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

Abstract

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.
