For the scientists who have spent the past year poring over hundreds of thousands of coronavirus genomes, the United States has been an enigma. Despite having world-leading genome sequencing infrastructure and experiencing more COVID infections than any other country, the United States has until recently lagged far behind in sequencing coronavirus genomes and spotting worrisome variants.

B.1.1.7, first identified in Britain, has demonstrated the power to spread far and fast. In South Africa, a mutant called B.1.351 can dodge human antibodies, blunting the effectiveness of some vaccines.
