Coming to America: Genomic surveillance and how B.1.1.7 arrived in the US

Cell. 2021 May 13;184(10):2532-2534. doi: 10.1016/j.cell.2021.04.031.


In this issue of Cell, Washington et al. and Alpert et al. demonstrate the value of genomic surveillance when studying the introduction of the B.1.1.7 variant to the US and illustrate the challenge that results from the lack of good sampling strategies.
