SARS-CoV-2谱系B.1.1.7是2020年9月在英国首次发现的一种变异病毒,目前已传播至全球多个国家。一些研究已经确定B.1.1.7比先前存在的变体更具传播性,但尚未确定它是否会导致疾病严重程度的任何变化。在这里,我们分析了一个数据集,该数据集将2020年11月1日至2021年2月14日英格兰2,245,263例SARS-CoV-2阳性社区检测和17,452例与COVID-19相关的死亡联系起来。对于这些检测中的1,146,534(51%)例,可以确定是否存在B.1.1.7,因为该谱系中的突变阻止了S基因靶标的PCR扩增(称为S基因靶标失效(SGTF))。基于已知SGTF状态的4,945例死亡,我们估计在调整年龄、性别、种族、贫困、居住在护理院、当地居住当局和检测日期后,SGTF相关死亡风险比无SGTF的病例高55%(95%置信区间,39-72%)。这对应于在社区中阳性检测的28天内,55-69岁男性的绝对死亡风险从0.6%增加到0.9%(95%置信区间,0.8-1.0%)。校正SGTF的错误分类和SGTF状态的缺失,我们估计与B.1.1.7相关的死亡风险比预先存在的变体高61%(42-82%)。我们的分析表明,B.1.1.7不仅比先前存在的SARS-CoV-2变体更具传播性,而且还可能导致更严重的疾病。
SARS-CoV-2 lineage B.1.1.7, a variant that was first detected in the UK in September 2020, has spread to multiple countries worldwide. Several studies have established that B.1.1.7 is more transmissible than pre-existing variants, but have not identified whether it leads to any change in disease severity. Here we analyse a dataset that links 2,245,263 positive SARS-CoV-2 community tests and 17,452 deaths associated with COVID-19 in England from 1 November 2020 to 14 February 2021. For 1,146,534 (51%) of these tests, the presence or absence of B.1.1.7 can be identified because mutations in this lineage prevent PCR amplification of the spike (S) gene target (known as S gene target failure (SGTF)). On the basis of 4,945 deaths with known SGTF status, we estimate that the hazard of death associated with SGTF is 55% (95% confidence interval, 39–72%) higher than in cases without SGTF after adjustment for age, sex, ethnicity, deprivation, residence in a care home, the local authority of residence and test date. This corresponds to the absolute risk of death for a 55–69-year-old man increasing from 0.6% to 0.9% (95% confidence interval, 0.8–1.0%) within 28 days of a positive test in the community. Correcting for misclassification of SGTF and missingness in SGTF status, we estimate that the hazard of death associated with B.1.1.7 is 61% (42–82%) higher than with pre-existing variants. Our analysis suggests that B.1.1.7 is not only more transmissible than pre-existing SARS-CoV-2 variants, but may also cause more severe illness.
