近日，俄羅斯學者們在一位免疫力低下的女子體內發現了18種變異新冠病毒，部分變種與英國出現的新型變異病毒相同，還有2種同丹麥水貂所攜帶的變異新冠病毒相吻合。據俄羅斯《消息報》12日報道，這位女子47歲，患有淋巴瘤。2020年4月，該女子在一次化療中感染新冠病毒。此後，她定期進行核酸檢測，在9月9日之前，檢測結果一直為陽性。
據介紹該女子體內出現的變異新冠病毒一部分同此前觀察到的免疫功能弱的患者的突變病毒相同，也和英國出現的新型變異病毒相同。此外，2種突變病毒還與丹麥水貂所攜帶的變異新冠病毒相吻合。西伯利亞聯邦大學基因組學與生物資訊學系教授康斯坦丁·克魯托夫斯基指出，這項研究工作首次確認了一個事實，即「新冠病毒在一個生物體內長期存在即會導致大量突變的出現」。同時，他指出，現在判定「俄羅斯」菌株的傳播速度為時尚早，因為只出現了這一個案例。
據俄羅斯新冠病毒防疫官網12日公佈的最新數據，俄羅斯新增22934例新冠肺炎確診病例，累計確診3448203例，新增新冠肺炎死亡病例531例，累計死亡62804例。
Recently, Russian scholars have discovered 18 mutated new coronaviruses in a woman with low inmuity . Some of the variants are the same as the new mutated viruses that appeared in the UK , and two of them are consistent with the mutated new coronaviruses carried by Danish mink. According to the Russian “Izvestia” report on the 12th , the woman is 47 years old and suffers from lymphoma. In April 2020 , the woman was infected with the new coronavirus during a chemotherapy session. Since then, she regularly nucleic acid detection , at 9 Yue 9 before date, test results have been positive.
According to reports, part of the mutant new coronavirus that appeared in the woman’s body was the same as the previously observed mutant virus in patients with weak immune function, and the same as the new mutant virus that appeared in the UK. In addition, the two mutant viruses are also consistent with the mutant new coronavirus carried by Danish mink. Konstantin Krutovsky, a professor in the Department of Genomics and Bioinformatics at Siberian Federal University, pointed out that this research work has confirmed for the first time the fact that “the long-term existence of a new coronavirus in an organism will cause a large number of mutations. “. At the same time, he pointed out that it is too early to determine the spread of the “Russian” strain because only this case has occurred.
According to the latest data released on the official website of Russia’s new crown virus epidemic prevention on the 12th , Russia has added 22,934 new confirmed cases of new crown pneumonia , a total of 3,448,203 confirmed cases, 531 new new crown pneumonia deaths , and a total of 62,804 deaths.
