关于此主题，我们已经了解了哪些信息？在美国12个州发现了一种传播性更高的SARS-CoV-2变种B.1.1.7。这份报告补充了什么？建模数据表明，B.1.1.7有可能在未来几个月内增加美国的大流行轨迹。疾病预防控制中心的基因组监测系统和扩大测序的努力将增加及时获得美国基因组监测数据的机会。B.1.1.7变体的传播性增加，需要普遍和更多地遵守缓解策略，包括距离和掩蔽。可能需要实现更高的疫苗接种覆盖率以保护公众。通过国家SARS-CoV-2毒株监测计划进行的基因组序列分析将能够有针对性地识别美国关注的变异。
What is already known about this topic?A more highly transmissible variant of SARS-CoV-2, B.1.1.7, has been detected in 12 U.S. states.What is added by this report? Modeling data indicate that B.1.1.7 has the potential to increase the U.S. pandemic trajectory in the coming months. CDC's system for genomic surveillance and the effort to expand sequencing will increase the availability of timely U.S. genomic surveillance data.What are the implications for public health practice?The increased transmissibility of the B.1.1.7 variant warrants universal and increased compliance with mitigation strategies, including distancing and masking. Higher vaccination coverage might need to be achieved to protect the public. Genomic sequence analysis through the National SARS-CoV-2 Strain Surveillance program will enable a targeted approach to identifying variants of concern in the United States.
