Fig. 2: Posterior estimates for the relative importance of lineage introduction events in 10 European countries.
From: Untangling introductions and persistence in COVID-19 resurgence in Europe
We report three summaries (posterior mean and 95% HPD intervals) for each country: the ratio of unique introductions over the total number of unique persisting lineages and unique introductions between 15 June and 15 August 2020 (1), the ratio of descendant lineages from these unique introduction events over the total number of descendants circulating on 15 August 2020 (2) and the ratio of descendant taxa from these unique introductions over the total number of descendant taxa sampled after 15 August 2020 (3) (see Extended Data Fig. 4). The dots are numbered and the sizes are proportional to: (1) the total number of unique lineage introductions identified between 15 June and 15 August 2020; (2) the total number of lineages inferred on 15 August 2020; and (3) the total number of descendant tips after 15 August 2020.
