states.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.The increased transmissibility of the B.1.1.7 variant warrants universal and increased compliance.
