FIG. 1.

Phylogenetic overview of SARS-CoV-2 in Europe through the end of November. The tree shows a representative sample of isolates from Europe colored by clade and by the variants highlighted in this paper. A novel variant (orange; 20E (EU1)) with mutation S:A222V on a S:D614G background emerged in early summer and is common in most countries with recent sequences. A separate variant (20A.EU2, blue) with mutation S:S477N is prevalent in France. On the right, the proportion of sequences belonging to each variant (through the duration of the pandemic) is shown per country. Tree and visualization were generated using the Nextstrain platform (Hadfield et al., 2018) as described in methods.
