Monitoring the SARS-CoV-2 B.1.1.7 lineage in Tenerife (Spain) between 18th of December 2020 and 25th of February 2021. (A) Accumulated incidence per 100,000 inhabitants in the last 14 days (AI 14 days) and spike gene target failure (SGTF) cases per day in the study period. (B) Maximum likelihood phylogenetic tree of SARS-CoV-2 sequences characterized by the spike gene target failure (SGTF) in the period (B.1.1.7 lineages in red; other lineages in blue). The tree also includes relationships with other 1902 genome sequences representative of major clades, labelled based on Nextstrain definitions, from Auspice v2.23.0 (as of 2021-03-07) and sampled between December 2019 and March 2021 for reference (light gray) (For interpretation of the references to colour in this figure legend, the reader is referred to the web version of this article.).
