我们对最近出现的 SARS-CoV-2 变种的传播进行了全球分析,并使用 GISAID 的序列数据估计了特定国家水平的有效繁殖数的变化。几乎所有接受调查的国家都表现出世界卫生组织指定的关注变种迅速取代了以前流行的谱系,预计 B.1.1.7 的传播率分别增加了 29%(95% CI:24-33)、25%(95% CI:20-30)、38%(95% CI:29-48)和 97%(95% CI:76-117)。 B.1.351、P.1 和 B.1.617.2。
We present a global analysis of the spread of recently emerged SARS-CoV-2 variants and estimate changes in effective reproduction numbers at country-specific level using sequence data from GISAID. Nearly all investigated countries demonstrated rapid replacement of previously circulating lineages by the World Health Organization-designated variants of concern, with estimated transmissibility increases of 29% (95% CI: 24–33), 25% (95% CI: 20–30), 38% (95% CI: 29–48) and 97% (95% CI: 76–117), respectively, for B.1.1.7, B.1.351, P.1 and B.1.617.2.
