Brazilian lineage with variants of biological significants E484K, N501Y and K417T, described in recent virological posts: here and here. P.1 lineage is an alias of lineage B.18.104.22.168. As described in Rambaut et al., 2020 when the lineage heirarchy reaches a certain depth (length of 5) lineage names are given an alias to prevent them from becoming infinitely long.
This report is recent as of 2021-01-18 19:03 GMT. All SARS-CoV-2 sequences were downloaded from GISAID and genomes were de-duplicated based on GISAID sequence name – note that the publically available metadata may not fully allow us to de-duplicate by patient. Full data processing pipeline found here.
The sequences were then assigned lineages with pangolin v2.1.7, pangoLEARN version 2021-01-11.

Caveat: Most locations outside the original focus have not reported sustained transmission and many cases have known travel links to the focal location. Increasing numbers of international cases is currently likely due to increased surveillance and vigilance.
