claim: rapid increase of a sars-cov-2 variant with multiple spike protein mutations observed in the united kingdom.
evidence_1: the emergence of this variant raises concerns of a potential increase in transmissibility or propensity for sars-cov-2 re-infection of individuals.", "it is characterized by a spike protein mutation s: s477n, occurring in combination with n: m234i, a376t, orf1a: m3087i, orf1b: a176s, and most also with orf1b: v767l k1141r, e1184d.", "several new variants emerged in the fall of 2020, most notably: in the united kingdom (uk), a new variant of sars-cov-2 (known as 20i/501y.v1, voc 202012/01, or b.1.1.7) emerged with an unusually large number of mutations.",
