Variants of severe acute respiratory syndrome coronavirus 2 raise concerns regarding the control of coronavirus disease epidemics. We analyzed 40,000 specific reverse transcription PCR tests performed on positive samples during January 26-February 16, 2021, in France. We found high transmission advantage of variants and more advanced spread than anticipated.
严重急性呼吸综合征冠状病毒 2 的变异引起了人们对冠状病毒病疫情控制的关注。我们分析了 2021 年 1 月 26 日至 2 月 16 日期间在法国进行的 40000 次针对阳性样本的特定逆转录聚合酶链反应检测。我们发现变异体具有很高的传播优势,其传播速度比预期的要快。
