基因组学与生物信息学系教授康斯坦丁指出,这是首次确认,冠病病毒在生物体内长期存在,即会导致大量突变出现。
但他也指出,现阶段判定俄罗斯毒株有传播现象,还为时过早,因为目前仅限一例。
截至昨日(12日)俄罗斯目前共有近345万起确诊病例,仅次于美国、印度和巴西,死亡病例多达6万2804起。
